Use an image as mask only where pixels are opaque We are into a game where to build our tile map, we carve on an image with a mask (At first the whole map is an image, and we create holes on it with tiles to create the map and le the background show. It is like substracting instead of adding new tiles in any common tiled based game). We have done this with just a tile that acts as a mask using stencil buffer. The problem comes when we want to mask with tiles where all their pixels are not opaque, for example a slope. The problem is that it applies the mask as if all the pixels in tile where opaque and we want to apply the mask in two differnet ways 1) Keep the pixels of the big image where the mask pixels are opaque 2) Mask the pixels of the big image where the mask pixels are transparent (alpha 0) I have read a lot of info about using stencil and alpha blending but can't make it work. Checking the pipeline order it seems that stencil is applied after the fragment color has been calculated. Is it possible to access the alpha value at stencil stage and write to the stencil as needed to just mask part of the image (tile in my case). Update to add a visual example

How do I run code for a period of time and then return to normal behavior? i wanna run a code for my special power for five seconds only and then return to my normal working. when that power activates i am changing my player's material and i wanna return to my old material after those five secs are over. this is the code i tried void Start () transform.GetComponent lt Renderer gt ().material.mainTexture texts 0 void Update () if (condition) for (int t1 0 t1 lt 5 t1 (int)Time.deltaTime) transform.GetComponent lt Renderer gt ().material mats 0 transform.GetComponent lt Renderer gt ().material.mainTexture texts 0 this code breaks the game i think because unity is freezing when the condition is being met.

Unity how to put a target under a character's feet that follows ground model contours? In my current projects, one of the power ups needs to place a target marker centered on the position of the player triggering it the actual design for this is TBC, but will be a circle with a radius of 10 units. The ground for the playing arena is a model, and not flat. Assuming that I use a texture to show this target area, how can I have this texture render following the contours of the ground? Alternatively, any other approach to solving this would be appreciated. Thank!

How to temporarily increase the speed of a character in a Unity game As the title would suggest, I want to give a character a speed boost for x amount of seconds, while increasing their Gameobject's mass. During this little speed boost, I also want to add a script to another player that disappears when the speed boost dies out I am new to C , and Unity in general, any help would be appreciated. using System.Collections using System.Collections.Generic using UnityEngine public class PlayerAddMass MonoBehaviour Start is called before the first frame update void Start() Update is called once per frame void Update() if (Input.GetKey(KeyCode.Q)) rb GetComponent lt Rigidbody gt () rb.mass 10 rb GetComponent lt Rigidbody gt () rb.speed 5 The code above was found on a unity website of some sorts, and I modified it to set the speed and mass numbers (I changed the 0s into a 10 and a 5) The errors I get are "rb does not exist in the current context" x 4

Shader Directional Lights Depth Is there a way to retrieve the deph from directional lights ? I can access the ShadowMapTexture but this is not the depth. I found how to access the shadow map of, I think, every light type by using the defines such as SHADOW ATTENUATION(a) or directly the ShadowMapTexture, everything is located in the built in shaders. But I am wondering how could I access the depth of those lighting type. I found a way to access it for the spot light this way ShadowCoord.z which gives the depth scaled with ShadowCoord.w, which could be considered to the far plane, but am I right ? How could I do the same for the other light types such as directional or point lights ? For the moment I am stuck with directional lights, any clues ? Because if I try to access the depth for a directional light by using ShadowCoord.z it seems that it's more related to the depth view and not the light. Here I am, totally stuck with this directional lights.

Implementing Skyrim's save system in Unity Unity has it's own way of saving in which you can add values and any type of information to the registry and it will be saved for future use. However what happens when you try to create a more complex save system such as the one featured in Skyrim. In this case it even get's a screenshot of the moment you pause the game to save and uses it to identify the save file. Also all the current actions the user and the npcs where doing at the moment gets save. How can I implement this complex save system into unity using it's current way of handling save data?

UnityEvent Array coding C I am fairly new to Unity 5, as I was browsing through some prefabs, I found one for the Main menu in which UnityEvent was used in scripts to list down the menu options. This UnityEvent was an array UnityEvent Event, which was nowhere initialized to anything but was showing no compiler errors and also during run, it was pointing to some predefined sets which the author was mentioning in the user manual... My questions are Is it possible to use UnityEvent Array without mentioning the size of the array. What happens to the UnityEvent if we don't mention any of the events, but the Invoke functionality is called during runtime. Btw, the prefab i used from was Main Menu with Parallax effects

Making a zoom out in space map in Unity I'm new to unity, I was wondering how would one go into implementing a dynamic 2d space map. Let me give you an example what i mean. You see our solar system on the map, if you zoom out at a treshold value this solar system would just be represented by a name and our sun and around it you see adjacent solar systems. How would I do this in unity?

My player sprite get stuck to walls while moving along Hello, My player sprite is moving along the wall (not even diagonal, just straight down) and get randomly blocked in the corner of some walls. By blocked, I mean that the Y movement is stopped. If I move him away from the wall, he might not be blocked again by the same wall and get blocked at some other walls, always at a corner. The walls are all the same sprite and are of the same size. I use 2D Box Colliders for the walls. The player sprite has a Box Collider 2D and a RigidBody 2D. I am not using any physics codes, I would just like to make it work with the built in Unity physics. I move the player by adjusting the velocity of the rigidbody according to Input RigidBody2D rb GetComponent lt Rigidbody2D gt () float horizontal Input.GetAxisRaw ("Horizontal") float vertical Input.GetAxisRaw("Vertical") Vector2 movement new Vector2(horizontal, vertical).normalized speed Time.deltaTime this.rb.velocity movement The player is set like this Do you have any idea why it behaves like this and how I could fix it? Thanks for your help.

Why it isn't possible to get a progress in SceneManager.LoadSceneAsync between 0.0 and 0.9? I am trying to understand why does SceneManager.LoadSceneAsync progress always jumps from 0.0 to 0.9, no matter how big a scene can be. To try trigger smoother progress of the scene being loaded, I've tried the following Generate a large scene from an EditorWindow, containing tens of thousands of objects referencing thousands of assets. Loading this scene didn't produce the intended behavior, rather, it ended up being exactly the same (jumps from 0.0 to 0.9) but with a huge lag at the end since there are many objects. According this behavior, I am now considering that the supposed asynchronicity in SceneManager.LoadSceneAsync is just about the loading of the scene file itself, not processing its content for being usable by Unity. Is this correct? An example on how to load a large scene and report its progress would be appreciated )

Render object transparent with camera instead changing object render mode I have a pretty large area where I want to show the floor with 60 transparency using a so called Opacity camera (an idea). I know I can set mesh rendering mode to transparent and then decrease the alpha value. My question is that, is there any way available to apply mesh transparent rendering setting to my camera instead of the object.

Loading images using their bytes in Unity If you import an image into the Unity inspector, the image will be encoded in Unity's own format. Usually the resulting image is much bigger than the original (from 100kb to 1MB). Of course, you can do stuff like compress and change the texture max size to reduce the image's size, but at the end it will almost always be bigger. I noticed that you can create a Texture2D if you got the necessary bytes. As an experiment, I took my 100kb image and imported it to Unity as a .bytes file. Then I read the bytes and created my Texture2D Texture2D texture new Texture2D(100, 100) texture.LoadImage(myTextAsset.bytes) Sprite sprite Sprite.Create(texture, new Rect(0,0,350, 288)) And it works. And it is smaller (100kb). So my question is what's the difference between Unity's builtin way of handling images and my way of loading them using their bytes? Because I'm saving tons of memory with this method. I imagine that it is a bit slower. But if that's the only difference, I can live with that.

How can I add two Vector3 directions together? I have a direction to my target object, which is in a Vector3 format. I want cast a number of rays, as offsets from this initial direction. X is the object. D is the direction the player needs to travel in. A amp C are other directions that I want to cast rays towards to check for impacts. A D C x I was trying to add an offset, such as Vector3.Right to the Direction and then normalise the result, however this only works if everything is oriented towards World Space. So how can I convert and add a direction (Vector3.right) as an offset to an existing direction? I'm fairly sure I just have World Space and Local Space directions mixed up but can't see an easy way to convert between this with Vector3?

How to execute code every x seconds in unity? So I have a flashlight battery script I created and I need to know how do you make the battery variable go down every few seconds(whatever time you set.)

How to show specific item in question on trigger entry? (Unity c ) So I have multiple, random objects on a plane, and when my player walks into them, I want them to be 'picked up'. The player can only hold one object at a time, and needs to return the item to the base before he can pick up another. Using the OnTriggerEntry function in a collider script, a set of commands are called when the player touches the object. Within the function, the 'itempickup' function from the player script is called using 'col.transform.SendMessage()'. How do I tell the itempickup function which specific object was 'picked up' in the trigger script? That is, is there a variable of some kind that acts as an ID for game objects? Thanks )

Blender Unity Import Animation Failing by Overlapping Mesh Objects I'm new to both Unity and Blender. I created this penguin 3d model, rigged it up and animated it in Blender and all looked good. When I imported it into Unity, I noticed that this idle animation did not appear to be working correctly. As the body moves, the body mesh overlaps the belly mesh and covers a portion of it. This is not the case when viewing the animation from blender 2.9. The belly uses a shrinkwrap modifier with the body as a target. Is this a problem with Unity import, or how I modeled this penguin in Blender? Can anyone see what I have done wrong here? Any help is much appreciated!

How can I change a materials properties in my Unity c code? Hello everyone I want to change my materials tiling offset in code, but the only way I found to access it other than drag dropping to a public field in inspector is to check by name. But I then noticed the name is suffixed with ' (Instance)' . So it seems a little odd to me having to access it this way, is there another way that I don't know about? foreach(Material m in GetComponent lt MeshRenderer gt ().materials) if (m.name "card front (Instance)") m.mainTextureOffset new Vector2(value 1 13f, (int)suit 1 5f)

How to create a boxcollider, which surrounds the gameobject and all of his children? I have a Car, who needs a Box Collider. If the car would be 1 single mesh, i would only need to call boxCol gameObject.AddComponent lt BoxCollider gt () and it would create a boxCollider, which fits perfectly my car, based on my car's mesh. Now I have a car which exists of many different parts in the hierarchy. (for example Body of the car is the parent of the 4 doors. Every door is 1 seperate gameobject, and has a doorknob child etc. ) now i need a script which changes the boxCollider so, that it has the box surrounding the whole car. i found http answers.unity3d.com questions 22019 auto sizing primitive collider based on child mesh.html but it just doesnt get me the right collider. Edit I just tried again and the Boxcollider stays the same. using UnityEngine using UnityEditor using System.Collections public class ColliderToFit MonoBehaviour MenuItem("My Tools Collider Fit to Children") static void FitToChildren() foreach (GameObject rootGameObject in Selection.gameObjects) if (!(rootGameObject.GetComponent lt Collider gt () is BoxCollider)) continue bool hasBounds false Bounds bounds new Bounds(Vector3.zero, Vector3.zero) for (int i 0 i lt rootGameObject.transform.childCount i) Renderer childRenderer rootGameObject.transform.GetChild(i).GetComponent lt Renderer gt () if (childRenderer ! null) if (hasBounds) bounds.Encapsulate(childRenderer.bounds) else bounds childRenderer.bounds hasBounds true BoxCollider collider (BoxCollider)rootGameObject.GetComponent lt Collider gt () collider.center bounds.center rootGameObject.transform.position collider.size bounds.size

Determine Mesh Vertex Index Given Another Mesh Index Please bare with me as I explain what I am trying to accomplish P Each 'X' below represents a mesh vertex For my Unity3d GameObject (G1) the mesh vertices are stored in a C List object in the following order. Note the mesh index 'A'. This is a value I know in this case A 16 (mesh index 16). I have another GameObject (G2) whose shape is the same (a simple rectangle) but the mesh vertices are ordered differently. Note the mesh index 'B'. This is a value I dont know and I want to find this value (mesh index) in this case B 17 (mesh index 17). As you can see the mesh arrangement is pretty much the same except rotated 90 degrees. If I know the 'mesh vertex index' of A how can I find the 'mesh vertex index' of B? Whats an algorithm that can calculate the mesh index of B? My attempt is not working at all uint A 16 uint nCols 6 uint nRows 4 Technically both B and A sit on Row 3, Column 5 so if I can find A's row and column maybe I am there? uint aCol 16 nCols nup not right uint aRow (16 nCols) 1 gives 3 Once I've calculated aCol and aRow its easy uint B (aRow nRows) aCol ie, (3 4) 5 17

Why is my sine based scale animation not changing? I followed the code at this YouTube channel https www.youtube.com watch?v OR0e 1UBEOU amp t 4178s, and did some modification on the code so that the scale of the bird will change during projectile using the absolute sine function under the if statement.

How do you reference one game object from another? I am trying to reference a game object that was created in the editor and added to the scene (not created dynamically). How can I reference this object in a script added to another gameobject? For example I have a Mesh called QuantumCold B (in the editor), and I try to get its position in a script to be added to First Person Player, but instead I get Unknown identifier ('QuantumCold B'). Here is my script function Update () transform.RotateAround(QuantumCold B.position, Vector2,20 Time.deltaTime) Also is position the right way to get the Vector position on QuantumCold B?

Transactions on lists of coins of different values For learning purposes, I am developing the first steps of an idle game with exponentially higher income numbers. Usual int, long, etc. can't store big enough numbers for that. I looked through many threads which I found on google and using a list (or an array) which is separated in e.g. bronze coins, silver coins, gold coins, etc. seems to be the cleanest version. In my first approaches I created this list namespace Coins public class script coinHandler MonoBehaviour public List lt Coin gt coinList new List lt Coin gt () list based on the quot Coin quot class new Coin() Name quot bronze quot , new Coin() Name quot silver quot , new Coin() Name quot gold quot , new Coin() Name quot diamond quot , public class Coin public string Name get set public int Amount get set public int Multiplier get set I want each coin type to go up to 999999. This means 1 silver 1000000 bronze, 1 gold 1000000 silver. I can't get my head around a way to do maths with this list. Example Player has 3000 GOLD, 320000 SILVER, 524321 BRONZE Player wants to buy something for 20 GOLD, 120000 SILVER, 300000 BRONZE Just subtracting 20 from GOLD, 120000 from SILVER, and 300000 from BRONZE won't always work. For example when a Player has no BRONZE but some SILVER you can't subtract 300000 BRONZE without converting SILVER to BRONZE first. Q What would be an efficient function to subtract the price from the total amount? What about multiplying and dividing? Accuracy is not important. When spending a few GOLD, nobody will care about 10000 BRONZE.

Only 1 TextMeshProUGUI being affected by coroutine I have a prefab m wordContainer which is empty other than having a TextMeshProUGUI as a child (I did this so that I could position this container freely not being bugged by an animation played by the TMPUGUI object). At the start of the program I start a coroutine (SpawnWordPopups) which splits the words in a sentence, making a copy of m wordContainer and assigning that word to the text property of its TMPUGUI, spawning such m wordContainer in a random location within the screen, and then starting a coroutine (FadeText) that fades in the text of every TMPUGUI. The problem is that only one of the TMPUGUI has its text faded, even though the FadeText coroutine is called seemingly correctly. All words are shown as expected, only thing missing is the fading effect on all but the first word that fades. If I called FadeText like this if (i gt 0) yield return FadeText(true, tmpText, 2) then only the second word will be faded. SerializeField private GameObject m wordContainer void Start() yield return StartCoroutine(SpawnWordPopups( quot test foo bar quot )) private IEnumerator SpawnWordPopups(string l line) string words l line.Split(' ') List lt Vector3 gt wordPositions new List lt Vector3 gt () for (int i 0 i lt words.Length i) Vector3 spawnLocation new Vector3(Random.Range(m wordScreenDistanceOffset, Screen.width m wordScreenDistanceOffset), Random.Range(m wordScreenDistanceOffset, Screen.height m wordScreenDistanceOffset), 0) if (IsWordOverlapping(wordPositions, spawnLocation)) i continue wordPositions.Add(spawnLocation) GameObject wordContainer Instantiate(m wordContainer, transform.parent) wordContainer.transform.position spawnLocation TextMeshProUGUI tmpText wordContainer.GetComponentInChildren lt TextMeshProUGUI gt () tmpText.text words i yield return FadeText(true, tmpText, 2) private IEnumerator FadeText(bool l fadeIn, TextMeshProUGUI l textBox, float l time) float time Time.time float until Time.time l time int alphaFrom l fadeIn ? 0 1 int alphaGoal l fadeIn ? 1 0 Color textColor l textBox.color textColor.a l fadeIn ? 0 1 l textBox.color textColor while (time lt until) textColor l textBox.color textColor.a Mathf.Lerp(alphaFrom, alphaGoal, Time.time l time) l textBox.color textColor time Time.deltaTime yield return null textColor.a l fadeIn ? 1 0 l textBox.color textColor Could anyone shed some light into this issue I'm having?

Adding some new velocity to player in FixedUpdate. Should I use FixedDeltaTime or nothing? I am trying to learn how to move objects in Unity without using the built in features like AddForce etc. Some tutorials on Unity website (and other places) is where I have got most of my 'knowledge' so far from. This script for moving players (in topdown Space SHMUP) has been working fine for me and includes acceleration and artificial drag (basically 'smooth' movement, or like being on ice). I'm sure this code is overly long, bloated, inefficient and in most cases downright wrong, but it is written for me to understand it, rather than simply using Unity Prefabs and AssetPackages i download from Store. QUESTION Do I need the Time.fixedDeltaTime mutlipiers when calculating my 'delta v' values here. And also what about on the drag part at the bottom. As usual all help and comments are greatly appreciated. Thanks! public class Player Movement SpaceShooter TopDown MonoBehaviour public Vector2 maxVelocity public float drag public float moveForce private Rect moveBounds private Rigidbody2D rb private void Start() rb GetComponent lt Rigidbody2D gt () moveBounds Game Manager.instance.ScreenBounds private void FixedUpdate() float input h Input.GetAxis("Horizontal") float input v Input.GetAxis("Vertical") Vector2 delta v Vector2.zero delta v.x input h moveForce Time.fixedDeltaTime delta v.x Mathf.Clamp(delta v.x, maxVelocity.x, maxVelocity.x) delta v.y input v moveForce Time.fixedDeltaTime delta v.y Mathf.Clamp(delta v.y, maxVelocity.y, maxVelocity.y) Vector2 pos rb.position Vector2 vel rb.velocity if (pos.x lt moveBounds.xMin) pos.x moveBounds.xMin vel.x 0f if (pos.x gt moveBounds.xMax) pos.x moveBounds.xMax vel.x 0f if (pos.y lt moveBounds.yMin) pos.y moveBounds.yMin vel.y 0f if (pos.y gt moveBounds.yMax) pos.y moveBounds.yMax vel.y 0f rb.position pos rb.velocity vel delta v rb.velocity rb.velocity (1 Time.fixedDeltaTime drag) It appears to me that if FixedUpdate was somehow slowed down, the velocity would get changed slower, the same with the enemy movement but I don't know how that would effect the gameplay and if how the slowing down would occur

Selective Image Effects with Stencils I am trying to create an image effect where only a part of the image has the effect applied to. One way I can think of to do this is to define the portion of the image using the stencil buffer. Stencil Mask Shader Stencil Ref 1 Comp always Pass replace Image Effect Shader Stencil Ref 1 Comp equal Pass keep OnRenderImage Function void OnRenderImage(RenderTexture source, RenderTexture destination) saturationPassMat CheckShaderAndCreateMaterial(saturationShader, saturationPassMat) saturationPassTex RenderTexture.GetTemporary(source.width, source.height, 24) Graphics.SetRenderTarget(saturationPassTex.colorBuffer, source.depthBuffer) Desaturate(source, saturationPassTex, saturation) Graphics.Blit(saturationPassTex, destination) Applying the stencil portion of the image effect shader to any other object produces a desirable stencil effect (aka it works). The Problem By the time OnRenderImage is called, it seems that the stencil buffer has already been cleared. Changing Ref to 0 in the Image Effect shader will apply the effect to the entire screen. Any other value will result in a black screen. This can only mean that the stencil buffer has been cleared to 0. Is there a way to prevent the stencil buffer from clearing? Or is this the right method to use the stencil buffer with image effects? Or perhaps there are other solutions that are still efficient, without the use of Stencils?

How to use an overlapping shader so that it uses layers sort from sprite renderer and its transparent Im using the shader from question , but once I put it in the game, and my character gets close to it, it will be hidden by the shadow of the tree, which is transparent. Any way to make the shader transparent and or maybe use the sprite renderer sort layer system I have been trying to use stencil configurable shader with no luck Thank you for your help Not sure what combination of these should work The character is using a normal sprite renderer.

Reused Avatar moves mesh I have a humanoid avatar and it's animation controller. I also have two different human meshes, they're quite similar. When I use the generic avatar and it's controller in the animator the meshes shot out into the sky and perform their animation correctly. The animations run normal they just move in weird directions and don't stay in their original locations. How to fix it so the mesh doesn't move far away and retain original position?

Best practice for 4x game management in Unity? I'm trying my hand at creating a turn based 4x game in Unity, with a galaxy map and 2D hexagon grid maps for each individual planet. The planet grid hexes would be gameobjects, with the overall grid being around 30x40 in size. The number of planets would be under 50. What would be the best way to set this up? I'm looking for a solid approach regarding performance here, but one that also caters to easier design programming would be a plus. Some approaches I've come up with Load all of the grids for the individual planets at the start into a single scene, with each being under a "planet gameobject", and then set those gameobjects to inactive. The galaxy map would be its own scene that is loaded additively when needed clicking on a planet to view it would set its associated gameobject to active and then unload the galaxy map scene. Instantiate the gameobjects for planets as they're called up the grid data for the planet is dynamically loaded as part of this. The planet gameobject is destroyed when no longer needed. Galaxy map would function the same as approach 1. Individual scenes for each planet, loaded unloaded additively when needed. A separate, single scene would be used for loading procedurally generated planets. Seems to have serious challenges for managing units resources across planets scenes. Approach 1 seems to be the most straightforward, as the core of the game would be managed in a single scene, but I am concerned about performance. I'm setting up some test projects to stress test the approaches, but it'd be great to get feedback from someone with more experience. Any help is appreciated!

How do I get an object to rotate in world space via RigidBody.AddTorque? I'm getting really discouraged because I can't seem to figure how how to rotate my object via Rigidbody.AddTorque like it is on a figurative global turn table rather than a local turn table. Another way of describing it is that I want to c calculate a torque vector that will rotate the object's yaw and keep it upright regardless of its pitch without rolling it around. This is a problem for me because I want my player to remain upright without ending upside down because they were pitched and decided to turn. Someone else had posted about the same problem on a different forum but he didn't receive much in the line of help, however he did provide this really helpful image describing the problem Notice how the left object is tilted and then rotating with respect to its own local coordinates but the one on the right is rotating with respect to the global coordinates instead of rolling around like the one on the left. How can I achieve this? Is there something obvious I am overlooking or forgetting? Am I explaining it right? EDIT In the following image the top half illustrates what I want while the bottom half is showing what is actually happening. What I want is to be able to tilt the player's pitch and have them be able to rotate almost like a turret. I was able to accomplish this for demonstration purposes by first rotating the player and then pitching. Instead what I am getting is if the player tilts their pitch and then turns they start to bank, or in other words they start to roll. My code looks something like this rigidBody.AddTorque(Vector3.up horizontal RotateImpulse Time.fixedDeltaTime, ForceMode.Impulse) rigidBody.AddTorque(Vector3.right vertical RotateImpulse Time.fixedDeltaTime, ForceMode.Impulse) I sincerely appreciate you all offering to help me with this.

How to make a gui button follow a path after a touch? I would like a button in my gui menu to follow a specific path if we selected it, I am wondering how I could do it if we touch the button, then it can only move on the specific path, it is an arc such as this path Would you know how to achieve this? I am using Unity, but I think the theory should be the same for other software language ? Thanks for your help EDIT here is the code for the bezier curve in unity Where should I put the script? using UnityEngine using System.Collections public class DrawBezierHandle extends Editor public Transform startT public Transform endT function Start() startT GameObject.Find("start").GetComponent("Transform") as Transform endT GameObject.Find("end").GetComponent("Transform") as Transform function OnSceneGUI() var width float HandleUtility.GetHandleSize(Vector3.zero) 0.1 Handles.DrawBezier(startT.position, endT.position, startT.position 5 Vector.up, endT.position 5 Vector.up, Color.red, null, width)

Interpolate object collision stuck in Unity I am working on a very basic test in 2D. The problem I am having is that, when my sprite collides with the ground, it is checking the event too frequently. The sprite stays in limbo, as it doesn't have a chance to leave the ground. By the time it does, the check tells it to turn around, resulting it quickly going up and down. I uploaded an example clip to YouTube. When contact is made, the sprite needs to change it's Y axis direction. How do I fix this? Please see my code, below void Update () hitWall Physics2D.OverlapCircle(wallCheckUp.position, wallCheckRadius, whatIsWall) if (hitWall) moveUp !moveUp if (moveUp) transform.localScale new Vector3( 1f, 1f, 1f) GetComponent lt Rigidbody2D gt ().velocity new Vector2(speed, GetComponent lt Rigidbody2D gt ().velocity.x) else transform.localScale new Vector3(1f, 1f, 1f) GetComponent lt Rigidbody2D gt ().velocity new Vector2( speed, GetComponent lt Rigidbody2D gt ().velocity.x) Here is my object

Can I use Google Ads on a game published on non Google platforms? I just made a game with unity personal. And I want to publish release it on sites like Getjar, Aptoide, Slideme etc. instead of Play Store. So I want to know if I can still get revenue from Google ads or if I have to publish it on the play store to get revenue from ads.

What is the standard practice for animating motion move character or not move character? I've downloaded a bunch of (free) 3d warriors with animations. I've noticed for about 25 of them, the 'run' animation physically moves the character forward in the z direction. For the other 75 , the animation just loops with the characters feet moving etc., but does so in place, without changing the character's physical location. I could fix this by 1.) Manually updating the transform in code for this 75 , to physically move the character 2.) Alter the animation by re recording it, with a positive z value at the end (when I did this it caused the character to shift really far away the rest of the units, probably something to do with local space vs world space I haven't figured out yet). But before I go too far down this rabbit hole, I wonder if there is any kind of standard? In the general case, are 'run' 'walk' animations supposed to move the character themselves, or is it up to the coder to manually update the transform while the legs move and arms swing in place? Is one approach objectively better than the other, or maybe it depends on the use case? If so, what are the drawbacks of each? I know nothing about animation, so I don't want to break convention (if there is one).

How can I pool objects with differing properties? My game requires a 2D GameObject to be spawned every second until they fill the whole screen and the game ends (around 60 objects total). On Android I see some performance spikes whenever a GameObject is spawned, so I'd like to use object pooling to help alleviate this. However, some of my objects have random properties like a second sprite, different tag, particle effect, and so on, so I don't think it's possible to save them for object pooling. Is there any way for me to pool objects that have variable properties?

Find out triangles that are not occluded from a camera view? For a project i need to find out triangles that are directly seen by the camera user. Triangles that are occluded by other triangles should be ignored. There may be 200 thousand triangles in a model, so raycasting on a CPU is no possibility due to performance. Is there something build in to unity or opengl that can do this? If not how would you approach this problem? Many 3d editing software use techniques, e. g. to select or slice only triangles that are visible.

How can I make a look around effect of the player some kind of cutscene? I want that at some point in the game the player will be looking over the view out of the window. So I added a new Camera and positioned the camera close to the window. Then using a small script I'm turning the Camera on. But after turning the camera on I wan to make that the camera will rotate around the window area so it will give a natural feeling that the player is looking over the view outside. And the script that is attached to another GameObject that activating the Camera using System.Collections using System.Collections.Generic using UnityEngine public class ItemAction MonoBehaviour public Camera viewCamera private void Update() public void ViewCamera() viewCamera.enabled true The part I'm using is the ViewCamera method. But I messed it up. But the idea is after turning on the Camera to make it feel like looking around the view outside. How can I make the camera move first to one direction and then mirrored to the other direction ? using System.Collections using System.Collections.Generic using UnityEngine public class ItemAction MonoBehaviour public Camera viewCamera public float Speed public void ViewCamera() viewCamera.enabled true StartCoroutine(animate()) IEnumerator animate() while (transform.localEulerAngles.y gt 45) transform.Rotate(0, Time.deltaTime Speed, 0) yield return null and then possibly the same but mirrored to look in the other direction while (transform.localEulerAngles.y lt 45) transform.Rotate(0, Time.deltaTime Speed, 0) yield return null The way it is now it's just keep rotating to the same direction nonstop.

Animator, gameObject position not being kept I have idle amp popout animations. Idle simple scaling up and down 2d object and popout get the gameobject's position to the right and leave it there. I'm using animator for this purpose. I have a trigger Popout, which when triggered the animator goes from playing the Idle animation to the popout animation. Then another transition from the popout anim back to the idle anim. The problem is that when it gets back to the idle anim, the position gets back to the first one(i.e. as if the popout anim hasn't been played). My goal is, after playing the popout, the gameObject to stay at the last position from the popOut anim and to continue to be scaled up and down(the idle anim). My goal is, the gameObject to keep its last position set from the popout anim(which is to the right of its initial one) and to continue playing the idle anim from there instead of going back to its initial position. Why does the animator reverses the gameobejct's position to its initial one, after the popout anim has been played? In this video you can see the problem and what exaclty I'm doing.

most efficient way to create a grid system in unity I'm creating a little tower defence game to get myself acquainted with unity. At first I was going to emulate a grid system by capturing touches mouse clicks and rounding the coordinates to the nearest whole numbers. This is very low cost and works well for placing things, however I'm a bit of an AI geek and I've decided to make a more tangible grid so that the agents can run searches on it for pathfinding. For this I'll need a grid of nodes and for those nodes to have a bit of information attached. Would it be a much better idea to do this entirely in code? Or could I get away with placing actual cubes in a big grid on the map? This would certainly be easy as then I could ray cast against them but I've tried this and rendering that many cubes slows down the game a lot! I suppose my question is is it unnecessarily expensive to have a load of cubes set up like this, but not rendered? Or should the cost of having a load of cube shaped collision volumes be only marginally more expensive than emulating this in code? (if at all...) Also as a side question should I be able to render say, 200 cubes and have a smooth game? Am I missing some instancing options? I presumed things would be automatically instanced.

What to use if you want a looping list? No, I'm not talking about foreach. I have the following list public List lt float gt angles new List lt float gt (new float 0, 90, 180, 270 ) This list can vary depending on the object I use, having only 0 and 90 or all except 270 for example. What I want to do is have a rotClockwise and rotCounterClockwise function that grabs the value before or after a given value. Here's some pseudo code function float rotClockwise(angle) return angles.grabNextAngle(angle) function float rotCounterClockwise(angle) return angles.grabPrevAngle(angle) So calling rotClockwise(90) would return 180, rotCounterClockwise(90) would return 0, rotClockwise(270) would return 0, etc. How can I accomplish this? Is there a list type that allows me to loop back to the beginning when I reached the end?

Unity3D Lightmap bleeding in standalone build I'm running into an issue about some lightmap glitches made of black seams lines occuring only in the standalone build of our game, and it does only affect certain scenes. below is attached a screenshot of both editor and .exe build of the same scene. I'm also attaching below the current Lighting settings for that current scene, but before, our second UV Channel is not generated inside Unity3D but authored in 3DSMAX Now, even if the generated lightmaps are 4096, their texture inspector shows a max size of 2048 and no compression (tried a build with a max size of 4k with no change), i also discovered that Mip Maps are enabled by default (might be the problem ?). Above all, my build settings are Windows standalone x86, although the game is VR Only wouldn't be better to make it x86 64 only and would it solve this issue ? Current Unity Version and infos Unity 5.6.0f3 Oculus Utilities 1.14 Build settings for windows Auto graphics API Static Dynamic Batching GPU Skinning VR supported (Oculus OpenVR) MultiPass Stereo Rendering Optimize Mesh Data enabled. Mesh import infos Mesh compression off Read Write enabled Optimize Mesh Enabled Normals Import i would also state that we had a previous gearVR build (with 2048 resolution lightmaps) and this issue was never encountered Thank you.

What would be best practice for getting internal and external IP addresses for manual LAN and internet direct connections between server and client? Internal external IP addresses are needed so players can load the game, then tell their friends what their IP is to direct connect.

Once trying to open a script in Unity, it doesn't open and then I'm forced to use Task Manager to End Unity's task because can't even close it normally due to not being able to interact with the screen. No errors or warnings, VS doesn't open, can't interact with Unity anymore. This doesn't block me from working, it just isn't as convenient as before.

As you can see in the image above, the 6 dots on the back of the die are not shown, it just looks like it is empty. What can I do to fix this?

How do I flatten terrain under a game object? I've got a script that makes a terrain object and paints it with textures, but I'm having an issue. When I attempt to place game objects (such as the simple water object that unity provides), I use a Raycast to determine the correct height to place the game object, but that just ensures that it is correctly placed at that particular point. How would I go about flattening the terrain under the game object so that it doesn't go into the terrain or hang out into thin air in the case of hills?

Aim prediction along a parabola How to make a Tower Defence Mortar aim accurately I am building a very basic tower defence game in Unity3D where one tower is your standard long range mortar artillery. I want the projectile it fires to follow a parabola curve to make its movement seem like a mortar. This movement is not dependant on any physics (as I can make a projectile follow a curve but I could implement the Unity3D physics if the method used would benefit from it. My question is What technique should I use to ensure the projectile hits the locked unit whilst taking into account that the unit is moving along a possibly non linear path (defined with my A implementation.) I have not implemented any code as of yet as I wanted to consult the masses for any wisdom you can provide! My initial idea was to fix the time the projectile would take along its parabola curve (regardless of distance) and try and track the position the unit would be at after this time delay. Is this along the right lines or are there alternative methods to consider when aiming a projectile that follows a curved path instead of a linear one? Thank you for your time.

Example 01 This is coincidentally match and ok because my device screen aspect is 16 9. But here is the incorrect one (stretched) Example 02 This is 640 x 480 in resolution but it should remain in aspect ratio of 4 3. How could I keep it's aspect ratio and make it black at the extra space outside or customize it using my own image to cover the extra space ? in Android. Note I'm not talking about the canvas but entire output view.

Help is appreciated. Thanks in advance.

Generating lakes and rivers on 2D grid I recently posted a question about how to technically represent a generated terrain similar to the game kingdoms and castles. I got some great advice and decided to create a 1x1 cube at each coordinate since I will have very small maps, for now 50x50. I wrote some code to generate terrain, this is super basic atm and simply instantiates either grass or water tiles depending on the noise value at the coordinate public static class Noise public static float , GenerateNoiseMap(int mapWidth, int mapHeight, float scale) float , noiseMap new float mapWidth, mapHeight if (scale lt 0) scale .0001f for (int y 0 y lt mapHeight y ) for (int x 0 x lt mapWidth x ) float sampleX x scale float sampleY y scale float perlinValue Mathf.PerlinNoise(sampleX, sampleY) noiseMap x, y perlinValue return noiseMap public class MapGenerator MonoBehaviour public int mapWidth public int mapHeight public float noiseScale Space public GameObject grassTile, waterTile public void GenerateMap() float , noiseMap Noise.GenerateNoiseMap(mapWidth, mapHeight, noiseScale) for (int x 0 x lt mapWidth x ) for (int y 0 y lt mapHeight y ) if (noiseMap x,y gt .3) Instantiate(grassTile, new Vector3(x, 0, y), Quaternion.identity) else Instantiate(waterTile, new Vector3(x, 1, y), Quaternion.identity) It generate something like this Now this obviously does not look like a realistic landscape. My question is, how do I decide which values should represent water, and which should represent grass, in order to get a landscape that makes sense? What I would like my landmass to look like something that has lakes and maybe rivers, instead of these random puddles you see in the image above, more something like this EDIT Setting a higher scale value lead to this

Debug.Log("Writing to PlayerPrefs") PlayerPrefs.SetInt("totStars", NumOfStars) int i 0 Debug.Log("test") while (i lt NumOfStars) PlayerPrefs.SetString("starID" i, StarIDID (i) ) PlayerPrefs.SetString("starName" i, StarName (i) ) PlayerPrefs.SetString("starHIP" i, StarIDHIP (i) ) PlayerPrefs.SetString("starHD" i, StarIDHD (i) ) PlayerPrefs.SetString("starHR" i, StarIDHR (i) ) PlayerPrefs.SetString("starGL" i, StarIDGL (i) ) PlayerPrefs.SetString("starBF" i, StarIDBF (i) ) PlayerPrefs.SetString("starRA" i, StarRA (i) ) PlayerPrefs.SetString("starDec" i, StarDec (i) ) PlayerPrefs.SetString("starMag" i, StarMag (i) ) PlayerPrefs.SetString("starCI" i, StarCI (i) ) Debug.Log("star " i " complete") i PlayerPrefs.Save() i 0 int ok 0 while (i lt NumOfStars) if (PlayerPrefs.GetString("starID" i) ! null) ok i Debug.Log(ok) And this is the Debug.Log output that I am getting... As you can see, the program gets up to the First Debug Log Debug.Log("Writing to PlayerPrefs") But then stops before the Debug.Log("test") . After removing PlayerPrefs.SetInt("totStars", NumOfStars) The program gets to the Debug.Log("test") . So it is the PlayerPrefs.SetInt causing the issue. How do I fix this?

Smoothness texture map in unity I shall submit a 3d asset to the Unity asset store. Their submission guidelines say,"... must include at least an albedo,normal,metallic (or specular) and smoothness texture map." My query is how do I get the smoothness map and where do I put it ? There is just one slot by the smoothness slider where I put the metallic map. Is it really necessary to put a smoothness texture map if I already have a metallic map attached to the material? It's my first attempt to submit an asset to the asset store.

How can I make an instantiation random? I'm trying to do it so when I have an instantiated an item upon the game starting, it is random as to whether it actually instantiates or not. Here's the code I have so far public GameObject anyItem void Start() Instantiate(anyItem, new Vector3(0, 0, 0), Quaternion.identity) Instantiate(anyItem, new Vector3(11, 0, 0), Quaternion.identity) How can I do it so these items (individually, not both together) are decided randomly as to whether they will actually be instantiated or not?

How to place grass on custom terrain mesh I made a custom terrain mesh and textured it, now I want to place grass on it, but I don't know how. I only find info about grass with the unity terrain. I am not even sure what exactly to look for. What is the best easiest way to place grass on a terrain? I'd like to do it in the shader if possible, but I guess I will need additional geometry if I want it to "stick out"? (Random example picture http www.beamng.com attachments stuff png.16516 ) I'd appreciate a general outline on how to tackle this problem and maybe some links for further reading. Thanks.

Unity SkinnedMeshRender is there a way to cache mesh and restore later? In unity, I'm writing a script that deforms a mesh associated with a SkinnedMeshRenderer pretty significantly. However, at some point, I'd like to reset it back to particular states. I'd like the ability to both reset to its original position, and an intermediate position. Right now, I've tried baking the mesh Mesh originalMesh new Mesh() skinnedMeshRenderer.BakeMesh(originalMesh) But when I then try to restore it skinnedMeshRenderer.sharedMesh originalMesh It doesn't seem to behave as I would have expected. I've also tried Mesh originalMesh skinnedMeshRenderer.sharedMesh deform sharedMesh skinnedMeshRenderer originalMesh but this does nothing since it seems to be just storing a reference. Am I missing something obvious here? Just to add detail, I want to take a snapshot of all the verticies, weights, blendshapes, etc. And then restore everything back to the snapshot at a later moment in time. I can reset the blendshapes fine, but the mesh seems to be messed up.

Serialize classes in unity c Is there some best practices to serialize objects to file on mobile devices in Unity using C . I've tried to search it myself, but found only this link. However, it looks like here they are trying to cache AssetBundles. I'm new to Unity, but I have some experience in iOS (swift) development. Here we have opportunity to cache some objects(variables) in local storage, to avoid overusing network. So I wanted to create some static class (for example Storage), which caches variables to file permanently and return them by some key.

Trying to make pitch black night some meshes still dimly lit I have a directional light as a "sun". At night, I need a pitch black scene, but a mesh I'm using as terrain somehow stays faintly lit when the light intensity is 0. At night The direction light "sun" is rotated so it's beneath my world. The sun light is set to black, intensity to 0 I tried setting fog and ambient light color in RenderSettings to black I tried setting ambient intensity to 0 Notice how the background is lighter than the character. Something is causing that light to remain. However, if I enter playmode with the light object inactive, the coloring works fine.

Start timer when button pressed (what is wrong with my code?) I want a timer to start when my rocket takes off and stop when it lands. Stopping works fine (using a collider and state switching) but I can't get the timer to start when I press the boost button. Currently the timer text is displayed at the moment I pressed the button but clearly has been counting from the moment the scene started, not the moment the button is pressed. Any help will be greatly appreciated. If there is a better way to start the timer rather than when I press the boost button then I am open to ideas! Here is the all relevant code (I think). It appears as though it should be working to me, but it isn't. Timer public Text timerText private float startTime private bool started false private bool finished false void Start () startTime Time.time get time since scene started void Update () if (currentState State.Alive) ProcessBoostInput() ProcessRotationInput() ProcessFiringInput() if (started) RunTimer() private void ProcessBoostInput() if (Input.GetKey(KeyCode.A) (CrossPlatformInputManager.GetButton("Fire1"))) BoostShip() PlayBoostSound() if (started ! true) started true private void RunTimer() if (finished) return else if (started) float timeSinceTimerStart Time.time startTime string minutes ((int)timeSinceTimerStart 60).ToString() string seconds (timeSinceTimerStart 60).ToString("f3") timerText.text minutes " " seconds private void StopTimer() finished true timerText.color Color.green

Instantly snap into specific directions? In my 2d setup, I want the player to constantly move in a specific direction at a set speed. It's similar to "Snake" in that you can only move in four directions and you can't stop your movement. Right now, the way I do this is by having a char variable "direction", which can either be u, d, l, r (take a guess what those stand for). Based on those letters, I use GetComponent().MovePosition and increase decrease the position on the x or y axis. Is there a better way to do this? I would prefer if I could just enter the degree (0, 90, 180, 270) to make the player move in the right direction. I tried AddForce but I couldn't get it to work. Side note it's important for me that I can set the direction without player input, as there are some objects that force the player into a different direction. Edit As the tag would suggest, I'm looking for a Unity specific answer, as I'm not sure which function would best suit my needs.

Plugins for creating and styling custom Editor Windows like C C Form Designer or Web Inspector ? Unity3d allows to construct window with custom UI. Just need to use EditorGUI EditorGUILayout classes and their static methods. Example of custom window The problem is that all the components have to be added manually via script. Then need to save, switch to Editor, wait for little compile things, and then we can see the result. In web development people use Web Inspector (for example, we can press F12 in chrome, Tab Elements Styles). We can add all needed properties to element and can see the result in real time. EDIT. another example (better than previous) we know C winFormApp, C MFC e.t.c, which has form designer. We can choose any elements and set their properties It would be nice to have similar plugins for Unity So. Does Unity3d have similar tools, utilities, plugins? Utilities to inspect code and editing styles (position, margin, padding, background, width, height, color e.t.c.)?

Movement nudge instead of constant I am making a small game where the player is constantly moving upwards, and I am having slight problems with the movement to the sides. The script located under works quite perfectly in itself, but my problem is that I want the balloon player to nudge in a direction, rather than go at a constant speed. Kinda like a small punch to the side of the balloon. How could I easily implement this? GetMouseButton or GetMouseButtonDown? Thanks in advance. ) void Update () transform.Translate(Vector3.up Time.deltaTime, Space.World) if(Input.GetMouseButton(0)) transform.Translate(Vector3.left Time.deltaTime, Space.World) if(Input.GetMouseButton(1)) transform.Translate(Vector3.right Time.deltaTime, Space.World)

Best practice for toggling between ragdoll and CharacterController One feature of the game I'm working on is that if a character is hit with a certain amount of force, it will temporarily ragdoll, then get up off the ground after a small period of time. This character is moved by a CharacterController (CC) component. At the moment, I have the model as a child of an object with a CC component and movement script. My issue is that when the ragdoll is activated animator is disabled, the model moves independently of the CC if it ragdolls with some arbitrary force in any direction, the CC does not move with it (as you'd expect). This would be fine if the ragdoll wasn't meant to be re enabled, but it is. At this stage, the model teleports moves to where the CC is, and it looks very weird. I have tried a few different methods to synchronize the two Decoupling the CC and model. Both objects are children of a shared parent, and I added them both to an PhysicsIgnoreLayer (for now eventually if I go with this I'll probably add all the ragdoll colliders to an array and ignore them individually). When the ragdoll state is enabled in the parent, the CC is disabled and the object is teleported to the root bone every frame. When the CC is enabled, the model is teleported to the CC object every frame. See here. The issue here is that setting the position means extra Update() calls and it lags behind the controller a little. Also, because the model isn't a child of the controller, it doesn't inherit the velocity of the controller, so it needs to be manually applied. Changing the parented GameObject at runtime. Depending on the state of the character, the CC model will be parented to each other if the CC is active, the model is set as its child and vice versa using SetParent. I couldn't get this one working (the local position variable was a little confusing to me, but no configuration I tried worked for me). Conjoined CC and model. I placed the CC on the same object as the model. This isn't really ideal for me because I want greater control over the rotation and presentation of the model. I couldn't get this one working either I don't know how I could set the position of the CC without moving the whole thing. Is there a more effective way of doing this? If so, what? I feel like I am greatly overcomplicating this. Any help would be great. In an ideal situation, I could have the model as a child of the controller (or behave that way) and move the CC when it is inactive without affecting the model position.

Find centre of rotation from two locations Ultimately I need to get c from the image and have a, b and that it takes 90 degrees to get a to d. My solution to this was to rotate a around to get to d by the rotation. Then use the Y value from a and X from d to get c. So far I an having trouble getting the rotation of a to d to work properly, what am I doing wrong in the rotation? Vector3 d (Quaternion.Euler(0f, 0f, rotation) (a b)) b

Move parent according to child axis in Unity? Can I ask my parent to move according to the child axis? This means if I turn right, then right again, the parent has to be at 180 from its original position, and not only at 90 (because "Right" would mean "stay on the right axis from the parent axis", and what I want is "move the parent according to the child axis"). The parent has a script to move, and the child has the script to rotate, so I would need to use the new rotation from the child, and not the rotation from the parent. My attempt so far is this one in "MoveBody()", oldTr transform.position works without a bug, but it is using the parent axis. With oldTr this objW , there is a bug, the parent goes somewhere in the scene and move its "z" axis in an odd way this obj GameObject.Find("this obj").transform the child to rotate this objW this obj.TransformDirection(this obj.forward) world ... MoveBody( new Vector3( 3.0f, 0, 0 ) ) ... private void MoveBody( Vector3 vec ) Debug.Log("transform.position " transform.position " this objW " this objW) same value here Vector3(0,0,1) oldTr this objW transform.position newTr this objW transform.position newTr vec transform.position Vector3.MoveTowards(oldTr, newTr, sideSpeed Time.deltaTime) Is it possible to do it this way? Or should I translate each axis by hand? Thanks

Multiple cameras using a single skybox with same perspective I am using the enviro package for weather and to have a moving sun in the background. I'm building an installation with 3 screens and I want to have the sun track across the screens. However what I end up with is 3 separate skyboxes and 3 suns, one on each screen. Is there a way I can have the cameras share a single skybox?

How do I add a Rigid body and a box collider component to a Texture2D? I am making a snake game. I'm basing it on a basic tutorial game, which does no collision detection, wall checking or different levels. All snake head, piece, food, even the background is made of Texture2D. I want the head of the snake to detects 2D collisions with them, but Rect.contains isn't working. I'd prefer to detect collisions by onTriggerEnter() for which I need to add BoxCollider to my snakeHead.

Isn't OnGUI and Event cyclical? Here's what I don't understand about Events the documentation says that Events correspond to user input (key presses, mouse actions), or are UnityGUI layout or rendering events. For each event OnGUI is called in the scripts so OnGUI is potentially called multiple times per frame. Event.current corresponds to "current" event inside OnGUI call. the documentation pertaining to onGUI states that it hasone call per event That doesn't make sense to me, because I know I can call Events within OnGUI. I have an OnGUI function that draws a grid using x and y nested for loops, then checks using Event.current.mousePosition if your mouse is hovering over a grid block. What I don't get is how OnGUI is ever called, if OnGUI is only called when an event occurs, but I have the event inside OnGUI so how can you ever check if the event is being called inside a script that is only called after the event is called? I know that probably sounds confusing I'm just puzzled by the seemingly cyclical nature of ongui.

UI Button Not Working On Animation I have hit a problem with my player, I have been following a tutorial on building a platformer.

How can the player open this door and have its collision physics stay in sync? I just finished modeling a scene in Blender like this Now I'm animating and creating interactions between the player and the objects inside the house. When I reached the doors, I started having doubts. Originally, I created the doors animations using Blend Shapes to easly control the transition between the open close states and to allow the door being half opened or closed. (That's because my interaction system allows to interact partially with object, like for example the door system at Amnesia The Dark descent outlast) The trouble is, that the collider of the doors doesn't update when the Blendshapes values changes. How can the player open this door and have its collision physics stay in sync

Errors when baking lights in unity3d So, i'm developing a game in unity and avoided baking lightmaps untill now ( i just assembled my new workstation setup wich is capable of baking the lightmaps and not the computer ). And now i have opened my project, imported it nicely and all, went to the lightning tab and clicked generate lightning ( naturallly i had auto bake disabled). And everytime i do that i get a billion errors, and they do not stop popping up even after i force stop amp cancel, i have to clear baking data in order to do anything ( of course unity is laggy as hell when it's spitting out these errors ). I even tried just a simple scene with just a plane on it. It's the same. I checked and it works fine on another empty project, wich lead me to the conclusion that some texture in my assets folder is causing the error even though it's not on the scene at all. In this case i'm kina doomed, i have absolutely 0 idea wich texture could this be ( i have quite a lot of them) and why would it even cause problems. Any way to check that? Or maybe does somebody know another possible reason for this problem? I tried to do research but found literally nothing. No thread about the issue, nothing. Not even the same errors. Thanks in advance. PS i have baked amp realtime GI disabled

Making my characters modular I'm making a school based sandbox adventure game in Unity. I need a lot of NPCs with different apperances. I dreaded this since I don't have fun doing art and it is usually the reason I end up becoming burnt out of projects. My solution for this was to segregate parts of the characters by color. The skin being green, hair being blue, shirt being red and trousers leg wear being yellow. Then, I would use a shader to change these colors to something else. The result is this sprite sheet and the ability to easily change the apperance of my NPCs to make them look different from eachother but there's still an issue. A lot of the characters have the same hair style etc. Not to mention when I make a new hair style for a female, I have to then draw that style 3 4 more times for the different combinations of clothes. The solution for this that would work ideally would be a modular apporach. I would only need to draw the sprite once and just swap out different clothing combinations. I have attempted this before but the main issue that kept on coming up was the different sprites not lining up, especially when changing the different sprites. The art style is pixel art so they have to line up perfectly to look nice. How should I go about doing this to ensure I can fit every sprite together perfectly, no matter the combinations I choose?
