+ # Pictuary Battle Engine
2
+
3
+ A standalone, testable battle system for the Pictuary game, implementing the battle mechanics defined in `battle_system_design.md`.
4
+
5
+ ## Overview
6
+
7
+ This battle engine provides a complete turn-based combat system implementing EVERYTHING from `battle_system_design.md`:
8
+
9
+ - **Type effectiveness** based on Pictuary's photography-themed types (Beast, Bug, Aquatic, Flora, Mineral, Space, Machina, Structure, Culture, Cuisine)
10
+ - **Composable effects system** with 10 different effect types
11
+ - **Advanced damage formulas** (standard, recoil, drain, fixed, percentage)
12
+ - **Mechanic override system** for special abilities that modify core game mechanics
13
+ - **Trigger-based special abilities** with 18 different trigger events
14
+ - **Status effects** with chance-based application and turn-end processing
15
+ - **Field effects** with stackable/non-stackable variants
16
+ - **PP manipulation** system (drain, restore, disable)
17
+ - **Counter moves** and priority modification
18
+ - **Conditional effects** with 25+ different conditions
19
+ - **Extreme risk-reward moves** as defined in the design document
20
+ - **Comprehensive test coverage** (116 tests across 7 test files)
21
+
22
+ ## Architecture
23
+
24
+ ### Core Components
25
+
26
+ - **`BattleEngine.ts`** - Main battle orchestration and logic
27
+ - **`types.ts`** - Type definitions for all battle system interfaces
28
+ - **`test-data.ts`** - Example Piclets and moves for testing
29
+ - **`*.test.ts`** - Comprehensive test suites
30
+
31
+ ### Key Features
32
+
33
+ 1. **Battle State Management**
34
+ - Turn-based execution with proper phase handling
35
+ - Action priority system (priority → speed → random)
36
+ - Win condition checking and battle end logic
37
+ - Field effects tracking and processing
38
+
39
+ 2. **Advanced Damage System**
40
+ - **Standard damage**: Traditional attack vs defense calculation with type effectiveness and STAB
41
+ - **Recoil damage**: Self-harm after dealing damage (e.g., 25% recoil)
42
+ - **Drain damage**: Heal user for portion of damage dealt (e.g., 50% drain)
43
+ - **Fixed damage**: Exact damage amounts regardless of stats
44
+ - **Percentage damage**: Damage based on target's max HP percentage
45
+ - Type effectiveness calculations with dual-type support
46
+ - STAB (Same Type Attack Bonus)
47
+ - Accuracy checks with move-specific accuracy values
48
+
49
+ 3. **Comprehensive Effect System**
50
+ - **damage**: 5 different damage formulas with conditional scaling
51
+ - **modifyStats**: Stat changes (increase/decrease/greatly_increase/greatly_decrease)
52
+ - **applyStatus**: Status effects with configurable chance percentages
53
+ - **heal**: Healing with amounts (small/medium/large/full) or percentage/fixed formulas
54
+ - **manipulatePP**: PP drain, restore, or disable targeting specific moves
55
+ - **fieldEffect**: Battlefield modifications affecting all combatants
56
+ - **counter**: Delayed damage reflection based on incoming attack types
57
+ - **priority**: Dynamic priority modification for moves
58
+ - **removeStatus**: Cure specific status conditions
59
+ - **mechanicOverride**: Fundamental game mechanic modifications
60
+
61
+ 4. **Status Effects**
62
+ - **Poison/Burn**: Turn-end damage (1/8 max HP)
63
+ - **Paralysis/Sleep/Freeze**: Action prevention
64
+ - **Confusion**: Self-targeting chance
65
+ - **Chance-based application**: Configurable success rates (e.g., 30% freeze chance)
66
+ - **Status immunity**: Abilities can grant immunity to specific statuses
67
+ - **Status removal**: Moves and abilities can cure conditions
68
+
69
+ 5. **Special Ability System**
70
+ - **18 Trigger Events**: onDamageTaken, onSwitchIn, endOfTurn, onLowHP, etc.
71
+ - **Conditional triggers**: Abilities activate based on HP thresholds, weather, status
72
+ - **Multiple effects per trigger**: Complex abilities with layered effects
73
+ - **Mechanic overrides**: Abilities that fundamentally change game rules
74
+
75
+ 6. **Field Effects**
76
+ - **Global effects**: Affect entire battlefield
77
+ - **Side effects**: Affect one player's side only
78
+ - **Stackable/Non-stackable**: Configurable effect layering
79
+ - **Duration tracking**: Effects expire after set number of turns
80
+
81
+ 7. **Move Flags System**
82
+ - **Combat flags**: contact, bite, punch, sound, explosive, draining, ground
83
+ - **Priority flags**: priority, lowPriority
84
+ - **Mechanic flags**: charging, recharge, multiHit, twoTurn, sacrifice, gambling
85
+ - **Interaction flags**: reflectable, snatchable, copyable, protectable, bypassProtect
86

87
+
88
+ ## Usage
89
+
90
+ ### Basic Battle Setup
91
+
92
+ ```typescript
93
+ import { BattleEngine } from './BattleEngine';
94
+ import { STELLAR_WOLF, TOXIC_CRAWLER } from './test-data';
95
+
96
+ // Create a new battle
97
+ const battle = new BattleEngine(STELLAR_WOLF, TOXIC_CRAWLER);
98
+
99
+ // Execute a turn
100
+ const playerAction = { type: 'move', piclet: 'player', moveIndex: 0 };
101
+ const opponentAction = { type: 'move', piclet: 'opponent', moveIndex: 1 };
102
+
103
+ battle.executeActions(playerAction, opponentAction);
104
+
105
+ // Check battle state
106
+ console.log(battle.getState());
107
+ console.log(battle.getLog());
108
+ console.log(battle.isGameOver(), battle.getWinner());
109
+ ```
110
+
111
+ ### Creating Custom Piclets
112
+
113
+ ```typescript
114
+ import { PicletDefinition, Move, PicletType, AttackType } from './types';
115
+
116
+ const customMove: Move = {
117
+ name: "Thunder Strike",
118
+ type: AttackType.SPACE,
119
+ power: 80,
120
+ accuracy: 90,
121
+ pp: 10,
122
+ priority: 0,
123
+ flags: ['explosive'],
124
+ effects: [
125
+ {
126
+ type: 'damage',
127
+ target: 'opponent',
128
+ amount: 'strong'
129
+ },
130
+ {
131
+ type: 'applyStatus',
132
+ target: 'opponent',
133
+ status: 'paralyze',
134
+ condition: 'ifLucky50'
135
+ }
136
+ ]
137
+ };
138
+
139
+ const customPiclet: PicletDefinition = {
140
+ name: "Storm Guardian",
141
+ description: "A cosmic entity that commands lightning",
142
+ tier: 'high',
143
+ primaryType: PicletType.SPACE,
144
+ baseStats: { hp: 120, attack: 100, defense: 90, speed: 85 },
145
+ nature: "Bold",
146
+ specialAbility: {
147
+ name: "Lightning Rod",
148
+ description: "Draws electric attacks and boosts power"
149
+ },
150
+ movepool: [customMove, /* other moves */]
151
+ };
152
+ ```
153
+
154
+ ## Testing
155
+
156
+ The battle engine includes comprehensive test coverage:
157
+
158
+ ```bash
159
+ # Run all battle engine tests

+ npm test src/lib/battle-engine/
161
+
162
+ # Run specific test file
163
+ npm test src/lib/battle-engine/BattleEngine.test.ts
164
+
165
+ # Run with UI
166
+ npm run test:ui
167
+ ```
168
+
169
+ ### Test Categories
170
+
171
+ - **Unit Tests** (`BattleEngine.test.ts`)
172
+ - Battle initialization
173
+ - Basic battle flow
174
+ - Damage calculations
175

184
+ - Complete battle scenarios
185
+ - Multi-turn battles with complex interactions
186
+ - Performance and stability tests
187
+ - Edge cases
188
+
189
+ ## Design Principles
190
+
191
+ Following the battle system design document:
192
+
193
+ 1. **Simple JSON Schema** - Moves are defined with conceptual effect levels (weak/normal/strong/extreme) rather than specific numeric values
194
+ 2. **Composable Effects** - Multiple effects per move with conditional triggers
195
+ 3. **Bold and Dramatic** - Effects can be powerful with interesting tradeoffs
196
+ 4. **Type-Driven** - Photography-themed types with meaningful interactions
197
+ 5. **Special Abilities** - Passive traits that transform gameplay
198
+
199
+ ## Integration with Main App
200
+
201
+ This module is designed to be eventually imported into the main Svelte app:
202
+
203
+ ```typescript
204
+ // In Battle.svelte
205
+ import { BattleEngine } from '$lib/battle-engine/BattleEngine';
206
+ import type { PicletDefinition } from '$lib/battle-engine/types';
207
+
208
+ // Convert PicletInstance to PicletDefinition format
209
+ // Initialize battle engine
210
+ // Replace existing battle logic
211
+ ```
212
+
213
+ ## Future Enhancements
214
+
215
+ Planned features following the design document:
216
+
217
+ - [ ] Special ability trigger system
218
+ - [ ] Field effects and weather
219
+ - [ ] Counter moves and priority manipulation
220
+ - [ ] PP manipulation effects
221
+ - [ ] Multi-target moves
222
+ - [ ] Switch actions and party management
223
+ - [ ] Critical hit calculations
224
+ - [ ] More complex conditional effects
225
+ - [ ] Battle replay system
226
+
227
+ ## Performance Notes
228
+
229
+ - Battle state is immutable (deep-cloned on `getState()`)
230
+ - Efficient type effectiveness lookup using enums
231
+ - Minimal memory allocation during battle execution
232
