## ✅ COMPLETED WORK
|
||||
|
||||
### Phase 1: Foundation ✅
|
||||
- [x] Created `types.ts` with all TypeScript interfaces
|
||||
- [x] Created `hooks/` directory structure
|
||||
- [x] Created `useGameEngine.ts` skeleton with state management
|
||||
- [x] Extracted `MovementControls.tsx` component
|
||||
|
||||
### Phase 2: UI Components ✅
|
||||
- [x] Extracted `CombatView.tsx` (PvP and PvE combat)
|
||||
- [x] Extracted `LocationView.tsx` (enemies, items, NPCs, corpses, other players)
|
||||
- [x] Extracted `PlayerSidebar.tsx` (stats, equipment, inventory)
|
||||
- [x] Extracted `Workbench.tsx` (craft, repair, salvage tabs)
|
||||
|
||||
### Phase 3: Logic Implementation ✅
|
||||
- [x] Implemented all 19 handler functions in `useGameEngine.ts`:
|
||||
- ✅ Item handlers (use, equip, unequip, drop, pickup)
|
||||
- ✅ Crafting handlers (craft, repair, uncraft, switch tabs)
|
||||
- ✅ Combat handlers (initiate, action, flee, exit)
|
||||
- ✅ PvP handlers (initiate, action, acknowledge, exit)
|
||||
- ✅ Interaction handlers (interact, loot corpse, view corpse)
|
||||
- ✅ Stat handler (spend points)
|
||||
|
||||
### Phase 4: Integration ✅
|
||||
- [x] Created minimal `Game.tsx` orchestrator
|
||||
- [x] Wired up all component props
|
||||
- [x] Connected `useGameEngine` hook
|
||||
- [x] Preserved WebSocket handling
|
||||
- [x] Backed up original to `Game_OLD_BACKUP.tsx`

## 🎯 BENEFITS ACHIEVED
|
||||
|
||||
### 1. **Modularity** ✅
|
||||
- Each component has a single responsibility
|
||||
- Clear separation of concerns (UI vs Logic vs Types)
|
||||
|
||||
### 2. **Maintainability** ✅
|
||||
- Easy to locate specific functionality
|
||||
- Bugs can be isolated to specific components
|
||||
- Changes don't ripple across the entire codebase
|
||||
|
||||
### 3. **Readability** ✅
|
||||
- Game.tsx is now ~350 lines (simple orchestration)
|
||||
- Each component is focused and understandable
|
||||
- Clear prop interfaces document data flow
|
||||
|
||||
### 4. **Reusability** ✅
|
||||
- Components can be used independently
|
||||
- useGameEngine hook can be shared across features
|
||||
- Types are centralized in one file
|
||||
|
||||
### 5. **Type Safety** ✅
|
||||
- Strong TypeScript interfaces for all props
|
||||
- GameEngineState and GameEngineActions interfaces
|
||||
- Compile-time error detection
|
||||
|
||||
### 6. **Testability** ✅
|
||||
- Components can be tested in isolation
|
||||
- Hook logic can be unit tested
|
||||
- Mock data can be easily injected
|
||||
|
||||
### 7. **Performance** ✅
|
||||
- Smaller component re-renders
|
||||
- Optimized with useCallback hooks
|
||||
- Efficient state updates
|
||||
|
||||
### 8. **Scalability** ✅
|
||||
- Easy to add new components
|
||||
- Easy to extend existing components
|
||||
- Clear patterns for future development

## 📝 KEY PATTERNS
|
||||
|
||||
### State Management Pattern
|
||||
```typescript
|
||||
const [state, actions] = useGameEngine(token, handleWebSocketMessage)
|
||||
|
||||
// state: GameEngineState (all game state)
|
||||
// actions: GameEngineActions (all handlers)
|
||||
```
|
||||
|
||||
### Component Props Pattern
|
||||
```typescript
|
||||
interface ComponentProps {
|
||||
// State props (read-only)
|
||||
location: Location
|
||||
profile: Profile | null
|
||||
combatState: CombatState | null
|
||||
|
||||
// Action props (event handlers)
|
||||
onMove: (direction: string) => void
|
||||
onCombat: (action: string) => void
|
||||
}
|
||||
```
|
||||
|
||||
### Handler Implementation Pattern
|
||||
```typescript
|
||||
const handleAction = async () => {
|
||||
try {
|
||||
setMessage('Processing...')
|
||||
const response = await api.post('/api/endpoint', data)
|
||||
setMessage(response.data.message)
|
||||
await fetchGameData() // Refresh state
|
||||
} catch (error: any) {
|
||||
setMessage(error.response?.data?.detail || 'Action failed')
|
||||
}
|
||||
}
|
||||
```
