# PWA UI Enhancement - Profile, Inventory & Interactables

## Summary
Enhanced the PWA game interface with three major improvements:
1. **Profile Sidebar** - Complete character stats display
2. **Inventory System** - Visual grid with item display
3. **Interactable Images** - Large image display for interactables

## Changes Made

### 1. Profile Sidebar (Right Sidebar)
**File: `pwa/src/components/Game.tsx`**
- Replaced simple inventory placeholder with comprehensive profile section
- Added health and stamina progress bars (moved from header to sidebar)
- Display character information:
  - Level and XP
  - Unspent stat points (highlighted if available)
  - Attributes: Strength, Agility, Endurance, Intellect
- Clean, compact layout matching Telegram bot style

**File: `pwa/src/components/Game.css`**
- Added `.profile-sidebar` styles with dark background and red border
- Created `.sidebar-stat-bars` with progress bar animations

- Stamina bar: Yellow gradient (#ffc107 → #ffeb3b) with glow
- Stats displayed in compact rows with labels and values
- Unspent points highlighted with yellow background and pulse animation
- Added divider between XP info and attributes

### 2. Inventory System (Right Sidebar)
**File: `pwa/src/components/Game.tsx`**
- Implemented inventory grid displaying items from `playerState.inventory`
- Each item shows:
  - Image (if available) or fallback icon (📦)
  - Quantity badge (if > 1) in bottom-right corner
  - Equipped indicator ("E" badge) in top-left corner
- Empty state: Shows "Empty" message
- Items are clickable with hover effects

**File: `pwa/src/components/Game.css`**
- Added `.inventory-sidebar` with blue border theme (#6bb9f0)
- Created responsive grid: `repeat(auto-fill, minmax(60px, 1fr))`
- Item cards: 60x60px with aspect-ratio 1:1
- Hover effect: Scale 1.05, blue glow, border highlight
- Quantity badge: Yellow text (#ffc107) on dark background
- Equipped badge: Red background (#ff6b6b) with "E" indicator
- Image sizing: 80% of container with object-fit: contain

### 3. Interactable Images (Left Sidebar)
**File: `pwa/src/components/Game.tsx`**
- Restructured interactable display to show images
- Layout:
  - Image container: 200px height, full-width
  - Content section: Name and action buttons
- Images load from `interactable.image_path`
- Fallback: Hide image if load fails
- Image zoom effect on hover

**File: `pwa/src/components/Game.css`**
- Created `.interactable-card` replacing old `.interactable-item`
- Image container: 200px height, centered, cover fit
- Hover effects:
  - Border color intensifies
  - Yellow glow shadow
  - Card lifts (-2px translateY)
  - Image scales to 1.05
- Smooth transitions on all effects
- Maintained yellow theme (#ffc107) for consistency

## Visual Improvements

- **Stamina**: Yellow gradient with glow (#ffc107 → #ffeb3b)
- **Profile**: Red borders (rgba(255, 107, 107, 0.3))
- **Inventory**: Blue borders (#6bb9f0)
- **Interactables**: Yellow borders (#ffc107)

### Animations
- Progress bar width transitions (0.3s ease)
- Hover effects: transform, box-shadow, scale
- Unspent points: Pulse animation (2s infinite)
- Image zoom on card hover

### Layout
- Right sidebar divided into two sections:
  1. Profile (top) - Character stats
  2. Inventory (bottom) - Item grid
- Left sidebar: Interactables with large images
- All sections have consistent rounded corners and dark backgrounds

## Data Flow

### Profile Data
```typescript
Profile {
  name: string
  level: number
  xp: number
  hp: number
  max_hp: number
  stamina: number
  max_stamina: number
  strength: number
  agility: number
  endurance: number
  intellect: number
  unspent_points: number
  is_dead: boolean
}
```

### Inventory Data
```typescript
PlayerState {
  inventory: Array<{
    name: string
    quantity: number
    image_path?: string
    description?: string
    is_equipped?: boolean
  }>
}
```

### Interactable Data
```typescript
Location {
  interactables: Array<{
    instance_id: string
    name: string
    image_path?: string
    actions: Array<{
      id: string
      name: string
      description: string
    }>
  }>
}
```

## API Endpoints Used
- `GET /api/game/state` - Player state with inventory
- `GET /api/game/profile` - Character profile with stats
- `GET /api/game/location` - Current location with interactables

## Browser Compatibility
- CSS Grid for responsive layouts
- Flexbox for alignments
- Modern CSS properties (aspect-ratio, object-fit)
- Smooth transitions and animations
- Works in all modern browsers (Chrome, Firefox, Safari, Edge)

## Future Enhancements
- Item interaction (Equip, Use, Drop buttons)
- Inventory sorting and filtering
- Item tooltips with detailed descriptions
- Drag-and-drop for item management
- Carry weight/volume display with progress bars
- Stat point allocation interface

## Testing
1. Profile displays correctly with all stats
2. Inventory grid shows items with images
3. Equipped items show "E" badge
4. Item quantities display correctly
5. Interactables show images (200px height)
