# Person-Chat Minigame Design

## Overview
A cinematic conversation interface that shows zoomed character portraits during face-to-face dialogue with in-person NPCs. Similar to phone-chat but with visual emphasis on the characters speaking.

## Visual Design Philosophy

### Cinematic Presentation
- **Large character portraits**: 4x zoomed sprites showing character faces
- **Side-by-side layout**: NPC on left, player on right
- **Subtitle-style dialogue**: Text overlays the portrait area or appears below
- **Minimal UI chrome**: Focus on characters and conversation
- **Pixel-art aesthetic**: Maintain sharp edges, no border-radius, 2px borders

### Differences from Phone-Chat
| Aspect | Phone-Chat | Person-Chat |
|--------|-----------|-------------|
| Context | Remote messaging | Face-to-face |
| Visuals | Phone UI with avatar icons | Zoomed sprite portraits |
| Layout | Single column messages | Side-by-side characters |
| Atmosphere | Asynchronous | Immediate/present |
| Contact list | Multiple contacts | Single conversation |

### Layout Zones
1. **Header** (60px): Title and close button
2. **Portrait Area** (300px): Character faces side-by-side
3. **Dialogue Area** (150px): Text box showing current speech
4. **Choices Area** (flexible): Choice buttons stacked
5. **Footer** (60px): Notebook and close buttons

## Portrait Rendering System

### Approach: Canvas Screenshot of Game Viewport (SIMPLIFIED)

**Strategy:**
- Capture current game canvas when conversation starts
- Scale and zoom on specific sprite positions
- Use CSS transform for visual zoom effect
- Simple, performant, no complex texture management

**Pros:**
- Minimal code complexity
- Reuses existing game rendering
- Works with any sprite instantly
- No special texture management
- Easy to zoom in with CSS transform

**Cons:**
- Static portrait (doesn't update with animations during conversation)
- Need to center on sprite when zooming

**Implementation:**
```javascript
class SpritePortrait {
    constructor(gameCanvas, sprite, scale = 4) {
        this.gameCanvas = gameCanvas;
        this.sprite = sprite;
        this.scale = scale; // Zoom level (4x)
    }
    
    captureAsDataURL() {
        // Get canvas image data
        return this.gameCanvas.toDataURL();
    }
    
    getZoomViewBox() {
        // Calculate viewport to show zoomed sprite
        const spriteX = this.sprite.x;
        const spriteY = this.sprite.y;
        
        // At 4x zoom, we want 256x256 area centered on sprite
        // Original area before zoom: 64x64
        const viewWidth = 256 / this.scale;  // 64
        const viewHeight = 256 / this.scale; // 64
        
        return {
            x: spriteX - viewWidth / 2,
            y: spriteY - viewHeight / 2,
            width: viewWidth,
            height: viewHeight,
            scale: this.scale
        };
    }
}
```

**CSS Zoom Effect:**
```css
.person-chat-portrait-canvas {
    width: 256px;
    height: 256px;
    image-rendering: pixelated;
    object-fit: cover;
    object-position: center;
}
```

### Why This Works
1. **Simplicity**: One screenshot, scale via CSS
2. **Reuses game rendering**: No duplicate rendering
3. **Pixel-perfect**: Maintains game's pixel art style
4. **Performance**: Single capture, CSS transform is GPU accelerated
5. **Flexibility**: Works with any sprite, any animation state

## CSS Styling

### File: css/person-chat-minigame.css
```css
/* Person-Chat Minigame Styles */

.person-chat-container {
    display: flex;
    flex-direction: column;
    gap: 20px;
    padding: 20px;
    max-width: 900px;
    margin: 0 auto;
}

/* Portraits Section */
.person-chat-portraits {
    display: flex;
    justify-content: space-around;
    gap: 40px;
    padding: 20px;
}

.portrait-wrapper {
    display: flex;
    flex-direction: column;
    align-items: center;
    gap: 10px;
}

.portrait-wrapper canvas {
    width: 256px;
    height: 256px;
    border: 2px solid #000;
    image-rendering: pixelated;
    image-rendering: crisp-edges;
}

.portrait-label {
    font-size: 18px;
    font-weight: bold;
    text-align: center;
}

/* Dialogue Section */
.person-chat-dialogue {
    background-color: #f0f0f0;
    border: 2px solid #000;
    padding: 20px;
    min-height: 100px;
}

.dialogue-text {
    font-size: 16px;
    line-height: 1.5;
    white-space: pre-wrap;
}

/* Choices Section */
.person-chat-choices {
    display: flex;
    flex-direction: column;
    gap: 10px;
}

.person-chat-choice {
    background-color: #fff;
    border: 2px solid #000;
    padding: 15px;
    font-size: 16px;
    text-align: left;
    cursor: pointer;
    transition: background-color 0.2s;
}

.person-chat-choice:hover {
    background-color: #e0e0e0;
}

.person-chat-choice:active {
    background-color: #d0d0d0;
}
```

## Integration with Interaction System

### Triggering Person-Chat
```javascript
// In js/systems/interactions.js

function handleNPCInteraction(npc) {
    console.log('💬 Starting conversation with', npc.displayName);
    
    // Start person-chat minigame
    window.MinigameFramework.startMinigame('person-chat', {
        npcId: npc.id,
        npcName: npc.displayName,
        title: `Talking to ${npc.displayName}`,
        onComplete: (result) => {
            console.log('Conversation complete:', result);
            
            // Emit event
            if (window.eventDispatcher) {
                window.eventDispatcher.emit('npc_conversation_ended', {
                    npcId: npc.id,
                    npcName: npc.displayName
                });
            }
        }
    });
}
```

## Animation Synchronization

### During Conversation
- **NPC speaking**: Show NPC's current animation frame in portrait
- **Player choosing**: Subtle highlight on player portrait
- **Action performed**: Brief flash or effect on relevant portrait

### Update Timing
```javascript
// In person-chat-minigame.js update loop

update() {
    // Update portraits to match current sprite frames
    if (this.portraits) {
        this.portraits.update();
        this.ui.updatePortraitCanvases();
    }
}
```

## Next Steps
1. Implement PersonChatMinigame class
2. Create portrait rendering system
3. Style UI with person-chat-minigame.css
4. Integrate with interaction system
5. Test with sample NPC
