## 🚀 Usage

### 1. Access the UI
Navigate to: `http://localhost:3000/goals/ui`

### 2. Create a Goal
1. Click "Create New Goal"
2. Configure:
   - **Name**: Display name for the goal
   - **Type**: Coin, Likes, Follower, or Custom
   - **Template**: Choose from 6 templates
   - **Start/Target Values**: Set initial and goal values
   - **Animations**: Select update and reach animations
   - **On Reach Behavior**: What happens when goal is reached
   - **Overlay Size**: Width and height in pixels

3. Click "Save Goal"

### 3. Add to OBS
1. Copy the overlay URL from the goal card
2. In OBS, add a new "Browser Source"
3. Paste the URL: `http://localhost:3000/goals/overlay?id={goalId}`
4. Set width/height to match your goal's overlay size
5. Position anywhere on your scene

### 4. Multiple Goals
- Create as many goals as you want
- Each gets its own overlay URL
- Position each independently in OBS
- All update in real-time

## 🔧 API Endpoints

## 📡 WebSocket Events

### Client → Server
```javascript
socket.emit('goals:subscribe', goalId);         // Subscribe to goal
socket.emit('goals:unsubscribe', goalId);       // Unsubscribe
socket.emit('goals:get-all');                   // Get all goals
socket.emit('goals:animation-end', data);       // Signal animation complete
```

### Server → Client
```javascript
socket.on('goals:all', data);                   // All goals
socket.on('goals:created', data);               // Goal created
socket.on('goals:updated', data);               // Goal updated
socket.on('goals:deleted', data);               // Goal deleted
socket.on('goals:value-changed', data);         // Value changed
socket.on('goals:reached', data);               // Goal reached
socket.on('goals:reset', data);                 // Goal reset
socket.on('goals:config-changed', data);        // Config changed
```

## 🎯 Goal Types

### Coin Goal
Tracks gift coins from TikTok viewers. Automatically increments when gifts are received.

### Likes Goal
Tracks stream likes. Automatically increments when viewers like the stream.

### Follower Goal
Tracks new followers. Automatically increments when someone follows.

### Custom Goal
Manually controlled. Use the UI or Flow actions to update.

## 🎨 Customization

### Theme Colors
Each goal supports custom theming via the `theme_json` field:
```json
{
  "primaryColor": "#60a5fa",
  "secondaryColor": "#3b82f6",
  "textColor": "#ffffff",
  "bgColor": "rgba(15, 23, 42, 0.95)"
}
```

### Overlay Size
Set custom width/height for each goal to fit your layout perfectly.

## 🔄 State Machine

Each goal has its own state machine with these states:

- **IDLE** - Waiting for events
- **UPDATING** - Value is being updated
- **ANIMATING_UPDATE** - Update animation playing
- **REACHED** - Goal reached target
- **ANIMATING_REACH** - Reach animation playing
- **PROCESSING_REACH** - Applying reach behavior
- **HIDDEN** - Goal is hidden

Transitions are automatic and managed internally.

## 🎬 Flow Integration

Use Flow actions to control goals:

```javascript
// Set goal value
await flowAction('goals.set_value', { goalId: 'abc123', value: 500 });

// Increment goal
await flowAction('goals.increment', { goalId: 'abc123', amount: 10 });

// Reset goal
await flowAction('goals.reset', { goalId: 'abc123' });

// Toggle enabled
await flowAction('goals.toggle', { goalId: 'abc123' });
```
