|
**Goal:** Implement sophisticated voice interactions that respect guild boundaries and manage ephemeral resources.
|
|
|
|
## 1. Resource Scoping Strategy
|
|
|
|
Voice features **MUST** be scoped to the Guild.
|
|
|
|
- **Pattern:** The Controller maintains a `Map<GuildID, Player>`.
|
|
- **Behavior:**
|
|
- **Join:** Create a Player for `Guild A` if none exists.
|
|
- **Leave:** Destroy the Player and release connections.
|
|
- **Isolation:** Commands in `Guild B` never affect `Guild A`.
|
|
|
|
## 2. Command Orchestration
|
|
|
|
Voice features require a suite of commands coordinated via the Controller.
|
|
|
|
| Command | Action | Controller Logic |
|
|
| :------ | :----------------- | :---------------------------------- |
|
|
| `/join` | Connect to channel | `createPlayer(guildId, channelId)` |
|
|
| `/play` | Add track to queue | `getPlayer(guildId).enqueue(track)` |
|
|
| `/stop` | Disconnect | `destroyPlayer(guildId)` |
|
|
|
|
## 3. State Persistence
|
|
|
|
Audio sessions are ephemeral.
|
|
|
|
- **Transient State:** Active audio stream (Lost on disconnect).
|
|
- **Durable State:** Queue/Playlist (Persisted in Controller until restart).
|
|
|
|
> [!TIP] > **Resilience:** Separate the _Queue_ logic from the _Voice Connection_ logic. This allows the bot to reconnect without losing the user's playlist.
|
|
|
|
## 4. Implementation Sketch
|
|
|
|
```typescript
|
|
// lib/MusicController.ts
|
|
class MusicController {
|
|
private players = new Map<string, AudioPlayer>();
|
|
|
|
getPlayer(guildId: string): AudioPlayer {
|
|
if (!this.players.has(guildId)) {
|
|
this.players.set(guildId, new AudioPlayer());
|
|
}
|
|
return this.players.get(guildId);
|
|
}
|
|
|
|
destroyPlayer(guildId: string) {
|
|
this.players.get(guildId)?.disconnect();
|
|
this.players.delete(guildId);
|
|
}
|
|
}
|
|
```
