Getting Started

You can use Lavalink4NET in 3 different modes: Cluster, Node and Rest.

• Cluster is useful for combining a bunch of nodes to one to load balance.
• Node is useful when you have a small discord bot with one Lavalink Node.
• Rest is useful when you only want to resolve tracks.

Using the constructor

Here is an example, how you can create the AudioService for a single node:

var audioService = new LavalinkNode(new LavalinkNodeOptions
{
	RestUri = "http://localhost:8080/",
	WebSocketUri = "ws://localhost:8080/",
	Password = "youshallnotpass"
}, new DiscordClientWrapper(client));

Usage with Dependency Injection / IoC (recommended)

var serviceProvider = new ServiceCollection()
	.AddSingleton<IAudioService, LavalinkNode>()	
	.AddSingleton<IDiscordClientWrapper, DiscordClientWrapper>();
	.AddSingleton(new LavalinkNodeOptions {[...]})
	[...]
	.BuildServiceProvider();
	
var audioService = serviceProvider.GetRequiredService<IAudioService>();

// Do not forget disposing the service provider!

Lookup the LavalinkNodeOptions in the application.yml of your Lavalink Node(s).

Initializing the node

Before using the service you have to initialize it, this can be done using the Ready event of your discord client implementation:

client.Ready += () => audioService.InitializeAsync();

Joining a voice channel and playing a track

// get player
var player = _audioService.GetPlayer<LavalinkPlayer>(guildId) 
    ?? await _audioService.JoinAsync<LavalinkPlayer>(guildId, voiceChannelId);

// resolve a track from youtube
var myTrack = await _audioService.GetTrackAsync("<search query>", SearchMode.YouTube);

// play track
await player.PlayAsync(myTrack);
