Unity quickstart (WebGL)

1. Install LiveKit SDK

Click the Add + menu in the Package Manager toolbar, select Add package from git URL, and enter: https://github.com/livekit/client-sdk-unity-web.git

For more details, see the Unity docs on installing packages from Git URLs.

2. Connect to a room

Note that this example hardcodes a token. In a real app, you’ll need your server to generate a token for you.

public class MyObject : MonoBehaviour
{
    public Room Room;

    IEnumerator Start()
    {
        Room = new Room();
        var c = Room.Connect("<your LiveKit server URL>", "<generate a token>");
        yield return c;

        if (!c.IsError) {
            // Connected
        }
    }
}

3. Publish video & audio

yield return Room.LocalParticipant.EnableCameraAndMicrophone();

4. Display a video on a RawImage

RawImage image = GetComponent<RawImage>();

Room.TrackSubscribed += (track, publication, participant) =>
{
    if(track.Kind == TrackKind.Video)
    {
        var video = track.Attach() as HTMLVideoElement;
        video.VideoReceived += tex =>
        {
            // VideoReceived is called every time the video resolution changes
            image.texture = tex;
        };
    }
};
