Unity（C#） 快速开始与功能指南

计划发布形态：
  1) UPM：Packages/manifest.json 里加 "com.nimeet.rtc": "file:../ni-meet/sdk/unity"
  2) 或导入 .unitypackage（Assets/Nimeet/Rtc）
Unity SDK 的安装与版本信息以发布包为准；本页示例按公开接口编写。

using Nimeet.Rtc;

public class MeetingController : MonoBehaviour, IRtcEngineEventHandler
{
    private IRtcEngine engine;

    void Start()
    {
        engine = RtcEngine.CreateAgoraRtcEngine();
        var context = new RtcEngineContext { appId = AppConfig.AppId, eventHandler = this };
        engine.Initialize(context);
        engine.SetChannelProfile(ChannelProfileType.ChannelProfileLiveBroadcasting);
        engine.EnableVideo();
        engine.StartPreview();

        var options = new ChannelMediaOptions
        {
            clientRoleType = ClientRoleType.ClientRoleBroadcaster,
            autoSubscribeAudio = true,
            autoSubscribeVideo = true,
        };
        engine.JoinChannel(AppConfig.RtcToken, "weekly-sync", 10001, options);
    }

    public void OnJoinChannelSuccess(RtcConnection connection, int elapsed) => Debug.Log("joined");
    public void OnUserJoined(RtcConnection connection, int remoteUid, int elapsed) { }
    public void OnUserOffline(RtcConnection connection, int remoteUid, UserOfflineReasonType reason) { }
    public void OnTokenPrivilegeWillExpire(string token) { engine.RenewToken(FetchFreshToken()); }
    public void OnError(int err, string msg) => Debug.LogError($"rtc {err}: {msg}");

    void OnDestroy() => RtcEngine.Destroy();
}

engine.MuteLocalAudioStream(true);
engine.MuteLocalVideoStream(true);
engine.EnableLocalVideo(false);
engine.UpdateChannelMediaOptions(options);
