场景搭建（抖音小游戏）

SDK集成

为了保证最佳体验效果，本场景需要集成抖音开放平台并接入 RTC 服务，您需要在 RTC 的控制台开通服务，并搭建抖音开放平台开发环境，相应开通指南如下：

• 接入RTC 服务，请参看 RTC服务开通指南。
• 搭建抖音开放平台开发环境，请参看抖音小游戏RTC实时语音文档介绍。

业务实现流程

房间列表逻辑

游戏业务逻辑

• 房间列表页，用户可加入或者创建游戏房间

• 开始游戏时，服务端为每个玩家分配角色

• 通过广播控制狼人杀流程以及管理不同角色的麦位

核心功能实现

创建、加入房间流程

示例代码

//初始化RTCEngine并加入房间
    private void initRTCEngine()
    {
        var appid = RoomDataManager.Instance.RoomData.app_id;
        var roomid = RoomDataManager.Instance.RoomData.room_id;

    // 音量回调
    private void OnAudioVolumeIndication(string uid, int volume, int speakerNum)

                return;
            }

            MicBack.SetActive(volume > 0);
            BarController.UpdateVolume(volume, 255);

        }

        for (int i = 0; i < RoomDataManager.Instance.UserList.Count; i++)
        {
            if (i > 2)
            {

            playerController.BarController.UpdateVolume(volume, 255);
            return;
        }
    }

游戏流程

所有玩家加入一个RTC房间
天黑，狼人可以互相对话，且其他角色无法收听到对话内容

示例代码

//游戏阶段改变
    private void changeGameStatus(GameStatus gameStatus)
    {
        RoomDataManager.Instance.GameStatus = gameStatus;

        RtcEngine.MuteLocalAudioStream();
        isMuteMic = true;
        if (RoomDataManager.Instance.GameStatus == GameStatus.WolfSpeaking && RoomDataManager.Instance.RoleType == RoleType.Person)
        {
            RtcEngine.MuteAllRemoteAudioStream();
        }
        else
        {
            RtcEngine.UnMuteAllRemoteAudioStream();

        }

        refreshBackgroundUI();
        refreshBottomUI();
        refreshTipsUI();
    }
    
    //退出RTC房间
    private void leaveRoom()
    {
        RtcEngine.OnJoinChannelSuccessEvent -= OnJoinChannelSuccess;
        RtcEngine.OnUserJoinedEvent -= OnUserJoined;
        RtcEngine.OnUserOfflineEvent -= OnUserOffline;
        RtcEngine.OnUserMuteAudioEvent -= OnUserMuteAudio;
        RtcEngine.OnWarningEvent -= OnWarning;
        RtcEngine.OnErrorEvent -= OnError;
        RtcEngine.OnAudioVolumeIndicationEvent -= OnAudioVolumeIndication;

        // 关闭音频发送
        RtcEngine.MuteLocalAudioStream();
        // 关闭音频采集
        RtcEngine.DisableLocalAudio();
        // 离开房间
        RtcEngine.LeaveChannel();

        NetWorkManager.Instance.OffDisconnected(OnDisconnected);
        NetWorkManager.Instance.RemoveAllNotification();
        RoomDataManager.Instance.ClearData();
        RoomDataManager.Instance.OnUserJoinRoom = null;

        SceneManager.LoadScene("RoomListScene");
    }
