javascript - Google Cast游戏管理器接收器

我遇到了一个错误，在尝试启动和运行Cast Game Manager时，我不确定如何解决。我已经能够连接游戏管理员，并获得状态更新。此后，我尝试发送一个PlayerAvailableRequest。接收方更新游戏调试ui，以指示请求已成功，但是随后在尝试将其响应消息发送给发送方时崩溃。在下面，我附上了相关的控制台日志以及GameDebug UI的图片。请让我知道我末端是否缺少某些东西。

编辑：我已经将其范围缩小到通过addGameManagerListener使用GameManagerListener。我已经使我的侦听器与示例一样简单，但是仍然崩溃。

Game Manager Listener Object:
MyGame = function () {
};

MyGame.prototype.onPlayerAvailable = function (event) {
    console.log('Player ' + event.playerInfo.playerId + ' is available');
};

MyGame.prototype.onPlayerReady = function () { };
MyGame.prototype.onPlayerIdle = function () { };
MyGame.prototype.onPlayerPlaying = function () { };
MyGame.prototype.onPlayerDropped = function () { };
MyGame.prototype.onPlayerQuit = function () { };
MyGame.prototype.onGetGameManagerStatus = function () { };
MyGame.prototype.onGameMessage = function () { };
MyGame.prototype.onGameLoading = function () { };
MyGame.prototype.onGameRunning = function () { };
MyGame.prototype.onGamePaused = function () { };
MyGame.prototype.onGameShowingInfoScreen = function () { };
MyGame.prototype.onLobbyOpen = function () { };
MyGame.prototype.onLobbyClosed = function () { };

line adding it:
this.mMyGame = new MyGame();
this.mCastGameManager.addGameManagerListener(this.mMyGame);

最佳答案

抱歉-这是因为documentation guide中的错误：


GameManagerListener示例缺少其他方法来
覆盖。
在末尾的分号前有一个“）”
实现GameManager属性的示例。


对于addGameManagerListener，实现https://developers.google.com/cast/docs/reference/receiver/cast.receiver.games.GameManagerListener中列出的GameManagerListener的所有方法。

例如，您需要添加：

MyGame.prototype.onGameMessageReceived = function() {};
MyGame.prototype.onGameDataChanged = function() {};
MyGame.prototype.onPlayerDataChanged = function() {};
MyGame.prototype.onGameDataChanged = function() {};
MyGame.prototype.onGameStatusTextChanged = function() {};

至于为定义的GameManager属性实现回调，请确保没有语法错误，例如

gameManager.onPlayerAvailable = function(event) {
    console.log('Player ' + event.playerInfo.playerId + ' is available');
};

并不是

gameManager.onPlayerAvailable = function(event) {
    console.log('Player ' + event.playerInfo.playerId + ' is available');
});

再次道歉-我们将修复文档。 :)
