Google Cast 游戏管理器接收器

Question

我在尝试启动并运行 Cast Game Manager 时遇到了一个不知道如何修复的错误。我已经能够连接游戏管理器，并获得状态更新。在此之后，我尝试发送 PlayerAvailableRequest。接收方更新游戏调试 ui 以指示请求成功，但随后在尝试将其响应消息发送给发送方时崩溃。下面我附上了相关的控制台日志，以及 GameDebug UI 的图片。请让我知道我是否遗漏了什么。

编辑：我已通过 addGameManagerListener 将其范围缩小到使用 GameManagerListener。我已经让我的听众像示例一样简单，但它仍然崩溃。

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);

抱歉 - 这是因为 documentation guide 中的错误：

• GameManagerListener 示例缺少其他方法 覆盖。
• 在结尾的分号前有一个“)” 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，你需要添加：

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

至于实现定义的 GameManager 属性的回调，请确保没有语法错误，例如

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

而不是

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

再次道歉 - 我们会修复文档。 :)

好的，我将我的解决方案发布给其他遇到相同问题的实施此问题的人。

在文档中指出， "使用 GameManager 设置请求事件回调的三种方法。

• 为特定请求调用 addEventListener 方法。
• 为定义的 GameManager 属性实现回调。
• 调用 addGameManagerListener 方法提供一个对象（实现 GameManagerListener）来处理所有请求。 "

事实证明，似乎只有 addEventListener 方法有效。当我创建一个类并将其添加为侦听器时，我得到了我在原始问题中发布的错误。当我实现回调时，没有被击中。我不确定这是否是由于我正在做的事情，但是，再次，似乎只有 addEventListener 有效。
