Google Cast Game Manager Receiver

Question

我遇到了一個錯誤，我不知道如何解決在試圖讓Cast Game Manager啓動並運行時如何解決這個問題。我已經能夠連接遊戲管理器，並獲得狀態更新。在此之後，我嘗試發送一個PlayerAvailableRequest。接收者更新遊戲調試ui，指示請求成功，但在嘗試將其響應消息發送給發件人時崩潰。下面我附上了相關的控制檯日誌，以及GameDebug UI的圖片。請讓我知道，如果有什麼我在我的最後失蹤。

編輯：我已經將範圍縮小到通過addGameManagerListener使用GameManagerListener。我讓聽衆像例子一樣簡單，但它仍然崩潰。

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); 

Answer 1

好吧，我發佈我的解決方案，爲其他任何人執行此問題有相同的問題。

在它指出， 「有三種方式來設置請求事件回調與遊戲管理的文檔。

• 徵集具體要求addEventListener方法。
• 的定義實施回調遊戲管理財產。
• 調用addGameManagerListener方法來提供一個對象（即實現GameManagerListener）來處理所有請求。「

事實證明，只有addEventListener方法似乎工作。當我創建一個類並將其添加爲偵聽器時，我收到了我在原始問題中發佈的錯誤。當我實現回調時，沒有人被擊中。我不確定這是否是由於我正在做的事情，但是，再次，只有addEventListener似乎工作。

對不起 - 這是因爲在documentation guide的錯誤：

• 的GameManagerListener樣品缺少其他方法來 覆蓋。
• 在 結尾處有一個以「;」結尾的分號，表示實現GameManager屬性的示例。

對於addGameManagerListener，實現所有在https://developers.google.com/cast/docs/reference/receiver/cast.receiver.games.GameManagerListener

例如列出的GameManagerListener的方法，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() {}; 

至於實施的定義遊戲管理財產的回調，使確定沒有語法錯誤，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 - 我們將得到的文檔固定。 :)
