中間遇到過很多問題

比如 隨機數，開始隨機產生 座標，卻會出現一直迴圈，就是隨機不到最後一個空的格子。

我就用了隊列，把所有空的格子入隊，然後隨機出幾個隊，選一個就好。

還有觸摸方向，我檢測的是起點和終點的 座標 x ,y 的距離。然後判斷上下左右。

最麻煩的是 移動的時候上下左右了，剛好和座標系的有點不一樣。

我是採用的矩陣數組，左上方是0，0 。而計算座標的時候 左下角才是初始。然後就要 一個加，一個減。

遊戲結束後，螢幕滑動還能繼續，又憂傷我半天，最後就 加上觸摸關閉。

cocos2d-x31添加返回鍵監聽報錯，不知道為何捕捉不到？

你這個

音效檔案貌似沒找到吧。
 
cocos2d-x-32在VS2010產生解決方案失敗？
