COCOS2D：setOpacity = 0不起作用

Question

我試圖在touchended方法檢測到第二次觸摸時將sprite上的不透明度設置爲零。

其他的一切，如果聲明工作除了setOpacity部分。

出於某種原因，它不希望設置不透明度設爲零CCsprite

我究竟做錯了什麼？

有你在設置斷點與setOpacity該行實際上被調用檢查？ Read this article如果你不知道該怎麼做。

的方式您設定的if/else如果如果觸摸位置是上的animatingRuby3和touch == self.RubySecondTouch boundingBox的不條款將只運行特定的代碼。從這些變量的名稱推測，這似乎沒有道理，也許這兩個條件永遠不會是真的？

下面的代碼減少到僅僅是if語句：

if(CGRectContainsPoint([animatingRuby3 boundingBox], location)){ 
    } 
    //Else return the rubys to their original size and stop the action 
else if (touch == self.RubySecondTouch) { 
    if(PulsatingAnimeRuby1){ 
     // opacity is set here ... 
    } 
}
