Cocos2d iphone COCOS2D:setOpacity=0不'；行不通

当touchended方法检测到第二次触摸时，我试图将精灵的不透明度设置为零

if语句中除setOpacity部分外的所有其他部分都有效

出于某种原因，它不希望将CCsprite的不透明度设置为零

我做错了什么

您是否通过设置断点来检查是否实际调用了带有setOpacity的行？如果你不知道怎么做

设置if/else if子句的方法仅在触摸位置在

animatingRuby3

和

touch==self.RubySecondTouch

的边界框上为而不是时才会运行该特定代码。从这些变量的名称推断，这似乎没有什么意义，也许这两个条件永远不会成立

以下代码简化为if语句：

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 ...
    }
}

这三条if语句中的其他所有内容都被调用为dupdate：如果我更改了[animatingRubyglow3 setOpacity:0]；至[动画Ruby3设置不透明度：0]；动画Ruby3是另一个CCSprite。那么它工作得很好。只是动画RubyGlow1、动画RubyGlow2和动画RubyGlow3 CCSprites无法将不透明度设置为零
