Question

我试图在精灵方法检测到第二次触摸时在精灵上将不透明度设置为零。

除了setOpacity部分之外，if语句中的所有其他内容都可用。

出于某种原因，它不希望将CCacity的Opacity设置为零

我做错了什么？

您是否通过设置断点来检查实际调用了setOpacity的行？ Read this article如果您不知道该怎么做。

如果animatingRuby3和touch == self.RubySecondTouch的边界框上的触摸位置不是，则设置if / else if子句的方式只会运行该特定代码。从这些变量的名称推断出来似乎没什么意义，也许这两个条件永远不会成真？

这里的代码简化为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 ...
    }
}

COCOS2D：setOpacity = 0不起作用
