(cocos2dx)使用__Array容器检测碰撞时间

概述同样是学了别人教学视屏上的代码，但是在执行的时候发现在使用CCArray的时候，运行会报错。 然后我就翻了一下书，CCArray是2.x版本的，3.x是用__Array。 两者在创建时是有所不同的。 后来我就把里面用CCArray定义的都改成__Array来定义，就能正常运行。 #include "HelloWorldScene.h"USING_NS_CC;Scene* HelloWorl

同样是学了别人教学视屏上的代码，但是在执行的时候发现在使用CCArray的时候，运行会报错。

然后我就翻了一下书，CCArray是2.x版本的，3.x是用__Array。

两者在创建时是有所不同的。

后来我就把里面用CCArray定义的都改成__Array来定义，就能正常运行。
