一、环境：

cocos2d-x 3.0      PhysicsEditor 1.0.10

二、cocos2d-x 3.0 篇：

从cocos2d-x 3.0 可以在scene 中直接添加物理世界后，开发物理效果的2d游戏相对轻松多了。可是编辑多边形的body 就成了问题，之前-x 2.x 版的PE loader 没有目前 CCPhysicsBody 的封装。本人就参考 之前的-x 2.x 版的loader 写了一个-x 3.x 版的PE laoder,加载 chipmunk shapes ，并根据图片名 获得CCPhysicsBody。     测试代码如下：` #include "HelloWorldScene.h"    #include "VisibleRect.h"    #include "ResourcesPath.h"    #include "PEShapeCache_X3_0.h"    USING_NS_CC;
