此次在之前那篇cocos2dx A* + tiledMap文章中新加了些功能并且调整了结构

拥有的功能:

能避开障碍物,搜寻最优路径

优化了行走的路径,使之平滑行走(之前的是瓦片级的, 现在是像素级的, #define PRECISE_SEARCH_PATH 开启精确的路径行走)

添加了人物根据位置会被物体遮住或遮住物体的功能

添加了点击路面, 到达该点. 点击物体, 可以到达该物体的功能

添加了捡拾物体功能

添加了坐椅子功能

添加了人物的骨骼动画(行走和站立)

PathSearchInfo 搜索路径引擎

Player 玩家类

PathSprite 瓦片精灵类

Paddle物体类(桌子,椅子等)

MathLogic 数学逻辑类
