cocos creatoe v2.0.2
运行cocos的tilemap项目发现一个问题，puzzle代码中的两处cc.pointEqualToPoint调用会报错：
Simulator: ERROR: TypeError: cc.pointEqualToPoint is not a function. (In ‘cc.pointEqualToPoint(this._curTile, this._endTile)’, ‘cc.pointEqualToPoint’ is undefined), location: assets/cases/tiledmap/Puzzle.js:229:33
请大神们看一下，指点一下，谢谢
