spine骨骼动画构造包围盒问题

Creator 2.x

  • Creator 版本：2.2.0

  • 目标平台： Web模拟器

  • 详细报错信息，包含调用堆栈：
    CCPolygonSeparator.js:337 Uncaught TypeError: Cannot read property ‘x’ of undefined
    at Area (CCPolygonSeparator.js:337)
    at Right (CCPolygonSeparator.js:219)
    at Reflex (CCPolygonSeparator.js:207)
    at ConvexPartition (CCPolygonSeparator.js:77)
    at ConvexPartition (CCPolygonSeparator.js:154)
    at ConvexPartition (CCPolygonSeparator.js:154)
    at Object.ConvexPartition (CCPolygonSeparator.js:154)
    at cc_PhysicsPolygonCollider._createShape (CCPhysicsPolygonCollider.js:56)
    at cc_PhysicsPolygonCollider.__init (CCPhysicsCollider.js:172)
    at CCClass.pushDelayEvent (CCPhysicsManager.js:165)

  • 重现方式：
    遍历某spine的所有slot，对attachment做attachment.computeWorldVertices获取所有顶点，将所有顶点保存以后做凸包集，根据凸包集的坐标点去创建一个cc.PhysicsPolygonCollider，每帧循环调用，会出现如上错误。

  • 出现概率：每秒会出现很多次，降低帧率也会降低发生次数
