| index | The index of the path from 0 to pathCount minus 1. |
| points | An ordered array of the vertices (points) in the selected path. |
int
返回放置在 points 数组中的点数。
根据碰撞体的索引获取其路径。
路径 是在定义碰撞体轮廓的各点之间的线段的循环序列。碰撞体可能有孔和不连续部分，因此其形状不一定由单个路径定义。

The integer return value is the number of results written into the results list. The results list will be resized if it doesn't contain enough elements to report all the results. This prevents memory from being allocated for results when the results list does not need to be resized, and improves garbage collection performance when the query is performed frequently.
