| collider | 定义用于查询其他碰撞体重叠的区域的碰撞体。 |
| results | 用于接收结果的列表。 |
int
返回放置在 results 列表中的结果数。
Gets a list of all Colliders that overlap the given Collider.
该整数返回值是写入到 results 列表中的结果数。如果结果列表中没有足够的元素来报告所有这些结果，则会调整列表的大小。这可在 results 列表无需调整大小时防止为结果分配内存，可在经常执行查询时提高垃圾收集性能。
也可以通过 contactFilter 对结果进行筛选。

返回放置在 results 数组中的结果数。
Gets a list of all Colliders that overlap the given Collider.
The integer return value is the number of Colliders that overlap the Collider and which could be stored in the supplied array given its length. The results array will not be resized if it doesn't contain enough elements to report all the results. The significance of this is that no memory is allocated for the results and so garbage collection performance is improved when the check is performed frequently.
