int
返回放置在 results 数组中的结果数。
获取与该碰撞体重叠的所有碰撞体的列表。
The integer return value is the number of colliders that overlap this 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 query is performed frequently.

void
Returns the number of results placed in the results list.
Get a list of all Colliders that overlap this Collider.
The integer return value is the number of Colliders that overlap this Collider with the specific Colliders stored in the supplied list. The results array will not be resized if it doesn't contain enough elements to report all the results. 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.
