| collider | The Collider that defines the area used to query for other Collider overlaps. |
| results | The list to receive results. |
int
Returns the number of results placed in the results list.
Gets a list of all Colliders that overlap the given Collider.
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.
The results can also be filtered by the contactFilter.

| contactFilter | The contact filter used to filter the results differently, such as by layer mask, Z depth. Note that normal angle is not used for overlap testing. |

| results | The array to receive results. The size of the array determines the maximum number of results that can be returned. |
int
Returns the number of results placed in the results array.
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.
