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.
Get a list of all colliders that overlap this collider.
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.

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 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.
