| collider | The Collider to retrieve contacts for. |
| colliders | A list of Collider2D used to receive the results. |
void
Returns the number of Colliders placed in the colliders list.
Retrieves all Colliders in contact with the 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.
