| contacts | An array of ContactPoint2D used to receive the results. |
int
Returns the number of contacts placed in the contacts array.
Retrieves all contact points for contacts between collider and otherCollider.
When retrieving contacts, you should ensure that the provided array is large enough to contain all the contacts you are interested in. The array is usually reused, so it should be large enough to return a reasonable quantity of contacts. This function also means that no allocations occur, which means no work is produced for the garbage collector.
You can check how many contacts are available using contactCount.
