| 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 this collider.
Contacts involving a Collider2D set to be a trigger will never be returned here as trigger colliders do not have contact points.
You should pass an array that is large enough to contain all the contacts you want returned. This array would typically be reused so it should be of a size that can return a reasonable quantity of contacts. No allocations occur in this function which means no work is produced for the garbage collector.

| colliders | An array of Collider2D used to receive the results. |
int
Returns the number of contacts placed in the colliders array.
Retrieves all colliders in contact with this collider.
You should pass an array that is large enough to contain all the contacts you want returned. This array would typically be reused so it should be of a size that can return a reasonable quantity of contacts. No allocations occur in this function which means no work is produced for the garbage collector.

| contactFilter | The contact filter used to filter the results differently, such as by layer mask, Z depth, or normal angle. |
| 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 this collider, with the results filtered by the ContactFilter2D.
Contacts involving a Collider2D set to be a trigger will never be returned here as trigger colliders do not have contact points. This is true even if the contactFilter has its ContactFilter2D.useTriggers set to true.
