GetContacts(Collider2D, Collider2D, ContactFilter2D, ContactPoint2D[])
Retrieves all contact points in for contacts between with the collider1 and collider2, with the results filtered by the ContactFilter2D.
public static int GetContacts(Collider2D collider1, Collider2D collider2, ContactFilter2D contactFilter, ContactPoint2D[] contacts)
Parameters
The Collider to check if it has contacts against collider2.
The Collider to check if it has contacts against collider1.
The contact filter used to filter the results differently, such as by layer mask, Z depth, or normal angle.
An array of ContactPoint2D used to receive the results.
Returns
Type | Description |
|---|---|
| int | Returns the number of contacts placed in the contacts array. |
Remarks
Contacts involving a Collider2D set to be a trigger will never be returned here because trigger Colliders do not have contact points. This is true even if the contactFilter has its ContactFilter2D.useTriggers set to true.
When retrieving contacts, you should ensure that the provided array is large enough to contain all the contacts you are interested in. Typically the array would be reused therefore it would be a size 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.
