public method GetContacts(contacts: ContactPoint2D[]): int;
public int GetContacts(ContactPoint2D[] contacts);

Parameters

contacts An array of ContactPoint2D used to receive the results.

Returns

int Returns the number of contacts placed in the contacts array.

Description

Retrieves all contact points in 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. 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.
