public static function GetContacts(collider: Collider2D, colliders: Collider2D[]): int;
public static int GetContacts(Collider2D collider, Collider2D[] colliders);

Parameters

collider The collider to retrieve contacts for.
colliders An array of Collider2D used to receive the results.

Returns

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

Description

Retrieves all colliders in contact with the collider.

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.

public static function GetContacts(collider: Collider2D, contacts: ContactPoint2D[]): int;
public static int GetContacts(Collider2D collider, ContactPoint2D[] contacts);

Parameters

Returns

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

Description

Retrieves all contact points in contact with the collider.
