public int GetContacts (ContactPoint2D[] contacts);

파라미터

contacts An array of ContactPoint2D used to receive the results.

반환

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

설명

Retrieves all contact points for 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.

public int GetContacts (Collider2D[] colliders);

파라미터

colliders An array of Collider2D used to receive the results.

반환

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

설명

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.

public int GetContacts (ContactFilter2D contactFilter, ContactPoint2D[] contacts);

파라미터

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.

반환

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

설명

Retrieves all contact points for this collider, with the results filtered by the ContactFilter2D.
