public method OverlapCollider(contactFilter: ContactFilter2D, results: Collider2D[]): int;
public int OverlapCollider(ContactFilter2D contactFilter, Collider2D[] results);

Parameters

contactFilter The contact filter used to filter the results differently, such as by layer mask, Z depth. Note that normal angle is not used for overlap testing.
results The array to receive results. The size of the array determines the maximum number of results that can be returned.

Returns

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

Description

Get a list of all colliders that overlap all colliders attached to this Rigidbody2D.

The integer return value is the number of colliders that overlap the collider and which could be stored in the supplied array given its length. The results array will not be resized if it doesn't contain enough elements to report all the results. The significance of this is that no memory is allocated for the results and so garbage collection performance is improved when the check is performed frequently.
