Declaration

public static bool IsTouchingLayers(Collider2D collider, int layerMask = Physics2D.AllLayers);

Parameters

Collider The Collider to check if it is touching Colliders on the layerMask.
layerMask Any Colliders on any of these layers count as touching.

Returns

bool Whether the Collider is touching any Colliders on the specified layerMask or not.

Description

Checks whether the Collider is touching any Colliders on the specified layerMask or not.

It is important to understand that checking if Colliders are touching or not is performed against the last physics engine update i.e. the state of touching Colliders at that time. If you have just added a new Collider2D or have moved a Collider2D but a physics update has not yet taken place then the Colliders will not be shown as touching. The touching state is identical to that indicated by the physics collision or trigger callbacks.
