| Collider | The Collider to check if it is touching Colliders on the layerMask. |
| layerMask | Any Colliders on any of these layers count as touching. |
bool
Whether the Collider is touching any Colliders on the specified layerMask or not.
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.
