The physics layers this area is in.

Collidable objects can exist in any of 32 different layers. These layers work like a tagging system, and are not visual. A collidable can use these layers to select with which objects it can collide, using the :ref:`collision_mask<class_PhysicsBody_property_collision_mask>` property.

A contact is detected if object A is in any of the layers that object B scans, or object B is in any layer scanned by object A. See `Collision layers and masks <https://docs.godotengine.org/en/latest/tutorials/physics/physics_introduction.html#collision-layers-and-masks>`_ in the documentation for more information.
