Description
|
|
-----------
|
|
|
|
This is the CSG base class that provides CSG operation support to the various CSG nodes in Godot.
|
|
|
|
\ **Note:** CSG nodes are intended to be used for level prototyping. Creating CSG nodes has a significant CPU cost compared to creating a :ref:`MeshInstance<class_MeshInstance>` with a :ref:`PrimitiveMesh<class_PrimitiveMesh>`. Moving a CSG node within another CSG node also has a significant CPU cost, so it should be avoided during gameplay.

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 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 <../tutorials/physics/physics_introduction.html#collision-layers-and-masks>`__ in the documentation for more information.

Adds a collision shape to the physics engine for our CSG shape. This will always act like a static body. Note that the collision shape is still active even if the CSG shape itself is hidden.
