CollisionShape2D

Sim

I'm attempting to iterate through and collect all collision shapes in my scene, but the documentation states that CollisionShape2D is an editor-only facility. Does this mean I cannot use something like "if obj is CollisionShape2D:"?

I think you can use it, as it's the node that you need to add as a child of RigidBody2D, KinematicBody2D, and StaticBody2D nodes to assign shapes to them. I'm not sure what the documentation means by it being an editor-only helper. My guess is that it means it doesn't represent the shape itself directly in the node, as the node likely sends it's shape data to the physics server on initialization. I think it should be fine to use.

I think the docs are correct. If you want to get any parameters (like the extents of the shape), then you have to get the shape itself. Though this is rarely, if ever, actually needed in a game. You typically just want to deal with the StaticBody2D or other nodes that are controlling the shape. Like for collision code in your example, you would be checking StaticBody2D not CollisionShape2D. And in any case, you rarely ever need to explicitly check for StaticBody2D either. You would use signals or callback functions (like get_overlapping_bodies) and never check the type specifically.
