As far as I can tell, in Craft the only way to know the size of a rigidbody is to keep track of it at the moment of creation.
There doesn’t seem to be a way to inspect a rigibody to determine its size—or am I missing something?
It would be really useful to have a “make shape visible” toggle on a rigidbody so you could see it and make sure it’s the same size as an entity’s model.
Do you mean the overall bounding box of the rigidbody? I haven’t put something like that in Craft but it could be added. There are two kinds of bounds, the oriented bounds and the axis aligned bounds. Oriented bounds is in local space and purely measures overall size, where the AABB is more the space it takes up in the world accounting any orientation (like a box that is stretched over the object)
In Codea 4 I have a debug draw option for both 2D and 3D physics (see the attached image)
