There isn't any method to access a CSG node collision shape

[Axeltherabbit]

Describe the project you are working on

I'm manipulation CSG nodes and I would like to access the resulting collision shape or mesh.
There is the method get_meshes but it only works when the node is the root of the scene, I don't really understand why, it's a bit strange for my little understanding

Describe the problem or limitation you are having in your project

• If the flag use collisions is on it acts like a StaticBody but I can't access the collision shape or other StaticBody methods.
• At the moment CSG are limited to StaticBodies, I can't work with RigidBodies

Describe the feature / enhancement and how it helps to overcome the problem or limitation

It would make CSG nodes more free

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

I would just add;

• a method csgroot.get_resulting_mesh to get the result of the boolean operations
• csgroot.get_collision_shape

If this enhancement will not be used often, can it be worked around with a few lines of script?

My c++ and engine understanding is poor but the shape is already there, I believe it would need few extra lines to access it
Looks like the code is there, we just need the methods

Is there a reason why this should be core and not an add-on in the asset library?

CSG nodes are being developed right now and they improved a lot.
I understand that they are designed for quick use but I think it is a bit strange that use collisions creates a StaticBody like object rather then an actual StaticBody.
I have also found this old issue

I have made a first test and it seems quite easy to change commit

Any updates on this issue?

I stopped to work on this because godot 4 was about to be released then forgot, I'll have a look later this weekend

I ran into this use case recently and resorted to defining a bunch of capsules to 'mimic' my CSG polygon, would be incredibly grateful if we could access the CSG collision shape, and I'm sure i'm not the only one.
Much appreciated :)
