Godot: Changing the radius of a collision shape makes ALL the collision shapes change

[JarLowrey]

Godot version:
3.0

OS/device including version:
Win10

Issue description:
Old-ish issue. Encountered it on my project and found this QA post that explains it and the workaround very well

Steps to reproduce:

Have multiple nodes use the same CollisionShape2D and CircleShape2D. Change radius in script, it impacts all the shapes.

I think this is intended. You have to use "Make Unique" option.

Indeed, this is a feature. Either use "Make Unique" from the editor as shown above, or duplicate the shape from script if you want to edit it only for one instance.

Click Make Unique does not seem to solve the problem for me. All the collision shapes are still the same after doing this and changing their radius'es in a script. Setting a new shape in code does though:

#works!
    var shape = CircleShape2D.new()
    shape.set_radius(min(spriteShape.x,spriteShape.y)/2)
    $KinematicBody2D/CollisionShape2D.shape = shape

#doesnt work, even after setting "Make Unique" in the editor
    $KinematicBody2D/CollisionShape2D.shape.radius = min(spriteShape.x,spriteShape.y)/2

Did you click Make Unique after you duplicated a node, or before?

[JarLowrey]

I clicked "Make Unique" on the node in the editor. From the code I set the radius to different values, which does not work.

If I create a new node each time in the code, it works.

If you're using code to duplicate nodes, creating new shape is the right way. "Make Unique" is just creating new shape with the same property. If you duplicate nodes after you click "Make Unique", it will use the same shape.
