How did you add collision?

I'm looking at your code, and the block.tscn only has a rigid body as a root node, and a sprite and visibility notifier as children. How did you get your subdivided blocks to have collision? My hitboxes just seem to stay the same size as the original block.

I'm using Godot 3 by the way, so I'm not sure if it applies anymore.
