Need to build a loading screen in Godot? I took the resource queue example from the Godot Documentation, and cleaned it up a bit and put it in its own repo. This allows for background loading, a progress bar type screen, etc.
Maybe other people will find a use for it! Check it out here: Godot Resource Queue
Or just get the relevant file:
wget https://bitbucket.org/michaelb/godot-resource-queue/raw/master/ResourceQueue.gd
