I am working on the input and it feels like its getting out of hand. I wanted to check in with people and see how people structure their input handling.
Currently I have 1 function _unhandled_unput(event) and inside there I have a ton of elif statements trying to handle every possible situation and event. Its manageable at the moment but I only have like 4 events so its going to get very out of hand if I continue.
I need to have 100s of these events based on whats selected and what mouse/keyboard buttons are being pressed and I need some way to resuse the actions.

if event is InputEventMouseButton and event.pressed:

colonist.set_state("DRAFT")

#nothing selected dragbox to select things and single click to select things - does not work at the moment

I just dump a lot of if statements into _process. One thing good about it is that it gets rid of some nesting and shortens it a bit
