Beginner-friendly GDScript 1 to GDScript 2 Conversion Guide

First and foremost, this should not be considered a replacement for the official migration guide, 
found at https://docs.godotengine.org/en/latest/tutorials/migrating/upgrading_to_godot_4.html! 
Instead, this document is intended to be a friendly guide to helping you upgrade your projects from 
GDScript 1 to 2. To do this, I'm going to list the most common conversions I've run into while upgrading 
a few of my games and tools. This document is written as of the first release candidate version of Godot 4.0.

The first thing to do when converting a project (no need if you're starting from new) is to either have your
project in source control, or make a duplicate of your entire project's folder and rename it. This will

# If you intend to use this, don't forget to turn on camera rotation! And keep in mind that smaller numbers are often the most useful - huge numbers make this thing *really* shake

export var decay = 0.8  # How quickly the shaking stops [0, 1].

export var max_roll = 0.1  # Maximum rotation in radians (use sparingly).

This document represents the beginning of an upgrade or migration document for GDScript 2.0 and Godot 4.0. I'm focusing on 2D
at the moment as I'm upgrading a 2D game, but will hopefully have more to add for 3D afterward.

## If you want more content like this, please help fund my cat's medical bills at https://ko-fi.com/kyleszklenski - thank you very much! On to the migration guide.
