Transforms in Godot - elegantly solve game programming problems without being a math wizard

Hello Godotneers! When we make games we very often have to do calculations in 2D or 3D space to find out in which direction a character should walk, a projectile should fire or how to rotate a camera when the player moves the mouse. This often requires quite a bit of math which can be challenging in 2D and gets even more complicated in 3D. Godot's transforms provide us with a very neat and elegant way to solve a lot of these problems without needing a math degree. We're going to see how transforms work under the hood and how we can use this information to do things like moving a character relative to his orientation, shooting bullets from the player perspective without calculating a lot of angles and positions, controlling first and third person cameras and build useful node structures that let us do all of this with very little, readable code. So fire up Godot, download the example project and have some fun!
