Godot shooter coming along, vehicle and player controller inside.

I'm steamrolling through code right now which is fantastic and will be posting some by the gods stuff eventually. Once you get over the initial teething problems of learning a new engine Godot is pretty straightforward considering how tedious I found ragdoll physics and vehicles in Unity. These are the two tutorials that I've used for reference.

        rotate_y(deg2rad(-1 * event.relative.x * mouseSensitivity))
