Just... just trust me

Is ok.
Iso camera, movement, shooting, walking up slopes

Yee buddy you better believe it.
-Isometric camera, follows the player at a set distance
-Player movement. WASD. There is an option (in the code) to use WASD and
mouselook, but that's a bit weird.
-Collision. Player collides with obstructions and the ground. He can go
up some slanted objects, up to like 45 degrees it seems.
-Shooting. He shoots a gun, it plays a noise and shows a flash of light.
There's a public var (GunType) you can change. Auto means you can hold
click to fire, otherwise, just 1 click = 1 shot.

Assets>Scenes>Sandbox is the scene to load.
