setWorldSpaceMovement
Description
On enabling this via events, your forward movement key moves you north, your backward movement key moves you south, left strafe = west, right strafe = east.
It was a default function that was left completely unused until now as far as I know. Movement speeds have also been "fixed" so moving south for example wouldn't be slower than moving north.
Use it with set2DCamera.
You should also use it with a playertype that restricts players from looking up or down, like the Top Down Player.
