Hello. Concerning this script, I know it's not possible to edit wall height (although it's possible to change wall distance). However, is there a way to change or adjust the camera height or viewport, so that the perspective is closer to the ground, or even higher that it? This could be used so that, while not changing wall height, it would seem walls were higher (even if it meant the player was lower), or even to simulate going up stairs (assuming it would be possible to have the engine render the ceiling tiles as if they were at ground level, due to a higher viewport).
Thanks in advance.
