In forge, you can create gravity areas that change how the player moves.
Unfortunately I cant seem to be able to change the size of teh default gravity zones.
Its stuck on 5X5 and 10X10 i think. And when i change the shape it just inserts a smaller zone inside the 5X5/10X10, and doesnt change the area u are effected by at all.
Additionally i dont seem to be able to change the strength of the gravity. Do u have to just overlap the zones?
