An experiment I started using the GMS Physics Engine a while ago has become a kind of large project. I've hit a minor road-bump though, which would be slopes. The character goes up the slopes just fine, because when I apply the force to move I have a y force of -20. But when he stops moving he starts to slide back down again unless the slope is really small. I'm looking for a way to make it not slide down on slopes that are smaller than 45 degrees. I've tried many different methods, but none of them get quite the effect I'm looking for. I was wondering if anyone here had a preferred method? Your ideas would be very helpful, Thanks!
