The player should slide instead of walk:
I tried it with the ground friction set to -14 ...but the player still get slowed down very hard when ever a face of a brush isn't in the same alignment as the former. A slight flattened angle and you get stuck instead of sliding over it.
When I tested this friction I noticed that the player still creates stepping noises ...it would be cool if I could change this into some kind of sliding noise.
The player should not receive any fall damage:
I know this was made before ...but I can't remember how.
I'll search tomorrow the solution in the wiki (I'm tired right now and go to sleep). But if someone in the meanwhile can nudge me into the right direction, that would be really nice
Ok I'm off. Good Night.

I just say, Down-Hill
