Here's the thing: on a flat surface it is above the terrain, but as it ecounters a slope, the bottom corners may dip slightly below, I think that this causes the sticking; however, decreasing the bounding box value results in a different gravity calculation, to the same end. In essesence, decreasing the bounding box value lowers the player into the terrain and the player will still stick on some slopes. I added "-5" to my ground_dist trace and achieved some success, but the sticking still occurs on steep slopes because the corners will still collide with the terrain.

EDIT: I was actually doing some thinking, I'm at work now and can't test it until I get home, but if I decreased the bounding box size by say 10 and then decreased the "-5" to "-10", what I may be left with is a bounding box that is technically off the ground a little and the model being offset to twice that creating the illusion that it is off the ground. I may have phrased this wrong, but I can see the meaning in my mind lol. I will post an update when I give it a test run with corrected code and comments to help other people because I am sure that I'm not the only one with this problem.

EDIT: Er, rather; offset by the same amount...
