I think a lua script, where you press a key and the player selected would get back on his feet, should be made!
So many times have i tried, only to end up with him standing up cross-legged. I ask for this because (& yes i know it kills the fun of disses) Im a player who, don't really try to do all that, flippy-kick in the crotch, kinda stuff. I just play to... well, play.
And if one leg is missing he could try to get up, but fall.
And a script that lets you change the amount of force when flexing and stuff.
That is all.
