Report article RSS Feed Negative Friction

Posted by ~WILLAM~ on Feb 11th, 2014

Playtesting Optic the other day, I decided to edit some of the code. I unhid some developer only commands inside movevars_shared.cpp, one of those being sv_friction. Now, funnily enough I'd just seen a video of GTA IV's Carmageddon mod, which sets the friction on car's wheels to negative. Now, friction essentially slows stuff down, so when it's negative, what's gonna happen? Stuff's gonna speed up.

I set sv_friction to -5, raised the velocity cap to about 150,000 and tapped the forward key.

See my velocity? That little 'vel' at the top right. Sprinting speed is 320. I got over 3,000 just by moving down quite a short corridor. The view was messing up a little bit, the camera bob which is set to match you speed was almost seizure inducing, and when I hit that wall I actually lifted off of the ground and hit the ceiling.

Don't play with friction, kids.

On a slightly more serious note, a multiplayer FPS where players are in maps filled with physics props that have negative friction would be great. Rounds start with a little earthquake in just one room, making the props fly, and players have to kill each other as the props fly about, adding more chaos. The catch? Hit a prop with a bullet, nudge a prop, or let other props get too close to static props, and that untouched prop is gonna start whizzing about as well.

Damn, I need to make that now. At some point, I'll get around to trying it.
