lloydwood Posted July 3, 2015 Share Posted July 3, 2015 Hello, How could I go about having drag only affect one direction? I basically want my particles to have drag equal to their velocity (airresist *= length(@v)) but only if they are moving up. If they are moving down I don't want them to have any drag.

Skybar Posted July 3, 2015 Share Posted July 3, 2015 If vel.y > 0 do drag else no drag Quote Link to comment Share on other sites More sharing options...

3iart Posted July 6, 2015 Share Posted July 6, 2015 Maybe I'm mistaken, but I believe air resistance differs from drag in that it is already velocity weighted. Quote Link to comment Share on other sites More sharing options...
