B2.World:clearForces

Available since: Gideros 2011.6
Class: b2.World

Description

Call this after you are done with time steps to clear the forces. You normally call this after each call to b2.World:step,
unless you are performing sub-steps. By default, forces will be automatically cleared, so you don't need to call this function.
