B2.World:step

Available since: Gideros 2011.6

Description

Take a time step. This performs collision detection, integration, and constraint solution.

 b2.World:step(timeStep,velocityIterations,positionIterations)

'timeStep: (number) the amount of time to simulate, this should not vary '
'velocityIterations: (number) for the velocity constraint solver '
'positionIterations: (number) for the position constraint solver '
