Method Detail

applyForces

public abstract void applyForces(double t)

Description copied from interface: ForceEffector

Adds forces to the components affected by this force effector at a particular time. Component forces should be added and not set, since other forces may be added to the same components by other force effectors.

Specified by:

applyForces in interface ForceEffector

Parameters:

t - time (seconds)
