public class JImpulseDaemon

extends JDaemon

implements ImpulseForceListener

Force daemon element in the world

A force daemon is a special daemon that affects only atoms when they collide with it.

A force daemon applies a specific force to all atoms that collide with it. An impulse daemon applies a specific impulse to the atom, which is a force that will act on the atom for a certain period of time.
