Constructor Detail

UniversalGravity

public UniversalGravity(World world,
                        Body body)

Parameters:

world -

body - the body all other bodies are attracted toward

Method Detail

applyForce

public void applyForce(Body body)

Description copied from class: Force

applies the force to a body that is in simulation, called by the stepper functions

Specified by:

applyForce in class Force

cloneState

public UniversalGravity cloneState(ClonedReferences util)

Description copied from interface: SimState

deep clones the state object, any references to other SimState objects should be cloned and assigned to the clone via the ClonedReferences util object. The util object ensures that multiple clones of the same object are not performed during a clone operation.

Specified by:

cloneState in interface SimState

Parameters:

util - instanciate a new one if top level cloning
