init() - Method in class simulation.engine.PhysicsApplet

invert() - Method in class simulation.engine.CollisionResult

Get a copy of this with the translation vector inverted.

invert() - Method in class simulation.engine.Vector

Invert the vector so its coordinates are negated.

isFixed() - Method in class simulation.engine.Body

Returns whether the object is fixed.

isGoing() - Method in class simulation.gui.SimulationMenu

Returns whether the simulation is currently computing a step.

isPlaying() - Method in class simulation.engine.Simulation

Tells whether this simulations is "playing."Playing generally means that the simulation is being stepped repeatedly to animate it; when it is playing, most tools (like shape adding/moving) are probably going to be off.
