Duff Physics Alpha

This example was made using the following code:

public function createEngine():void
{
	midPoint = new Point();
	midPoint.x = stage.stageWidth  / 2;
	midPoint.y = stage.stageHeight / 2;
	engine = new PhysicsEngine();
	var iterator:Ball;
	var pFactor:PauliFactor;
	for( var i:int = 0; i < TOTAL_BALLS; i++ ) {
		iterator = new Ball();
		iterator.x = MathUtil.randRange( 100, 700 );
		iterator.y = MathUtil.randRange( 100, 500 );
		addChild( iterator );
 
		pFactor = new PauliFactor( iterator, i, 10 );
		pFactor.engine = engine;
		pFactor.magneticPoint = midPoint;
		pFactor.gravity = GRAVITY_STRENGTH;
		pFactor.aggression = pauliStrength;
		engine.addFactor( pFactor );
	}
	iterator = null;
	engine.addEventListener( PhysicsEvent.RENDER, updateEngine );
	engine.start();
}
 
private function updateEngine( evt:PhysicsEvent ):void
{
	var iterator:PauliFactor;
	if( FOLLOW_MOUSE ) {
		midPoint.x = mouseX;
		midPoint.y = mouseY;
	} else {
		midPoint.x = STAGE_MID_WID;
		midPoint.y = STAGE_MID_HEI;
	}
 
	graph.clear();
	graph.lineStyle( 1, 0x262626, 1 );
	graph.moveTo( engine.factors[0].x, engine.factors[0].y );
 
	for( var i:int = 0; i < engine.totalFactors; i++ ) {
		iterator = PauliFactor( engine.factors[i] );
		iterator.magneticPoint	= midPoint;
		iterator.useMagnetism	= USE_MAGNETISM;
		iterator.usePauli	= USE_PAULI;
		iterator.aggression	= pauliStrength;
		iterator.gravity	= GRAVITY_STRENGTH;
		graph.lineTo( iterator.x, iterator.y );
	}
	graph.lineTo( engine.factors[0].x, engine.factors[0].y );
}

The goal of this physics engine is to simplify common physics scenarios with ease.
I plan on converting this to Objective C once the official release is complete.
