Gesture Recognition Library for Haxe

Ported from the AS3 gesture library Gestouch

Usage

OpenFL

public function new() 
{
	super();
	
	Gessie.init(stage, new OpenflInputAdapter(stage, true, true));
	Gessie.addDisplayListAdapter(DisplayObject, new OpenflDisplayListAdapter());
	Gessie.addTouchHitTester(new OpenflTouchHitTester(stage));
	
	var bmd = new BitmapData(400,400);
	var bm = new Bitmap(bmd);
	var s = new Sprite();
	s.addChild(bm);
	s.mouseEnabled = true;
	addChild(s);
	
	var tap = new TapGesture(s);
	tap.numTapsRequired = 1;
	tap.on(GERecognized, function(_) trace('tapped'));
	
	var pan = new PanGesture(s);
	pan.on(GEBegan, function(_) trace('pan began', pan._offsetX, pan._offsetY));
	pan.on(GEEnded, function(_) trace('pan ended', pan._offsetX, pan._offsetY));
	pan.on(GECancelled, function(_) trace('pan cancelled', pan._offsetX, pan._offsetY));
	pan.on(GEChanged, function(_) trace('pan changed', pan._offsetX, pan._offsetY));
	
	var swipe = new SwipeGesture(s);
	swipe.on(GERecognized, function(_) trace('swiped'));
}

Luxe

override function ready() 
{
	Gessie.init(null, new LuxeInputAdapter());
	Gessie.addDisplayListAdapter(Visual, new LuxeDisplayListAdapter());
	Gessie.addTouchHitTester(new LuxeTouchHitTester());
	
	var s = new Visual( {
		name: "test gessie",
		size: new Vector(200, 200),
	});
	
	var tap = new TapGesture(s);
	tap.numTapsRequired = 1;
	tap.on(GERecognized, function(_) trace('tapped'));
	
	var pan = new PanGesture(s);
	pan.on(GEBegan, function(_) trace('pan began', pan._offsetX, pan._offsetY));
	pan.on(GEEnded, function(_) trace('pan ended', pan._offsetX, pan._offsetY));
	pan.on(GECancelled, function(_) trace('pan cancelled', pan._offsetX, pan._offsetY));
	pan.on(GEChanged, function(_) trace('pan changed', pan._offsetX, pan._offsetY));
	
	var swipe = new SwipeGesture(s);
	swipe.on(GERecognized, function(_) trace('swiped'));
}

Heaps

override public function init() 
{
	Gessie.init(s2d, new HeapsInputAdapter(s2d));
	Gessie.addDisplayListAdapter(h2d.Sprite, new HeapsDisplayListAdapter());
	Gessie.addTouchHitTester(new HeapsTouchHitTester(s2d));
	
	var b = new h2d.Bitmap(h2d.Tile.fromColor(0xff9e67e9, 400, 400), s2d);
	
	var tap = new TapGesture(b);
	tap.numTapsRequired = 1;
	tap.on(GERecognized, function(_) trace('tapped'));
	
	var pan = new PanGesture(b);
	pan.on(GEBegan, function(_) trace('pan began', pan._offsetX, pan._offsetY));
	pan.on(GEEnded, function(_) trace('pan ended', pan._offsetX, pan._offsetY));
	pan.on(GECancelled, function(_) trace('pan cancelled', pan._offsetX, pan._offsetY));
	pan.on(GEChanged, function(_) trace('pan changed', pan._offsetX, pan._offsetY));
	
	var swipe = new SwipeGesture(b);
	swipe.on(GERecognized, function(_) trace('swiped'));
}
