gessie

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'));
}
