Gesture-Recorder

Easily create gesture patterns that you can record and save in touch based applications. Use gesture-recorder to record your gesture and get it as a string or array.Then you can use your gesture to compare with other gestures with help of Gesture.

Example

---

###Gesture-Recorder object The first step for recording gestures in your code is to instantiate Gesture-Recorder object.

var gestureRecorder = new GestureRecorder();

Then you should start record with function startRecord.

gestureRecorder.startRecord(x, y);

Next steps are adding points with addNewPoint function.

gestureRecorder.addNewPoint(x, y);

Finally, stop points recording with stopRecord

gestureRecorder.stopRecord(x, y);

After you stopped the record you can get result as string or as array.

var resultAsString = gestureRecorder.getGestureString();
var resultAsArray = gestureRecorder.getGestureArray();

#####Example

 var canvas = document.getElementById("canvas"),
        context = canvas.getContext("2d"),
        gestureRecorder = new GestureRecorder(),
        pointer = new PointerTracker(canvas);

    canvas.height = document.body.clientHeight;
    canvas.width = document.body.clientWidth;
    canvas.style.height = document.body.clientHeight + "px";
    canvas.style.width = document.body.clientWidth + "px";

    canvas.addEventListener('pointerdown', function (event) {
        gestureRecorder.startRecord(event.layerX, event.layerY);
        context.strokeStyle = 'white';
        context.lineWidth = 10;
        context.moveTo(event.layerX, event.layerY);
    }, false);

    canvas.addEventListener('pointermove', function (event) {
        gestureRecorder.addNewPoint(event.layerX, event.layerY);
        context.lineTo(event.layerX, event.layerY);
        context.stroke();
    }, false);

    canvas.addEventListener('pointerup', function (event) {
        gestureRecorder.stopRecord(event.layerX, event.layerY);
        context.lineTo(event.layerX, event.layerY);
        context.stroke();
        console.log('Gesture recorded: ' + gestureRecorder.getGestureString());
    }, false);
