- Left

npm install curtsy --save
controller.on('frame', function(frame) {
if (frame.gestures.length) {
var gesture = frame.gestures[0];
if (gesture.type == 'circle') {
console.log('circle', direction(gesture));
//=> circle { count: 1, type: 'counter-clockwise' }
console.log(direction(gesture).type);
//=> counter-clockwise
}
}
});You can find this example in example/circle.js.
controller.on('frame', function(frame) {
if (frame.gestures.length) {
var gesture = frame.gestures[0];
if (gesture.type == 'swipe') {
console.log('swipe', direction(gesture));
//=> swipe { distance: 123.363, coordinate: 'x', type: 'right' }
console.log(direction(gesture).type);
//=> right
}
}
});You can find this example in example/swipe.js.
