touchboom v0.2.52

touchboom

MIT-license

Reports inertial movement and key/touch/mouse events from the document. A reworking of the motion scripts found here, courtesy of Ariya Hidayat.

Try it out by visiting this page. Try clicking, dragging and releasing.

All handlers connect to the same data, so that mouse-originated glide motions continue alongside key-originated glide motions. One set of listeners are attached to the body from which all events are delegated so that behaviour may be bound many times.

Touchboom uses the legacy property event.keyCode with keyboard up, down, left, right, wasd events.

Run npm test and load the test page to see a demo.

//
// state is defined and mutated on cfg
//
let cfg = {};

//
// start coords = [ xcoord, ycoord ]
// all properties are optional
// 
cfg.coords = touchboom.coords([{
  bgn : 0
}, {
  autoweight : 10,
  bgn : 0,
  min : -400,
  max : 400
}]);

  oneventfn : function (cfg, etype, e) {
    if (etype === 'moveend') {
      // coords stopped moving
      console.log(touchboom.coordsgettotal(cfg));
    } else if (etype === 'end') {
      // mouse or finger are disengaged
      console.log(touchboom.coordsgettotal(cfg));
    }
  },
  oninertiafn : function (cfg, etype, e) {

      console.log(touchboom.coordsgettotal(cfg));
