Touch Zoom

[Dan335]

Anyone have info about multi-touch?  I can't find much.  I'm trying to do pinch zoom.

It looks like I should use event.data.originalEvent.changedTouches but it seems to only have one touch at a time and the identifier is always 1.  event.data.originalEvent.touches is always empty.

@Dan335 try using:  e.data.originalEvent.targetTouches

I did it this way with hammerjs

 

this.hammer = new Hammer.Manager(this.canvas);
const pinch = new Hammer.Pinch();
this.hammer.add([pinch]);
this.hammer.on('pinchmove', (event) => {
  mainCamera.zoom = (mainCamera.zoom * 0.9 + mainCamera.zoom * event.scale * 0.1);
});
