How to process UI events with RAF

uievents-raf.js

var deltaX = 0, 
  queued = false; 

function myAction(){ 
  //your awesome code here uses deltaX 
  deltaX = 0; //we reset the deltaX so it can be incremented next time onEvent is executed 
  queued = false; 
} 

function onEvent(evt){ 
  if(!queued){ 
    queued = true; 
    deltaX = evt.translationX; //in the case of a pointer, if you are using a mouse you will have to do some magic with pageX or similar :) 
    requestAnimationFrame(myAction); 
  }else{ 
    deltaX += evt.translationX; 
  } 
}
