Emo Framework Tutorial - Load And Drag a Sprite

I've been recently exploring this new framework. It lacks sources so im posting it here.

This example would allow you to load a sprite, and move it base on your mouse/touchdrag

 class LoadDragSprite {  
      sprite = null;  
      function onLoad() {  
      }  
      function onDispose() {  
      }  
   function handleTouch(sprite, mevent) {  
     local action = mevent.getAction();  
     if (action == MOTION_EVENT_ACTION_DOWN || action == MOTION_EVENT_ACTION_POINTER_DOWN) {  
       sprite.moveCenter(mevent.getX(), mevent.getY());  
     } else if (action == MOTION_EVENT_ACTION_MOVE) {  
       sprite.moveCenter(mevent.getX(), mevent.getY());  
     } else if (action == MOTION_EVENT_ACTION_UP ||  
           action == MOTION_EVENT_ACTION_CANCEL ||  
           action == MOTION_EVENT_ACTION_OUTSIDE ||  
           action == MOTION_EVENT_ACTION_POINTER_UP) {  
     }  
   }  
   function onMotionEvent(mevent) {  
     // pointer id is a unique id of the pointer.  
     local id = mevent.getPointerId();  
     local action = mevent.getAction();  
     if (!sprite ) {  
                sprite = emo.Sprite("graphics.png");  
                sprite.load();  
     }  
     handleTouch(sprite, mevent);  
   }  
 }
