Game.prototype.loadMenu = function() {
  var game = this;
  var can = this.canvas;

  // now we can use the mouse for the menu
  can.addEventListener('click', game.menuClickEvent, false);
  can.addEventListener('touchstart', game.menuClickEvent, false);

  // draw menu
  this.loop = setInterval(function() { game.drawMenu() }, 30);
};

}

  can.removeEventListener('click', game.menuClickEvent, false);
  can.removeEventListener('touchstart', game.menuClickEvent, false);

  if (this.loop) clearInterval(this.loop);

  // ... other level init stuff

1) Adding new game object (name will be 'GO' ):   

HELLO_WORLD.ENGINE.MODULES.ACCESS_MODULE("STARTER").NEW_OBJECT("GO" ,
x , y , w , h , speed )

HELLO_WORLD.ENGINE.MODULES.ACCESS_MODULE("STARTER").NEW_OBJECT( "GO" ,
45   , 45 , 10 , 10 , 10)


// 2) Adding image or animation : 

// DRAW TYPE can be   // 'DRAW_FRAME' no animation   // 'LOOP' playing
animation  // this number '1111123123' is ID  can be any number 
//ANIMATION (  surf ,TYPE_, FrameIndex ,source , PARENT , ID , blink_
, min_ , max_ , step , speed_ , opacity_  )
HELLO_WORLD.ENGINE.MODULES.ACCESS_MODULE("STARTER").GAME_OBJECTS.ACCESS("GO").CREATE_ANIMATION(
SURF , "DRAW_FRAME" , 6 , RESOURCE.Tiles  , 1111123123 , "no" ,
1,11,1,1,1) 


3)Disable draging   GO.DRAG = false;

//  RESOURCE.NAMEOFFOLDERANIMATION

add folder "Tiles"  with images in folder /res/ and run node res.js   

// refresh page and you will get

RESOURCE.Tiles ready for use !   
// MAKE MODULE ACCESS EASY  var

STARTER = HELLO_WORLD.ENGINE.MODULES.ACCESS_MODULE("STARTER");    

STARTER.GAME_OBJECTS.ACCESS("GO").CREATE_ANIMATION( SURF ,
"DRAW_FRAME" , 6 , RESOURCE.Tiles  , 1111123123 , "no" , 1,11,1,1,1) 


//DRAG initial value is true GO.DRAG = false;
//setup quard height  =  width  GO.POSITION.DIMENSION.H = GO.POSITION.DIMENSION.W;

4) EVENTS  FOR MOUSE AND MOBILE TOUCH HANDLED
//CLICK OR TOUCH START  GO.TAP = function(){  

//this make point directing to the game object instance   
//  this.NAME or this.ANIMATION.CURRENT_FRAME   };


GO.TOUCH_DOWN = function(){  

STARTER.DESTROY_OBJECT("GO")        console.log("THIS MUST BE TERMINATED
ON MOUSE DOWN or TOUCH_DOWN  : " + this.NAME);
//this.DESTROY_ME_AFTER_X_SECUND( 100 );    //console.log("THIS MUST BE
TERMINATED ON CLICK : " + this.NAME);      };

GO.TOUCH_MOVE = function(){  
console.log("HOVER ON OBJECT OR MOBILE TOUCH_MOVE  : " + this.NAME);   };

GO.TOUCH_UP = function(){  
console.log("MOUSE UP ON OBJECT OR MOBILE TOUCH_UP  : " + this.NAME);   };*
