rectangleSpriteNode.color = UIColor.yellowColor()
  
//set 100 width by 500 high
rectangleSpriteNode.size = CGSizeMake(100, 50)
  
//set the position of the node's centre (200 points across, 100 points up)
rectangleSpriteNode.position = CGPointMake(200, 100)
  
//add it to the screem
addChild(rectangleSpriteNode)
