Trouble with moving entity - actionscript-3

Question

I am currently trying to get acclimated to FlashDevelop, but am having trouble moving an entity, despite following tutorials very closely.
public class Main extends Engine
{
private var gameWorld:MyWorld;
public function Main()
{
super(800, 600, 60, false);
gameWorld = new MyWorld;
}
override public function init():void
{
FP.world = gameWorld;
trace("FlashPunk has started successfully!");
}
}
public class MyWorld extends World
{
private var gameEntity:MyEntity;
public function MyWorld()
{
gameEntity = new MyEntity();
add(gameEntity);
}
override public function update():void
{
//trace("MyEntity updates");
}
}
public class MyEntity extends Entity
{
[Embed(source = "dragon.png")] private const PLAYER:Class;
public function MyEntity()
{
name = "player";
graphic = new Image(PLAYER);
}
override public function update():void
{
x += 10;
y += 5;
//if (Input.check(Key.LEFT)) { x -= 5; }
//if (Input.check(Key.RIGHT)) { x += 5; }
//if (Input.check(Key.UP)) { y -= 5; }
//if (Input.check(Key.DOWN)) { y += 5; }
}
override public function added():void
{
trace("Entity added");
}
}
It is supposed to move across the screen, but does not for some reason. Any thoughts?
