JFrame Woun't Rener on Panel

One way to separate your code would be, to create… :

• a HyperRushPong-Class containing the main()-method, the game-loop
  parametrization, setting up the game etc.
• a Sprite class, representing a player or a ball
• a Render class, which is a JPanel able to paint a list of Sprites
• a Game-Interface that has a animate(int time)-Method
• a OnePlayerGame class, which implements Game and KeyListener and modifies the sprites in the list
• a TwoPlayerGame class, which is the same as above, but for two players
• etc.

So you would

• create a List of Sprites
• create a Renderer and pass the list
• create a game Object and pass the list (Game game= new One(or Two)PlayerGame(sprites))
• create a JFrame
• add the Renderer
• attach the game object as KeyListener to the frame
• show the frame and call requestFocus()
• loop the game:
  o call game.animate(System.currentTimeMillis());
  o call renderer.repaint();
  o call Thread.yield();
  o call Thread.sleep(200);

Keep in mind, that there are a lot of different ways to do this and this outline might not be the best or most intuitive way of doing it, but it feels natural to me.

I’m not a big fan of Lists because 1)I find them very confusing and hard to understand, 2)I find them difficult to work with and 3)I never liked them in BlitzMax and i still don’t like them in Java. Does anyone else have any other ideas? I am looking into creating sprite, gameobject and resourcestore classes to help divide my code a bit and make it easier to read. I’m open to suggestions.
