Hi there,
   I am currently producing a game in Java. I have come across an
architecture for video games, consisting of controllers, renderers, Game
state, game simulator etc. It look a lot like a basic class diagram with
each of the parts being a class. I was planing on implementing the game
a such (i.e. having a class for game state and one for game simulator
etc) but I'm not sure if this is how games are usually designed. I does
seem to make sense to have a class for each part but I'm not sure how
they are linked together (i.e. are they all linked through the game
simulator)
I apologies for the message not being very understandable, but this is
my first move into game development and its only a basic game. What I am
looking for would be to have a look at a design/model for another game.

If there are any game developers would someone be able to help me with
this of point me the right direction. I have tried searching google but
nowhere seems to be much help.

Thanks
