One thing to remember is that in Dreamcard, *most* of the main loop is
already provided in infrastructure and in the "event-driven" nature of
Dreamcard. So although you will likely implement some kind of a loop, it
will probably not be an explicit loop control structure in your code.
Of course, a lot depends on the kind of game, but often you'll have
- a start (new game) button (or menu) which gets the game started,
starts up some timers and starts the actions going
- the timers control other events, including running out of time
- button within the game to stop/abandon the play
- circumstances that you recognize as then end of the play
Then at the "end of the play" you stop all timers and actions, give (or
if it's good, store) the score, etc.
And when the user is ready to start another game - he clicks on your
So no obvious loop "around the game play".
And within the play, everything is likely to be driven by the timers or
by users actions ...
(Maybe too obvious to say this ..... look at all of the games on
RevOnline in the "Games" category, choose which one looks best to you,
and "be inspired by it" i.e. borrow the code from it.)
