This section contains expressions that start the Chat Noir game going.

First, here is a function to compute state of the world at the start of a game.

<initial-world> ::=

> (define board-size 11)
> (define (make-initial-world)
> (define initial-board
> (add-n-random-blocked-cells
> 6
> (empty-board board-size)
> board-size))
> (make-world initial-board
> (make-posn (quotient board-size 2)
> (quotient board-size 2))
> 'playing
> board-size
> #f
> #f))

Finally, we can define and provide a function to start the game by calling big-bang with the appropriate arguments.

<go> ::=

> (provide main)
> (define (main)
> (void
> (big-bang (make-initial-world)
> (on-draw render-world
> (world-width board-size)
> (world-height board-size))
> (on-key change)
> (on-release release)
> (on-mouse clack)
> (name "Chat Noir"))))
