Checkers Outline

The game development process has several steps:

1. Examples: write down several examples showing different situations that will occur in the game. Make sure you consider all of the possiblities.

2. Model: decide on the model you will use for the game.

3. Draw handler. Show whose move it is as well as drawing the board.

4. Legal moves. A very important function: determine if a move is legal!

    legal-move?: Game Posn -> Boolean
   

5. Support functions: we will practice function design (including writing check-expects) to make functions we will need.

   • get-piece: (Listof Piece) Posn -> Piece: See notes for legal moves.
   • is-occupied?: (Listof Piece) Posn -> Boolean
   • take-piece: (Listof Piece) Posn -> (Listof Piece)

6. Mouse handler. The logic of interacting with the pieces can be a little complex if you want all of the details.

   • click->board-coord: Posn -> Posn: Convert from screen coordinates to the board coordinates.

7. Problem-solving tips.

   • exact-floor takes in a Real number x and puts out the greatest Integer less than or equal to x. Plain floor does the same thing, but puts out a Real.
