I'm trying to create a game that is a sort of combination of Chess & Othello. It involves chess pieces which move as they normally do, except they cannot capture, but can instead "flip" pieces as in Othello.
I can't work out how to program this in moves.
My idea is to have a macro called flipit:
(define flipit
(if (enemy? $1)
$1
(while (enemy? $1) $1)
(if (friend? $1)
back
(while (enemy? $1) $1 change-owner)
)
back
)
)
and then a slide macro:
(define slide
((verify (am-white?)) $1 (while empty?
(flipit n) (flipit e) (flipit s) (flipit w)
add $1)))
Unfortunately, what this does is that if a piece moves from A1-A4, it will do any possible flipping on each of the squares A2, A3 on the way there. |

^_^ Well, when you're calling the FlipIt Macro inside the while loops... try
(while empty? $1) back (flipit n) (flipit e) (flipit s) (flipit w) add |

Won't that only allow a piece to move as far as it possibly can? |

You know, that's true. You're going to have to find some way of only doing a single flipit for each square you do an add for... the problem you currently have is that your flipits convert eavery piece around them without committing to an actual move. Therefore, each square you travel, you build them up. Hmmm... I'm going to have to ponder a bit. If all else fails, if the board is a finite size, you can rig it by doing one for moving one, one for moving two, etc, but I'm sure you'd prefer to avoid that. |

could i set an attribute called (flipped?) or something on each piece i flip, and then have an unflipit macro that is called after the add? |

I hadn't tried it. It actually does what it's supposed to do. If it moves from a1-a4, it doesn't do the flipping for square a3. My question now is, why? |
