The Curse of The Pharaoh

This project is a MUD (multi-user dungeon) built using Racket, a multi-paradigm programming language based on the Scheme dialect of Lisp. This was made in homage to the old MUD games, as a fun way to learn functional programming.

(define (change-situation n)(set! situation n))

  • change-direction: Change Marco's direction when traveling.

(define (change-direction n)(if (and (> food 0) (member? 'freeman status))

(begin(remove-from-inventory 'food)(set! food (- food 1))

(cond [(= n 1) (travel-north)]

[(= n 2) (travel-south)]

[(= n 3) (travel-east)]

[(= n 4) (travel-west)]

[(= n 5) (the-minor-quest)]

[(= n 6) (the-major-quest)]

[#t (set! actual-place 5)]))(printf "Not enough food to travel")))

  • take-hit: When a enemy attack you, you either lose armor points or die if you have no armor.

(define (take-hit n)(if(eq? armor 0)(begin(set! armor (- armor n))(set! wounds (+ wounds n))(printf "You felt your armor saved your life this time,but you're wounded...maybe it's time to flee")) (begin (change-situation 0)(printf "This blow was fatal. You're dead. GAME OVER\n\n\n\n")(menu))))

  • debt: This function debts the item price from your gold, and add the specified item in your inventory.If Marco have not enough money, the player is warned.
