1.8 Hangman: "hangman.rkt"
|(require htdp/hangman)||package: htdp-lib|
The teachpack implements the callback functions for playing a Hangman game, based on a function designed by a student. The player guesses a letter and the program responds with an answer that indicates how many times, if at all, the letter occurs in the secret word.
make-word : (-> symbol? symbol? symbol? word?) reveal : (-> word? word? word?) draw-next-part : (-> symbol? true)
Chooses a “secret” three-letter word and uses the given functions to manage the Hangman game.
(hangman-list reveal-for-list draw-next-part) → true
(-> symbol? (list-of symbol?) (list-of symbol?) (list-of symbol?)) draw-next-part : (-> symbol? true)
Chooses a “secret” word—
a list of symbolic letters— and uses the given
functions to manage the Hangman game:
reveal-for-list determines how many times the chosen letter occurs
in the secret word;
draw-next-part is given the symbolic name of a body part and draws
it on a separately managed canvas.
In addition, the teachpack re-exports the entire functionality of the drawing library; see Simple Drawing: "draw.rkt" for documentation.
