Re: [racket-users] Rolling dice game
Have you taken a look at How To Design Programs? At the end of section one, you should have what you need to build these games and others like them: https://htdp.org/2019-02-24/part_one.html John Clements > On Feb 3, 2020, at 03:31, Wilzoo wrote: > > Hi guys, so I am working on rolling dice game in GUI, the game rules will be > something like rolling 3 dices and then giving out points to 2 players based > on the rolled values. > > Im now stuck on the showing value in GUI.

This is my rolling dice code: (define (nrandom n) (if (= n 0 ) '() (cons (random 1 7) (nrandom (- n 1) this is my callback function which i know is wrong: (new button% [parent gamew] [label "roll dice"] [min-width 150] ; Callback procedure for a button click: [callback (lambda (b e) (send (nrandom 3) show #t))]) So by using this im getting my 3 values in IDE window. Where should I look for information how to get them in frame in some kind of box? I just started my programming journey and racket documentation is not easy for me to get any information from there tbh. Just figuring out how to make frame and buttons + callback functions took me good few hours. (Warning: I haven't tested this code.) One thing you could do is add a new message% widget to the frame. For example, change your callback to the following: ;; button callback: (lambda (b e) ;; creating the widget has the side effect of adding it ;; to the parent container (gamew) (new message% (parent gamew) (label (format "Rolled a ~s" (nrandom 3 (void)) Adding a new widget to the game frame may change its size or layout. You can control layout with containers (see pane%, panel%, and their subclasses). But message% widgets aren't very flexible in how they display text. Another thing you could do is add a single editor canvas and write all of the die-roll messages to its editor. That would look something like this: ;; one text% and editor-canvas% per game frame: (define t (new text%)) (define ec (new editor-canvas% (parent gamew) (editor t))) ;; the button callback: ... (lambda (b e) (send t insert (format "Rolled a ~s\n" (nrandom 3))) (void)) You can refine this version by disallowing user edits (see `lock`), reliably placing the insertion point at the end of the editor before writing, adding styles to the die roll result, etc. See the text% documentation.

[racket-users] Rolling dice game
Hi guys, so I am working on rolling dice game in GUI, the game rules will be something like rolling 3 dices and then giving out points to 2 players based on the rolled values. Im now stuck on the showing value in GUI. Basically what I need is to show rolled value somewhere in frame. This is my rolling dice code: (define (nrandom n) (if (= n 0 ) '() (cons (random 1 7) (nrandom (- n 1) this is my callback function which i know is wrong: (new button% [parent gamew] [label "roll dice"] [min-width 150] ; Callback procedure for a button click: [callback (lambda (b e) (send (nrandom 3) show #t))]) So by using this im getting my 3 values in IDE window. Where should I look for information how to get them in frame in some kind of box? I just started my programming journey and racket documentation is not easy for me to get any information from there tbh. Just figuring out how to make frame and buttons + callback functions took me good few hours.
