The ‘animate’ function won’t let you produce a program that interprets keystrokes. You will need to use big-bang, if you wish to use 2htdp/universe. If you are a beginner, I urge you to visit http://www.ccs.neu.edu/home/matthias/HtDP2e <http://www.ccs.neu.edu/home/matthias/HtDP2e> and study Part I. If you just want Racket code, visit the documentation on windowing at https://docs.racket-lang.org/gui/index.html?q=key%20event <https://docs.racket-lang.org/gui/index.html?q=key%20event> -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
