![]() ![]() OP says that lists have not been anycodings_racket introduced in the book yet. Since the world state is now a list anycodings_racket instead of a number, the check-with anycodings_racket predicate will need to be changed: #lang racket ![]() Instead of returning a number from the anycodings_racket mouse handler, how about returning a anycodings_racket list of coordinates? Then the list of anycodings_racket coordinates can be converted to an anycodings_racket appropriate string representation before anycodings_racket calling text. I need a space between the two anycodings_racket coordinates in the same mh without throwing anycodings_racket an error. I can't think of a way to track them both anycodings_racket (ie. I'm having trouble writing the mouse-handler anycodings_racket handling the x-mouse & y-mouse in the anycodings_racket same expression. This must be done without conditionals, anycodings_racket loops, built-in functions not mentioned, anycodings_racket & etc. tells DrRacket to call mouse-expr on the current world, the current x and y coordinates of the mouse, and a MouseEvent for every (noticeable) action of the. The anycodings_racket exercise wants an animation that displays anycodings_racket the x & y coordinates on the window. I'm trying to use what has been introduced anycodings_racket in the book in a linear fashion. ![]() "Pictured Programs" anycodings_racket anycodings_racket Ch.10 (final exercise 10.2.6) is the book anycodings_racket I'm working out of. ![]()
