Re-work ;; the domain analysis for changing and constant information, update the ;; data definitions, revise the main function, and so on. Make sure that ;; your tags are correct and that all your tests work correctly before you ;; proceed to the next phase. ;; ;; NOTE: Your on-tick function MUST be designed as a composition of two other ;; functions called game-with-next-balls and game-with-caught-balls. ;; ;; Note that we are giving you significant help in the starter file. ;; You absolutely MUST USE OUR STARTER AS THE BASIS FOR YOUR WORK. ;; ;; We recommend that you begin by printing this file and planning out what ;; needs to change, what needs to be added, and what will be unchanged. ;; (@problem 1) (@htdw ListOfBall) ;; Constants: (define WIDTH 605) (define HEIGHT 535) (define PADDLE-WIDTH 60) (define PADDLE-THICKNESS 10) (define PADDLE (rectangle PADDLE-WIDTH PADDLE-THICKNESS "solid" "white"))
