;; set 4 (with a few additional things added) as a starting point.
;; We have given you some more constants, helper function called
;; touch-paddle? which you may use, and a new data defintion called Game.
;; You need to revise the program so that:
;; - the game includes a paddle that moves back and forth across the
;; bottom of the screen
;; - the paddle is controlled by the left and right arrow keys
;; - when a ball hits the paddle it disappears
;; - as before the mouse can be used to add balls to the game
;;
;; As stated above, we have given you a new data definition called Game.
;; You MUST revise the program so that it uses Game as the world state.
;; You also MUST NOT change the Game data definition in anyway (though you are
;; allowed to add more Game constants).
;;
;; We suggest you work in three distinct phases.
;; - change the program's world state to Game
;; - provide left/right arrow key control over the paddle
;; - make it so that when a ball hits the paddle it disappears
;;
;; In each of these phases you should follow the design recipes! 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, be added, and be unchanged.
