Create a type called `world` that holds two locations. The most basic types in Typed Racket are those for primitive data, such as True and False for booleans, String for strings, and Char for characters. lang racket/gui (define-values point (get-current-mouse-state)). Find, thanks to your mouse, the coordinates where the racket has to go at each program beginning and write it in the block Go to x. ![]() VESA graphic modes are (usually) 639x479 regardless of the resolution. For instance, here is how you might define a struct called world that can hold two positions at once. The mouse position can be queried at any time with a function in a GUI context. For modes F.12 the coordinates are the same as the pixels. If you want to store two locations (one for each paddle), a list or struct is the way to go. ![]() a stream of updated mouse position coordinates events that occur every time. It's up to you to decide what to store in your world state. A user clicks on the target element, moves their mouse to move the element. Big-bang stores only one piece of information, usually called the "world state."
