Alright, so with a "When up arrow key pressed" block from the events category, you can trigger that by scrolling your mouse scroll wheel in the corresponding direction. This works with the "When down arrow key pressed" block too But how do you make a game that uses arrow keys to move, and that also uses your scroll wheel, without being able to MOVE with your scroll wheel? It turns out, that a "key up arrow pressed?" block from the sensing category DOES NOT detect your scroll wheel, so by setting up the code like inside this project, you can do one thing with your up and down arrow keys, and something completely different with your scroll wheel! Try the arrow keys and scroll wheel out on this project Scrolling works best in fullscreen so that you don't scroll the page
