I discovered a way to scroll using ur scroll wheel by using the if pressing up hat block thing, it detects scrolls, but it detects arrow keys also, so to make it so arrow keys dont interfere, an if pressing up arrow key boolean, it doesnt detect scrolls, so you can put it in the hat block so it only detects scrolls, also works fore down arrow key too
go into fullscreen for better smoothness. use this in your projects! maybe a little credit if you do but its optional
