I need to make the background rise with the platforms when jumping, but I do not know how to do this. You also need the background to be drawn infinitely many times. Can you help me please

I don't think I've ever heard of excluding header files from compilation when the cpp file is using them. Neither have I found any documentation on how to do that.
