So I was wondering since i know it is possible, how would you make buttons on the brain screen? Like how can you tell your screen if it’s pressing this certain range of positions do this while pressing another position do something else?

Either way, your first rectangle check is wrong: Xpos, obviously, can’t be smaller than 1 and bigger than 240 at the same time. But the rest of the code looks OK.

@eggplant @nenik So we got the buttons working so then we tried to implement a back button and the only thing i could think of doing was make it all into a switch case and the back button doesn’t work. If y’all could see the reason and explain it to me that’d be great! Here’s the code void SelectS…

[image] eggplant: That would work Is there anyway else to do it?

@abennett5139 Don’t forget to remove the int in front of StepNumber in SelectScreenSwitch and BackButton

@jpearman Is there a reason you reference/dereference pointers here rather than using a . member reference for the button struct? I’m walking through this code with some students and want to avoid broaching the topic of pointers if at all humanly possible. It compiles fine with member references, …
