How do I create a game that is usable to play on an ipad?

So I was making a game and I am really frustrated that I can only play it on a specific device.Could someone please help me with this??

Oh, so you want it to be playable on ipad is that right?
in this case use the UI interface and so that when you press on a button in the UI interface, it sends a signal to whatever you want to control and it moves it (or however you want it)

Heres an example of using buttons for mobile devices

Thankks you.This is very helpful

no problem glad I can help
