Question Can I convert my PC game controls to work with IOS?

Hi, my old game works with a joystick or keys on a PC, but If I wanted to covert my game for use with IOS as an app on a phone how would a player control my game then?

The player has the usual up/down left/right but with four fire buttons, I suppose I'd have to make some sort of on-screen control?

I ask now because I'm using a newer version of Unity which did a brilliant job of converting my old Unity project (bar windows-10 stopping all internet connections from my game, must be that ole www module I used in my old Unity) and I've got a new iPhone so I'm going through the process of setting myself up there and seeing how things go's really, but any advice now would be a boon, thanks very much.

 

In the process of doing this the other way around (mobile to pc).

This seems to be what you are after https://docs.unity3d.com/Packages/com.unity.inputsystem@1.5/manual/OnScreen.html.

 

Thanks much apreciated.
