So I am new to developing games, I am trying to make a mobile AR game where when the user has tapped the screen or a button, it matches a custom made level where it shows only a virtual world which is ontop of a surface. It is as if it is a pair of glasses, the button (when pressed) strips your vision of reality and puts you into a new world.
This will made for IOS if I can find out a way to put it onto my iPhone X without going through the app store, or just getting an android phone.
Can anyone tell me how I can achieve this?
