Button Touch for Android

Hey there! So I would highly recommend you follow this video tutorial. It is very good and will help a lot. https://www.youtube.com/watch?v=SrCUO46jcxk (It works on both Android and iOS)

On my Android game I then made a few panels (they were invisible) in the scene that could be viewed by the camera (it was 2D). Then I added scripts to these panels that looked kind of like this;

 public PlayerController playerController;
 
 void OnTouchDown() {
     playerController.setLeftDown(true); // Obviosuly this can be extended to more than left and right booleans
 }

I hope that this helps and if you have any questions feel free to ask!! :)
