I made my own touch control system, and I decided to give it a test by programming it to move an arrow. Hope you like it! :D Use the on-screen D-pad to move. The center button doesn't do anything.
This touch control was created by Mr. ESE. If you want to use it yourself, all you have to do is put each control object into your backpack. If you do use this, I'll need you to put the following text in your Notes and Credits section; Touch Controls created by @Mr_ESE Original Project: https://scratch.mit.edu/projects/335808249
