Standard asset question

I have done research on this and was not able to find how to fix it.
How do I edit the standard asset - universal single joystick - to reduce joystick range of moment to avoid off screen
I want the mobile joysticks in this project to not go outside the screen. I have uploaded a video to YouTube to show what is happening. I want to reduce to overall range of the stick.


If you need the scripts please let me know. They are exactly the same as the stand assets, I have not changed them.
