How do I use a Vast Survival Multiplayer?

The system I need is to move the player to: forward, backward, left, right with a virtual analog. And rotate left, right, up, down using the finger drag on the screen (not being virtual analog. I want it to work as if it were playing with the mouse on the pc). Anyone who can do a video tutorial, I would be very grateful and would also help me to understand the operation of the commands and the script itself. Thank you very much for your attention and have a great day / night. :)
