Scrolling in a Top Down RPG

Hello. My problem I am presenting today is that which is too broad to just ask

“How do I make it scroll?”

I have made an earlier post about creating boundaries, and with the wonderful help, it was successful. You know who you are.

My problem now is I need my character to be able to roam in a map larger then whats shown on a screen.

Is there any tutorial to follow or suggestions on how to do this USING a code that is like

(NOTE the following is not code)

If your character’s x is < x of the screen, then the map will move right.

Please link any tutorials if any.
and Thank you.
