How do should I bound a player to an area?

I was wondering when bounding a character, if my layout extents the bounds of my character then is there a way to bound the character to a certain area or should I use invisible walls?

The easiest way is set a invisible sprite with the collision box covering all the desired area, then, check if the player is overlapping this area, if not, set the Player to a specific location.

The exception can vary, like disabling the control of the player if he go out the area, or, roll him back to the area, etc.

Thankyou, I have an invisible block now keeping my player in bounds
