Game Boundary

We need to constrain the play area

We will create an invisible boundary

Add a new TiledBackground object

Don't give it any sprite or colour

Leave it invisible

Create the left boundary

Size: 540 x 1920

Position: -540, 0

Name the TiledBackground: Limits

Duplicate the left boundary and position it to the right:

Position: 1080, 0

Duplicate the left boundary and resize it

and reposition it at the bottom:

Size: 1080 x 380

Position: 0, 1534

The final boundary outline looks like this:

Finally, click on Limits in the Project Window

Add the Physics Behaviour

Makit it Immovable

So that we don't accidentally select or move the Limit

Set the locked property to true
