Hi :) I think your thread title a little bit missleading
From what I see in your picture in this thread..
Maybe you need to design all the layout area, not only defined in viewport area..
since your layout is larger than your viewport,
OR you can change the viewport size suit to layout size, or otherwise
Also you dont provide more information such as the player type, so I assume it is a Platformer as example.
Do you tried add the "Scroll to" behavior in your player character ?
