If you want scrolling, make a separate script that just sets a variable for camera X to player X and another variable for camera Y to player Y, and then any time to make a go to X and Y block make sure its X - camera X and Y - camera Y. Basically just this:

when green flag clicked
forever
set [CameraX v] to (X)
set [CameraY v] to (Y)
end

go to x: ((X) - (CameraX)) y: ((Y) - (CameraY))
