I have done attempts but I can't seem to make it work.

when green flag clicked
forever
go to x: (466) y: (-1)#
repeat until <touching [sprite 3 v] ?>
move (-10) steps
end
broadcast [message 1 v]
repeat (46)
move (-10) steps
end
hide
end

Your mistake is that you cannot move the screen in scratch.
Could you reply with the project link? I will remix it and fix the problem (there are several ways to move a screen in scratch)

Ok I will.

I mean

moving the camera is basically just moving every sprite in the opposite direction, I made a project which has a pretty small amount of code and has make you able to “move the camera” along with some comments which hopefully help explain how things work.

Thanks so much

It is so smart!

when I receive [frame v]
switch costume to [costume 2 v]
go to x: ((my x) - (x)) y: ((my y) - (y))
switch costume to [costume 1 v]
