I want to make the fish stay in the middle of the screen, but I want the ‘camera’ to be moving.

A great example would be the game Jetpack Joyride, the character is always in the middle, but the camera is moving.

Well, you should make everything moving but the character.

@Griffpatch also uses such a technique in his platformer games.

How would I be able to do so?

Either use a forever loop in order to periodically check if the right / left arrow is being pressed, or the event blocks:

when [ v] key pressed

So when any of the arrow keys are being pressed, you broadcast a message to your other (non-player) sprites.

Whenever these other sprites receive a broadcast message, they must move.

Put the movement code in the background, but not in the player sprite.

Hear me out, i might be wrong but you could probably just have both the background and the fish move to make it look like the camera is moving?

Try doing this

when green flag clicked
forever
go to x: (0) y: (0)
end
