So, I did something like this:

when gf clicked
hide
forever
 clear
 if <<key [left arrow v] pressed?> and <(scrollx) < (0)>>
  change [scrollx v] by (1) 
 end
 if <<key [right arrow v] pressed?> and <(scrollx) < (960)>> 
  change [scrollx v] by (-1) 
 end
 switch to costume [costume1 v] 
 if <(scrollx) < (-480)>
 go to x: (scrollx) y: (0)
 stamp
 end
 switch to costume [costume2 v] 
 if <<(scrollx) < (0)> and <(scrollx) > (-960)>> 
 go to x: ((scrollx) + ((480) * (1))) y: (0) 
 stamp
 end
 switch to costume [costume3 v] 
 if <(scrollx) > (-480)> 
 go to x: ((scrollx) + ((480) * (2))) y: (0) 
 stamp
 end

Is there a way to do this with velocity and still keep the wall effect at -960 and 0?

Yea, instead of changing scrollx directly, just change xvel, and then have a loop that changes scrollx by xvel

No! You don't get it! I know how to do that already! There is a wall effect at -960 and 0. Here: http://scratch.mit.edu/projects/berberberber/2660917 With velocities, the wall effect is out the window because of the decimals. I need a way to do it while keeping the wall effect.

I just downloaded and tried it, i don't know what you think the problem is, I just changed scrollx for xvel and toned down the numbers to 1 and -1 and it worked fine.

It's not a very advanced change, but ok.
Done

Like I said, the wall effect. It's not all the way there.

To fix it just add this to the end:

if <(scrollx) < (-959)>
set [scrollx v] to (959)
