Woah! How many "REALLY"'s is that? 
BirdByte's platformer is a great example. Here is the most common way to do it (for the character/non-terrain sprite):

when gf clicked
forever
if <key [right-arrow v] pressed?>
change [x-vel v] by (-0.2) // any negative number works
end
if <key [left-arrow v] pressed?>
change [x-vel v] by (0.2) // any positive number works
end
change [scroll-x v] by (x-vel)
set (x-vel) to ((x-vel) * (0.87))
end

the last line (set x-vel...) is to give the velocity a decreasing speed. The number could be as much as 0.99 (1 or over causes an error) or as little as 0.85. Whatever you want the range of speed to be.

Hope this helps!

I'll try it now and there are so many 'REALLY''s that i forgot how to count

It doesnt bring your sprite back to the center

You touch the edge and then you don't smoothly move back to x 0

It came out that way because i did it on my phone

Can anyone please give me a script for that?                             

              when gf clicked           
say [can anyone help] for (3) secs                    
stop script                    

I think I know what you want, is it a scrolling background, but the player can still move around and the background catches up?
