Scratch

You don't want a forever loop that keeps checking position. 

Try
[blocks]
<when green flag clicked>
<forever if> <x position> <>> 480
   <set x to( -480
<end>


<when green flag clicked>
<forever if> <x position> <<> -480
   <set x to( 480
<end>

[/blocks]

The [blocks]<forever if>[/blocks] is misleadingly named---it is really
[blocks]
<forever>
    <wait until>
[/blocks]
which avoids the busy waiting.

My way works (possibly, but I can't test it out), but everyone thinks that I can't do it at all, It is not the blocks fault that the computer goes glitchy, I might just need a new way to do it. Possibly I can see a project that has a way different to mine. Then I can download it.

<when green flag clicked>A game with my relatively simple method of running smooth continuous 1 directional scroling can be foud here:

http://scratch.mit.edu/projects/Mayhem/19961

It uses two identical sprites with a tiling background of clouds.

Sprite 1:

[blocks]
<when green flag clicked>
<go to x   -225 )y   0
<forever>
<if><( <x position> <<> -450 )>
<go to x   450 )y   0
<go back( 20 )layers>
<else>
<change x by( -5
[/blocks]

Sprite 2 is the same except that its start position is X: 225 Y:0

However, it is possible for these sprites to get out of synch, so a control method using a pair of related variables as X values might be better
