This article discusses a technique used to make an object slide vertically, horizontally, or both while scrolling. This tutorial explains how to make an object slide in a [[Eng:scroller|scroller]]. Below is the script you will need:
{{tip|The values below are just used as an example. Adjust the values as necessary to best fit your [[Eng:project|project]].}}

<scratchblocks>
when green flag clicked
forever
  set x to ((scrollX) + (xpos))
end

when green flag clicked
forever
  repeat (100)
    change [xpos v] by (2.5)
  end
  repeat (100)
    change [xpos v] by (-2.5)
  end
end
</scratchblocks>

Placing this script into a sprite will make it move back and forth while you are scrolling.

===How it Works===
The xpos [[Eng:variable|variable]] determines how far the sprite should be offset from its original position if it were scrolling normally. This script makes it forever slide back and forth. This is similar to a Mario style platformer.
