Eng:Making Objects Move in Scrollers

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 scroller. Below is the script you will need:

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

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

How it Works
The xpos 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.
