This tutorial explains how to make an object move in a scroller.
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. Below is the script that is needed:
when green flag clicked forever ... go to x: ((scrollX) + (xpos)) y: ((scrollY) + (ypos)) ... end
If a large costume is selected, it can be made to hide when it's touching the edge by adding this to the forever loop:
... if <<([abs v] of ((scrollX) + (xpos))) > (240)> or <([abs v] of ((scrollY) + (ypos))) > (180)>> then hide ... else show ... end ...
The following script will change the 'x pos' relative to the entire scrolling.
when green flag clicked
forever
repeat (100)
change [xpos v] by (2.5)
end
repeat (100)
change [xpos v] by (-2.5)
end
end
