Hi, I'm working on a scrolling game in which will have moving platforms. I know how to make the platforms work with the scroller, but one key piece of information that I need is missing. I would like to know how I can get the platforms to move while the player is roaming and not on any of them. I know how to make a platform function vertically (y position). It's horizontally (x-position) that I'm concerned with. For example, when a player walks up to a platform, have said platform following it's path to and from point A and point B, horizontally. I cannot fathom how this can be done while the game is a scroller, being as how you have to set object's and terrain's x position to:

forever
set x to [scrollx + 480 * 0] //and add 1 for every terrain, etc.

^ with that, things only move according to it, which is why I'm confused.

Thank you for your time and I hope someone has taken the time to read this and help me! I promise to whomever helps out, you will not go un-noticed. I will look into your projects, and add a credits section to the end of the game, with your names in it!

The script

forever
set x to ((scrollx) + ((480) * (amount)))

only works with

when [right arrow v] key pressed
change [scrollx v] by (0.8)

when [left arrow v] key pressed
change [scrollx v] by (-0.8)

or similar scripts in the sprite that is "moving". This gives an illusion of movement.

I understand that. Like I know how scrollers work, but I mean I don't know how I would make a platform move on it's own in game, while also moving with the scroller. ):

***(on its x posistion, that is)

Just give the platform a

change [scrollx v] by (0.2)

or something.

If you want objects to move independently, I would guess that a

forever
set x to (((scrollx) + [offset amount]) + (independent movement))
change [independent movement v] by (2)
if <(independent movement) > [too much]> // These are for programming baddies.
point in direction (90 v) // These only work if the sprite only faces left-right.
end
if <(independent movement) < [too little]>
point in direction (-90 v)
end

would work.

Omg! Thank you so much! That's exactly what I was looking for! I will be sure to include you in the credits section of the final game! Going to go check out your projects now (: Again, thank you!
