A tween or something else?

Hey there.

I’m trying to do a tween along the lines of this:

click here

I have the line going up the screen (not doing a pre-load, btw), but i want the line to split open into a vertical rectangular box (about 30 pixels wide) but i don’t know how to get that tween to work.

any ideas?


figured it out!
thanks, anyways.
