Following exactly what you're asking in the post above here is a capx.
I'm gonna go and take another swing at understanding this a bit better Kyatric. I think of everyone you've come the closest, but I don't have much experience with UID's or whatever they are o.9
This is what I want:
On the first collision, the first sprite goes from transparent to whatever (in this case 0)

On the second collision, the second sprite goes from transparent to whatever (in this case 1)
<img src="http://dl.dropbox.com/u/93047429/fall2.png" border="0">
On the third collision, the third sprite goes from transparent to whatever (in this case 2)
<img src="http://dl.dropbox.com/u/93047429/fall3.png" border="0">
That's what I would like. I can;t seem to figure it out :/
Yes, I need those two events in the picture you posted above NOT to be triggered at the same time. I need them to be triggered by the same CONDITION, which is the red box colliding with the green box.
There must be second condition to make them run separately, because as you say, now they are running at the same time, but I don't know what that condition is. That is what we are looking for. That's the problem.
The other problem is how to make it such that the red falling blocks keep spawning until each sprite on the right has changed frame.
For what I want in terms of what the problem is, see my quote above.
I really appreciate all the help you've given me thus far everyone. I'm learning a lot!
