Spread value and object selection, part II

[gum]

This is a sort of follow-up to a question I posted a few days ago.

I have spread an ID-value to an active object with lots of duplicates. When a duplicate is selected (when its ID matches another variable) it is supposed to do stuff. It works like this:

ID of ("Active") = Another variable --> Do stuff, Active.

It works. But. When I put "only one action when event loops" it just performs the action once, and not whenever "another variable" changes. I can sort of see why this is happening. But is there a smart way around it?

Thanks,

I think you could do:

+ID of ("Active") = Another variable
-Set Flag 0 on

+Flag 0 is on
-Do stuff
-Set flag off.

Thanks. That doesn't seem to do the trick, though. Same outcome =/

[Brandon]

Hmmm, really? Are you sure your events are ordered correctly?

[gum]

Well, I'm experimenting with the ordering right now. Subtle changes can have pretty dramatic effect, and I don't always get it =)
Maybe I'll get it to work!

[gum]

Nope. It doesn't work, no matter in what order I put the events. =/
In case you're wondering what I'm trying to do:

The active objects are floor tiles that are supposed to animate (one action when event loops) when the character walks upon them (sort of like the Billy Jean-dancefloor, you know?). Any ideas of how to achieve this?

[Brandon]

I made a quick example. Move the active around with the arrow keys and if it overlaps a dot, it changes its frame. This should help.

Thanks!

Aaaaaaaaaalmost there. Now the only problems are:

A, I don't really get the theory behind that loop stuff

But more importantly

B, You can't go from overlapping one object to another and have the first one stop animate, without first having to not overlap any of the objects. Hmm.

[Brandon]

The "theory behind that loop stuff" is that at the start of the frame every dot is given a number, starting at 0 and going to 500. A loop is always running 500 times and you compare the Alterable Value A to the LoopIndex of the loop, and that works with MMF2's built-in object selection.
