RTS Selection Help

[Sumo]

So im working on this RTS game for iOS called "Medieval". I'm using an Active System Bpx box with a transparent inside so it's just a border thats able to be resized as the selection box when you click and hold the mouse button to select units. I'm trying to select units and create a small icon under the units that are selected, however with my coding its just creating numerous icons on top of each other. Normally I would use a "only one action when event loops" event, but then it messes up the troop selection for some reason. I'm using qualifiers by the way for all the troops. So at the moment my code looks like:

+ASB Box is overlapping qualifier "neutral"
-Create "selected icon" under feet of "neutral" qualifier.

How would I be able to modify my code so only one selected icon is created and the selection code works entirely. Here's my .mfa file if you could look at it, that'd be great, thanks.

Oh and for some reason the selection doesn't work when testing in mmf2, but it works (with the bug) when you run it in xcode.

Here you are!

I didn't test it with the iOS exporter, but the only foreseeable problem would be how it handles position data with the "Active System Box" object.
If it still doesn't work you can use the position of the finger and the slide delta to select the objects.

Okay thanks, that fixes the selection during mmf2 runtime, but I need a way to have the icon selection objects only create one per unit and not stack on each other. The "only one action when event loops" doesn't work with the code i have at the moment.

Ok sorry... This will do it:

This is great, thanks UrbanMonk! I just added another event to deselect the icon if the selection box wasn't overlapping the troops and it works fine. Now I can continue on with my work. Thanks again!

No problem.

I'm not sure how efficient this method is though. Destroying and creating a lot of objects every loop might cause slowdowns later, or it may not make a difference.
Later on if you have any performance issues it might be worth deactivating that event just to make sure.
