Count number of skeletons / multiple skeleton handling

[Jet]

Anyone know how to count the number of skeletons are active? or dump
all active skeletons into an array?

I'm trying out an AR installation that overlays the skeleton with
random movieclips (hats, clothes, goggles, etc.)... The main problem
I'm having is if there are more than 1 skeleton detected, the
overlayed items jitter and jump between the detected skeletons.

I was thinking of dumping all active skeletons in an array
(skeletonArray) and just access skeletonArray[0] as the "active"
skeleton and ignore the rest. I have no idea how to do this though

Has anyone encountered this problem before?

Awesome work btw. Thanks in advance!
