Air Scan Counter

Hello,

I am trying to use the AirScan to count the amount of people who break the plane on a Video Wall. Is there a way to count up with the AirScans active count data? Id like to then feed that data into the Bar Graph output node.

Thanks for any help on this.

The Airscan node has number of active points.

Hello yes it does have the active count in the node. What I need is that for every time the active count goes to 1 or 2 that I can then add those counts together. When someone breaks the field the active count goes to 1. When they leave the field it goes back to 0. I need a node or script that will keep the count going. So that at the end of the day I know how many times the AirScan field was broken.

Hopefully that makes sense.

thank you

output to variable node: currentTouch

output to script node (if airscan total points > 0) :

if currentTouch > lastTouch
{
lastTouch = currentTouch
touchCount += 1
}

Keep in mind this will add points to your counter very rapidly if someone is just barely breaking the field, so it is not very accurate.
You could put a timeout or something in it, but that might be inaccurate in the opposite way.

So I got it working. The only thing is that it counts 1,11,111,1111,11111, etc instead of 1,2,3,4,5,6 etc.

Anyway, to correct this?

Are you using a string variable instead of an integer?
