Passing value of Zero?

[lpearse]

Hello smart Isadora folks

I'm attempting to use Eyes++ for an installation to detect viewers so as to start video sequence, but most importantly to detect when the viewer leaves so that the sequence can return to the starting value.

I've been using Eyes++ to track objects to start the sequence, but have been unsuccessful trying to have an object count of 0 be used as a Pass Value to Trigger Value for either a jump++ actor or  a snapshot; thus far this approach isn't working. 

Is this because a value of 0 cannot be used as a trigger, but is instead the absence of value?   Might there be a better approach?

I think a comparator actor would help you.
