Set "userCount" back to 0

[GoogleCodeExporter]

The function "context.getNumberOfUsers();" counts the number of users, who are 
standing in the sceneMap. 

If there is one person, the value of the function increases to 1. If there are 
2 people, the value turns to 2. 

The Problem: If one or both people walk outside the tracked area, the value 
doesn't go back to 0. 

Version of used library: SimpleOpenNI-0.15-osx.zip, uploaded Mar 15
What is the expected output? 0 -  What do you see instead? - 1

This is partially caused by the fact that the kinect keeps track of users that 
went off the camera field for a certain amount of time (default is 10 seconds) 
to be able to restore the user's id if this user comes back before this time is 
elapsed.
In the last version of OpenNI,NITE and avin2 Sensor Driver (Kinect Mod), you 
can specify this parameter in the GlobalDefaultsKinect.ini, change the 
parameter "ServerNoClientsTimeout" (don't forget to remove the ";" at the 
beginning of the line).

I said partially because i noticed that when a user  is not detected because 
he's too close or to far from the camera, the userLost event is actually 
dispatched and the getNumberOfUsers() change accordingly whereas when the user 
leaves the field of the camera by going to the left or right, this is when the 
user's id is kept and nothing is dispatched and getNumberOfUsers() doesn't 
change. It's not systematic but this behaviour is fairly noticeable.

Dear,

i'm using Mappinect, a sw SimpleOpenni-based. I followed your suggestion,  to 
raise timeout. Chanaged  ServerNoClientsTimeout and reinstalled the openni and 
NITE (i'm using OpenNI_NITE_Installer-OSX-0.22.zip and 
SimpleOpenNI-0.22-osx.zip). With no results. Server timeout remains 10 sec.
What am i doing wrong?

I have this same problem.
I tried to change the parameter but it still does not seem to change the 
problem. 
I cannot figure out a way to test wether the users are actually still in the 
shot being tracked or not.
Is there a function to manually reset the user count?

How many users can it track? 6?

I have the exact same issue. 

My sketch only requires and only works with 1 user. It often creates a new user 
on accident, which screws up the sketch. I'd really love a function to be able 
to either delete users or reset the user count and re-establish a single user.

Changing the ini file did not work. I am keeping track of it manually by using 
a global counter and updating it when there are SimeplOpenNi callbacks, using 
the onLostUser , onNewUser, onExitUser and onReEnterUser methods

On my mac I found the file here, works like a charm!
/usr/etc/primesense/GlobalDefaultsKinect.ini
Must edit it as root.

This is indeed causing me issues too.

Changing the kinect.ini file in windows actually is the time taken for how fast 
the onExitUser works rather than onLostUser

I just want to keep track of user 1 and if it detects anythign else to ignore 
the general openni callback methods. Im trying to use a global counter but it 
doesnt work reliably enough
