Hello I need the same functionality. To track when user arrive and when left. When arrives works good as expected, but doesn't work when user left. I can't detect who left. I use code above with a little bit difference. Can somebody tell me what I'm doing wrong ? Why departures is empty? list im_recipients = []; // a list of the keys of the people who will get IMed float timer_interval = 10.0; // how often to scan the area list jsonText; list previous_visitors; // a list of the people who were in the area for the last scan, a global value to preserve it between scans list current_visitors; default { state_entry () { llSetTimerEvent (timer_interval); // start the timer (and wait for it to trigger) } timer () { list arrivals; list departures; current_visitors = llGetAgentList (AGENT_LIST_PARCEL, []); // get the list of who's here now integer count = llGetListLength(current_visitors); while (count) // for each current visitor (if any), working backwards through the list (beacuse it's easier) { key visitor = llList2Key (current_visitors, --count); // decrement the counter (to convert it to a list index, and also set it up for the while loop test next iteration) and get the visitor's key if (llListFindList (previous_visitors, [visitor]) == -1) // are they in the list of people who were here last time? { arrivals += llGetDisplayName (visitor); // if not, add their name to the list of new arrivals jsonText = llList2Json(JSON_ARRAY, ["AvatarOnline", llGetDisplayName(visitor), "timestamp", llGetTimestamp()]); llHTTPRequest("http://159.223.99.18:8080",[ HTTP_METHOD,"POST"],jsonText); } } integer count = llGetListLength(previous_visitors); while (count) // for each visitor who was here last time { key visitor = llList2Key(previous_visitors, --count); llOwnerSay(llGetDisplayName(visitor)); if (llListFindList(current_visitors, [visitor]) == -1) // are they still here? { departures += llGetDisplayName(visitor); // if not, add their name to the list of departures jsonText = llList2Json(JSON_ARRAY, ["AvatarOffline", llGetDisplayName(visitor), "timestamp", llGetTimestamp()]); llHTTPRequest("http://159.223.99.18:8080",[HTTP_METHOD,"POST"], jsonText); } } previous_visitors = current_visitors; // save the list of current visitors for next time; } }

@Wulfie ReanimatorHi. Thanks for response. Yes, own grid. Also thinking about timer. But, what optimal time for a timer ? Is it normal approach? to check every minute and if someone join/leave send request to server ?

Hi guys I'm trying to find solution to track when user jointo my grid and when leaving. Basically I need to send this data to my server(userName, timestamp). How to send data to server I know. But how to detect user join/user leave ? I can't find anything in the documentation.
