dataserver

Description

Event: dataserver( key queryid, string data ){ ; }

24	Event ID
	Delay

Triggered when task receives asynchronous data

• key	queryid	–	matches the return of the requesting function
• string	data	–	the requested data (cast as a string as necessary).

Function	Input		Decode	Description
llGetNotecardLine			string	The line in the requested notecard, limited to 255 bytes. If EOF the line requested is past the end of the notecard.
llGetNumberOfNotecardLines			(integer)	The number of lines in the notecard requested.
llRequestAgentData	DATA_ONLINE	1	(integer) boolean	If the requested agent is online
	DATA_NAME	2	string	The requested agent's legacy name
	DATA_BORN	3	string	The account creation/"born on" date as a string in an ISO 8601 format of YYYY-MM-DD.
	DATA_RATING	4	llCSV2List()	Deprecated: Returns [0, 0, 0, 0, 0, 0] Used to return: [pos_behavior, neg_behavior, pos_appearance, neg_appearance, pos_building, neg_building]
	DATA_PAYINFO	8	(integer) mask	Flag			Description
				PAYMENT_INFO_ON_FILE		0x1	If payment info is on file.
				PAYMENT_INFO_USED		0x2	If payment info has been used.
llRequestInventoryData	Landmark		(vector)	The vector data received by dataserver is a global position as an offset from the current region's origin (<0,0,0>). To obtain the absolute global position of a landmark, add llGetRegionCorner() to the vector.
llRequestSimulatorData	DATA_SIM_POS	5	(vector)	The regions global position.
	DATA_SIM_STATUS	6	string	Value	Description
				"up"	region currently up and running
				"down"	region currently down
				"starting"	region currently starting
				"stopping"	region currently stopping
				"crashed"	region has crashed
				"unknown"	region status unknown or unknown region
	DATA_SIM_RATING	7	string	Value	Maturity rating
"PG"				General
"MATURE"				Moderate
"ADULT"				Adult
"UNKNOWN"				rating or region unknown

Caveats

• Dataserver answers do not necessarily come in the order they were requested.
  • If there are multiple pending requests, always use the queryid key to determine which answer is being received.
• Dataserver requests will trigger dataserver events in all scripts within the same prim where the request was made.
  • If there are multiple scripts with dataserver events in the same prim, always use the queryid key to determine which answer is being received.
  • dataserver events will not be triggered in scripts contained in other prims in the same linked object.
• If more data is requested using the same query_id before the dataserver event dealing with that query_id has resolved the data will be trashed. To avoid the trashing do not ask if(query_key == query_id). Though (see above caveats) this has its own drawbacks.

Examples

<lsl>key kQuery; integer iLine = 0; default {

   state_entry() {
       llSay(0, "Reading notecard...");
       kQuery = llGetNotecardLine("My Notecard", iLine);
   }

   dataserver(key query_id, string data) {

       if (query_id == kQuery) {
           // this is a line of our notecard
           if (data == EOF) {    

               llSay(0, "No more lines in notecard, read " + (string)iLine + " lines.");

           } else {

               // increment line count
               llSay(0, "Line " + (string)iLine + ": " + data);
               
               //request next line
               ++iLine;
               kQuery = llGetNotecardLine("My Notecard", iLine);

           }
       }
   }

}</lsl>
