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.

Examples

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);
 
            }
        }
