Basic Notecard Reader

Basic Notecard Reader

Introduction

Quite often i read in configuration settings from a notecard. I thought i should stick up the core part of my notecard reading script. It's not exactly rocket science but hoepfully it's useful.

The Script

<lsl> // ******************************************************************** // // Base Notecard reader // // by SimonT Quinnell // // NOTE. This treats lines starting with '#' in the notecard as a comment // // ********************************************************************

string NOTECARD = "notecard";

// ******************************************************************** // Variables // ********************************************************************

// internals for reading notecards string strNotecard; integer intLine1; key keyConfigQueryhandle; key keyConfigUUID;

   state_entry()
   {
       if (llGetInventoryType(NOTECARD) == INVENTORY_NONE)

           state main;
       }
       else
       {
           keyConfigQueryhandle = llGetNotecardLine(NOTECARD, intLine1 = 0);
           keyConfigUUID = llGetInventoryKey(NOTECARD);
