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
string NOTECARD = "notecard";
integer intLine1;
key keyConfigQueryhandle;
key keyConfigUUID;
default
{
state_entry()
{
if (llGetInventoryType(NOTECARD) == INVENTORY_NONE)
{
llSay(DEBUG_CHANNEL, "The notecard '"+NOTECARD+"' is missing!");
state main;
}
keyConfigQueryhandle = llGetNotecardLine(NOTECARD, intLine1);
keyConfigUUID = llGetInventoryKey(NOTECARD);
}
dataserver(key keyQueryId, string strData)
{
if (keyQueryId == keyConfigQueryhandle)
{
if (strData == EOF)
state main;
keyConfigQueryhandle = llGetNotecardLine(NOTECARD, ++intLine1);
strData = llStringTrim(strData, STRING_TRIM_HEAD); // Trim Whitespace; (not mandatory; if you use a space as marker you must erase this line
if (llGetSubString (strData, 0, 0) != "#") // is it a comment?
{
// OK .. now we do somthing in here with our notecard
}
}
}
}
state main
{
state_entry()
{
// rest of script execution here
}
changed(integer intChange)
{
if (intChange & CHANGED_INVENTORY)
{ // If the notecard has changed, then reload the notecard
if (keyConfigUUID != llGetInventoryKey(NOTECARD))
llResetScript();
}
}
}
