llToLower

im having a bit of trouble with my one script, i heard from someone that llToLower would allow you to use eather caps or lowercase letters and still allow you to use the command, i did this script and it dosrent respond to it atall

integer open;
default
{
    state_entry()
    {
        open = FALSE;
        llListen(0,"",llGetOwner(),"");
    }
    link_message(integer sender_num, integer num, string msg, key id)
    {
        if(msg == "open")
        {
            open = TRUE;
        }
        else if(msg == "close")
        {
            open = FALSE;
        }
    }
    listen(integer channel, string name, key id, string message)
    {
        if((llToLower(message) == "@sl") && (open == TRUE))
        {
            llLoadURL(llGetOwner(),"Go to Second Life Website.","http://www.2ndlife.com");
        }
    }
}

Thas because your open in the listen method is always FALSE.

You need to do a llListen if you want things to trigger the listen event..

See https://wiki.secondlife.com/wiki/LlListen

You are using "link_message" event...so I suppose you must have other script in the same object, sending messages to it. Can you post that script? Maybe there's the mistake.

here is the script in the other part of the object(atleast all you need rest is just coords related stuff on the top part of script and the integers)

default 
{
    state_entry() 
    {
        if (close_on_rez)
        {
            close();
        }
        else
        {
            open();
        }
    }
    
    on_rez(integer rez)
    {
        llResetScript();
        opend == FALSE;
    }
    touch_start(integer touched)
    {
        if(llDetectedKey(0) == llGetOwner()) 
        {
            if(opend == FALSE)
            {
                open();
                llMessageLinked(LINK_ROOT, 0,"open", "");
                opend = TRUE;
            }
            else if(opend == TRUE)
            {
                close();
                llMessageLinked(LINK_ROOT, 0,"close", "");
                opend = FALSE;
            }
        }
    } 
}

You still need to call llListen or the code in your 'listen' event won't ever run...

to addres the orignal question (ignoring for a moment the code presented)....

in your code, make all your commands lower case (or all uppercase if using llToUpper)
then in your listen event

listen( integer vIntChannel, string vStrSpeaker, key vKeySpeaker, string vStrHeard ){
  vStrHeard = llToLower( vStrHeard );
  if ("our command here" == vStrHeard){
    //-- do command stuff
  }
}

for even better results use
llToLower( llStringTrim( vStrHeard, STRING_TRIM ) )
to get rid of leading trailing spaces (also good for reading from notecards)

if testing for chained commands, or commands followed by a variable you can test for
if (!(llSubStringIndex( vStrHeard, "our command here" ))){ //-- test to make sure our command starts the string
or
if (~llSubStringIndex( vStrHeard, "our command here" )){ //-- test to see if our command was in the string

Ooooooohh.... oops, LINK_ROOT won't for single-prim objects, because LINK_ROOT == 1

Try 0 instead

I have seen it, I think its actually 3 prims
edit: I told you in world to reset the script....I did it with mine AFTER setting everything to its default settings and it works fine....If it still doesnt work contact me in world Mrc and I'll show you exactly what I did

i reseted the script and it didnt work for me lol ill retest it then, and voids worked
