Link-Set detection

Just playing with old scripts and I'm trying to get the coded door script to work, everything complies except the script that tells me which button number its Link-Set number is.

Quote:
"Because of the nature of link-sets and whatnot, you'll need to edit this script to use it. You need to figure out which link number corresponds to which button. You can do this by adding a line like this to the touch_start() event, then taking it out once you've got it figured out:

llSay(0, "You touched link number " + (string)llDetectedLink(0));"

so I have this script in the button but it doesn't compile:

default

{
    state_entry()
    {
        
        llSay(0, "Hello, Avatar!");
    }

    touch_start(integer total_number)
    {
        llSay(0, "You touched link number" + (string)llDetectedLink(0));
    }
    
}

the error is "11, 69) : ERROR : Name not defined within scope" cursor is just after the last 0 (zero) can anyone tell me why please.

It needs to be llDetectedLinkNumber(). llDetectedLink() is not a LSL function

ahhh ok I have discovered I should have this in the main script, I think?

but I'm crap at this, so I get an error on this too:

default
{
state_entry()
{
queue1 = 0;
queue2 = 0;
queue3 = 0;
doClose();
}

touch_start(integer total_number)
{
        llSay(0, "You touched link number" + (string)llDetectedLinkNumber(0));
    }
      
// figure out which like was touched then translate that
// to a button value.

integer num = llList2Integer(link_trans, llDetectedLinkNumber(0));
if (num != 0 && !open)
{
llTriggerSound("click", 0.5);
enqueue(num);
checkQueue();
}
}

Error occurs just before the word integer, so i am guessing something like an { is missing?

Edit: ok changed it to llDetectedLinkNumber but still have the same error.

You need to put it inside the touch_start() event. You have it outside any event, and that gives the compiler collywobbles.

thanks, fumbled about and it works.

You can also use llGetLinkName() and name each prim appropriately. So...

default
{
   touch_start(integer nDetected)
   {
      integer primNum = llDetectedLinkNumber(0);
      llSay(0, "You touched link number "+(string)primNum+" with name '"+llGetLinkName(primNum)+"'");
   }
}

That might save you from editing the script for each new object and manually setting up a map of prim number to function.
