llMessageLinked - 20 times??

I just started to experiment with llMessageLinked, and I noticed that it sends 20 messages from one call, not just one as I would expect..
It's the exact same content, and just one call...

Can anybody please enlighten me to why?

how many prims were you sending to?

I'm sending to LINK_THIS, and it's a one prim experiment.. The single prim contains 2 notecards and 4 scripts, so I'm quite puzzled by this.

what's your code?

Simplest possible, just to experiment...

state_entry() {
string _message = "Test message";
key g_kOwner = llGetOwner();
llMessageLinked(LINK_THIS, 547845, _message, g_kOwner);
}

In the other script:

link_message(integer _sender, integer _number, string _message, key _id) {
llWhisper(0, (string) _sender);
llWhisper(0, (string) _number);
llWhisper(0, _message);
llWhisper(0, (string) _id);
}

Move the llMessageLinked() from the state_entry() to a touch_start(). You'll be able to more accurately observe what is happening as it will be responding to touches, rather than the number of times you compile.

SENDING SCRIPT:

default
{
    state_entry()
    { 
    }
    
    touch_start(integer touches)
    {
        string _message = "Test message";
        key g_kOwner = llGetOwner();
        llMessageLinked(LINK_THIS, 547845, _message, g_kOwner);
    }
}

RECEIVING SCRIPT:

default
{
    state_entry()
    {  
    }

    link_message(integer _sender, integer _number, string _message, key _id) {
    llWhisper(0, (string) _sender);
    llWhisper(0, (string) _number);
    llWhisper(0, _message);
    llWhisper(0, (string) _id);
    }  
}

OUTPUT PER TOUCH:

As Expected:

[7:39] Object whispers: 0
[7:39] Object whispers: 547845
[7:39] Object whispers: Test message
[7:39] Object whispers: 4e07f6d1-4598-4351-84fa-826ccb723ea8

So all appears to be working fine from this test.

You don't have to split them into two scripts either. But Debbie has the right idea. It was probably results from every time you compiled. Try the touch version to test your results, or manually reset your sending script once to see if it repeats multiple times, as the default state entry should only be firing once per reset (unless you are re-entering it multiple times for whatever reason).
