Link message

De DigiWiki.

Triggered when the script receives a link message that was sent by a call to llMessageLinked. llMessageLinked is used to send messages from one script to another.

//This is just an example script, you shouldn't handle touches within single script this way.
 
default
{
    touch_start(integer num_detected)
    {
        llMessageLinked(LINK_THIS, 0, llDetectedName(0), llDetectedKey(0));
    }
 
    link_message(integer source, integer num, string str, key id)
    {
        // PUBLIC_CHANNEL has the integer value 0
        llWhisper(PUBLIC_CHANNEL, str + " (" + (string)id + ") touched me!");
    }
}
