Triggering a llDialog with a link_message?

okie so trying to make this script open a menu if it recives a llMessageLinked from another one, it gets the message but dont really pop up anything, is it possible i dont know n.n

default {
	state_entry() {
		llListen(Channel, "objectyeller", NULL_KEY, ""); // listen for dialog answers (from multiple users
	}
	 link_message(integer sender_num, integer num, string str, key id) {
		  if (str == "arow") {
			llSay (0,"recived"); //this one it gets then blah
			llDialog(llDetectedKey(0), "What do you want to do?", MENU_MAIN, Channel);
}
	} 
		listen(integer channel, string name, key id, string message) 
	{
		 if(Channel == Channel) 
		{
			if(message == "stuff")
 //more stuff 
 

The llDetected... functions only return sensible values during events that actually detect something or someone interacting with object. So llDetectedKey() in link_message returns gibberish, pretty much which is why you don't see any dialog.

If you want your dialog to be triggered through linked message, the script that displays dialog needs to somehow know who should receive it. You can probably pass the key of receiver in your link message, in the id field... or use any other means that happen to apply for your script ^^;;

I have been working a TON with passing strings between linked objects... it is pretty simple now that I have finished pounding my head against a wall to do it.

the first thing that you want to do is get the users key and pass that to the object getting the message. That way, you can have the dialog box go to the right person.

key user;
default {
	state_entry() {
		llListen(Channel, "objectyeller", NULL_KEY, ""); // listen for dialog answers (from multiple users
	}
	 link_message(integer sender_num, integer num, string str, key id) {
		  if (str == "arow") 
{
                                                user = id;
			llSay (0,"recived"); //this one it gets then blah
			llDialog(user, "What do you want to do?", MENU_MAIN, Channel);
}
	} 
		listen(integer channel, string name, key id, string message) 
	{
		 if(Channel == Channel) 
		{
			if(message == "stuff")
 //more stuff 

that should take care of the dialog box.

you also need to have the key sent to this prim
All you have to do is make sure that llDetectedKey(0) is in the id field of your llMessageLinked() tag on the prim that is sending the message


hope this helps!

You might want to put a handle on those listens :
eg

integer lkey ;

lkey = llListen ( w,x,y,z );

then later when you have processed that channel..

llListenRemove( lkey ) ;

Else if you keep returning different channels the listens are just gonna stack up and eat resource.

Just a note, the line:

llListen(Channel, "objectyeller", NULL_KEY, ""); // listen for dialog answers (from multiple users

Will listen only to objects (or by some strange twist of fate an Avatar) named "objectyeller" and therefore will not process replies from the llDialog.
