llListen done Correctly

[LepreKhaun]

If any of you new scripters ever get confused about the correct way to keep track of listeners, you only need to study and understand https://wiki.secondlife.com/wiki/Dialog_Menus, where some of the top minds in LSL scripting have worked it out for you.

 

Pay particular attention to the section Further Listener Removal, since this covers an aspect that is often overlooked by those that have begun to think there's nothing left to learn.

I also use a toggle, to keep others from closing a listen that is

being used by the original toucher.....

 touch_start(integer num_detected)
    {
        ToucherID = llDetectedKey(0);
        if(tog == 1){llSay(0,"In Use"); }
        else
        {
        tog = 1;
        llListenRemove(listenHandle);    // It doesn't matter if we try closing an already closed, or non-existent listener  
        listenHandle = llListen(dialogChannel, "", ToucherID, "");
        llDialog(ToucherID, dialogInfo, buttons, dialogChannel);
        llSetTimerEvent(60.0); // Here we set a time limit for responses
        }
    }

 

//  then reset the toggle when the listen is closed, and in the timer

//  this allows only one user at a time, if you needed more, you could

// open a new listener and  add one to the channel after comparing

// id's ?

I like that approach, a bit friendlier than just silently locking one of the touchers out when that "game of tag" arises.
