Channel speaking to owner only

Hello

I've got a "holster" type script going on.

One object in hand
One object connected to a belt

I've created a hud that speaks on channel 88, it tells the scripts inside both objects to show or hide.

I've given this item to a few friends, but when one of us clicks show or hide on the hud, everyones items are shown or hidden.

Here is the scripts, any help is greatly appreciated!


In the object:

default
{
    state_entry()
    {
        llListen(88, "", NULL_KEY, "");
    }

    listen(integer c, string name, key id, string msg)
    {
        if (msg == "Show") llSetAlpha(0.0, ALL_SIDES);
        else if (msg == "Hide") llSetAlpha(1.0, ALL_SIDES);
    }
} 

In the HUD:

default
{

    touch_start(integer total_number)
    {
        llWhisper(88, "Show");
    }
}

^^^alternative is "hide" for the other button

In the object:

default
{
    state_entry()
    {
        llListen(88, "", NULL_KEY, "");
    }

    listen(integer c, string name, key id, string msg)
    {
        if( llGetOwnerKey( id ) == llGetOwner() )
        {
            if (msg == "Show") llSetAlpha(0.0, ALL_SIDES);
            else if (msg == "Hide") llSetAlpha(1.0, ALL_SIDES);
        }
    }
} 

Aha! So thats where llGetOwner goes...

Thank you for curing my noobism!

Generate a random integer between 10000 and 99999 ( or whatever).
Use channel 88 to let the related objects know.
use that random number as the communciation channel.

Yes, yoo might still get a duplicate once in awhile, but it is unlikely. You could code the objects to detect a duplicate, and change automatically, too.

i noteice that Cross puts the check for owner in the listen event handler.

You could also put it in the llListen(). Then the object would only hear the owner, and the check in the listen(){} would not be needed.

While this is a great idea for the general case of listening to the owner, in this case the items are listening to a HUD, so this would not work and the check in the listen event is still necessary.
