A hud animating involuntarily the others

Hello,
I made a very simple hud just for a choice of animations with sounds, mixing some basic scripts that I found in the forums.
It works well, but I have an unforeseen problem.
When we use the hud with my friends, and when we are near from each others, each animation launched by one animate also the others.
I suppose that it is a known problem and easily solved, but I was unable to find by searching in the forums the right answer.
So if anyone could explain me the reason or give me a link for that, it would be a great help.
Thank you in advance,
Ange

They're all listening on the same channel. Each instance would need to use a different channel to avoid "cross-talk". In a recent thread, a similar problem was addressed by selecting a channel based on a hash of the owner key. But that's overkill here because, if it's just a HUD, there's no reason it should be listening at all, but instead link_messages should be used.

(Well, actually, it probably would be better to just use llDetectedLink() in a single root-prim script instead of explicitly communicating from separate scripts in the child prims... but that may entail some aggressive overhaul of the "found scripts."

If you set the listen to filter on the Owner...

llListen(channel, "", llGetOwner(), "";

...this should fix the problem.

Caveat: The listen must be set when the object's ownership changes.

This sort of thing:

changed(integer change)
{
if (change & CHANGED_OWNER)
{
llResetScript();
}
}

A big thank you to you two. I will try to fix that.
Well, it seems that the page that I forgot to read carefully was the llListen one !
Very nice to you to spend time for help
Thanks again,
Ange
