vehicle script, chat command

[Doctor Visage]

hello! i am trying to make a script for vehicle which triggers an action by local chat command (on channel 0). but if its two or more same vehicles standing nearby - it will trigger them all? also if someone else says that command, they all will listen and be triggered?

how to avoid it and make it listen to only owner's chat command and only the one i am sitting in?

When you set up a listener with llListen, you're also creating an initial chat filter.

llListen(channel, name, id, msg);

If the message doesn't come from name or id, and doesn't contain msg, no listen event will happen.

If those filters pass and a listen event is triggered, you can ignore any that aren't from the owner:

if (id != llGetOwner()) return;

And you can ignore any that don't come from avatars sitting on the same object:

if (id != llAvatarOnSitTarget()) return;

if (id != llAvatarOnLinkSitTarget(link)) return;
