vehicle listening only to pilot

how can i make a vehicle listen only to text from the seated pilot? i want to have keyboard commands for some special function in my vehicle, such as "hatch open" and "hatch shut" or "lights on or off", so i would type "o" or "s" in the open channel, and the vehicle performs the function. This works great, unless there's TWO such vehicles, or another passenger in one vehicle, and their letters can also affect the vehicle! it's cumbersome to type in specific channel when driving around, but i lack the vocabulary to find the right bit of code to have it obey only the seated driver...

any help most appreciated!

The solution is simple: Filtering the llListen().

I suppose you must detect when an AV is sitting with a changed() event. That's the right moment to get a key... and to use it or not.

key Driver;
integer Handle;
integer Channel;

changed(integer change)
{
if (change & CHANGED_LINK)
{
Driver = llAvatarOnSitTarget();
if (Driver != NULL_KEY)
{
// An avatar just sat...
Handle = llListen(Channel, "", Driver, "";
}
else
{
// Avatar just stood up...
llListenRemove(Handle);
}
}
}

Of course, you must put a sit script in every seat and only the driver seat listens.

thanks! i'll give it a try!

in multiseat vehicles, just make sure that it checks the position of that avatar on the sittarget, is the right sit target...
