Scripting sound clip in object to a key (ala car horn via H key)

I was wondering, after doing some searching in this forum, i didnt come with anything... What I wonder is, can i attatch a sound file (say a horn) to a driving car model, and map the sound trigger to a keyboard key, say key H?

No, but you could create it as a gesture and attach it to one of the F keys.

llTakeControls() is the thing that lets us intercept key presses, and it only takes a limited number of entries as you can see.

You could attach it to the left mouse button if you're not using that.

you mean you couldn't add teh following script to a prim?

default
{
    state_entry()
    {
        llPreloadSound("CarHorn");
	llPreloadSound("Beep"); //Preload the Sound file named CarHorn (as an example)
        llListen(0, "", llGetOwner(), "");
    }

    listen(integer channel, string name, key id, string message)
    {
        integer gCmdChannel = 0;
        if (message == "h")
	llTriggerSound("CarHorn", 5.0);
        {
        else if (message == "b")
	llTriggerSound("Beep", 5.0);
        {
            //llResetScript();
        }
    }
}

seems all you need is a simple listen script, I trigger sounds on key all the time (unless that wasn't the question)

I disagree. One could certainly map a key input to triggering a sound-- it is just that we can map so few keys that there are often none available. One option would be to map a multiple key input to the trigger.

For example, I ran out of mappable keys on a plane I'd been working on awhile back, so the toggle for hover and flight modes was hitting both FWD and BACK at the same time. Worked pretty well.

why not just make a gesture?
