Kill another object?

Ok, so I have this ball roll to the end of this marble roll type thing. When the object reaches the bottom, I have it rez another ball at the top and it keeps going. However, when the ball reaches the bottom, I need it to disappear. See the problem is that if the ball stays on the base then hundreds of balls will constantly rez depending on how long it stays there. So I need the events in this order:

1.) Ball reaches bottom
2.) One more ball is rezzed at the top
3.) Original ball disappears

This is the script I put in the base of the marble roll track.

default
{
    
    collision(integer tnum)
    {
        
            llRezObject("Marble Run Ball", llGetPos() + <0, 0, 10>, ZERO_VECTOR, ZERO_ROTATION, 42);
    }
}
}

*tries*

The easiest way I can see of doing this is edited the above script to say...

default
{
    
    collision(integer tnum)
    {
        
            llRezObject("Marble Run Ball", llGetPos() + <0, 0, 10>, ZERO_VECTOR, ZERO_ROTATION, 42);

llShout(1, "Die" );

    }
}
}

And put this script in the balls you're rezzing

default
{
    state_entry()
    {
        llListen( 1, "", "", "Die" ); 
    }

    listen( integer channel, string name, key id, string message )
    {
        llDie();

    }
}

May not be the best way of doing things, and I may have got wrong what you want to do.. But hey I gave it a shot, and I can't script

Thanks Zapoteth, works like a charm!

It may be better to filter for the the object shouting, thant the message like so (assuming shouting object is named Marble Tray):

default
{
state_entry()
{
llListen( 1, "Marble Tray", "", "" );
}
}

listen( integer channel, string name, key id, string message )
{
if(message == "Die"
llDie();

}

This way someone can't just go up to it and say Die on the right channel.

If a random bystander shouts "Die!" would it also kill the object?

Yes-- that's why you wouldn't use channel 1, but something like channel -588234. You have about 4 billion to pick from, and avatars can't send to negative channels.
