cheap security. rezz big box if visitor not on list

I would like to set up a collision rezzer that would verify if you are on a list and if not rezz a large object in the house to make it unattractive to snoop in, If you are on the notecard list then you get a "welcome home" message and nothing happens. hmmm but then every time you touch the thing it will give the message. therefore it has to work once only if you are on the list but every time if you are not....sounding more complicated.

here is the code i use to touch rezz stuff, i just changed touch_start to collision_start which is as far as my skills go lol.

default
{
    collision_start(integer total_number)
    {
        llRezObject("ball", llGetPos() + <1, 0, 0>, ZERO_VECTOR, ZERO_ROTATION, 0);
        llSay(0, "You have no right here!");
    }

}
CODE

Uh oh. Another wrench in the gears. What if you are home and somebody else comes a-calling? Will it rez the big prim and start booting you both out?

maybe have it detect when owner is around and not do anything?

Even better would be to rez a prim big enough to fit around the avatar and have it follow them around and obscure their view.

Or work the other angle. Only rez the home when the owner is around, and hide the rezzer as a tree or something.

are you afraid someone is gonna steal your TV?

Personally I find it far more entertaining to use "More..."/"Eject & Ban"
