Sitting problems

I have a problem with detecting when an avatar sits. I cut from the wiki changed event, and eventually pared it down to this to see if it actually detects anything.

CODE

default
{
    state_entry()
    {
    }
    
    changed(integer change)
    {
        if (change & CHANGED_LINK)
        {
            if (llAvatarOnSitTarget() != NULL_KEY)
                {
                    llOwnerSay("someone sit down?");
                 }
            else if (llAvatarOnSitTarget() == NULL_KEY)
                {
                    llOwnerSay("someone stood up?");
                 }
            else llOwnerSay("woops");
        }
      
    }

}


Whether I sit down on or stand up from the object, I always get the second message, "someone stood up?". How do I get it to detect when I actually sit down???

Thanks,
Baron

You need to set a sit target for that to work.

Oh. I started out setting the sit target, but it was set at <0,0,0>. Apparently, I never hit it. When I changed it to <0,0,.5>, that worked.

Now, though, I am trying to deal with linked prims.

Here is the problem.

I need to detect when someone sits down on the child prim. According to the wiki, the changed event does not work in a child prim. So, can I use llSitTarget in a child prim and detect the changed event from a script in the root prim? Or am I completely barking up the wrong tree????

Thanks,
Baron

I've never had a problem with using changed in a child prim. In fact, my glasses of town portal spawn portals that rely on that. Also, changed will only fire on sitting if the sit target is set to a non-ZERO_VECTOR value. So <0,0,0> will reset the sit target and stop it from firing, <0,0,0.001> will let it fire.

Well, it turns out to work well as long as the script is RUNNING. I had forgotten that I had turned it off, then wondered why it did not appear to log changed events. duh. Now it works.

Ah - a sit target of ZERO_VECTOR turns the sit target off. The Wiki appears to be very wrong... I'm off to have a look-see.
