Confine Movement or Die if Object Moves Beyond Point or Parcel

I'v got a desert-themed skybox that could really use a tumbleweed or two. I've got a sphere that gets pushed around by the wind, but could someone push me in the right direction?

I'd like to add a script that confines the tumbleweed to the skybox, either by limiting it's movement or by dying if it moves beyond a certain point.

Thanks!

I'll follow these leads and see where they take me.

I recently did this with a bull ride script. The only difference is the bull resets to its start position instead of dying. I use a prim to set my boundary. I drop a script in the boundary prim and get its bounding box, then it sends that to my bull so it knows what its boundaries are. If I need a large boundary I use a megaprim to set it. After you get the boundary you no longer need the boundary prim since the bull script knows what the boundary is.

Get boundary script - used in a temporary prim sized as your boundary

From: someone

// Boundary getter script
// Get the boundary from the prim. If I need a large boundary I use a megaprim or a linkset of prims, which are counted as a whole bounding box

list temp_list = llGetBoundingBox(llGetKey());

loc = llGetPos();
min = loc + llList2Vector(temp_list,0);
max = loc + llList2Vector(temp_list,1);


Test boundary script - Used in your moving object to test the known boundary (determined by the above script)
From: someone

// Boundary test using current location of object
// Checks x, y and z
vector current_pos = llGetPos();
if ( current_pos.x >= min.x && current_pos.x <= max.x &&
current_pos.y >= min.y && current_pos.y <= max.y && current_pos.z >= min.z && current_pos.z <= max.z)
{
// Yes, within boundary
}
else
{
// No, outside boundary
}

Sweet. I have been looking for a solution like this for some radio controlled ducks I made a while ago. The difference being I'd like the duck to turn towards the center point and be given a nudge in the right direction when it hits boundary.

Shouldn't be too hard to work that in :-)
