Ignore me, I'm dumb

Edit: nevermind. D'oh! This script is in the root prim, so of course llSetPos moved the object.

original dumb post follows...

According to the wiki, llSetPos for child prims is local to the root prim:

http://wiki.secondlife.com/wiki/LlSetPos

Yet, when I run this code, the object is launched toward the region's 0,0,0 coordinate:

readLinkset()
{
integer nprims = llGetNumberOfPrims();
integer i;
for ( i = 0; i <= nprims; i++)
{
if ( llGetAgentSize( llGetLinkKey( i)))
{
// avatar
nprims--;
}
else
{
//not an avatar
string linkname = llGetLinkName(i);
if ( i > LINK_ROOT && llGetSubString( linkname, 0, 2) != "ref"
{
llOwnerSay(linkname);
llSetPos( < 0,0,0 >; // center prim
}
}
}
}

The name of the object is M02A-1 and the output of this code looks like this:

[13:58] M02A-1: outer ring
[13:58] M02A-1: upper
[13:58] M02A-1: lower
[13:58] M02A-1: back
[13:58] M02A-1: inner ring
[13:58] M02A-1: fl3
[13:58] M02A-1: fl4
[13:58] M02A-1: fl2
[13:58] M02A-1: fl1
[13:58] M02A-1: fd2
[13:58] M02A-1: fd1

Note that there's no output for the prim named M02A-1 (the root), so it's not being positioned. Only the child prims are. Yet, this code launches the object toward the region's 0,0,0 coordinate.

Is the wiki wrong? And did this recently change?

Hey you were smart enough to catch the error yourself. I would say that counts for something!

Ah yes. And you can't really reposition the root prim via script like you could with "Edit linked parts" in the Edit Window. Instead you have to reposition all the OTHER prims in the opposite manner (which I presume is what using "Edit linked parts" on the root prim does anyway).

Note also that if llGetNumberOfPrims() is greater than one, there IS no link at index 0. They instead start at 1. It is unfortunate that using LINK_ROOT in the library functions doesn't account for this, but it doesn't. Only use LINK_ROOT when you KNOW there is more than one prim in the link set. Kind of a worthless constant IMO.
