Wiki description

Sets the camera eye offset, and the offset that camera is looking at, for avatars that sit on the linked prim.

Caveats

• Setting this will not update the cameras of seated avatars, it will only effect avatars that subsequently sit down. The camera settings have to be prepared in advance.
• The offsets at and eye are locally relative to the prim, if you want it relative to the seated avatar (which likely has a custom sit rotation and offset) or the region, you must do the computation yourself.
  

Camera position and focus set by this function is a Prim Property. It will survive the script and it will survive prim taking and prim rezzing

<h3>Link Numbers</h3>
Each prim that makes up an [[object]] has an address, a link number. To access a specific [[prim]] in the [[object]], the [[prim]]'s link number must be known. In addition to [[prim|prims]] having link numbers, avatars seated upon the [[object]] do as well.
* If an [[object]] consists of only one [[prim]], and there are no avatars seated upon it, the ([[Link#Root_Prim|root]]) [[prim]]'s link number is zero.
* However, if the [[object]] is made up of multiple prims or there is an avatar seated upon the [[object]], the [[Link#Root_Prim|root]] [[prim]]'s link number is one.

When an avatar sits on an [[object]], it is added to the end of the link set and will have the largest link number. In addition to this, while an avatar is seated upon an object, the object is unable to link or unlink prims without [[llUnSit|unseating]] all avatars first.
<h4>Counting Prims & Avatars</h4>
There are two functions of interest when trying to find the number of prims and avatars on an object.
* <code>[[llGetNumberOfPrims]]()</code> - Returns the number of [[prim|prims]] and seated avatars.
* <code>[[llGetObjectPrimCount]]([[llGetKey]]())</code> - Returns only the number of [[prim|prims]] in the [[object]] but will return zero for attachments.

<syntaxhighlight lang="lsl2">integer GetPrimCount() { //always returns only the number of prims
    if(llGetAttached())//Is it attached?
        return llGetNumberOfPrims();//returns avatars and prims but attachments can't be sat on.
    return llGetObjectPrimCount(llGetKey());//returns only prims but won't work on attachments.
}</syntaxhighlight>See [[llGetNumberOfPrims]] for more about counting prims and avatars.

<h4>Errata</h4>
If a script located in a [[Link#Child_Prim|child]] prim erroneously attempts to access link 0, it will get or set the property of the linkset's [[Link#Root_Prim|root]] prim.  This bug ({{jira|BUG-5049}}) is preserved for broken legacy scripts. {{PBR}}
