Summary
Function: integer llClearLinkMedia( integer link, integer face );| 0.0 | Forced Delay |
| 0.0 | Energy |
Clears (deletes) the media and all params from the given face on the linked prim(s).
Returns an integer that is a STATUS_* flag which details the success/failure of the operation.
| • integer | link | – | Link number (0: unlinked, 1: root prim, >1: child prims and seated avatars) or a LINK_* flag
|
|
| • integer | face | – | face number |

Caveats
- link needs to be either an actual link number or a link constants that equate to a single prim, such as LINK_ROOT and LINK_THIS.
- LINK_SET, LINK_ALL_CHILDREN and LINK_ALL_OTHERS will not work.
- The function silently fails if its face value indicates a face that does not exist.
Examples
Notes
Link Numbers
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 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 (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 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 unseating all avatars first.
Counting Prims & Avatars
There are two functions of interest when trying to find the number of prims and avatars on an object.
llGetNumberOfPrims()- Returns the number of prims and seated avatars.llGetObjectPrimCount(llGetKey())- Returns only the number of prims in the object but will return zero for attachments.
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.
}
Errata
If a script located in a child prim erroneously attempts to access link 0, it will get or set the property of the linkset's root prim. This bug (BUG-5049) is preserved for broken legacy scripts.
