Summary

Function: llAttachToAvatar( integer attach_point );
0.0 Forced Delay
10.0 Energy

Attaches the object to the avatar who has granted permission to the script. The object is taken into the users inventory and attached to attach_point.

• integer attach_point ATTACH_* constant or valid value (see the tables below)

To run this function the script must request the PERMISSION_ATTACH permission with llRequestPermissions and it must be granted by the owner. If attach_point is zero, then the object attaches to the attach point it was most recently attached to.

Caveats

Permissions
  • Do not depend upon the auto-grant status of permissions. Always use the run_time_permissions event.
  • If the script lacks the permission PERMISSION_ATTACH, the script will shout an error on DEBUG_CHANNEL and the operation fails (but the script continues to run).
  • If PERMISSION_ATTACH is granted by anyone other than the owner, then when the function is called an error will be shouted on DEBUG_CHANNEL.
  • Once the PERMISSION_ATTACH permission is granted there is no way to revoke it except from inside the script (for example, with a new llRequestPermissions call) or the script is reset or deleted.
  • Attach points can be occupied by multiple attachments.[1]
    • This was not always the case, previously if attach_point was occupied, the existing object was detached and the new attachment took it's place.
  • Objects attached to the head (and any attachment position within the head) will not be visible in First Person view (aka Mouselook) if "show attachments in mouselook" is disable.
  • If attach_point is zero but the object was never previously attached, it defaults to the right hand (ATTACH_RHAND).
  • If the object is already attached the function fails silently, regardless if the attach_point is a different attach point. -- SCR-137

Examples

<lsl>//-- rez object on ground, drop in this script, it will request permissions to attach, //-- and then attach to the left hand if permission is granted. if permission is denied, //-- then the script complains. default {

   state_entry()
   {
       llRequestPermissions( llGetOwner(), PERMISSION_ATTACH );
   }
   run_time_permissions( integer vBitPermissions )
   {
       if ( vBitPermissions & PERMISSION_ATTACH )     
           llAttachToAvatar( ATTACH_LHAND );     
       else     
           llOwnerSay( "Permission to attach denied" );
   }
   on_rez(integer rez)
   {
       if (!llGetAttached() )        //reset the script if it's not attached.
           llResetScript();      
   }
   attach(key id)
   {
       // The attach event is called on both attach and detach, but 'id' is only valid on attach
       if (id)
           llOwnerSay( "The object is attached to " + llKey2Name(id) );
       else 
           llOwnerSay( "The object is not attached");
   }

}
