	Content Loss Warning!
	Due to the bug that causes VWR-12525 and VWR-6110, this function should not be used on no-copy or no-mod objects. If used on no-copy or no-mod objects the result can be content loss and client crash. Lost content can be retrieved but requires contacting Andrew Linden via IM. The fix for the bug is in the server release 1.30, slated to be rolled out on Wednesday, September 16, 2009.

Summary

1/2 Bugs

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.

Note: Constants in italic require a viewer compatible with the Project Bento skeleton.

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.

• If attach_point is occupied, the existing object will be detached and the new attachment will take it's place. Two objects cannot be attached to the same attachment point at the same time.
• 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.

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 AvatarKey)
   {
       if(AvatarKey)
       {//event is called on both attach and detach, but Key is only valid on attach
           integer test = llGetAttached();
           if (test) {
               llOwnerSay( "The object is attached" );
           } else {
               llOwnerSay( "The object is not attached");
           }
       }
   }
