[Opensim-users] How do you use osForceAttachToOtherAvatarFromInventory and other OSSL functions with NPC's

[Justin Clark-Casey]

Yeah, I did suggest that originally but I see now that it can't work.

All those osForceAttachment* commands assume that the receiving avatar has an inventory.  However, NPCs currently have 
no notion of inventory, so none of that stuff will work for them.

The cloning of the avatar doesn't suffer this because the code was written to avoid the inventory requirement.  The same 
could most probably be done for these force commands but it would require some non-trivial changes.  It doesn't require 
the NPC to have any notion of scene but it would require that the code operate by attaching objects directly instead of 
requesting that they are attached from an inventory item (on attaching, 'normal' avatars get an item in their inventory 
for the attachment).
