new /obj/thing
and then set it's location and also the direction it is facing?
example: I kill a NPC and it freezes and flicks a dieing scene, then a object known as 'copse' replaces it facing the same direction, then the NPC is deleted, leaving the corpse.
Additionally, I believe there is a syntax for specifying particular values for variables that a new object can have, using braces, but I'm not sure how that works - I believe the Blue Book mentions it.
