Body Drag System (Moved from addons section)

(If this suggestion is impossible or if I’m posting this in the wrong place, feel free to let me know).

It was quite a while ago, and I was testing an idea I had on my server. I welded a Breen water can to the head of a dead NPC/ragdoll, and then made it invisible (The invisibility actually working might tell you about how long ago it was). Picking up the can with the use key picked up the entire ragdoll itself, and I could move it around in the air slightly and drag it across the floor without using the physics gun.

I was wondering if it would be possible for an addon to do something similar to this: spawn light, invisible props (like the Breen water) on the feet (or in more appendages if performance permits) of every dead NPC (and every ragdoll, again, if performance permits).

Apparently Player:PickupObject( Entity Entity ) can be used with ragdolls, but I’m clueless as to how to turn this function into an addon.
