class_name SimLoot
extends RefCounted
## An item lying on the ground in one [SimWorld].
##
## Ground loot does not move, so unlike bullets it needs no event stream: it
## rides the snapshot alongside enemies and is re-sent 20 times a second. That
## also means a lost packet costs nothing, which a spawn-once event could not
## claim.

## 0 means world-shared: everyone sees it, the first to reach it takes it.
## Otherwise the ONLY peer that may see or take it -- the server filters it out
## of every other snapshot, so instancing is enforced on the wire and not by
## asking the client to be polite.

## World tick it appeared, used only to decide what to evict when an instance
## somehow accumulates more loot than it should hold.

## Whether [param peer_id] is allowed to see and take this.
