Triggered for public server resources after a player-initiated world-item drop is durably committed and published.

== Availability ==
This event is available in '''server-side''' scripts.

== Callback signature ==
<syntaxhighlight lang="lua">
onWorldItemDrop(objectId, playerId, itemKey, quantity, serverTimeMs)
</syntaxhighlight>

== Parameters ==
{| class="wikitable"
! Name !! Type !! Description
|-
| <code>objectId</code> || <code>int</code> || The positive server-assigned 64-bit ID of the published dropped item.
|-
| <code>playerId</code> || <code>int</code> || The player whose inventory supplied the dropped item.
|-
| <code>itemKey</code> || <code>string</code> || The stable inventory and world-item definition key.
|-
| <code>quantity</code> || <code>int</code> || The committed quantity removed from inventory and published in the world.
|-
| <code>serverTimeMs</code> || <code>int</code> || Server timestamp recorded when the accepted drop intent created the quarantined item.
|}

== Examples ==
Handle the event:
<syntaxhighlight lang="lua" line>
addEventHandler("onWorldItemDrop", root, function(objectId, playerId, itemKey, quantity, serverTimeMs)
outputDebugString("Player " .. playerId .. " dropped " .. quantity .. "x " .. itemKey)
end)
</syntaxhighlight>

== Notes ==
* The runtime first quarantines the new object and removes the quantity from the authoritative inventory cache. The bundled GothicRP resource persists that change before confirming the transaction.
* Only a successful durable confirmation publishes the item and emits this callback to public resources. A failed or rolled-back drop publishes no public <code>onWorldItemDrop</code> event and restores the authoritative inventory state when the session is still connected.
* The active item is broadcast reliably before public callbacks run and is then included in late-join state. This is an observation event: do not remove the inventory quantity a second time.
* Player-initiated drops emit this event instead of [[onWorldItemSpawn]].
