McAutoStore

One key stores your inventory into nearby containers. Dropped items on the ground are pulled in too — but only into a container that already holds that same item.

What it does

Store on keypress. Press . (configurable) and every item in your inventory goes into the nearest container that can take it.

Ground pickup. Items lying near you are moved into containers automatically. The rule is strict on purpose: a container must already hold that item, otherwise the item is left on the ground. Your loot never gets scattered into random chests.

What it does NOT do

Stated up front so nobody installs it expecting something else:

• No hotkey to store a single hovered item
• No search command to find where an item ended up
• No favourite / lock system for slots
• No per-container YAML rules
• No ServerSync between server and clients

If you want that full feature set, AzuAutoStore does all of it and is a mature mod.

Configuration

BepInEx/config/joaorodrigues.valheim.mcautostore.cfg

Option	Default	What it does
StoreKey	.	Key that stores your inventory
Range	12	Container search radius, in meters
OnlyMatchingContainers	true	Only store into a container that already holds that item. With false, any container with free space is used
SkipHotbar	true	Never store the first inventory row
SkipEquipped	true	Never store equipped items
IgnoredItems	Hammer,Hoe,Cultivator,SledgeStagbreaker	Prefab names that are never stored
ShowMessage	true	Show how many items were stored
PullFromGround	true	Pull dropped items into containers that already hold them
GroundRange	12	Radius scanned for dropped items, in meters
GroundScanInterval	2	Seconds between ground scans
GroundMinAgeSeconds	3	How long an item must lie on the ground first, so items you drop on purpose are not vacuumed instantly

Why it does not lose items

This is the hard part of any auto-store mod, and it is worth explaining.

A container's inventory is a local cache. The truth is a serialized blob inside the ZDO, and Container only writes that blob when you own the ZDO:

private void OnContainerChanged()
{
    if (!m_loading && IsOwner()) Save();
}

If a mod writes into a container's inventory without owning it, Save() never runs, the item exists only in local memory, and the container's CheckForChanges() — which ticks every second — reloads the blob over it. If the mod already removed the item from the player, the item is gone.

McAutoStore follows the same protocol the game itself uses in RPC_TakeAllResponse:

1. nview.ClaimOwnership() — take ownership
2. ZDOMan.instance.ForceSendZDO(...) — force the latest blob to sync
3. invalidate m_lastRevision and call Load() — re-read the real state before writing
4. only then AddItem, and only remove from the player when AddItem returned true

Step 3 is what keeps you from wiping what another player stored seconds earlier.

For ground pickup the same care applies to the item itself: ownership of the dropped item's ZDO is claimed after a matching container is found and before the drop is destroyed, so an item is never destroyed without having landed in a container first.

Multiplayer

Every player needs the mod. It works through ZDO ownership of the container, so it behaves correctly with other players around, but installing it only on the server does nothing.
