One Inventory

Every player reaches into the same bag.

Pick something up and it lands in everyone's hotbar. Eat the last steak and you ate everyone's last steak. Drop something and it is gone for all of you.

For Minecraft 26.2 (Fabric).

Installing

1. Install Fabric Loader for Minecraft 26.2.
2. Put oneinventory-1.0.0.jar and Fabric API in your mods folder:
   • Windows: %appdata%\.minecraft\mods
   • macOS: ~/Library/Application Support/minecraft/mods
   • Linux: ~/.minecraft/mods

Only the server needs it. Vanilla clients can connect and play normally.

Needs at least two players. Works on an existing world.

What is shared

Everything: the hotbar, the main inventory, armour and the offhand. All forty-one slots.

The only thing still yours is which slot you happen to be holding. Two people can hold the same pickaxe at the same time, in two places, and both mine with it. Nobody has ever satisfactorily explained this and it is the best part of the mod.

Playing it

• Armour is the first fight. One set exists. Whoever equips it, everyone wears it.
• Never sort the chest while someone is fighting. Moving items around moves them for everybody, and taking the sword out of the hotbar takes it out of their hand.
• Eating is a group decision. So is drinking a potion.
• Dying scatters the shared bag. One death is everyone's loss, which does interesting things to how carefully your team plays.
• Mining works surprisingly well — two people filling one inventory twice as fast is the one genuine upside — right up until it is full.
• Bring shulker boxes. Then argue about what goes in them.

Commands

Settings

A file appears at config/oneinventory.json the first time you run the mod.

Things worth knowing

• Spectators are left out, so somebody can film.
• If two people change the same slot in the same tick, one of them wins and the other change is discarded. This is rare, and it is deliberately preferred over the alternative, which would be quietly duplicating the item.
• Your own changes apply instantly on your screen; everyone else sees them a tick later.
