InventorySwap

InventorySwap is a lightweight plugin that randomly rotates inventories between online players on a configurable timer. No databases, no bloat. Just chaos on a schedule.

Works great on SMP servers, events, or any gamemode where you want to keep players on their toes.

How it works

A countdown ticks in the action bar for every player on the server. When it hits zero, inventories rotate — armor, items, offhand included. Players get a title announcement and a sound cue. The timer resets and starts again.

Commands

All commands require the inventoryswap.admin permission.

Command	Description
/invswap interval <seconds>	Set how often the swap triggers
/invswap minplayers <n>	Minimum online players needed to swap
/invswap pause	Freeze the timer without resetting it
/invswap resume	Resume from where it left off
/invswap bypass	Toggle swap immunity for yourself
/invswap lang <en|es>	Switch between English and Spanish
/invswap reload	Reload config and restart the timer
/invswap help	Show command list in-game

Permissions

Node	Default	Description
inventoryswap.admin	OP	Full access to all commands
inventoryswap.use	Everyone	Eligible to participate in swaps
inventoryswap.bypass	Nobody	Immune to swaps entirely

Players without inventoryswap.use are silently excluded from the rotation. inventoryswap.bypass is separate — useful for staff who want to stay opt-out by default.

Configuration

# config.yml
swap-interval: 300   # seconds between each swap (default: 5 minutes)
min-players: 2       # won't swap if fewer players are online
language: en         # en | es

If there aren't enough eligible players when the timer fires, the swap is skipped silently and the timer resets normally.
