Player-to-Player Trade Mod

TradeMode

TradeMode is a server-side trading mod for Fabric that lets players safely exchange items through a shared 6×9 (54-slot) trade GUI.

How it works

• Send a request: “/trade <player>“
• The target receives clickable buttons: [Start Trade] / [Deny]
• A 5-second countdown opens the trade window
• Each player places items in their own offer area
• When both players confirm, a 3-second commit countdown completes the trade
• Any item change during countdown cancels the countdown automatically

Safety & Rules

• One active request/trade per player (prevents spam and conflicts)
• Requests expire after 60 seconds
• Closing the GUI before completion cancels the trade and returns items
• _Shift-click_ (Quick Move) is blocked to prevent bypass/duplication issues
• Before committing, the mod checks if both players can fully receive items in main inventory + hotbar

→ If not enough space, the trade does not complete (no forced drops)

Language

• “/trade language <en|kor|jp>“to set your personal language for messages.

Requirements

• Minecraft 26.1+
• Fabric Loader
• Fabric API (required)
• Server-side only (clients do not need to install the mod)
