Trade and Inventory System

About this kit

Player trading with a two-step confirm and saves that cannot duplicate items, plus a stacked bag.

What you get

• Trades with Accept, a short confirm countdown, then Confirm. Any offer change resets both accepts, so nobody can swap an item at the last second.
• Every step is checked on the server: unknown items, amounts a player does not have, full bags, players who leave, spam and junk requests.
• Session-locked saves: a player's save is locked to one server at a time, so two servers never overwrite each other. Locks left by a crashed server are taken over after a set time.
• Atomic trades: both players end up with the trade or neither does, even if a server crashes between the two saves. The next join finishes or undoes the half-done trade.
• Bag with stacking: each item has its own stack size and uses one slot per stack, with a slot limit you set.
• Trade history (last 20 trades per player, saved) and a TradeKit API to give, take and count items from your own scripts.
• Mobile ready: safe-area aware screens, thumb-sized buttons, hold-to-trade prompts on players.
• Demo place Lantern Square: a part-built market plaza with two loot crates, Future lighting and post effects.
