💱 expTrade

Trade XP between players — give it, request it, and confirm every exchange through a chest-GUI queue.

Ever finished a mob grinder with 40 spare levels while a friend is scraping to enchant their first pickaxe? expTrade lets players hand XP back and forth like any other resource — give it, ask for it, and confirm the exchange through a clean chest-GUI queue. No dropping bottles o' enchanting on the floor, no trust games: every transfer is explicit, previewed before it happens, and time-boxed so stale offers clean themselves up.

It's fully server-side — a vanilla client can join a modded server and it just works. Runs in single-player too. No new blocks, no new items, no library mods: just /exptrade and a virtual chest menu built from vanilla items.

Why expTrade?

	expTrade
💱 Direction	Give XP away or request it — the other player always confirms
📊 Units	Whole levels, exact raw XP, or `all` — the mod does the curve math
📦 Queue	A live chest-GUI queue with per-player TTL and countdown clocks
🛡️ Safety	Personal level thresholds + re-validation at the moment of accept
🎒 Client	Server-side only — vanilla clients connect and play as normal

✨ Key features

💱 Give or request, either direction. Push your own XP to someone with give, or ask them for some with request. The other player always gets the final say.
📊 Levels or raw XP. Trade a round number of levels or an exact raw XP amount — or all to empty your bar in one go. The mod does the vanilla XP-curve math for you.
📦 A live chest-GUI queue. /exptrade pending opens a virtual chest showing every incoming offer as its own row: a clock ticking down the time left, the sender's player head, an offer/request marker, a details page, and one-click Accept / Decline buttons.
⏳ Per-player queue with TTL. Each player has their own incoming queue (default cap 10). Offers expire automatically after a timeout (default 60s), notifying both sides — nothing lingers forever.
🛡️ Threshold protection. Set a personal level floor with /exptrade threshold and the mod refuses any trade that would drop you below it — great insurance against fat-fingering give … all.
🔍 Balance preview before you commit. Every offer shows a before → after readout of both players' levels and XP, so nobody agrees blind.
🖱️ Clickable chat controls. Offers come with [View Queue], [Cancel], and (for admins) [Confirm] / [Cancel] buttons wired straight to the commands.
✅ Double-checked at execution. Amounts are validated when the offer is made and re-validated the instant it's accepted — if the giver spent their XP in the meantime, the trade fails cleanly instead of going negative.
🛠️ Admin transfers. Operators can move XP between any two online players with a two-step confirm, bypassing thresholds — handy for events, refunds, and prizes.
🔒 No item risk. The GUI slots are display-only; you can't pull items out or drop your own in. The only interactive slots are Accept and Decline.

⌨️ Commands

Everything lives under /exptrade. <player> targets are online players; amounts are positive integers, or the literal all to move your entire bar.

`/exptrade give <player> levels all`	Offer all your XP (expressed as levels)
`/exptrade give <player> exp <amount>`	Offer that many points of raw XP
`/exptrade give <player> exp all`	Offer all your raw XP

Admin commands

Require operator / gamemaster-level permission.

Command	What it does
`/exptrade admin transfer <from> <to> levels\|exp <amount>`	Stage an XP transfer between two players (bypasses thresholds)
`/exptrade admin transfer <from> <to> levels\|exp all`	Stage a transfer of all the source player's XP
`/exptrade admin confirm`	Confirm your staged transfer
`/exptrade admin cancel`	Discard your staged transfer
`/exptrade config timeout <seconds>`	Set the offer timeout (10–300s) and save

`/exptrade config reload`	Reload the config file from disk

⚙️ Configuration

Settings live in config/exptrade.json (created on first launch). Both values are also editable live in-game via /exptrade config …, which writes the file for you; /exptrade config reload re-reads it from disk.

Key	Default	Range	Meaning
`timeoutSeconds`	`60`	10–300	How long a pending offer stays in the queue before it auto-expires
`maxQueueSize`	`10`	1–50	Maximum number of pending offers a single player can have waiting at once

Per-player thresholds set with /exptrade threshold are stored separately in config/exptrade/playerdata.json and persist across restarts.
