Jake's Economy

[1.2.0+1.21.1] — 2026-06-08

Market GUI — Price History Graph

• Tiered snapshot system: Fine-grained 20-minute snapshots for intraday detail (Day view), hourly snapshots for long-term trends (Week / Month views)
• Graph now captures data every 20 minutes instead of every hour — Day view shows 72 points across the last 24 hours for much smoother intraday curves
• Week and Month views continue to use hourly archive data — no change in long-term resolution, storage remains efficient at ~5.4 MB for 137 items
• Tooltip hover now shows "Just now" for very recent points and properly displays minute-level timestamps
• "No data" message now shows the correct snapshot interval per view ("Data is recorded every 20 minutes" for Day, "Data is recorded hourly" for Week/Month)
• /jecon debug fillhistory test command now injects both recent (20-min intraday cycle) and archive (hourly) test data for comprehensive graph testing

Security & quality fixes

Market

• Fixed duplicate achievement lock check in sell() — now uses the extracted helper method isAchievementLocked()
• Fixed pre-existing code quality warnings (redundant cast, dangling Javadoc)

Auction House

• Fixed expired BIN listings being purchasable between tick-loop scans (up to 1-second window) — instantBuy() now checks expiry before allowing purchase
• Fixed full bid history being serialized and sent over the network to every client — only top bid data is transmitted now (bandwidth optimization)
• Fixed control characters in modded item names or player profile names breaking auction JSON — all user-visible strings now use full JSON escaping
• Fixed minBidIncrementPercent config field not being read; minimum bid increment is now correctly driven by the configured value instead of always using 1 %
• Sellers who cancel a listing while offline now receive a chat notification on next login (mirrors the existing outbid / auction-ended offline notification system)
• Fixed missing balance sync in placeBid and instantBuy — buyer's HUD balance now updates immediately after funds are deducted
• Fixed confusing "Items delivered to your inventory" message showing even when no items fit in the player's inventory

Save data

• AuctionState.load() visibility lowered to package-private — external callers must use safeLoad() which includes corruption recovery
• All three event schedulers (AuctionExpireScheduler, TrendSnapshotScheduler, PriceDecayScheduler) now guard against double-registration on world reload
• applyDecay() no longer calls setDirty() twice per tick when changes are made

Commands

• Main command root renamed from /jakeseconomy to /jecon (shorter alias used everywhere)
• Added /balance player shortcut — shows abbreviated + exact balance; only registers if no competing mod claims the literal /balance command
• Fixed /jecon take not syncing the updated balance to the target player's client HUD when the player is online

Market GUI

• Balance label now shows an exact-value tooltip on hover

Economy API (com.github.devjake123.jakeseconomy.api)

• New JakesEconomyApi.hasEnoughBalance(uuid, amount, server) — null-safe check without callers needing to read and compare manually
• New JakesEconomyApi.transferBalance(from, to, amount, server) — atomic player-to-player transfer; returns false on insufficient funds
• New JakesEconomyApi.isMarketItem(itemId, server) — returns true if the item is listed in the active price config
• New JakesEconomyApi.getMarketPrice(itemId, server) — returns current live price or -1 if not listed
• New JakesEconomyApi.syncBalance(uuid, server) — explicit manual client-HUD sync (write methods already call this automatically)
• All API write methods (deposit, withdraw, setBalance, transferBalance) now automatically sync the updated balance to the player's client if they are online
• Fixed BALANCE_CHANGED event firing twice per deposit/withdraw call
• New EconomyApiEvents.AUCTION_BID_PLACED event — fires when a bid is accepted; payload: auctionId, bidderId, bidAmount, antiSniped
• New EconomyApiEvents.AUCTION_CANCELLED event — fires when a seller cancels a listing; payload: auctionId, sellerId, itemId
