Jake's Economy

[1.3.0+1.21.1] — 2026-06-29

New config fields in jakeseconomy-server.json

Note for existing servers / map-makers: These fields are fully backwards-compatible.
If your existing config file is missing any of them, the mod will automatically apply the
defaults shown below on next load. No manual editing is required unless you want to change behaviour.

GUI Tab Visibility

Control which tabs appear in the market GUI — useful for adventure maps that only want to expose certain features.

Field	Default	Description
showMarketTab	true	Show or hide the Market tab
showWithdrawTab	true	Show or hide the Withdraw tab (set false to keep all money digital)
showHistoryTab	true	Show or hide the Transaction History tab
showAuctionTab	true	Show or hide the Auction House button
allowHotkeyOpen	true	If false, the ; keybind does nothing — GUI can only be opened via /jecon market open or an NPC command

Auction Item Control

Fine-grained control over what players can list in the Auction House.

Field	Default	Description
auctionItemMode	"all"	"all" — anything not in market; "whitelist" — only listed items; "blacklist" — anything except listed items
auctionWhitelist	[]	Item IDs allowed when mode is "whitelist" (e.g. ["minecraft:bread"]). Whitelisted items bypass the market-item restriction.
auctionBlacklist	[]	Item IDs blocked when mode is "blacklist"
allowMarketItemsInAuction	false	If true, items also in the main market can be auctioned

Command Permission Levels

Each command group now has an independently configurable permission level. Set inside the "permissions" object.

Field	Default	Controls
permissions.balanceOther	2	/jecon balance <player>
permissions.give	2	/jecon give
permissions.set	2	/jecon set
permissions.take	2	/jecon take
permissions.marketOpen	0	/jecon market open (0 = all players)
permissions.marketAdmin	2	setprice, addcategory, removeprice, setlock, price
permissions.auctionOpen	0	/jecon auction open (0 = all players)
permissions.debug	2	/jecon debug

Minecraft permission levels: 0 = all players · 1 = moderator · 2 = operator · 3 = admin · 4 = owner

Config file comments

jakeseconomy-server.json now generates with inline // comments describing every field. Existing hand-edited configs still load correctly — the reader strips comments before parsing.

New features

Map-maker / server control

• GUI tab visibility — hide any tab via the config; changes sync to clients on join
• Hotkey lockdown — allowHotkeyOpen: false prevents players from opening the market with the keybind; they must interact with an NPC or use a command trigger instead
• Per-command permission levels — each admin command group has its own configurable op level; set marketOpen/auctionOpen to 2 during testing to restrict access

Auction House item filtering

• Whitelist mode — only the exact items you list in auctionWhitelist can be auctioned; the Create Listing item picker shows only those items (and correctly overrides the "market items can't be auctioned" restriction for whitelisted entries)
• Blacklist mode — block specific items from the auction house
• allowMarketItemsInAuction — opt in to allowing market items to also appear in auctions

New commands

• /jecon market open — opens the Market GUI for the executing player (permission: marketOpen)
• /jecon auction open — opens the Auction House GUI for the executing player (permission: auctionOpen)

Bug fixes

Auction House

• Fixed Create Listing item picker click targets being offset from what was displayed — draw list and click list now always use the same filtered slot array
• Fixed items outside the auction whitelist appearing in the Create Listing picker when whitelist mode was active
• Fixed OpenScreenPayload not being registered in PayloadTypeRegistry.playS2C(), causing a crash on client startup (Cannot register handler as no payload type has been registered)
• Fixed auction browse list not filtering out non-whitelisted entries when auctionItemMode is "whitelist"
