CustomNPCs Trader Commands

Trader Commands

Trader Commands is a lightweight addon for Custom NPCs that lets Trader NPCs sell command triggers instead of (or in addition to) physical items – and optionally charge real currency via Grand Economy instead of requiring players to hand over physical payment items.

Features

Command-Trigger Items

• /commanditem <name> <command...> tags your currently held item as a command trigger and renames it
• When a player buys that item from a Trader NPC, the mod runs the command server-side instead of handing over the item
• Supports a {player} placeholder, resolved to the buyer’s name
• Commands run silently – no feedback spam to ops or logs, just like a normal successful trade

Grand Economy Price Tags (optional – only active if Grand Economy is installed)

• /tradeprice <name> <price> tags a held item with a currency cost instead of a physical item price
• Trades are charged directly against the buyer’s Grand Economy balance, so currency slots can stay empty
• Works alongside command-trigger items – a single item can both cost currency and run a command on purchase
• A live tooltip on priced items shows Sufficient/Insufficient Currency in green or red based on the viewing player’s real-time balance

How it works

Trader Commands hooks into Custom NPCs’ own trade events, so it layers on top of the vanilla trader GUI without replacing it. Grand Economy is a soft dependency – the mod loads and runs fine without it, with /tradeprice and the balance tooltip simply unavailable until it’s present. Clients without Trader Commands installed can still connect to a server running it; they just won’t see the currency tooltip.

Requirements

• Minecraft 1.12.2
• Forge 14.23.5.2860 or a compatible newer 1.12.2 build
• Custom NPCs (required)
• Grand Economy (optional – enables /tradeprice and the balance tooltip)
