Trading Floor Ledger

Trading Floor Ledger is a lightweight addon for Create: Trading Floor that tracks how many trades each player has completed through Trading Depots and provides integration with FTB Quests and KubeJS.

Features

• Detects trades completed via Trading Depots using a Mixin.
• Tracks trade counts per player and persists them to disk.
• Works even when the player is offline.
• Fires a custom Forge event (TradingTradeEvent) that KubeJS can listen to.
• Provides the /tf_trades command to check your current trade count and progress toward the next milestone.

How It Works

Trades are attributed to the player who placed the Trading Depot. Every successful trade increases that player's recorded trade count.

The mod fires a custom Forge event called TradingTradeEvent on the Forge event bus. The event exposes:

• The player associated with the Trading Depot.
• The player's total recorded trade count.

Using KubeJS and EventJS, you can listen for this event to implement custom quests, rewards, achievements, leaderboards, or any other gameplay mechanics.

Command

/tf_trades

Displays your current trade count and progress toward the next milestone. Milestones are not built into the mod and are instead defined by your KubeJS scripts.

Requirements

• Forge 1.20.1
• Create: Trading Floor

Optional Dependencies

• KubeJS + EventJS — listen to TradingTradeEvent and implement custom logic.
• FTB Quests — integrate trade counts into quest progression.
