UpgradeFurnaces

THIS PLUGIN IS AI/VIBE CODED.

UpgradeFurnace gives your players a reason to grind — upgrade their furnaces and blast furnaces through four tiers of smelting power, each faster than the last but at the cost of burning through fuel quicker.

⚙️ Features

Four upgrade tiers — Basic, Elite, Advanced, and Ultimate, each with configurable speed multipliers, fuel multipliers, and prices Vault economy integration — upgrades cost in-game currency, fully compatible with any Vault-supported economy plugin Inventory linking — link a Chest, Double Chest, Barrel, or Shulker Box to a furnace to automatically feed fuel and raw materials in, and pull finished output back out Upgrade persistence — upgrades are stored via PDC and survive server restarts; breaking and replacing a furnace restores its previous tier Blast Furnace support — optionally allow blast furnaces to be upgraded alongside regular furnaces, toggleable in config Tier display — the furnace GUI title updates to reflect the current tier (e.g. Furnace [Ultimate]) Clean MiniMessage formatting — all messages use Kyori Adventure MiniMessage, fully customisable in config

🖱️ How to Use

Shift + Right-click a furnace or blast furnace to open the upgrade menu Shift + Left-click a furnace then a chest, barrel, or shulker box to link an inventory Shift + Left-click an already-linked furnace to unlink it

📋 Requirements

Paper 1.21.1 or later Vault + a compatible economy plugin (e.g. EssentialsX, CMI)

🔧 Configuration Everything is configurable in config.yml — tier prices, speed multipliers, fuel multipliers, blast furnace toggle, automation interval, and all plugin messages.

Built for server owners who want to give economy meaning and automation a purpose.
