Categories

MarketCategory enum and material mapping — axes are weapons, not tools.

Compatible with: GrzybcioRynek 1.0.3Minecraft 26.2Web 0.1.0

Based on GrzybcioRynek 1.0.3 and web 0.1.0 source.

Categories are the enum com.example.marketplace.inventory.MarketCategory. Filtering runs server-side in matches(MarketListing). Button icons and slots live in gui.yml → browse.categories and are used by MarketCategoryGUI.

You cannot add a new category with YAML alone — you must add an enum value and a matches rule. Guide: Developer → Add a category.

What you can change in YAML

Button slot and material in MarketCategoryGUI. Names: messages.gui.category.*.

You cannot change classification rules without editing MarketCategory.java. You cannot add a 13th category with gui.yml alone — an unknown key does not become an enum.
