CoolCatLib: Core

v2100.2.0.1 Release | Oct 4, 2026

✨ New Features

• Item decorators: custom drawing over an item wherever the game draws it in a GUI (inventory slots, the hotbar, a held stack), after vanilla's durability bar, cooldown and count, the same on every loader. Implement api.item.DecoratedItem on the item's class and hand over its api.client.gui.ItemDecorator in registerDecorators(registrar): that's all, Core registers it by itself, on the client, the first time the item is drawn. An item's own isBarVisible still decides whether vanilla's bar shows under it.
