Static Declaration

Declaration

Custom Items are declared as MetaItem objects.

You can declare them as static to references to them later.

// provide a custom identifier
new MetaItem.Builder(new Identifier("foo:custom_item")).build()

Item Registry

It is highly recommended to create a such registry to register all your items.

public class ItemRegistry {
    @Getter
    private static final Registry<MetaItem> ITEMS = new Registry<>(MetaItem.class);

    // Registry<>#register passes the MetaItem inputed to its output
    public static final MetaItem CUSTOM_ITEM = ITEMS.register(
            new MetaItem.Builder(new Identifier("foo:custom_item")).build()
    );
}

The MinecraftProject object you created can then register that ITEMS registry directly.

// create a project
MinecraftProject project = new MinecraftProject(NAME, VERSION, ID);

// register the registry and compile
project.register(ItemRegistry.getITEMS());
project.compile(...);
