Non-Datapack Recipes

Not all recipes are simplistic enough or migrated to using data-driven recipes. Some subsystems still need to be patched within the codebase to provide support for adding new recipes.

Brewing Recipes

Brewing is one of the few recipes that still exist in code. Brewing recipes are added as part of a bootstrap within PotionBrewing for their containers, container recipes, and potion mixes. To expand upon the existing system, NeoForge allows brewing recipes to be added by listening to RegisterBrewingRecipesEvent.

Vanilla provides methods which take in a simple Holder<Potion> and Item to create another Holder<Potion> or two container Items to create a new container Item. NeoForge provides an implementation that takes in an input ingredient, a catalyst ingredient, and a stack output. An IBrewingRecipe instance can also be supplied for a more flexible implemenation.

IBrewingRecipe

IBrewingRecipe is a pseudo-Recipe interface that checks whether the input and catalyst is valid and provides the associated output if so. This is provided through #isInput, #isIngredient, and #getOutput respectively. The output method has access to the input and catalyst stacks to construct the result.

주의

When copying data between ItemStacks, make sure to use their respective #copy methods to create unique instances.

Anvil Recipes

Anvils are responsible for taking a damaged input and given some material or a similar input, remove some of the damage on the input result. As such, its system is not easily data-driven. However, as anvil recipes are an input with some number of materials equals some output when the user has the required experience levels, it can be modified to create a pseudo-recipe system via AnvilUpdateEvent. This takes in the input and materials and allows the modder to specify the output, experience level cost, and number of materials to use for the output. The event can also prevent any output by canceling it.

// Checks whether the left and right items are correct
// When true, sets the output, level experience cost, and material amount
public void updateAnvil(AnvilUpdateEvent event) {
if (event.getLeft().is(...) && event.getRight().is(...)) {
event.setOutput(...);
event.setCost(...);
event.setMaterialCost(...);
}
}

The update event must be attached to the NeoForge event bus.

Loom Recipes

Looms are responsible for applying a dye and pattern (either from the loom or from an item) to a banner. While the banner and the dye must be a BannerItem or DyeItem respectively, custom patterns can be created and applied in the loom. Banner Patterns can be created by registering a BannerPattern.

주의

BannerPatterns which are in the minecraft:no_item_required tag appear as an option in the loom. Patterns not in this tag must have an accompanying BannerPatternItem to be supplied via an associated tag.

private static final DeferredRegister<BannerPattern> REGISTER = DeferredRegister.create(Registries.BANNER_PATTERN, "examplemod");

// Takes in the pattern name to send over the network
public static final BannerPattern EXAMPLE_PATTERN = REGISTER.register("example_pattern", () -> new BannerPattern(
// Will look for pattern texture in assets/examplemod/textures/entity/banner/example_pattern.png
new ResourceLocation("examplemod", "example_pattern"),
// Translation key for the pattern text
"block.examplemod.banner.example_pattern"
));
