Core Recipe Structure

InWorldRecipe

The core recipe class, implementing Recipe<InWorldRecipeContext> and IPrioritized.

Constructor Parameters

Parameter	Type	Description
icon	ItemStackTemplate	Recipe icon (displayed in JEI / recipe book)
trigger	IRecipeTrigger	Trigger condition
conflicting	List<IRecipePredicate<?>>	Conflicting predicates (consuming match; prevents other recipes after consumption)
nonConflicting	List<IRecipePredicate<?>>	Non-conflicting predicates (check only, no consumption)
outcomes	List<IRecipeOutcome<?>>	Outcome list
priority	int	Priority (lower number = higher priority), can be auto-calculated
compatible	boolean	Compatible mode (true allows multiple recipes to share inputs)
maxEfficiency	int	Maximum executions per trigger; default Integer.MAX_VALUE

Constructor Overloads

// Full constructor
new InWorldRecipe(icon, trigger, conflicting, nonConflicting, outcomes, priority, compatible, maxEfficiency);

// Omit maxEfficiency (default Integer.MAX_VALUE)
new InWorldRecipe(icon, trigger, conflicting, nonConflicting, outcomes, priority, compatible);

// Auto-calculate priority
new InWorldRecipe(icon, trigger, conflicting, nonConflicting, outcomes, compatible, maxEfficiency);
new InWorldRecipe(icon, trigger, conflicting, nonConflicting, outcomes, compatible);

Core Methods

Method	Description
matches(InWorldRecipeContext, Level)	First checks non-conflicting predicates (ShapelessMatcher.compatible), then conflicting predicates (compatible mode uses compatible, non-compatible uses incompatible). On failure, clears the predicate stack.
assemble(InWorldRecipeContext)	Pops and consumes conflicting predicates in order, executes all outcomes by probability, returns the icon ItemStack
getSerializer()	Returns LibRecipeTypes.IN_WORLD_RECIPE_SERIALIZER
getType()	Returns LibRecipeTypes.IN_WORLD_RECIPE

Automatic Priority Calculation

calcPriority(trigger, conflicting, nonConflicting, outcomes) sums the priority values of the trigger, all predicates, and all outcomes.

Serialization

InWorldRecipe.Serializer provides CODEC (MapCodec<InWorldRecipe>) and STREAM_CODEC.

JSON Fields:

Field	Type	Default	Description
icon	ItemStackTemplate	minecraft:anvil	Recipe icon
trigger	Identifier	--	Trigger registry ID
conflicting	IRecipePredicate[]	--	Conflicting predicate list
non_conflicting	IRecipePredicate[]	--	Non-conflicting predicate list
outcomes	IRecipeOutcome[]	--	Outcome list
priority	int	1	Priority
compatible	bool	true	Compatible mode
max_efficiency	int	2147483647	Max efficiency

Usage Example

InWorldRecipe recipe = new InWorldRecipe(
    new ItemStackTemplate(Items.CRAFTING_TABLE),
    trigger,
    List.of(hasItemPredicate),
    List.of(hasBlockPredicate),
    List.of(spawnItemOutcome),
    true  // compatible
);
