    • generateFluids

      public Stream<net.minecraft.core.Holder<net.minecraft.world.level.material.Fluid>> generateFluids()
      Description copied from class: FluidIngredient
      Returns a stream of fluids accepted by this ingredient.

      For compatibility reasons, implementations should follow the same guidelines as for custom item ingredients, i.e.:

      • Returned fluids are generally used for display purposes, and need not be exhaustive or perfectly accurate, as ingredients may additionally filter by e.g. data component values.
      • An exception is ingredients that are simple, for which it is important that this stream corresponds exactly all fluids accepted by FluidIngredient.test(FluidStack)!
      • At least one stack should always be returned, so that the ingredient is not considered empty. Empty ingredients may invalidate recipes!

      Note: no caching needs to be done by the implementation, this is already handled by FluidIngredient.fluids!

      Specified by:
      generateFluids in class FluidIngredient
      Returns:
      a stream of all fluid stacks this ingredient accepts.

      Note: No guarantees are made as to the amount of the fluid, as FluidIngredients are generally not meant to match by amount and these stacks are mostly used for display.

    • test

      public boolean test(FluidStack stack)
      Description copied from class: FluidIngredient
      Checks if a given fluid stack matches this ingredient. The stack must not be modified in any way.
      Specified by:
      test in interface Predicate<FluidStack>
      Specified by:
      test in class FluidIngredient
      Parameters:
      stack - the stack to test
      Returns:
      true if the stack matches, false otherwise

    • isSimple

      public boolean isSimple()
      Description copied from class: FluidIngredient
      Returns whether this fluid ingredient always requires direct stack testing.
      Specified by:
      isSimple in class FluidIngredient
      Returns:
      true if this ingredient ignores NBT data when matching stacks, false otherwise
