    • getCraftingPressure

      public abstract float getCraftingPressure(net.minecraftforge.items.IItemHandler chamberHandler, it.unimi.dsi.fastutil.ints.IntList ingredientSlots)
      Returns the minimum pressure required to craft the recipe. Negative pressures are also acceptable; in this case the pressure chamber's pressure must be lower than the required pressure.
      Parameters:
      chamberHandler - what's currently in the pressure chamber
      ingredientSlots - a list of slots in chamberHandler (as returned by findIngredients(IItemHandler)) where the ingredients can be found
      Returns:
      threshold pressure

    • getCraftingPressureForDisplay

      public abstract float getCraftingPressureForDisplay()
      Get the required crafting pressure for the items specified by getInputsForDisplay(), for display purposes only (e.g. for JEI)

    • findIngredients

      public abstract it.unimi.dsi.fastutil.ints.IntCollection findIngredients(@Nonnull net.minecraftforge.items.IItemHandler chamberHandler)
      When called (by the pressure chamber BE when it detects a change in the chamber contents), try to find the ingredients for this recipe in the given item handler, which represents all the items currently in the pressure chamber. You must return a collection of slot indices into the item handler which contain the matching ingredients; those indices will be passed promptly to getCraftingPressure(IItemHandler, IntList) and craftRecipe(IItemHandler, IntList, boolean) by the pressure chamber.

      Do not cache this list across ticks, since the chamber contents are quite likely to change in the meantime.

      Parameters:
      chamberHandler - what's currently in the pressure chamber
      Returns:
      if this recipe is valid, a list of slots in the item handler where the ingredients can be found; otherwise, an empty list

    • getInputsForDisplay

      public abstract List<net.minecraft.world.item.crafting.Ingredient> getInputsForDisplay()
      Get the input items for this recipe. This is primarily intended for recipe display purposes by JEI or any other recipe display mod.

    • getSingleResultsForDisplay

      protected List<net.minecraft.world.item.ItemStack> getSingleResultsForDisplay()
      Implement if no output slots display more than one stack.
      See Also:

    • getResultsForDisplay

      public List<List<net.minecraft.world.item.ItemStack>> getResultsForDisplay()
      Get the output of this recipe, without crafting it. This is intended for recipe display purposes by JEI, Patchouli, or any other recipe display mod.

      If overriding and no output slots display more than one stack then can override getSingleResultsForDisplay() instead.

    • getSyncGroupsForDisplay

      protected List<Set<PressureChamberRecipe.RecipeSlot>> getSyncGroupsForDisplay()
      Get the slots that are synchronized with each other. They must have the same cycle length and not intersect.

      A sync group (represented by a set of PressureChamberRecipe.RecipeSlots) will have all its member's cycles synchronized should one of the members be the focus for a recipe lookup.

      If you need more functionality, see getSyncForDisplay(SlotCycle).

      Returns:
      List of sync groups represented by a set of PressureChamberRecipe.RecipeSlots

    • getSyncForDisplay

      public Map<PressureChamberRecipe.RecipeSlot,it.unimi.dsi.fastutil.ints.IntList> getSyncForDisplay(PressureChamberRecipe.SlotCycle focusedSlotCycle)
      Get the slots and associated cycles that are synchronized with the given focused slot and matched cycle indices. Prefer overriding getSyncGroupsForDisplay() unless you need special handling.

      This method is called when a recipe lookup is done through JEI that has a focus.

      Parameters:
      focusedSlotCycle - Slot and indices of the slot's cycle that matches with the focus
      Returns:
      Synchronizations for the given slot cycle

    • isValidInputItem

      public abstract boolean isValidInputItem(net.minecraft.world.item.ItemStack stack)
      Check if the given item is a valid input item for this recipe. This should also be true even if the number of items in the given item stack is smaller than the number required by the recipe; this is testing for item type, not item count.
      Parameters:
      stack - item stack to check
      Returns:
      true if this is a valid item, false otherwise

    • craftRecipe

      @Nonnull public abstract net.minecraft.core.NonNullList<net.minecraft.world.item.ItemStack> craftRecipe(@Nonnull net.minecraftforge.items.IItemHandler chamberHandler, it.unimi.dsi.fastutil.ints.IntList ingredientSlots, boolean simulate)
      This method is called when the Pressure Chamber is ready to craft with this recipe, and will only be called when findIngredients(IItemHandler) returns a non-empty list of slot numbers, i.e. the necessary items are definitely in the chamber. The implementation is responsible for removing the items that have been used from the chamberHandler. The implementation must also return the list of crafted items, for the Pressure Chamber to insert into its output item handler.
      Parameters:
      chamberHandler - items in the pressure chamber; should be modified to remove recipe input items.
      ingredientSlots - slots in the chamber handler where the ingredients can be found, as returned from findIngredients(IItemHandler)
      simulate - pass on to uses of chamberHandler
      Returns:
      the resulting items; these do not have to be copies, since the Pressure Chamber itself will insert copies of these items

    • getTooltipKey

      public String getTooltipKey(boolean input, String slotName)
      Return a translation key for a supplementary tooltip to be displayed on the ingredient or resulting item. For use in recipe display systems such as JEI (PNC's JEI integration names slots as "in{N}" and "out{N}" where n >= 0)
      Parameters:
      input - true if this is an input item, false if an output item
      slotName - a unique slot name
      Returns:
      a tooltip translation key, or "" for no tooltip
