Method Detail

insertItem

@Nonnull
public static ItemStack insertItem(IItemHandler dest,
                                            @Nonnull
                                            ItemStack stack,
                                            boolean simulate)

canItemStacksStack

public static boolean canItemStacksStack(@Nonnull
                                         ItemStack a,
                                         @Nonnull
                                         ItemStack b)

canItemStacksStackRelaxed

public static boolean canItemStacksStackRelaxed(@Nonnull
                                                ItemStack a,
                                                @Nonnull
                                                ItemStack b)

A relaxed version of canItemStacksStack that stacks itemstacks with different metadata if they don't have subtypes. This usually only applies when players pick up items.

copyStackWithSize

@Nonnull
public static ItemStack copyStackWithSize(@Nonnull
                                                   ItemStack itemStack,
                                                   int size)

insertItemStacked

@Nonnull
public static ItemStack insertItemStacked(IItemHandler inventory,
                                                   @Nonnull
                                                   ItemStack stack,
                                                   boolean simulate)

Inserts the ItemStack into the inventory, filling up already present stacks first. This is equivalent to the behaviour of a player picking up an item. Note: This function stacks items without subtypes with different metadata together.

giveItemToPlayer

public static void giveItemToPlayer(PlayerEntity player,
                                    @Nonnull
                                    ItemStack stack)

giveItemToPlayer without preferred slot

giveItemToPlayer

public static void giveItemToPlayer(PlayerEntity player,
                                    @Nonnull
                                    ItemStack stack,
                                    int preferredSlot)

Inserts the given itemstack into the players inventory. If the inventory can't hold it, the item will be dropped in the world at the players position.

Parameters:

player - The player to give the item to

stack - The itemstack to insert

calcRedstoneFromInventory

public static int calcRedstoneFromInventory(@Nullable
                                            IItemHandler inv)

This method uses the standard vanilla algorithm to calculate a comparator output for how "full" the inventory is. This method is an adaptation of Container#calcRedstoneFromInventory(IInventory).

Parameters:

inv - The inventory handler to test.

Returns:

A redstone value in the range [0,15] representing how "full" this inventory is.
