Item & Tool Hooks

ItemStackHooks

dev.architectury.hooks.item.ItemStackHooks

Method	Description
copyWithCount(ItemStack, int)	A copy of the stack with a different count.
giveItem(ServerPlayer, ItemStack)	Add the stack to the player's inventory, dropping the remainder if it's full.
hasCraftingRemainingItem(ItemStack)	Whether the stack leaves a remainder after crafting (stack-aware only on NeoForge).
getCraftingRemainingItem(ItemStack)	The remainder stack left after crafting.

ItemStack three = ItemStackHooks.copyWithCount(stack, 3);
ItemStackHooks.giveItem(serverPlayer, new ItemStack(Items.DIAMOND, 5));

Tool interactions

These add the vanilla right-click tool behaviors to your own blocks, in one cross-platform call. Register them from your common initializer.

AxeItemHooks

dev.architectury.hooks.item.tool.AxeItemHooks

AxeItemHooks.addStrippable(MyBlocks.WAXED_LOG.get(), MyBlocks.STRIPPED_LOG.get());

Adds an axe stripping interaction. Both blocks must have the AXIS property (the axis is copied from input to result); otherwise this throws.

ShovelItemHooks

dev.architectury.hooks.item.tool.ShovelItemHooks

ShovelItemHooks.addFlattenable(MyBlocks.ASH_BLOCK.get(), MyBlocks.ASH_PATH.get().defaultBlockState());

Adds a shovel flattening (path) interaction. A block can only be flattened if there's no block directly above it.

HoeItemHooks

dev.architectury.hooks.item.tool.HoeItemHooks

HoeItemHooks.addTillable(
    MyBlocks.ROUGH_DIRT.get(),
    context -> true,                                  // Predicate<UseOnContext>
    context -> { /* extra side effects */ },          // Consumer<UseOnContext>
    context -> MyBlocks.TILLED_DIRT.get().defaultBlockState() // Function<UseOnContext, BlockState>
);

Adds a hoe tilling interaction: a predicate deciding when it applies, an action to run, and the resulting block state.
