FastRecipeCrafting

A lightweight client-side mod for Minecraft that speeds up crafting through the recipe book.

What it does

Normally, the recipe book can only place a recipe's ingredients into the crafting grid — you still have to grab the finished item yourself. This mod removes that extra step:

• First click on an item in the recipe book — places the recipe into the crafting grid, as usual.
• Second click on the same item — instantly crafts it (equivalent to shift-clicking the result slot), then automatically re-places the same recipe so you can keep crafting without extra clicks in between.
• Holding left click for more than ~0.5 seconds — starts auto-repeating the craft at the maximum speed the client tick allows, until you release the button or run out of ingredients.
• Holding Shift while placing a recipe — places the maximum available amount of ingredients into the grid at once, instead of a single set at a time.

How it works

The mod uses a Mixin into RecipeBookComponent (the client-side recipe book class):

• It intercepts tryPlaceRecipe — if the clicked recipe is already placed in the grid (lastPlacedRecipe) and craftable, instead of placing it again the mod calls MultiPlayerGameMode#handleContainerInput with ContainerInput.QUICK_MOVE on the result slot (index 0), which is equivalent to the player shift-clicking the finished item.
• tick() polls the physical state of the left mouse button and Shift key via GLFW (through Window and an accessor mixin on its private handle field) to implement button-holding and the "place all" modifier.

The mod is client-side only and requires nothing on the server — every action goes through the game's normal packets (handleContainerInput, handlePlaceRecipe), so from the server's/anti-cheat's perspective it's indistinguishable from a player clicking normally.

Known limitations

• Auto-craft speed while holding is capped by the client tick rate (20 tps) and how fast the server processes packets.
• The mod only works with standard crafting menus (crafting table). Other mods' custom RecipeBookMenu implementations with a different slot layout may need extra handling.
