Modding Minecraft can be a fun and exciting way to enhance your gameplay experience. Crafttweaker, a powerful modding tool, allows you to customize various aspects of the game to your liking. Whether you want to add new items, change recipes, or tweak game mechanics, Crafttweaker offers endless possibilities. In this beginner’s guide, we will walk you through the basics of using Crafttweaker to create your own custom Minecraft experience.

What is Crafttweaker?

Crafttweaker is a modding tool developed specifically for Minecraft. It allows you to make changes to the game’s crafting recipes, item properties, villager trades, and much more. With Crafttweaker, you can customize almost every aspect of Minecraft to suit your preferences. Whether you are a seasoned modder or just starting out, Crafttweaker provides a user-friendly interface to make the process easier.

Installing Crafttweaker

Before you can start using Crafttweaker, you need to install it properly. Here’s a step-by-step guide to help you:

  1. Download and install Minecraft Forge, a modding platform that Crafttweaker requires to run.
  2. Download the latest version of Crafttweaker from their official website.
  3. Locate your Minecraft installation folder and open the “mods” directory.
  4. Copy the Crafttweaker mod file that you downloaded into the “mods” directory.
  5. Launch Minecraft using the Forge profile. Crafttweaker should now be installed and ready to use.

Getting Started with Crafttweaker

Once you have successfully installed Crafttweaker, you can start creating your own customizations. Crafttweaker uses a scripting language called ZenScript, which may seem intimidating at first, but it’s relatively easy to learn. Here are a few key concepts to get you started:

1. Creating Custom Crafting Recipes

To create a custom crafting recipe, you need to define the input items and their arrangement. Here’s an example:

 recipes.addShaped("diamond_sword", , [ " D ", " D ", " S " ], { D: , S:  }); 

In the above example, we are using the recipes.addShaped function to define a new crafting recipe for a diamond sword. The arrangement of the items is specified using a 3×3 grid, where “D” represents a diamond and “S” represents a stick. The resulting item is a diamond sword. You can create your own custom recipes by modifying the input items and arrangement.

2. Modifying Existing Recipes

If you want to modify an existing recipe, you can use the recipes.remove and recipes.addShaped functions in combination. Here’s an example:

 recipes.remove(); recipes.addShaped("golden_apple", , [ " G ", "GGG", " G " ], { G:  }); 

In the above example, we first remove the existing crafting recipe for a golden apple using recipes.remove. Then, we add a new recipe using recipes.addShaped with the modified arrangement and input items.

3. Customizing Villager Trades

Crafttweaker also allows you to customize villager trades. Here’s an example:

 val librarian = utils.getVillagerProfession("minecraft:librarian"); val trade = librarian.addTrade(1, 1, [  * 10,  * 1 ]); trade.setMaxUses(10); trade.setExperienceReward(20); 

In the above example, we first retrieve the librarian villager profession using utils.getVillagerProfession. Then, we add a new trade to the librarian using the addTrade function, specifying the input and output items. Additional settings like maximum uses and experience rewards can also be customized.


Crafttweaker is a fantastic tool for Minecraft modding enthusiasts, offering a wide range of customization options. Whether you want to create custom crafting recipes, modify existing ones, or customize villager trades, Crafttweaker provides a user-friendly interface to make your vision a reality. By exploring the possibilities of Crafttweaker, you can unleash your creativity and take your Minecraft gameplay to new heights.

Remember, modding Minecraft can be a complex process, so it’s always a good idea to refer to Crafttweaker’s official documentation and community forums for additional guidance. Happy modding!
