You’ll learn how to define custom recipes using JSON, integrate them into your world, and troubleshoot common issues. Get ready to revolutionize your smelting experience!
Necessary Preparations and Tools
This guide is tailored for the most recent versions of Minecraft, so ensuring your game is up-to-date is the first step. Custom smelting recipes are typically defined using JSON (JavaScript Object Notation). Don’t be intimidated; JSON is a human-readable data format that’s easy to learn. Think of it as a structured way of describing your recipe to the game. Essentially, it’s a collection of key-value pairs.
You’ll need a suitable text editor for creating and editing these JSON files. A text editor with JSON syntax highlighting is highly recommended. Popular choices include VS Code, Notepad++, or Sublime Text. Syntax highlighting will visually distinguish different elements of your code, making it easier to spot errors.
While not strictly required, a basic understanding of Minecraft modding concepts, particularly datapacks, is helpful. Datapacks are the primary method for adding custom content to Minecraft without requiring modifications to the core game files. They provide a safe and flexible way to introduce new recipes, functions, structures, and more.
Enabling datapacks in your game is quite simple. Start by saving your world. Next you are going to go back to the Minecraft main menu. From here, you will go to the saves section, choose your world and click ‘edit’. Then you will want to select ‘Open World Folder’. In here you will be able to add your datapack folder inside another folder called datapacks.
Creating a New Smelting Recipe Using Datapacks
The key to adding your custom smelting recipe is the datapack structure. The correct folder structure is essential for Minecraft to recognize and load your custom recipes. Locate your Minecraft world folder. This is typically found in your Minecraft installation directory under saves/<your_world_name>.
Within your world folder, create a new folder named datapacks. Inside the datapacks folder, create another folder for your specific datapack. Name it something descriptive, like my_custom_recipes. This is where all your custom content will reside.
Now, navigate inside your datapack folder (datapacks/my_custom_recipes). You’ll need to create a series of subfolders to specify that you’re adding recipes. Create the following folder structure: data/<your_namespace>/recipes/. Replace <your_namespace> with a unique identifier for your mod or customization. This helps prevent conflicts with other datapacks. A good namespace might be your username or a shortened version of your mod’s name.
Finally, inside the recipes folder, you’ll create your JSON recipe file. The file name should be descriptive and follow a convention. For example, my_new_ore.json would be a suitable name for a recipe that smelts a custom ore.
Understanding Recipe Structure and Properties: The JSON Deep Dive
Open your chosen text editor and create a new file. This is where you’ll define your smelting recipe using JSON. The basic structure of a smelting recipe JSON file looks like this:
{
"type": "minecraft:smelting",
"ingredient": {
"item": "minecraft:example_item"
},
"result": "minecraft:example_result",
"experience": 0.7,
"cookingtime": 200
}
Let’s break down each of these properties:
Recipe Type
type: This specifies the type of recipe. For smelting recipes, it should always be "minecraft:smelting". This tells Minecraft that this is a smelting recipe and should be handled accordingly.
Ingredient Specification
ingredient: This defines the item that will be smelted. You can specify the ingredient using either the item property or the tag property.
Specific Item Ingredient
item: This specifies a single, specific item. For example, "item": "minecraft:iron_ore" would indicate that this recipe is for smelting iron ore.
Item Tag Ingredient
tag: This allows you to use item tags. Tags are groups of items that can be used interchangeably in recipes. This is particularly useful for mod compatibility, as it allows your recipe to work with different variations of the same item (e.g., different modded copper ores). The syntax for using a tag is "tag": "minecraft:coppers". You will need to create a custom tag if you have a new ore that doesn’t have an existing tag.
Result Specification
result: This defines the item that will be produced by smelting. You can specify the output item and its quantity using the item and count properties.
Resulting Item
item: Specifies the item to be created. For example, "item": "minecraft:iron_ingot" would create an iron ingot.
Result Count
count (Optional): Specifies the number of items to be created. If omitted, the default value is one. For example, "item": "minecraft:gold_nugget", "count": 3 would create three gold nuggets.
Experience Reward
experience: This determines the amount of experience points the player will receive when the smelting process is complete. The value should be a decimal number. A value of 0.7 is a reasonable amount for smelting iron ore.
Cooking Time
cookingtime: This determines how long the smelting process takes, measured in game ticks. One second in Minecraft is equal to twenty ticks. Therefore, a cookingtime of two hundred ticks would result in a smelting time of ten seconds.
Example Recipe: Smelting a New Ore Called Galactium
Let’s create a practical example: a recipe for smelting a fictional ore called “Galactium Ore” into “Galactium Ingot.” Assume we have a mod that adds “galactium_ore” and “galactium_ingot” to the game.
Here’s the complete JSON code for the recipe:
{
"type": "minecraft:smelting",
"ingredient": {
"item": "minecraft:galactium_mod:galactium_ore"
},
"result": "minecraft:galactium_mod:galactium_ingot",
"experience": 1.2,
"cookingtime": 250
}
In this recipe:
"type": "minecraft:smelting": Specifies that this is a smelting recipe."ingredient": { "item": "minecraft:galactium_mod:galactium_ore" }: Defines “galactium_ore” (from thegalactium_modnamespace) as the input item."result": "minecraft:galactium_mod:galactium_ingot": Defines “galactium_ingot” (also from thegalactium_modnamespace) as the output item."experience": 1.2: Sets the experience reward to one point two when the player smelts this ore."cookingtime": 250: Sets the smelting time to twelve and a half seconds.
Save this file as galactium_ore.json in the data/galactium_mod/recipes/ folder of your datapack.
Loading and Testing Your Recipe
Now that you’ve created your custom smelting recipe, it’s time to load it into your Minecraft world and test it out. Place your entire datapack folder (e.g., my_custom_recipes) into the datapacks folder of your world.
In-game, use the command /reload to reload all datapacks. This will apply your changes without requiring you to restart the game. If the command is unkown you will need to allow cheats in your world.
To test your recipe, you’ll need to obtain the input item (in our example, galactium_ore). If you’re in creative mode, you can use the /give command. For example: /give @s galactium_mod:galactium_ore.
Place the galactium_ore into a furnace, and you should see it start smelting into galactium_ingot. Verify that the output item, quantity, and experience reward are all correct.
Troubleshooting Common Issues
Even with careful planning, issues can arise. Here are some common problems and how to solve them:
JSON Syntax Errors
JSON syntax errors are the most frequent cause of recipe loading failures. Ensure that your JSON code is valid. Use a JSON validator website or your text editor’s built-in validation tools to check for errors. Common syntax errors include missing commas, mismatched brackets, and incorrect data types.
Recipe Loading Problems
If your recipe doesn’t appear in the game, double-check the datapack folder structure, file name, and recipe type. Make sure the datapack is correctly placed in the datapacks folder and that the /reload command was successful.
Unexpected Recipe Behavior
If the recipe loads but produces unexpected results (e.g., wrong output, incorrect experience), carefully review the JSON code for errors. Double-check the item IDs and quantities.
Console Errors
Pay attention to any errors that appear in the Minecraft console. These errors can often provide clues about what’s going wrong.
Advanced Techniques and Customization
Once you’ve mastered the basics, you can explore more advanced techniques:
Leveraging Item Tags
Utilize tags to create more flexible recipes that work with multiple items. This is especially useful when working with mods that add similar items (e.g., different types of copper ore).
Smelting Multiple Items Concurrently
While a single recipe file typically handles one smelting process, you can combine multiple recipes within a single datapack. Experiment with using functions to execute multiple recipes in specific scenarios.
Creating Custom Furnaces
For advanced modders, consider creating custom furnace blocks that have unique smelting properties or requirements. This requires more in-depth knowledge of Minecraft modding.
Conclusion
Creating custom smelting recipes in Minecraft is a powerful way to customize your gameplay, introduce new resources, and balance your world. By understanding the fundamentals of JSON, datapacks, and recipe properties, you can unlock a world of creative possibilities.
Don’t be afraid to experiment, try new things, and push the boundaries of what’s possible. Creating your own custom smelting recipes is a rewarding experience that can add a whole new dimension to your Minecraft world.
