Preparing Your Development Environment

Before embarking on the journey of creating a Minecraft mod, you need to establish a solid development environment. This section will guide you through the necessary steps to prepare your workstation for the task at hand.

1. Installing Java

Minecraft mods are written in the Java programming language. Therefore, you must install Java on your system. Visit the official Java website and download the latest version compatible with your operating system. Once downloaded, follow the installation wizard’s instructions to complete the installation process.

Operating System Download Link
Windows https://www.java.com/en/download/
macOS https://www.java.com/en/download/mac_download.jsp
Linux https://www.java.com/en/download/linux_download.jsp

After installation, verify the success by opening a terminal or command prompt and typing the following command:

java -version

You should see output similar to the following:

java version "18.0.2.1" 2023-02-14 LTS

This confirms that Java is correctly installed and ready for use.

Installing Neoforge and Its Dependencies

Installing Neoforge is straightforward and requires minimal software prerequisites. Before proceeding, ensure you have the following dependencies installed:

JDK 17

Neoforge requires Java Development Kit (JDK) 17 to function properly. You can download it from the official Oracle website.

Maven

Maven is a build automation tool used by Neoforge. You can install it using a package manager like Homebrew for macOS or apt-get for Linux.

Operating System Installation Command
macOS brew install maven
Linux (Debian/Ubuntu) sudo apt-get install maven

Node.js (Optional)

Node.js is only necessary if you intend to use the Neoforge web interface. You can install it from the official Node.js website.

Creating a New Minecraft Mod Project

To begin creating a new Minecraft mod using Neoforge, follow these steps:

  1. Install the Neoforge mod loader.
  2. Create a new directory for your mod.
  3. Inside the directory, create a file named build.gradle with the following contents:
    4. plugins { id 'fabric-loom' version '0.12-SNAPSHOT'
    }
    dependencies {
    minecraft "net.minecraftforge:forge:1.19.2-43.1.65"
    mappings "net.minecraftforge:forge:1.19.2-43.1.65"
    }
  4. Create a new file named src/main/java/YOUR_MOD_ID/ExampleMod.java with the following contents:
    5. package YOUR_MOD_ID;
    import net.minecraft.item.Item;
    import net.minecraft.item.ItemStack;
    import net. minecraft.util.Identifier;
    import net.minecraft.util.registry.Registry;
    public class ExampleMod {
    public static final Item STONE = new Item(new Item.Settings());
    public static void register() {
    Registry.register(Registry, new Identifier("YOUR_MOD_ID", "stone"), STONE);
    }
    }
  5. Run the following command to build the mod:

    6. ./gradlew build

  6. Copy the .jar file from the build/libs directory to the mods directory in your Minecraft installation.
  7. Run Minecraft and enjoy your new mod!

Writing Your Mod’s Code

Now that you have a basic understanding of the Minecraft modding API, it’s time to start writing your own code. The first step is to create a new Java class for your mod. You can do this by right-clicking on the “src” folder in your Eclipse project and selecting “New” -> “Class”.

In the “Name” field, enter the name of your mod class. For example, if you’re creating a mod that adds a new item to the game, you could name your class “MyNewItemMod”.

Once you’ve created your mod class, you can start adding code to it. The following code shows you how to register a new item with the Minecraft API:

Java

public class MyNewItemMod extends Mod {

public static Item myNewItem;

@Override
public void init() {
myNewItem = new Item()
.setRegistryName(“my_new_item”)
.setUnlocalizedName(“My New Item”);

GameRegistry.register(myNewItem);
}
}

This code creates a new item called “My New Item”. The item is registered with the Minecraft API using the GameRegistry.register() method.

You can also add your own event handlers to your mod class. Event handlers are methods that are called when certain events occur in the game. For example, you could create an event handler that is called when a player places a block. The following code shows you how to create an event handler:

Java
public class MyNewItemMod extends Mod {

public static Item myNewItem;

@Override
public void init() {
myNewItem = new Item()
.setRegistryName(“my_new_item”)
.setUnlocalizedName(“My New Item”);

GameRegistry.register(myNewItem);
}

@EventHandler
public void onBlockPlace(BlockPlaceEvent event) {
if (event.getPlacedBlock() == myNewItem) {
// Do something when the player places a block of My New Item
}
}
}

This code creates an event handler that is called when a player places a block. The event handler checks if the placed block is an instance of the myNewItem item. If it is, the event handler does something. In this case, the event handler prints a message to the console.

Compiling and Jarring Your Mod

Once your source code is complete, you’ll need to compile it to turn it into a jar file that can be loaded into Minecraft. Here’s how to do it:

Using a Build Tool

The recommended way to compile your mod is to use a build tool like Maven or Gradle. These tools automate the compilation process and can handle dependencies.

To use a build tool, you’ll need to set up a build file that defines the dependencies and build instructions. Once you have a build file, you can simply run the build command to compile your mod.

Using a Java Compiler

If you don’t want to use a build tool, you can compile your mod manually using the Java compiler. To do this, open a terminal window and navigate to the directory where your source code is located.

Then, run the following command:

javac -d output_dir -cp minecraft.jar:libraries/* src/*.java

This command will compile your source code and place the resulting class files in the output_dir directory.

Creating a Jar File

Once your mod is compiled, you’ll need to create a jar file to distribute it.

To create a jar file, open a terminal window and navigate to the directory where your class files are located. Then, run the following command:

jar -cvf mod.jar *.class

This command will create a jar file named mod.jar that contains your class files.

Including Dependencies

If your mod depends on other libraries or mods, you’ll need to include them in your jar file. To do this, use the -cp option when creating the jar file:

jar -cvf mod.jar *.class -cp library1.jar:library2.jar

This command will create a jar file that includes your class files as well as the dependencies from library1.jar and library2.jar.

Additional Tips

Here are some additional tips for compiling and jarring your mod:

    Tip Details Use a version control system This will help you keep track of changes to your mod and revert to previous versions if necessary. Test your mod thoroughly Make sure your mod works as expected before distributing it to others. Document your mod Provide clear instructions on how to install and use your mod.

Registering Your Mod in the Game

Once you’ve created your mod’s main class and defined its core functionality, you need to register it with the Forge mod loading system. This process involves creating a mod descriptor file (mod.json) and registering your mod class with Forge.

Creating the mod.json File

The mod.json file is a JSON-formatted file that contains metadata about your mod, such as its name, version, and dependencies. The following is an example of a basic mod.json file:

{
  "modid": "mymod",
  "name": "My First Mod",
  "version": "1.0.0",
  "description": "This is my first Minecraft mod.",
  "dependencies": []
}

Registering Your Mod Class

Once you’ve created the mod.json file, you need to register your mod class with Forge. This can be done using the @Mod annotation, which takes the modid as an argument. For example:

@Mod("mymod")
public class MyMod {
  // Mod initialization code goes here
}

Mod Loading Process

When Minecraft loads, it scans the mods directory for mod.json files. For each valid mod.json file, it attempts to load the corresponding mod class. When your mod class is loaded, Forge will invoke its preInit, init, and postInit methods in that order.

Initialization Methods

Forge provides several initialization methods that you can use to initialize your mod and register its content. These methods are:

  • preInit: This method is called before any other mod initialization methods. It is typically used to register event listeners and perform other early setup tasks.
  • init: This method is called after all other mod initialization methods. It is typically used to register blocks, items, and other game content.
  • postInit: This method is called after all other mod initialization methods. It is typically used to perform any final setup tasks, such as connecting to external APIs.

Customizing Your Mod’s Settings

Neoforge provides a powerful Settings class that allows you to easily customize your mod’s settings from within the game. To use the Settings class, you’ll need to create a new instance of it in your mod’s constructor:

Creating a Settings class:


@Mod.EventBusSubscriber(modid = [modID])
private static class Settings {

@SubscribeEvent
public static void register(RegisterConfigEvent event) {
event.register(Config.Type.INSTANCE);
}

@Config(modid = [modID])
public static final Config INSTANCE = new Config();

public static void save() {
if (INSTANCE.save) ConfigManager.sync(Config.INSTANCE);
}
}

The ConfigManager class provides methods for saving and loading your settings from disk. To save your settings, simply call the save() method on your Settings class. To load your settings, call the sync() method on the ConfigManager class, passing in your Settings class as an argument:

Method Description
ConfigManager.sync(Config config) Loads or saves the specified config

The Settings class also provides methods for getting and setting your settings values. To get a setting value, use the get() method on your Settings class:

Getting a setting value:


INSTANCE.someSetting.get()

To set a setting value, use the set() method on your Settings class:

Setting a setting value:


INSTANCE.someSetting.set(newValue)

Packaging and Distributing Your Mod

Once your mod is complete, it’s time to package and distribute it. This process involves creating a mod file and uploading it to a mod repository.

Create a Mod File

To create a mod file, you need to use a mod packaging tool like Forge Modpackager or MCPatcher. These tools will package your mod into a .jar file that can be installed in Minecraft.

Upload Your Mod to a Mod Repository

Once you have a mod file, you can upload it to a mod repository like CurseForge or ModDB. These repositories allow modders to share and download mods with the Minecraft community.

Create a Mod Page

When you upload your mod to a repository, you’ll need to create a mod page. This page will contain information about your mod, such as its name, description, and version number.

Add Screenshots and Videos

Screenshots and videos can help potential users visualize your mod and understand its features. Add as many screenshots and videos as possible to your mod page.

Set Release and Download Links

Finally, you’ll need to set the release and download links for your mod. The release link will point to the latest version of your mod, while the download link will point to the mod file itself.

Share Your Mod

Once your mod page is complete, share it with the Minecraft community. You can post about your mod on forums, social media, or your own website.

Continue to Update Your Mod

Once your mod is released, it’s important to continue to update it. This will ensure that your mod remains compatible with the latest version of Minecraft and that it continues to meet the needs of your users.

Respond to Feedback

It’s important to respond to feedback from your users. This feedback can help you identify bugs in your mod or areas that can be improved. By responding to feedback, you can ensure that your mod continues to meet the needs of the Minecraft community.
