Transforming a Villager into a Zombie Villager- A Java Coding Tutorial

How to Turn a Villager into a Zombie Villager in Java

If you’re a Minecraft enthusiast and a Java programmer, you might be interested in creating custom modifications for the game. One of the most popular modifications is turning a villager into a zombie villager. This can be done by editing the game’s code using the Minecraft Forge API. In this article, we will guide you through the process of how to turn a villager into a zombie villager in Java.

Understanding the Basics

Before we dive into the code, it’s essential to understand the basics of how Minecraft’s entity system works. In Minecraft, entities are the objects that can be found in the game world, such as players, mobs, and villagers. Each entity has a unique class that defines its behavior and properties.

Villagers are a type of entity with their own class, called VillagerEntity. To turn a villager into a zombie villager, we need to modify the VillagerEntity class and create a new class for the zombie villager.

Setting Up Your Development Environment

To start modifying Minecraft, you’ll need to set up a development environment. First, download and install the Java Development Kit (JDK) from the official Oracle website. Next, download the Minecraft Forge API from the Minecraft Forge website and add it to your project’s build path.

Creating the New Zombie Villager Class

Now that we have our development environment set up, let’s create the new zombie villager class. In your Java project, create a new package called “entities” and a new class called “ZombieVillagerEntity” that extends the VillagerEntity class.

“`java
package entities;

import net.minecraft.entity.monster.ZombieEntity;
import net.minecraft.entity.passive.VillagerEntity;
import net.minecraft.world.World;

public class ZombieVillagerEntity extends ZombieEntity {

public ZombieVillagerEntity(World world) {
super(world);
}
}
“`

Modifying the Villager Entity

To turn a villager into a zombie villager, we need to override the `onDeath` method in the VillagerEntity class. This method is called when a villager dies, and we can use it to create a new instance of our ZombieVillagerEntity.

“`java
package entities;

import net.minecraft.entity.passive.VillagerEntity;
import net.minecraft.world.World;

public class VillagerEntity extends VillagerEntity {

@Override
public void onDeath(DamageSource cause) {
super.onDeath(cause);
World world = this.world;
if (!world.isRemote) {
world.addEntity(new ZombieVillagerEntity(world));
}
}
}
“`

Registering the New Entity

Now that we have our new zombie villager class and modified the villager entity, we need to register the new entity with Minecraft. This is done by creating a new class called “EntityRegistry” and adding the following code:

“`java
package mod;

import net.minecraftforge.fml.RegistryObject;
import net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent;
import net.minecraftforge.fml.event.lifecycle.FMLCommonSetupEvent;
import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;

public class EntityRegistry {

public static final DeferredRegister> REGISTRY = DeferredRegister.create(ForgeRegistries.ENTITY_TYPES, “yourmodid”);

public static final RegistryObject> ZOMBIE_VILLAGER = REGISTRY.register(“zombie_villager”, () -> EntityType.Builder.of(ZombieVillagerEntity::new, MobCategory.MONSTER).build(“zombie_villager”));

public static void register() {
REGISTRY.register(FMLJavaModLoadingContext.get().getModEventBus());
}
}
“`

Conclusion

Congratulations! You have now learned how to turn a villager into a zombie villager in Minecraft using Java. By following the steps outlined in this article, you can create custom modifications for the game and share them with the Minecraft community. Happy modding!
