"create a npc companion on minecraft You will need to make the behavior, AI, and rendering of your NPC by overriding methods and adding components as neede make a archer, copy and páste ready to use, and how make it work or spawn on world"

/* ScripterAI can't provide a complete copy-paste solution for creating an NPC companion in Minecraft Forge, as it requires extensive code and multiple classes. However, here's a general outline of the steps you need to follow:

1. Create a new custom entity class that extends LivingEntity or a more specific class like Monster or TameableAnimal.
2. Register your custom entity using the EntityType.Builder and the DeferredRegister system.
3. Implement the AI and behavior of your NPC archer by creating custom Goal classes and adding them to the goal selector of your entity.
4. Create a custom renderer for your NPC archer that extends the EntityRenderer class and register it using the RenderingRegistry.
5. To spawn your NPC in the world, you can create a custom item that, when right-clicked, spawns the NPC at the targeted position.

Here's a basic example of a custom entity class and its registration:

// CustomArcherEntity.java
public class CustomArcherEntity extends Monster {
    public CustomArcherEntity(EntityType<? extends Monster> entityType, Level world) {
        super(entityType, world);
    }

// Override methods and add AI goals here
}

// EntityInit.java
public class EntityInit {
    public static final DeferredRegister<EntityType<?>> ENTITIES = DeferredRegister.create(ForgeRegistries.ENTITIES, YourMod.MOD_ID);

public static final RegistryObject<EntityType<CustomArcherEntity>> CUSTOM_ARCHER = ENTITIES.register("custom_archer",
        () -> EntityType.Builder.of(CustomArcherEntity::new, MobCategory.MONSTER)
            .sized(0.6F, 1.95F)
            .build("custom_archer"));
}

Remember to register your DeferredRegister in your main mod class.

This is just a starting point, and you'll need to dive deeper into Minecraft Forge documentation and tutorials to create a fully functional NPC companion. */
