I am using forge version 1.16.1-32.0.63 and I wanted to create my own custom entity. I did not know how to set the mutable attributes, so I looked it up, but every search directed me to roughly the same code:

 

package com.gamingtiger.gttaa.entities;

import com.sun.org.apache.xml.internal.utils.MutableAttrListImpl;
import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityType;
import net.minecraft.entity.MobEntity;
import net.minecraft.entity.ai.attributes.Attribute;
import net.minecraft.entity.ai.attributes.AttributeModifierMap;
import net.minecraft.nbt.CompoundNBT;
import net.minecraft.network.IPacket;
import net.minecraft.world.World;

public class SuperZombieEntity extends Entity {
    public SuperZombieEntity(EntityType<?> entityTypeIn, World worldIn) {
        super(entityTypeIn, worldIn);
    }

    public static AttributeModifierMap.MutableAttribute setCustomAttribute() {
        return MobEntity.func_233666_p_().createMutableAttribute(Attribute.MAX_HEALTH, 100.0D);
    }

    @Override
    protected void registerData() {

    }

    @Override
    protected void readAdditional(CompoundNBT compound) {

    }

    @Override
    protected void writeAdditional(CompoundNBT compound) {

    }

    @Override
    public IPacket<?> createSpawnPacket() {
        return null;
    }
}

 

The problem is that the ".createMutableAttribute" does not exist and I don't know how to solve this.

 

I tested this with a passive mob and a mobentity.

Maybe it hasn't been mapped?

How do I map it?

You have to put it inside the GlobalEntityTypeAttributes

Where can I find those attributes, I looked but don't know where to find it

GlobalEntityTypeAttributes is a class, take a look inside it. Also:

    @Override
    public IPacket<?> createSpawnPacket() {
        return null;
    }

This should not return null

It says that the file is read only, so I can't edit the mappings
