Я без понятия актуально или нет но попробуй сменить класс [public class HumanEntity] на любой другой и попробуй запустить

dxAugust · 30 Июн 2022

Привет,

Возможно ты не совсем правильно задал атрибуты мобу.

Mr.Toad · 30 Июл 2022

попробуй так

Java:

public static AttributeModifierMap.MutableAttribute setCustomAttributes(){
        return MobEntity.func_233666_p_()
             //   Жизьки
        .createMutableAttribute(Attributes.MAX_HEALTH, 10.00)
               //Скорость Движения
        .createMutableAttribute(Attributes.MOVEMENT_SPEED, 0.7D)
              //Урон
        .createMutableAttribute(Attributes.ATTACK_DAMAGE, 0.00)
            //и тд.....
        


}

Mr.Toad · 30 Июл 2022

Атрибуты не применяются
создай вот такой класс

Java:

@Mod.EventBusSubscriber(modid = ue.MODID, bus = Mod.EventBusSubscriber.Bus.MOD)

public class Events {





//Здесь если надо можно записать это:

 @SubscribeEvent
  public static void onRegisterEntities(RegistryEvent.Register<EntityType<?>> event) {
  ModSpawnEggItem.initSpawnEggs();
    }
//Мобы Будут Спавнится Из ЯИЧЕК призыва если конечно ты их(ЯИЧКИ) создал
//ModSpawmEggItem класс ЯИЧЕК
}







    @SubscribeEvent

    public static void addEntityAttributes(EntityAttributeCreationEvent event) {

        event.put(EntityType./*здесь твой моб*/.get(), /*здесь твой класс HumanEntity*/.setCustomAttributes().create());

        
        //EntityType Класс с Регистрацией мобов
    }

Мне Помогло
