1.11 - Custom mob ignoring player

[Eria8]

My mob won't attack or even acknowledge the player.

It should have everything else it needs from extending EntityMob, and I don't see any classes like EntityZombie, etc, doing anything special...

Is setting its AI not enough?

public class Hunter extends EntityMob
{
	public Hunter(World world)
	{
		super(world);
		this.experienceValue = 30;
		this.setSize(0.5F, 1.8F);
	}

	@Override
	protected void applyEntityAttributes()
	{
		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.MAX_HEALTH).setBaseValue(50);
		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.KNOCKBACK_RESISTANCE).setBaseValue(0.01);
		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.ATTACK_DAMAGE).setBaseValue(4);
		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.ATTACK_SPEED);
		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.MOVEMENT_SPEED);
		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.FOLLOW_RANGE);
		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.LUCK);
		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.ARMOR);
		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.ARMOR_TOUGHNESS);
	}
 
	@Override
	protected void initEntityAI()
	{
		this.tasks.addTask(0, new EntityAISwimming(this));
		this.tasks.addTask(5, new EntityAIMoveTowardsRestriction(this, 1.0D));
		this.tasks.addTask(6, new EntityAIMoveThroughVillage(this, 1.0D, false));
		this.tasks.addTask(7, new EntityAIWanderAvoidWater(this, 1.0D));
		this.tasks.addTask(8, new EntityAIWatchClosest(this, EntityPlayer.class, 8.0F));
		this.tasks.addTask(8, new EntityAILookIdle(this));
		this.targetTasks.addTask(1, new EntityAINearestAttackableTarget(this, EntityPlayer.class, true));
	}
 
  	protected boolean canEquipItem(ItemStack stack)
	{
		return stack.getItem() instanceof ItemSword || stack.getItem() instanceof MeleeWeapon;
	}
 
	@Nullable
	public IEntityLivingData onInitialSpawn(DifficultyInstance difficulty, @Nullable IEntityLivingData livingdata)
	{
		this.setItemStackToSlot(EntityEquipmentSlot.MAINHAND, new ItemStack(Items.IRON_SWORD));
		return livingdata;
	}
 
	public float getEyeHeight()
	{
		return 1.75F;
	}
 
	protected boolean isValidLightLevel()
	{
		return true;
	}
}

Where did applyEntityAI() go? You probably need that.

You don't need the @Override in the applyEntityAttributes, and you need to call the super method on that. Look at the EntityZombie class.

 

EDIT: sorry, I was looking at 1.10 source, this may or may not work for you.

 

EDIT 2: Yes, my suggestion is still the same, look at the EntityZombie class.

I only see that in EntityZombie. It seems to be pretty useless and it's not in a super class, so why would I use it?

I'm doing everything in that method that's in all super methods, so that shouldn't matter...

		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.KNOCKBACK_RESISTANCE).setBaseValue(0.01);
		this.getAttributeMap().registerAttribute(SharedMonsterAttributes.ATTACK_DAMAGE).setBaseValue(4);
	}

If I do it that way, every time I try to spawn the mob it cancels the spawn and spams this error: "Caused by: java.lang.IllegalArgumentException: Attribute is already registered!".

 

So I completely removed the method, so that it should all be default attributes, and it still changed nothing. The mob still doesn't target the player. Attributes are not the problem.

Okay that helped fix what I was doing wrong with attributes, but it still does not fix the problem. It's even more evidence that the problem has nothing to do with attributes...

[Eria8]

Anyone?

I think you need to add something like this: this.tasks.addTask(2, new EntityAIZombieAttack(this, 1.0D, false));

This is what I was looking for. I thought that was something else, didn't see that it extended the EntityAIMeleeAttack which apparently now gives mobs the AI to actually attack. Now just have to fix its glitchy movement... Thanks!

[Leomelonseeds]

No problem.
