[SOLVED][1.6.4] Mob Following Other Players

saxon564 · October 30, 2013

I'm having a problem with my mob where once its tamed it works fine, but when I shut down the game for a day then come back, it is no longer acting as if its tamed even though it doesn't deal damage. So by default its suppose to be hostile, but when you tame it, its no longer hostile and isn't suppose to attack anyone or anything, this works like it should, but the problem i stated above then come into play where after a day of not running the game, it will target you like its not tamed, but won't do damage as if it is. Also the other thing that goes hand in hand with this issue, is that since this is a chicken, i want it to lay something only when its tamed. But as with the targeting it will stop laying the item. Does anyone have any idea why this is?

Heres my code:

Everything ive tried to fix it before i made this post didnt work. Does anyone have any ideas?

saxon564 · November 1, 2013

anyone have any thoughts about this?

saxon564 · November 2, 2013

still hasn't been solved. if there is any information that you need that isn't on here, just let me know and i will add it.

coolAlias · November 2, 2013

Does this occur when you play your mod with the real Minecraft launcher, or only in Eclipse? If it's happening only when you run your mod from Eclipse, that would be because the username changes each time you restart the Eclipse client, so the chicken is 'tamed' but can't find its owner.

saxon564 · November 2, 2013

but even if the owner isnt anywhere i dont want it chasing any other players. thats where the problem is, i dont know what i need to change to stop it from chasing other players.

coolAlias · November 2, 2013

What debugging steps have you taken? Have you checked that you are really removing the AI for finding the nearest player? Are you sure that the chicken is still tamed when you restart the world? How about during the constructor stage, is the chicken 'tamed' while it is loading from the constructor, or does the tamed status only kick in after that stage?

That's my bet: the chicken's constructor is called first, at which point it hasn't loaded the value of 'isTamed' from NBT, so you add the AI for attacking the nearest player, then the NBT loads and it's set to tamed and loses the ability to do damage, but retains its AI.

What I'd do is override the setTamed method and put all the code changing the AI in there, then use that method when loading from NBT (which is done in the super, since you're not saving anything extra), so you'll have to override that method as well to call your setTamed if it's not already set up that way.

saxon564 · November 2, 2013

ok, well i looked through the readEntityNBT method and changed the check in the constructor from !isTamed() to if (this.getOwner() == null).

now the last thing id like to get working is that it will only be tempted by its owner. I've looked at everything about tempting that i could find and the only way i could figure out is to remake the EntityAITempt class and modify it, the problem is that I dont know where the ShouldExicute() method is called and used and I can't call on entity.getOwner() to check if the tempting player is its owner or not. are there any suggestions for what i should to to get around this? or where to look?

saxon564 · November 3, 2013

upon further testing, i found out that what i did actually didnt work, it stopped the mob from chasing players, but it set it to that with mobs that werent tamed. im just lost with this. could someone show me some sort of an example so i can see what it should look like?

coolAlias · November 3, 2013

You can't set this particular AI in the constructor and expect it to work - there is no owner at this point as the entity has not yet been read from NBT. Do you understand that? You can do it in the constructor when constructing a NEW entity after the world is loaded by passing in a valid EntityPlayer object, but otherwise you need to access the methods when reading from NBT.

Here's what I use for summoned creatures, but you have to understand what I wrote in my previous post about setting AI from within a method such as setOwner or setTamed for it to work:

@Override
public final void readEntityFromNBT(NBTTagCompound par1NBTTagCompound)
{
super.readEntityFromNBT(par1NBTTagCompound);
String s = par1NBTTagCompound.getString("Owner");

if (s.length() > 0)
{
	this.setOwner(s);
	this.setTamed(true);
}

this.aiSit.setSitting(par1NBTTagCompound.getBoolean("Sitting"));
this.setSitting(par1NBTTagCompound.getBoolean("Sitting"));
this.setLifespan(par1NBTTagCompound.getInteger("Lifespan"));
}
// Here's an example of how I set the AI whenever the owner changes - so this automatically updates the
// AI even for the constructor, as I call this method rather than setting things manually
/**
* Sets owner's name and adds AI to follow owner
*/
public final void setOwner(String par1Str)
{
this.dataWatcher.updateObject(17, par1Str);
if (par1Str.length() > 0)
	this.tasks.addTask(4, new EntityAIFollowSummoner(this, this.getOwner(), 1.0D, 10.0F, 2.0F));
}

saxon564 · November 6, 2013

lets see if im understand this right, if i am and i'm in fact doing it right, then its still not working, otherwise, a more in depth explanation might help?

so what your saying is, i need to override the readEntityFromNBT and call on another method if the section that sets the mob being tamed to set the tasks the way they need to be set?

eg.

public final void readEntityFromNBT(NBTTagCompound par1NBTTagCompound) {
	super.readEntityFromNBT(par1NBTTagCompound);
	String s = par1NBTTagCompound.getString("Owner");

	if (s.length() > 0) {
		this.setTamed(true);
		this.setOwner(s);
		this.setTasks();
	}
}


public void setTasks() {
	if (this.isTamed()) {
		this.worldObj.setEntityState(this, (byte) 7);
		this.tasks.removeTask(new EntityAIAttackOnCollide(this,
				EntityPlayer.class, 1.0D, false));
		this.targetTasks.removeTask(new EntityAINearestAttackableTarget(
				this, EntityPlayer.class, 0, true));
		this.tasks.addTask(3, new EntityAITempt(this, 1.0D,
				Block.blockDiamond.blockID, false));
		this.timeUntilNextEgg = this.rand.nextInt(6000) + 6000;
	}
}

coolAlias · November 6, 2013

Basically, yes, but it all depends on what else is going on in your Entity methods. Please post your entire Entity code, as well as explain what specifically isn't working. Is the Entity still attacking players? Still following random players? The more specific you are, the easier it is to pinpoint the problem.

I would recommend printing some information to the console when reading from NBT so you can see if there is an owner, what the owner's name is, and any other information you think might be relevant. This will help you troubleshoot.

ive tried putting the tasks in either part of the if in the setTamed and neither of the changes seemed to work, the chicken still chased other players without dealing damage after restarting the world.

Ok, so the EntityAIAttackOnCollide task is successfully removed, but the target task EntityAINearestAttackableTarget is not being removed even though it is in the same block of code. I don't know why that would be, but I can think of two options for you:

1. Look through the removeTask code and see if there is something that would prevent your target task from being removed successfully, then adjust your code to fix it.

2. Use 'this.targetTasks.clear()' instead, as I'm guessing you don't have any other target tasks anyway.

If none of that works, then I'd suggest figuring out what all of those field_7088x fields are for; perhaps the boolean type field is the same as isTamed and it's always set to false? Why on earth would you name fields like that in a class you built yourself anyway?

	}
}

the check on if the mob is tamed or not causes it not to do damage if its tamed.

targetTasks does not have a clear() method.

the field_7088x is not something i coded, i told the code from vanilla files that did essentially what i wanted, i just had to modify it to what i need it to do, which is whats causing the trouble.

the method removeTask() is shown as this:

public void removeTask(EntityAIBase par1EntityAIBase)
    {
        Iterator iterator = this.taskEntries.iterator();

        while (iterator.hasNext())
        {
            EntityAITaskEntry entityaitaskentry = (EntityAITaskEntry)iterator.next();
            EntityAIBase entityaibase1 = entityaitaskentry.action;

            if (entityaibase1 == par1EntityAIBase)
            {
                if (this.executingTaskEntries.contains(entityaitaskentry))
                {
                    entityaibase1.resetTask();
                    this.executingTaskEntries.remove(entityaitaskentry);
                }

                iterator.remove();
            }
        }
    }

this does not show much much in which i could change in my code.

I added a couple lines to the logging process to make it easier to see where it is coming from and here is what im getting.

from what i am seeing, it is setting up 3 more entities after the tamed one, i am wondering if there is a way to see if they are the same instance of the tamed one, or if they are different instances or it. if they are the same instance then that would explain why the targetTask doesnt seem to be getting removed.

targetTasks.taskEntries.clear() will clear all entries in targetTasks.

BUT, the removeTask method should work, so the problem is elsewhere. Try removing all of the oddly-named fields from your code. You really shouldn't need them for anything, since whatever they are for should be dealt with in the super class.

FINALLY!!!!

targetTasks.taskEntries.clear() was all i needed. i replaced

this.targetTasks.removeTask(newEntityAINearestAttackableTarget(this, EntityPlayer.class, 0, true));

with the clear() and now it works! thank you so much!
