[1.6.4] [SOLVED] Making Mob Only Follow Tempt By Owner

saxon564 · November 10, 2013

so what i am trying to do now to finish off this mob so i can make the rest of them is make it so the mob will only be tempted by the owner and no one else if they are holding the tempt item, i have thought about it and looked at the code but am coming up blank. im not sure if overriding the method for that is a good idea or if i should remake the EntityAITempt class and modify it to what i need to do.

Here is my mobs entity code:

the line i know i need to focus on for this issue is

this.tasks.addTask(3, new EntityAITempt(this, 1.0D, Block.blockDiamond.blockID, false));

does anyone have any ideas as to what i could do to make the mob only follow the owner and no one else holding a diamond block?

TheGreyGhost · November 10, 2013

Hi

Perhaps you could create a new AI class from the existing one? eg if you want the pet to follow the closest person if it is the owner and is holding a diamond:

class MyEntityAITempt extends EntityAITempt {

@Override
   public boolean shouldExecute()
    {
        if (this.delayTemptCounter > 0)
        {
            --this.delayTemptCounter;
            return false;
        }
        else
        {
            this.temptingPlayer = this.temptedEntity.worldObj.getClosestPlayerToEntity(this.temptedEntity, 10.0D);

/* get owner of a pet
EntityTameable::
    public EntityLivingBase func_130012_q()
    {
        return this.worldObj.getPlayerEntityByName(this.getOwnerName());
    }
*/
            if (this.temptingPlayer != this.func_130012_q()) return false; 
            if (this.temptingPlayer == null)
            {
                return false;
            }
            else
            {
                ItemStack itemstack = this.temptingPlayer.getCurrentEquippedItem();
                return itemstack == null ? false : itemstack.itemID == this.breedingFood;
            }
        }
    }

I haven't tested this but I'm pretty sure it will work....

using what you said i now have this class:

package mods.mochickens.misc;

import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.ai.EntityAITempt;
import net.minecraft.item.ItemStack;

class ChickAITempt extends EntityAITempt {

@Override
public boolean shouldExecute() {
	if (this.getDelayTemptCounter() > 0) {
		this.setDelayTemptCounter(this.getDelayTemptCounter() - 1);
		return false;
	} else {
		this.setTemptingPlayer(this.getTemptedEntity().worldObj
				.getClosestPlayerToEntity(this.getTemptedEntity(), 10.0D));

		if (this.getTemptingPlayer() != this.func_130012_q())
			return false;
		if (this.getTemptingPlayer() == null) {
			return false;
		} else {
			ItemStack itemstack = this.getTemptingPlayer()
					.getCurrentEquippedItem();
			return itemstack == null ? false : itemstack.itemID == this
					.getBreedingFood();
		}
	}
}

public EntityLivingBase func_130012_q() {
	return this.worldObj.getPlayerEntityByName(this.getOwnerName());
}  
}

it is showing 2 errors.

here:

class [u]ChickAITempt[/u] extends EntityAITempt {

telling me i have to make a construtor

and here:

return this.[u]worldObj[/u].getPlayerEntityByName([u]this.getOwnerName()[/u]);

worldObj: says to create field or constant

this.getOwnerName(): says to create method

i imagine that the this.getOwnerName() will be solved when worldObj is solved, but idk how i need to go about fixing that. as for the constructor, should i make it then call the method?

TheGreyGhost · November 11, 2013

Hi

Try this constructor

    public ChickAITempt(EntityCreature temptedEntityInit, double movementSpeedInit, int temptingItemIDInit, boolean scaredByPlayerMovementInit)
    {
       super(temptedEntityInit, movementSpeedInit, temptingItemIDInit, scaredByPlayerMovementInit);
    }

The function func_130012_q is already defined for a tameable entity. It might be called EntityTameable.getOwnerEntity in your version of Forge. No need to add it to your ChickAITempt

saxon564 · November 13, 2013

so ive tried multiple ways to get the owner but none of them have worked, this is where i have stopped:

package mods.mochickens.misc;

import net.minecraft.entity.EntityCreature;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.ai.EntityAITempt;
import net.minecraft.entity.passive.EntityTameable;
import net.minecraft.item.ItemStack;

class ChickAITempt extends EntityAITempt {

public ChickAITempt(EntityCreature temptedEntityInit, double movementSpeedInit, int temptingItemIDInit, boolean scaredByPlayerMovementInit)
    {
       super(temptedEntityInit, movementSpeedInit, temptingItemIDInit, scaredByPlayerMovementInit);
    }

@Override
public boolean shouldExecute() {
	if (this.getDelayTemptCounter() > 0) {
		this.setDelayTemptCounter(this.getDelayTemptCounter() - 1);
		return false;
	} else {
		this.setTemptingPlayer(this.getTemptedEntity().worldObj
				.getClosestPlayerToEntity(this.getTemptedEntity(), 10.0D));

		if (this.getTemptingPlayer() != EntityTameable.getOwner())
			return false;
		if (this.getTemptingPlayer() == null) {
			return false;
		} else {
			ItemStack itemstack = this.getTemptingPlayer()
					.getCurrentEquippedItem();
			return itemstack == null ? false : itemstack.itemID == this
					.getBreedingFood();
		}
	}
}

//public EntityLivingBase func_130012_q() {
//	return this.worldObj.getPlayerEntityByName(this.getOwnerName());
//}  
}

im still having the problem on this line:

if (this.getTemptingPlayer() != EntityTameable.getOwner())

there error is saying to change the modifier of getOwner() to static in EntityTameable.

ive tried getting it the owner the same way as in other classes ive seen, such as using worldObj.

TheGreyGhost · November 13, 2013

Hi

Could you please show your chick entity class?

If it derives from EntityTameable (like wolf or ocelot), then it will be available from your EntityCreature

http://greyminecraftcoder.blogspot.com/2013/10/the-most-important-minecraft-classes_9.html

Otherwise, you will need to add your own field to your chick entity class to keep track of the owner. Or alternatively, add it to the constructor for ChickAITempt

public ChickAITempt(EntityCreature temptedEntityInit, EntityPlayer owner, double movementSpeedInit, int temptingItemIDInit, boolean scaredByPlayerMovementInit)
    {
       super(temptedEntityInit, movementSpeedInit, temptingItemIDInit, scaredByPlayerMovementInit);
       this.ownerName = .getCommandSenderName();
    }

private String ownerName = new String();

}

etc

Have a look at the code for EntityTameable - around setOwner, getOwner (etc). It uses a DataWatcher object to keep track of who the owning player is - otherwise it will "forget" every time you save the game. You will need to add these methods to your chick Class if you want the same "tame" functions.

I cannot call on a dataWatcher to get the owner, otherwise it tells me to set it to a static method which dataWatcher cannot run in. so im getting stuck in a loop of "set the method to a static method" "remove static modifier from this method" and the only way to get past that is to modify the entity class which i refuse to do. i tried adding my own dataWatcher but the game crashed when i tried spawning in the mob with the error: id already taken.

Why not have a look at what I did to add an owner to summoned creatures such as skeletons: https://github.com/coolAlias/ArcaneLegacy/blob/master/src/entity/summons/SummonSkeleton.java

There are also several AI examples that involve referencing the owner. The code is probably far from perfect, but it works.

i figured it out. i got around the static problem by setting a variable equal to the owner. then i did some logger data to fix issues with the tempting player and the owner not matching when i knew it should match. so now here is my updated shouldExicute() method.

public boolean shouldExecute() {

	String owner = this.getTemptedEntity().getDataWatcher()
			.getWatchableObjectString(17);

	if (this.getDelayTemptCounter() > 0) {
		this.setDelayTemptCounter(this.getDelayTemptCounter() - 1);
		return false;
	} else {
		this.setTemptingPlayer(this.getTemptedEntity().worldObj
				.getClosestPlayerToEntity(this.getTemptedEntity(), 10.0D));

		if (this.getTemptingPlayer() == null) {
			return false;
		} else if (this.getTemptingPlayer().getEntityName() != owner) {
			return false;
		} else {
			ItemStack itemstack = this.getTemptingPlayer()
					.getCurrentEquippedItem();
			return itemstack == null ? false : itemstack.itemID == this
					.getBreedingFood();
		}
	}
}

ive tested it and it works like it should, i can now finally get on and finish the mod! thank you for your help.
