Solved Angry chicken entities tickle players instead of attacking

I'm trying to create a hostile chicken, but for some reason the chickens will track and circle the player as if they were going to attack, but instead they don't attack and players laugh at the hyperactive flock of chickens encircling them.

Here's the class I created for testing:

Code:java

 
package com.ne0nx3r0.rih.entities;
 
import java.lang.reflect.Field;
import net.minecraft.server.v1_7_R3.EntityChicken;
import net.minecraft.server.v1_7_R3.EntityHuman;
import net.minecraft.server.v1_7_R3.GenericAttributes;
import net.minecraft.server.v1_7_R3.PathfinderGoalFloat;
import net.minecraft.server.v1_7_R3.PathfinderGoalHurtByTarget;
import net.minecraft.server.v1_7_R3.PathfinderGoalLookAtPlayer;
import net.minecraft.server.v1_7_R3.PathfinderGoalMeleeAttack;
import net.minecraft.server.v1_7_R3.PathfinderGoalMoveTowardsRestriction;
import net.minecraft.server.v1_7_R3.PathfinderGoalNearestAttackableTarget;
import net.minecraft.server.v1_7_R3.PathfinderGoalRandomLookaround;
import net.minecraft.server.v1_7_R3.PathfinderGoalRandomStroll;
import net.minecraft.server.v1_7_R3.PathfinderGoalSelector;
import net.minecraft.server.v1_7_R3.World;
import org.bukkit.craftbukkit.v1_7_R3.util.UnsafeList;
 
public class RIHEntityChicken extends EntityChicken{
 
    public RIHEntityChicken(World world) {
        super(world);
 
        try {
            Field bField = PathfinderGoalSelector.class.getDeclaredField("b");
            bField.setAccessible(true);
            Field cField = PathfinderGoalSelector.class.getDeclaredField("c");
            cField.setAccessible(true);
            bField.set(goalSelector, new UnsafeList<PathfinderGoalSelector>());
            bField.set(targetSelector, new UnsafeList<PathfinderGoalSelector>());
            cField.set(goalSelector, new UnsafeList<PathfinderGoalSelector>());
            cField.set(targetSelector, new UnsafeList<PathfinderGoalSelector>());
        }
        catch (Exception exc) {
            exc.printStackTrace();
        }
 
        this.goalSelector.a(0, new PathfinderGoalFloat(this));
        this.goalSelector.a(2, new PathfinderGoalMeleeAttack(this, EntityHuman.class, 1.0D, false));
        this.goalSelector.a(5, new PathfinderGoalMoveTowardsRestriction(this, 1.0D));
        this.goalSelector.a(7, new PathfinderGoalRandomStroll(this, 1.0D));
        this.goalSelector.a(8, new PathfinderGoalLookAtPlayer(this, EntityHuman.class, 8.0F));
        this.goalSelector.a(8, new PathfinderGoalRandomLookaround(this));
        this.targetSelector.a(1, new PathfinderGoalHurtByTarget(this, true));
        this.targetSelector.a(2, new PathfinderGoalNearestAttackableTarget(this, EntityHuman.class, 0, true));
    }
 
    @Override
    public String getName(){
        return "Cucco";
    }
 
    @Override
    protected void aC() {
        super.aC();
 
        // follow range
        this.getAttributeInstance(GenericAttributes.b).setValue(40.0D);
 
        // movement speed
        //this.getAttributeInstance(GenericAttributes.d).setValue(0.23000000417232513D);
        this.getAttributeInstance(GenericAttributes.d).setValue(0.53000000417232513D);
 
        // attack damage
        //this.getAttributeInstance(GenericAttributes.e).setValue(3.0D);
 
        //this.bb().b(bp).setValue(this.random.nextDouble() * 0.10000000149011612D);
    }
}
 

Curiously, if I use this same class without changing or uncommenting anything but extending from Ocelot instead of Chicken (to create an angry cat) that works as expected.

Is there something specific about chickens that prevents them from attacking?

 

Maybe a chicken can't attack?

 

I did a little digging and what didn't occur to me before was that Ocelots do attack, but somewhat ironically only go for chickens. I didn't know cats attacked anything which is why I choose them as a comparison test.

After some digging in these classes:
https://github.com/Bukkit/mc-dev/blob/master/net/minecraft/server/EntityChicken.java
https://github.com/Bukkit/mc-dev/blob/master/net/minecraft/server/EntityZombie.java
https://github.com/Bukkit/mc-dev/blob/master/net/minecraft/server/EntityOcelot.java

It seems overriding these two methods might do the trick:

Code:java

 @Override
public boolean n(Entity entity) {
return entity.damageEntity(DamageSource.mobAttack(this), 3.0F);
}
 
@Override
public boolean damageEntity(DamageSource damagesource, float f) {
if (this.isInvulnerable()) {
return false;
} else {
return super.damageEntity(damagesource, f);
}
}

I wont be able to test this until I get home, but I'll give it a shot.

*edit* It worked
