[1.12.2] crash while ticking entity/updating task

[DeBugger]

Hey guys,

I added to my mob the tasks you can see here:

Spoiler

package com.cb.cyborg.entity;

import net.minecraft.entity.SharedMonsterAttributes;
import net.minecraft.entity.ai.EntityAIAttackMelee;
import net.minecraft.entity.ai.EntityAIHurtByTarget;
import net.minecraft.entity.ai.EntityAILookIdle;
import net.minecraft.entity.ai.EntityAINearestAttackableTarget;
import net.minecraft.entity.ai.EntityAISwimming;
import net.minecraft.entity.ai.EntityAIWatchClosest;
import net.minecraft.entity.monster.EntityZombie;
import net.minecraft.entity.passive.EntityVillager;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.world.World;

public class EntityCyborg1 extends EntityZombie
{
    public static String NAME = "cyborg1";
    
    public EntityCyborg1(World worldIn)
    {
        super(worldIn);    
    }
    
    @Override
    protected void initEntityAI()
    {
        this.tasks.addTask(0, new EntityAISwimming(this));
            this.tasks.addTask(1, new EntityAIAttackMelee(this, 1, false));
            this.tasks.addTask(2, new EntityAIHurtByTarget(this, false, new Class[0]));
            this.tasks.addTask(3, new EntityAINearestAttackableTarget(this, EntityVillager.class, true));
        this.tasks.addTask(4, new EntityAIWatchClosest(this, EntityPlayer.class, 6.0F));
        this.tasks.addTask(5, new EntityAILookIdle(this));
    }
    
    @Override
    protected void applyEntityAttributes()
    {
        super.applyEntityAttributes();
        this.getEntityAttribute(SharedMonsterAttributes.MAX_HEALTH).setBaseValue(40.0D);
        this.getEntityAttribute(SharedMonsterAttributes.MOVEMENT_SPEED).setBaseValue(0.25D);
        this.getEntityAttribute(SharedMonsterAttributes.ATTACK_DAMAGE).setBaseValue(5.0D);
        this.isImmuneToFire = true;
    }
    
    @Override
    protected boolean shouldBurnInDay()
    {
        return false;
    }
    
}

I cant figure out how to fix it. I only changed from gm 1 to gm 0, and then forge crashed. Here is the report:

NullPointerException

Something is null.

[DeBugger]

Thank you. I think I know what the failure was. I used an integer for an float variable. Dont no why, but the NullPointerException is no longer appearing.

Sorry I know that the following isnt that what the topic is called but I dont want to spam topics. How can I let my mob turning villagers on death to my mob? I think I have to override the default vanilla method, but I dont know how it is called. I couldnt find a method or attribute named like "TurnOnDeath" or something like that (I know it would be to easy). Does you or anybody else have an idea or advice?

[V0idWa1k3r]

See EntityZombie#onKillEntity

[DeBugger]

Thank you very much?

[DeBugger]

Sorry, where do I have to see "onKillEntity"? I dont have decompiled the sourcecode. Could you give me an advice where I can see the code or give me an example? Sorry.

Why? You should have the decompiled source code. It is pretty much necessary for learning modding. How did you setup your workspace?

[DeBugger]

I did it with setupDevWorkspace. The reason is that it seems like my computer on which I have my workspace doesnt have enough RAM to decompile. This problem should be fixed in a few days (hopely). Sorry for that.

[DaemonUmbra]

How much RAM is in your machine?

[DeBugger]

4 GB. Its a bit old machine (2-3 years old).

[V0idWa1k3r]

You only need 3 gigs for decompilation though so technically you do have enough memory.

[DeBugger]

Okay. Then I will try again. I cant upgrade my actual workspace to decomp, right? So I will copy all classes to a new...

[DeBugger]

My console send the error that it cant allocate ~3 GB.

[V0idWa1k3r]

Do you use 32bit java? What's the output of java -version if you type it into cmd?

[DeBugger]

java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) Client VM (build 25.151-b12, mixed mode, sharing)

[DeBugger]

If I remember right I have runned my pc on win8.1 and it showed up 64bit. Now on win10 it is showing up 32bit. However why

[DeBugger]

Now I use 64bit Java.

[DeBugger]

Hey guys,

is there a way to upgrade my DevWorkspace to DecompWorkspace without lost of my classes?

DeBugger

 

PS: Are Im allowed to use  the onKillEntity-code of the Zombie class? I would like to change from ZombieVillager to Cyborg (my mob). I have no idea how to let my mob create more Cyborgs without using the onKillEntity-method. Is that against the EULA of Mojang?  

Edited September 9, 2018 by DeBugger

[DeBugger]

Okay, thank you a lot? Yes, in regular I have for all builded versions a backup.

Edited September 9, 2018 by DeBugger

[DeBugger]

Do I issue the EULA of Mojang if I override the onKillEntity method by using the same Code? I only would Change the variables and the used Mobs. I also would add a few lines of own Code. Could anybody help me?
