My code : ```java
public class TestMob extends EntityGiantZombie {
public TestMob(final World w, String name, float health, double speed, double damage, double range, boolean grief, boolean projectile) {
super(EntityTypes.G, ((CraftWorld)w).getHandle());
}

protected void initPathfinder() {
    this.bQ.a(1, new PathfinderGoalMeleeAttack(this, 0.5, true));
    this.bQ.a(2, new PathfinderGoalNearestAttackableTarget<>(this, EntityHuman.class, false));
}

public TestMob spawn(final Location loc) {
    this.setLocation(loc.getX(), loc.getY(), loc.getZ(), loc.getYaw(), loc.getPitch());
    ((CraftWorld)loc.getWorld()).getHandle().addEntity(this, CreatureSpawnEvent.SpawnReason.CUSTOM);
    return this;
}

}```

#

And the giant is removed from the world
anyone know why?

Why are you using unmapped

eager cape Feb 22, 2024, 7:34 PM

#

why not?

dusk drum Feb 22, 2024, 7:34 PM

#

A pain to write and a pain to read

eager cape Feb 22, 2024, 7:35 PM

#

bQ = path finders

#

G = Giant

honest sail Feb 22, 2024, 7:35 PM

#

just use mapped

eager cape Feb 22, 2024, 7:36 PM

#

that's not going to solve my problem

white belfry Feb 22, 2024, 7:41 PM

#

Sorry no one now adays wants to deal with obfuscated you're young to be more likely to get help if you switch

#

Not to mention this is NMS and is not an API error

#

Also you're on an outdated version even if it was an API error :P

eager cape Feb 22, 2024, 7:42 PM

#

i used api from https://repo.codemc.io/repository/nms/

#

how can it be obsolete

#

and I don't see the problem that there are 2 pieces of obfuscated code

#

If you don't know how to help me, say so instead of blaming me.

#

eager cape i used api from ``https://repo.codemc.io/repository/nms/``

Yes using an illegal code hosting repository pepeLaugh 💯

#

Anyways you're suffering from a null pointer considering none of your code shows up in the stack trace you forgot to set some value

#

Easiest method is to reverse engineer and figure out what var0 is

#

I reccomend you legally obtain and use the NMS code as given by BuildTools

eager cape Feb 22, 2024, 7:52 PM

#

white belfry Yes using an illegal code hosting repository <a:pepeLaugh:611908299536859147> 💯

oh I didn't know that

#

I'll try thank

#

white belfry I reccomend you legally obtain and use the NMS code as given by BuildTools

You can decompile the given jars in your .m2 to look through the code alternatively you can look at CraftBukkit

Here is my code with the remapped version : ```java
import net.minecraft.world.entity.EntityType;
import net.minecraft.world.entity.ai.goal.MeleeAttackGoal;
import net.minecraft.world.entity.ai.goal.target.NearestAttackableTargetGoal;
import net.minecraft.world.entity.monster.Giant;
import net.minecraft.world.entity.player.Player;
import org.bukkit.Location;
import org.bukkit.World;
import org.bukkit.craftbukkit.v1_17_R1.CraftWorld;
import org.bukkit.event.entity.CreatureSpawnEvent;

public class TestTitan extends Giant {
public TestTitan(final World w, String name, float health, double speed, double damage, double range, boolean grief, boolean projectile) {
super(EntityType.GIANT, ((CraftWorld)w).getHandle());
}

protected void initPathfinder() {
    this.goalSelector.addGoal(1, new MeleeAttackGoal(this, 0.5, true));
    this.goalSelector.addGoal(2, new NearestAttackableTargetGoal<>(this, Player.class, false));
}

public TestTitan spawn(final Location loc) {
    setPos(loc.getX(), loc.getY(), loc.getZ());
    ((CraftWorld)loc.getWorld()).getHandle().addEntity(this, CreatureSpawnEvent.SpawnReason.CUSTOM);
    return this;
}

}

#

i still have this error

#

which crashes the server

eager cape Feb 22, 2024, 9:15 PM

#

according to the logs the error occurred at line 33

#

var0 is the goal target of the PathfinderGoalMeleeAttack

#

white belfry Feb 22, 2024, 9:21 PM

#

The given entity being passed to that function is null somehow

#

Weird have you tried looking at how mojang uses the goal

eager cape Feb 22, 2024, 9:23 PM

#

not yet, I'll look later

#

but from what I see it really comes from Minecraft and not from my plugin

#

just one question, does PathfinderGoalMeleeAttack still need NearestAttackableTargetGoal to work?

#

because I just saw that I register PathfinderGoalMeleeAttack in first position in the goalSelector. Maybe this is the cause

white belfry Feb 22, 2024, 9:29 PM

#

I'm not very experienced in goals I'd say if they are used in conjunction with eachother naturally I'd assume that'd be the case

#

I'd assume attackable goal finds a target and pathfinder walks towards the target?

eager cape Feb 22, 2024, 9:30 PM

#

yes I think the MeleeAttackGoal needs NearestAttackableTargetGoal because the MeleeAttackGoal does not take any entity type as parameter

#

i will try to put NearestAttackableTargetGoal in first position

#

AND IT'S WORKK!!!! no more errors

#

oh i'm so happy

#

I spent so much time on this bug lol
