Custom entity cant attack...

Recommended Posts

I added:

 

this.getAttributeMap().registerAttribute(SharedMonsterAttributes.attackDamage);

this.getEntityAttribute(SharedMonsterAttributes.attackDamage).setBaseValue(4.0D);

 

To applyEntityAttrivutes() but when it goes to attack something it just rubs against it :P

 

Here is the ai code:

 

public EntityBlockGuardianStone(World world) {

 

super(world);

 

this.setSize(0.85F, 0.91F);

 

this.getNavigator().setAvoidsWater(true);

this.getNavigator().setCanSwim(false);

this.tasks.addTask(0, new EntityAIAttackOnCollide(this, 1.0D, true));

        this.tasks.addTask(1, new EntityAIFollowOwner(this, 1.0D, 8.0F, 2.0F));

        this.tasks.addTask(2, new EntityAIPanic(this, 1.5D));

        this.targetTasks.addTask(0, new EntityAIOwnerHurtByTarget(this));

        this.targetTasks.addTask(1, new EntityAIOwnerHurtTarget(this));

        this.targetTasks.addTask(2, new EntityAIAttackOnCollide(this, 1.0D, true));

        this.setTamed(false);

       

}

The damage done during an attack is actually very convoluted in the Minecraft code.  It is done in the attackEntityAsMob() method which you need to override (it is inherited in EntityLivingBase class where it does nothing but update the last attacker)

 

In the EntityWolf class I think it does something like:

    @Override
public boolean attackEntityAsMob(Entity par1Entity)
    {
        int i = isTamed() ? 4 : 2;
        return par1Entity.attackEntityFrom(DamageSource.causeMobDamage(this), i);
    }

 

However that isn't really good coding because it should really call the super method to ensure the last attacker is updated and also it should get the damage value from the attribute instead of hard-coded as 2 (or 4 if tamed).

 

However, the weird thing is that I think the EntityLivingBase attackEntityAsMob() method has an error in it -- it has this.setLastAttacker(par1Entity) but that is backwards I think -- should be par1Entity.setLastAttacker(this).  Anyone else agree.

 

Anyway, since the wolf class seems to not care about setting last attacker and because it seems backwards to me, I guess just leave it out.  But normally you'd want to consider calling or copying the super method.

 

Overall, to get damage occurring you can modify the method to be something like:

    @Override
public boolean attackEntityAsMob(Entity par1Entity)
    {
        return par1Entity.attackEntityFrom(DamageSource.causeMobDamage(this), (float) getEntityAttribute(SharedMonsterAttributes.attackDamage).getAttributeValue());
    }

 

As you can see, this doesn't deal damage directly because it wants to let the entity that is hit fully process the attack (for example maybe it has hurt resistance in effect) before fully deciding the damage to deal.

 

Anyway, hope this helps.

Correction, previously the code I posted I put in the movementSpeed attribute when of course it should be the attackDamage attribute.  I've corrected it above.  I'll all PM you to make sure you are aware of the correction.

 

public boolean attackEntityAsMob(Entity par1Entity) {

 

this.attackTimer = 50;

 

        return par1Entity.attackEntityFrom(DamageSource.causeMobDamage(this), (float) getEntityAttribute(SharedMonsterAttributes.attackDamage).getAttributeValue());

       

}

    • Hello I'm looking for help launching minecraft through curseforge. I've scoured the Internet and can't seem to find anyone with a solution to my specific situation/fix that I haven't tried. I'll post the Curseforge debug Logs below. But basically I'm on a Laptop (Lenovo Legion Slim 7 2021) And the people I've seen with the most similar scenario and found a fix they always had an AMD graphics card and were missing the correct drivers, Well i have the Nvidia geforce RTX 3060 Laptop version with all the most updated drivers, I've reinstalled the drivers so that doesn't seem to me the problem. Also, minecraft will launch in vanilla and through another modloader called modrinth. So it doesn't feel like a Java error either but I don't no how to read this debug page so I'm looking for advice. Please help?!  
    • Hello. Basically I made a custom standalone util library (https://github.com/lolhol/Pathfinder3D) and want to use it with my mod. Although I have done the normal jit pack stuff (basically the tutorial on their website) the Minecraft crashes the second it starts saying that it cannot find the name of a class inside of my library. (When I remove the implement(<my library link thingy>) mc launches normally and does not crash (if I comment out the code that uses the custom lib)). Now then, is there a quick fix for this because all of the other questions that I found on this topic were trying to load another mod (again, not what I’m trying to do). Am I doing something wrong?

    • Hello, im kind of a newbie on creating mods, and i been trying to make simples mods so far, Right now, i'm creating a mod which detect an specific type of mob and kill it if reach a certain number, by far the mod is detecting the mob and counting them but at the time it reach the limit number, it don't do anything. The Game don't tweak, don't crash, just i't don't run the method i call, which is kill().   public InteractionResultHolder<ItemStack> use(Level pLevel, Player pPlayer, InteractionHand pUsedHand) { final var TotalCows = pLevel.getNearbyEntities(Cow.class, TargetingConditions.forNonCombat(), pPlayer, pPlayer.getBoundingBox().inflate(5)); if(pLevel.isClientSide){ if(pPlayer.getItemInHand(InteractionHand.MAIN_HAND).getItem() == this.asItem()){ if(!TotalCows.isEmpty()){ if(TotalCows.get(0).isAlive()){ TotalCows.get(0).kill(); } }else{ pPlayer.sendSystemMessage(Component.literal("No hay vacas")); } } } The sendSystemMessage is get triggered, and when i change the method .kill() by any other like send a message it got called, can i get some tips, and a clue of what i'm missing
    • UPD: I DID IT   @Override public void applyEffectTick(LivingEntity livingEntity, int pAmplifier) { Level level = livingEntity.level(); if (!level.isClientSide()) { Holder<DamageType> entropyHolder = level .registryAccess() .registryOrThrow(Registries.DAMAGE_TYPE) .getHolderOrThrow(GTDamageTypes.ENTROPY_KEY); livingEntity.hurt(new DamageSource(entropyHolder), 1); } super.applyEffectTick(livingEntity, pAmplifier); }
