[1.7.10] Mobs AI and Attributes

[American2050]

Hello forum.

 

So I'm coding a Mob and I'm having some problems with the attributes and AI for it.

 

For example, the first problem I'm having is that I need the mob to follow players to attack from a distance about, lets say 128 blocks.

 

So I have all this, but still seems not taking effect. Is there something I'm missing here?

Also, I made it "Giant" like a Giant Zombie, is there anything I should consider when coding a Mob like this? I added some code from the GiantZombie in Minecraft, not really sure what it does and if its really necessary.

Thanks for the help

 

The complete code is:

 

package com.mramericanmike.mymod.entity;

import net.minecraft.command.IEntitySelector;
import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.EntityLivingBase;

import net.minecraft.entity.ai.EntityAIWatchClosest;
import net.minecraft.entity.boss.IBossDisplayData;

	super(world);


	this.experienceValue = 150;
	this.captureDrops = true;
	this.setCanPickUpLoot(true);
	this.isImmuneToFire = true;
	this.getNavigator().setCanSwim(true);

	this.setHealth(this.getMaxHealth());
//        this.width = 3F;
//        this.height = 8F;
        this.addPotionEffect(new PotionEffect(Potion.resistance.id, 24000, 0));
        
        
        this.yOffset *= 4.0F;
        this.setSize(this.width * 4.5F, this.height * 5.5F);
        
        
        
        //AI
        
        
        this.tasks.addTask(0, new EntityAISwimming(this));
        this.tasks.addTask(1, new EntityAIWatchClosest(this, EntityPlayer.class, 128.0F));
        this.tasks.addTask(2, new EntityAIAttackOnCollide(this, 1.75D, true));
        this.tasks.addTask(3, new EntityAIMoveTowardsTarget(this, 1.75D, 128.0F));
        
        this.targetTasks.addTask(4, new EntityAINearestAttackableTarget(this, EntityLiving.class, 0, false, true, IMob.mobSelector));
        


}

    protected void applyEntityAttributes()
    {
        super.applyEntityAttributes();
        this.getEntityAttribute(SharedMonsterAttributes.followRange).setBaseValue(128.0D);
        this.getEntityAttribute(SharedMonsterAttributes.attackDamage).setBaseValue(100.0D);
        this.getEntityAttribute(SharedMonsterAttributes.maxHealth).setBaseValue(1000.0D);
        this.getEntityAttribute(SharedMonsterAttributes.movementSpeed).setBaseValue(1.75D);
        this.getEntityAttribute(SharedMonsterAttributes.knockbackResistance).setBaseValue(1.0D);
        
    }
    
    
    
    
    public float getBlockPathWeight(int p_70783_1_, int p_70783_2_, int p_70783_3_)
    {
        return this.worldObj.getLightBrightness(p_70783_1_, p_70783_2_, p_70783_3_) - 0.5F;
    }
    
    
    

    @Override
    protected boolean canDespawn()
    {
        return false;
    }
    
    @Override
    protected String getHurtSound()
    {
//        return "game.hostile.hurt";
    	Log.Debug("MyMob Hurt");
    	return null;
    }

    @Override
    protected String getDeathSound()
    {
//        return "game.hostile.hurt";
    	Log.Debug("MyMob Death");
    	return null;
    }
    
    @Override
    protected Item getDropItem()
    {
    	Log.Debug("MyMob Drops");
    	return ModItems.apple;
    	
    }
}

 

PS: If I'm trying to make a Boss, what attributes and AI do you recommend me to use?

ok dude, u need to realize that all this stuff is in vanilla mob classes. so you failed to the upmost extent.

 

you need to enable the ai..  which every other mob class in minecraft has (well pretty much).

	}

public boolean isAIEnabled() {

	return true;
}

 

and for getting ur boss bar?? look at wither or enderdragon code, seriously.

vanilla has everything you need.

 

so for the boss bar you have to make an onlivingupdate method, like this..

public void onLivingUpdate() {
	super.onLivingUpdate();

 

and to get the boss bar all you need is this line of code, which set the boss bar, believe it or not.

BossStatus.setBossStatus(this, true);

 

basically for the future. look at vanilla code first, and look for tutorials.

It will help you out ALLOT.

Also, I made it "Giant" like a Giant Zombie, is there anything I should consider when coding a Mob like this? I added some code from the GiantZombie in Minecraft, not really sure what it does and if its really necessary.

 

 

the witdth and the height sets the size of the hit box, a better way to do that might be this.setSize(3F, 8F)

For AI, I have some tutorials: http://jabelarminecraft.blogspot.com/p/minecraft-forge-1721710-custom-entity-ai.html

 

For attacking attributes, I have this tutorial: http://jabelarminecraft.blogspot.com/p/minecraft-forge-1721710-apply.html

 

For giant mobs, one of the main difficulties is the hit box, I think there are some limits to the size, at least in the height. This is due, I think, to the pathfinding -- it is hard for Minecraft to figure out how large hitboxes can move through terrain. In the giant entity I made, I think the maximum size I found that worked was setSize(1.0F, 4.5F).

BoonieQuafter-CrAfTeR Thanks a lot, yes I finally noticed I was missing that isAIEnabled()

Thanks also on the tips about the Boss Bar, that was coming after I figured the AI so thanks a lot on the tips for that aswell

 

Jabelar, thanks a lot, I'm going to take a look at yours tutorials.

Also thanks with the tips on how big the Hitbox should be, I think I made mine too big as for now, so I should probably start with the same dimensions the GiantZombie has and test from there
