LegendTriforce, how do I make my mob drop a custom item I made? Here's the code for the mod_ file for the item I made:

package net.minecraft.src;

public class mod_AcidItem extends BaseMod
{
public mod_AcidItem()
   {
    ModLoader.AddName(acidItem, "acid");        
   } 
public static final Item acidItem;
 
static
    {
      acidItem = (new ItemAcid(4001)).setIconIndex(ModLoader.addOverride("/gui/items.png", "/item/alienacid.png")).setItemName("acidAlien");
         }
		 
public String Version()
    {
      return "1";
    }
	
	}

How do I tell which item name is the correct one to put in the mob's drop code? I keep getting Cannot find symbol errors when I recompile.

First of all, that won't work because what you put in

.setItemName

has to be the same as the name you put in

public static final

! To make the mob drop your item you have to make it so that where it shows the item to be dropped you put

return (your mod file name:mod_AcidItem).(your item:acidItem).shiftedIndex

!

How do you make it so that the mob has more health?

I'm thinking there's a health variable in the entity file that lets you do that.

Yup, found it, it's in EntityMob!

Reobf error :sad.gif:

I would most likely reinstall mcp, then try recompiling and reobfuscating again. That should fix your problem. Either that or setting the permissions so the computer is allowed to access the folder.

My mob still doesn't hold a sword there are no errors anywhere! This is my code:

package net.minecraft.src;

import java.util.List;
import java.util.Random;

// Referenced classes of package net.minecraft.src:
//            EntityZombie, World, NBTTagCompound, EntityPlayer, 
//            AxisAlignedBB, Entity, Item, ItemStack

public class EntityBlackKnight extends EntityZombie
{

    public EntityBlackKnight(World world)
    {
        super(world);
        texture = "/StrongJoshua/BlackKnight.png";
        moveSpeed = 0.5F;
        attackStrength = 5;
        health = 30;
    }

    public void writeEntityToNBT(NBTTagCompound nbttagcompound)
    {
        super.writeEntityToNBT(nbttagcompound);
    }

    public void readEntityFromNBT(NBTTagCompound nbttagcompound)
    {
        super.readEntityFromNBT(nbttagcompound);
    }


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


    protected String getLivingSound()
    {
        return "mob.zombie.zombie";
    }

    protected String getHurtSound()
    {
        return "mob.zombie.zombiehurt";
    }

    protected String getDeathSound()
    {
        return "mob.zombie.zombiedeath";
    }

    protected int getDropItemId()
    {
        return mod_Carbon.carbon.shiftedIndex;
    }

    public ItemStack getHeldItem()
    {
        return defaultHeldItem;
    }

    private static final ItemStack defaultHeldItem;

    static 
    {
        defaultHeldItem = new ItemStack(Item.swordGold, 1);
    }
}

I don't understand i'm doing everything right I'm trying to make a knight heres my source code for the Entity File : package net.minecraft.src;

public class EntityKnight extends EntityCreature
{

public EntityKnight(World world)
{
super(world);
//This is the texture for your mob
texture = "/mob/Knight.png";
}

protected int getDropItemId()
{
//This is the item your mob will drop
return Item.plateChain.shiftedIndex;
}
}


And here it is for the mod_knight file: package net.minecraft.src;

import java.lang.reflect.Method;

public class mod_Knight extends BaseMod
{
public mod_Knight()
{
}

public void AddEntityID()
{
//This defines your entity. Class name, entity name, and then the entity ID.
EntityList.addMapping(EntityKnight.class, "Knight", ModLoader.getUniqueEntityId());
//This adds your mob to the spawn list.
spawnlist.addCreaturesToSpawnList("Surface biomes", EntityKnight.class);
package net.minecraft.src;

import java.lang.reflect.Method;
import java.util.Map;

public class mod_Knight extends BaseMod
{

public String Version()
{
//not sure exactly what this does, but I know that you can write pretty much anything you want in there.
return "mod_Knight version 1.1 [1.7.2]";
}
public mod_Knight()
{
ModLoader.RegisterEntityID(EntityKnight.class, "Knight", ModLoader.getUniqueEntityId());
ModLoader.AddSpawn(EntityKnight.class, 8, EnumCreatureType.creature);//not sure what the 8 does, play around with it if you want
}
//this part gives your mob a human model. This part is necessary if you want your mob to be able to carry stuff.
public void AddRenderer(Map map)
{
map.put(EntityKnight.class, new RenderBiped(new ModelBiped(), 0.5F));
}
}

}
}

Reached end of file while parsing means that you either have an extra brace { or are missing one. That might also fix your other error.

Ok, how do I add to this code so that the predator attacks aliens like the wild wolf attacks sheep?
Code:

import java.util.List;

package net.minecraft.src;

        super(world);
        angerLevel = 0;
        randomSoundDelay = 0;
        texture = "/mob/Predator.png";
        moveSpeed = 0.5F;
        attackStrength = 5;
        isImmuneToFire = true; //Self-explanatory. Makes it immune to fire and magma (or not)
    }

    public void onUpdate()
    {
        moveSpeed = playerToAttack == null ? 0.5F : 0.95F;
        if(randomSoundDelay > 0 && --randomSoundDelay == 0)
        {
            //In line below: pick angry sound (when mob is punched and the pack gets mad)
            worldObj.playSoundAtEntity(this, "mob.zombiepig.zpigangry", getSoundVolume() * 2.0F, ((rand.nextFloat() - rand.nextFloat()) * 0.2F + 1.0F) * 1.8F);

LegendTriForce and StrongJoshua, got any ideas?

How about how to tame them?

ok im in 1.0.0 trying to make it so animles spawn like they did in 1.7 wat .java do i edit

WHERE IS 303'S SPAWNER LIST? I searched like every comment in the previous tutorial, I searched the forums, I cant find it.. Is it like an API or just a list of the mobs to be spawned?

Wait, I think I found it... edit
Still cant figure out how to use it... I guess this tutorial is out of date?:
http://mcp.ocean-lab...wnlist_mappings
It tells me to use files that arent there...
And the link the forum gives me are to a website that was shut down, so I am now frustrated. How am I supposed to get it?? Is there maybe a tutorial that isnt using it??
