Quote from Jesuitical

Hey, how are you doing?

I've been using your tutorials, and they've helped so much. They're great, thanks for making them.

I've run into a little problem, though. I am making, well updating, a mod of mine called Boss Mobs: Yeti. It adds Bosses to Minecraft, this particular part of the series adding the Yeti.

Well, everything was fine before, aside from some bugs, which is which this update was for. In the original, everything seemed to be spawning in the desert instead of the snow biomes I designated them to, and there were more than I had planned spawned in one area. So with this new version, I fixed that by copying some code from the Ghast so that it checks the biome and makes sure there is only one.

Now that everything is changed, I ran it from Eclipse and everything was perfect. As soon as I reob and try in actual Minecraft, though, nothing spawns at all, nor can I spawn it with SPC, even in proper snow biomes.

Here is the code that I use.

mod_Yeti

package net.minecraft.src;
import java.util.Map;
public class mod_Yeti extends BaseMod
{
	  
		public void load()
		{	  
				ModLoader.registerEntityID(EntityYeti.class, "Yeti", ModLoader.getUniqueEntityId());
				ModLoader.addSpawn(EntityYeti.class, 1, 1, 1, EnumCreatureType.creature);
				ModLoader.registerEntityID(EntityHunter.class, "Hunter", ModLoader.getUniqueEntityId());
				ModLoader.addSpawn(EntityHunter.class, 3, 3, 6, EnumCreatureType.creature);
		}
	  
		public void addRenderer(Map map)
		{
			 //Render and Model
			
				map.put(EntityYeti.class, new RenderBiped(new ModelBiped(), 0.5F));
				map.put(EntityHunter.class, new RenderBiped(new ModelBiped(), 0.5F));
			  
				//Spawning
				ModLoader.addSpawn(EntityYeti.class, 2, 1, 4, EnumCreatureType.monster,  new BiomeGenBase[]
				{
						BiomeGenBase.taiga,
						BiomeGenBase.frozenOcean,
						BiomeGenBase.frozenRiver,
						BiomeGenBase.iceMountains,
						BiomeGenBase.icePlains,
						BiomeGenBase.taigaHills
				});
			  
				ModLoader.addSpawn(EntityHunter.class, 2, 1, 4, EnumCreatureType.monster,  new BiomeGenBase[]
				{
						BiomeGenBase.taiga,
						BiomeGenBase.frozenOcean,
						BiomeGenBase.frozenRiver,
						BiomeGenBase.iceMountains,
						BiomeGenBase.icePlains,
						BiomeGenBase.taigaHills
				});
		}
	  
		public String getVersion()
		{
				return "1.2.5";
		}
}

EntityYeti

package net.minecraft.src;
import java.util.Random;
public class EntityYeti extends EntityMob
{
		public EntityYeti(World world)
		{
				super(world);
				texture = "/yeti.png";
				moveSpeed = 0.5F;
				targetTasks.addTask(2, new EntityAINearestAttackableTarget(this, net.minecraft.src.EntityPlayer.class, 16F, 0, true));
				targetTasks.addTask(2, new EntityAINearestAttackableTarget(this, net.minecraft.src.EntityHunter.class, 16F, 0, true));
		attackStrength = 10; //take this line out if this class doesn't extend EntityMob.
		}
		public int getMaxHealth()
		{
				return 25;
		}
		protected String getLivingSound()
		{
				return "mob.zombie";
		}
		protected String getHurtSound()
		{
				return "mob.zombiehurt";
		}
		protected String getDeathSound()
		{
				return "mob.zombiedeath";
		}
	  
		/**
		 * Returns the item ID for the item the mob drops on death.
		 */
		protected int getDropItemId()
		{
			return Block.ice.blockID;
		}
		/**
		 * Drop 0-2 items of this living's type
		 */
		protected void dropFewItems(boolean par1, int par2)
		{
			int i = rand.nextInt(3) + rand.nextInt(1 + par2);
			for (int j = 0; j < i; j++)
			{
				dropItem(Block.ice.blockID, 1);
			}
			i = rand.nextInt(3) + 1 + rand.nextInt(1 + par2);
			for (int k = 0; k < i; k++)
			{
				if (isBurning())
				{
					dropItem(Item.diamond.shiftedIndex, 1);
				}
				else
				{
					dropItem(Item.snowball.shiftedIndex, 4);
				}
			}
		}
	  
	
	  
		protected boolean canDespawn()
		{
				return false;
		}
		/**
		 * Checks if the entity's current position is a valid location to spawn this entity.
		 */
		public boolean getCanSpawnHere()
		{
			return rand.nextInt(20) == 0 && super.getCanSpawnHere() && worldObj.difficultySetting > 0;
		}
		/**
		 * Will return how many at most can spawn in a chunk at once.
		 */
		public int getMaxSpawnedInChunk()
		{
			return 1;
		}
	  
}

I also added a new mob to it, Hunters. They are supposed to attack the Yetis, and the Yetis are supposed to attack them. But they don't, not even in eclipse.

EntityHunter

package net.minecraft.src;
import java.util.Random;
public class EntityHunter extends EntityMob
{
		public EntityHunter(World world)
		{
				super(world);
				texture = "/hunter.png";
				moveSpeed = 0.5F;
				targetTasks.addTask(2, new EntityAINearestAttackableTarget(this, net.minecraft.src.EntityYeti.class, 16F, 0, true));
		attackStrength = 4; //take this line out if this class doesn't extend EntityMob.
		}
		public int getMaxHealth()
		{
				return 20;
		}
		protected String getLivingSound()
		{
				return "mob.villager.default";
		}
		protected String getHurtSound()
		{
				return "mob.villager.defaulthurt";
		}
		protected String getDeathSound()
		{
				return "mob.villager.defaultdeath";
		}
		protected int getDropItemId()
		{
				return Item.ingotGold.shiftedIndex;
		}
	  
		protected boolean canDespawn()
		{
				return false;
		}
	  
		public ItemStack getHeldItem()
		{
				return defaultHeldItem;
		}
			  
				static
		{
				defaultHeldItem = new ItemStack(Item.swordStone, 1);
		}
			  
		private static final ItemStack defaultHeldItem;
	  
		/**
		 * Checks if the entity's current position is a valid location to spawn this entity.
		 */
		public boolean getCanSpawnHere()
		{
			return rand.nextInt(20) == 0 && super.getCanSpawnHere() && worldObj.difficultySetting > 0;
		}
}

Yes, this was directed to the creator of these tutorials, but if you know the problem and can respond before him (ASAP), please go ahead, this has been frustrating me for hours.

Thanks,

Jesuitical.

worldObj.difficultySetting > 0

Quote from ampenergy34

ok i have a problem that i need answered right away. i have the mod coded right but it keeps crashing because it cant load the image and i coded it like the code on the tutorial. here is my code.

package net.minecraft.src;
public class mod_ObsidianApple extends BaseMod
{
		public static final Item obsidianapple = new ItemFood(124, 20, 60F, true).setItemName("Obsidian Apple");
	  
		public void load()
		{
				obsidianapple.iconIndex = ModLoader.addOverride("/gui/items.png", "/mcp/eclipse/Client/bin/obsidianapple.png");
				ModLoader.addName(obsidianapple, "Obsidian Apple");
				ModLoader.addRecipe(new ItemStack(obsidianapple, 1), new Object [] {"@@@", "@#@", "@@@", Character.valueOf('#'), Item.appleRed, Character.valueOf('@'), Block.obsidian});
		}
	  
		public String getVersion()
		{
				return "1.2.5";
		}
}

obsidianapple.iconIndex = ModLoader.addOverride("/gui/items.png", "/obsidianapple.png");

(Didn't want to quote all that)

I really hope that was the problem. Thank you

Also, could you tell me why they won't attack each other and why sometime the mod bugs and they only spawn in deserts. If not, that's fine.

targetTasks.addTask(3, new EntityAINearestAttackableTarget(this, net.minecraft.src.EntityHunter.class, 16F, 0, true));

Quote from Jesuitical

Okay, I'll try.

The Hunter mobs spawn in the snow areas like they are supposed to, but also a lot in the desert. Yeti flat out only spawns in the desert.

Unless I misunderstood what you said, the problem still persists.

hello techguy, i have followed your tut on making an achievement but i want people to get the achievement when they collect redstone. just like when you mine diamond ore, pick up diamonds and get the achivement. How do i do that?

Are you playing on peaceful? If you are then neither mob will spawn because of this:

worldObj.difficultySetting > 0

mcp/eclipse/Client/bin is the default folder for images, so you make a path from that location. If you have your image in that directory, then your code just needs to say:

Quote from Koadmaster

If you look at this chunk of code:

	protected int getDropItemId()
	{
		if (isBurning())
		{
			return Item.porkCooked.shiftedIndex;
		}
		else
		{
			return Item.porkRaw.shiftedIndex;
		}
	}

(That is from entity pig) you can see the "if (isBurning())" line followed by "return Item.porkCooked.shiftedIndex;" I think you can just put your bacon right under that... I think


just put in one "int =" and you don't need the: "world.setBlockWithNotify(i, j, k, cloth);" eather (just the ones with metadata), and you need to change the (i, j, k,)'s with some + or - as that is were the block will spawn. example of code:

package net.minecraft.src;

import java.util.Random;

public class WorldGenArabHouse extends WorldGenerator
{
		public WorldGenArabHouse()
		{
		}

		public boolean generate(World world, Random desert, int i, int j, int k)
		{
				int cloth = Block.cloth.blockID;

				world.setBlockAndMetadataWithNotify(i, j, k, cloth, 1);
				world.setBlockAndMetadataWithNotify(i, j, k +1, cloth, 1);
				world.setBlockAndMetadataWithNotify(i, j, k +2, cloth, 3);
				world.setBlockAndMetadataWithNotify(i, j, k +3, cloth, 4);  
				world.setBlockAndMetadataWithNotify(i, j, k +4, cloth, 5);

				return true;
		}  
}

and that should give you a line of different colored wool
