Great tutorial, having a problem though.

If I decompile a clean minecraft.jar - then I get no errors at all and all the .java files are placed into /src/ folder.

When I follow these steps:

1. Add Basemod.class, ModTexture.class and Modloader.class to your clean minecraft.jar.
2. Add spawnlist.class to your minecraft.jar.

(using mcp29a, Modloader ver4 and spawnlist 1.3v1)

I get a ton of hunk errors and /src/ folder is empty.
I also tried the updates to the /conf/reob.conf file and still got the same hunk errors.

Am I missing something?

i get the same error. been searching for it on internet. no luck =(
help us! ****

Being rude won't get you help, I don't gain from this thread at all, friend.

To everyone having issues, I'm sorry to say but I'm not really huge into the modding world anymore, this tutorial seems to be quite a bit behind the newest versions of modloader and spawnlist, both of which have changed quite a bit. The OP has been updated with all the fixes I know of, and if anyone comes forward with the answers people need I will update the OP with the fixes, but I can not and will not promise to keep up with modloader and spawnlist's every change, I simply don't have the time. Sorry.

Ok, first of all did you put modloader into the minecraft.jar file before decompiling? If so that might be causing some of your problems, you want to start with a clean slate. When you downloaded the MCP files inside there should be a text file named readme_ml, if you read that it will explain how to decompile correctly like above ^^, once you do that get back to me and tell me how it went/if you have another problem. Also I'm having the same trouble with your 3rd error.

EVERY ONE WHO IS GETTING THE Spawnlist error go to GRAB THE LATEST MAPPINGS

cant find the .class spawnlist thingy???

Go to the first .class make space for a new line and put in the Big box.
CTRL + C And CTRL + V at the new line. This Should help!

Still have the same error.

I get this error:

I added the latest spawnlist mapping to my minecraft.rgs, yet it still gave me that error! Am I not adding the mappings properly or something?

For some reason when I attack my mob it sends me flying away, it knocks me back and does constant damage, instead of just when I'm attacked.
Here's the code:

package net.minecraft.src;

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

public class EntityCivilian extends EntityCreature
{

   public EntityCivilian(World world)
   {
      super(world);
      //This is the texture for your mob
      texture = "/mob/civilian.png";
      attackStrength = 5;
      moveSpeed = 0.5F;

      angerLevel = 0;
   }

        {
            attackTime = 20;
        }
            entity.attackEntityFrom(this, attackStrength);
    }

    {

        if(randomSoundDelay > 0 && --randomSoundDelay == 0)
        {
            worldObj.playSoundAtEntity(this, "step.cloth", getSoundVolume() * 2.0F, ((rand.nextFloat() - rand.nextFloat()) * 0.2F + 1.0F) * 1.8F);
        }
                super.onUpdate();
        if(worldObj.difficultySetting == 0)
        {
            setEntityDead();
        }
    }

            return false;
        }
        int i = MathHelper.floor_double(posX);
        int j = MathHelper.floor_double(boundingBox.minY);
        int k = MathHelper.floor_double(posZ);
        int l = worldObj.getBlockId(i, j - 1, k);
        return worldObj.difficultySetting > 0 && worldObj.checkIfAABBIsClear(boundingBox) && worldObj.getCollidingBoundingBoxes(this, boundingBox).size() == 0 && !worldObj.getIsAnyLiquid(boundingBox);
    }

    public void writeEntityToNBT(NBTTagCompound nbttagcompound)
    {
        super.writeEntityToNBT(nbttagcompound);
        nbttagcompound.setShort("Anger", (short)angerLevel);
    }

    public void readEntityFromNBT(NBTTagCompound nbttagcompound)
    {
        super.readEntityFromNBT(nbttagcompound);
        angerLevel = nbttagcompound.getShort("Anger");
    }

        }

    }

    {

    protected String getHurtSound()
    {
        return "damage.hurtflesh";
    }

    {
        return "random.breath";
    }

    public void func_21077_o()
    {
        dropItem(Item.swordSteel.shiftedIndex, 1);
    }
    
    public ItemStack getHeldItem()
    {
        return defaultHeldItem;
    }

    private int angerLevel;
    private int randomSoundDelay;
    private static final ItemStack defaultHeldItem;

    static 
    {
        defaultHeldItem = new ItemStack(Item.swordSteel, 1);
    }   
   
   protected int attackStrength;
}

What would be causing this?

nice

I dont have anything in my final_out/minecraft folder.
halp?

EDIT: also i dont think i listed every file for step 16. im not sure what to put there all i put is mod_Zombie and thats it

EDIT 2: i did it again and i get this:

*** Minecraft Coder Pack Version 2.9 ***
MCP 2.9 running in C:\Users\toshiba\Desktop\L4D Zombie
Compiling Minecraft
sources\minecraft\net\minecraft\src\ModLoader.java:525: not a statement
        exception;
        ^
1 error
*** minecraft_server.jar was not found, skipping
=== MCP 2.9 recompile script finished ===
Press any key to continue . . .

and i checked every file to see for capitalization errors and spelling errors and nothin. i think my error was that it asked me if i wanted to replace entitylist with the entitlylist already in mcp, i put yes.. so any help?

Im SO close to accomplishing the "getting them on the map" part of the development of my mod :happy.gif:

th nks to these tutorials.

one problem though, I've created two mobs. one of them is visible on the map in game and the other is not. I can spawn the second one with SSP commands and see its shadow but not its body texture
in attempting to fix this I have:

went over the coding 0var 9,000 times
made sure its in the minecraft.jar file in the mobs folder
made sure the png files were sized and named correctly (they are only just recolors of each other)

what else can I do? here is my mod_mob.class

package net.minecraft.src;

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

public class mod_stonit extends BaseMod
{
  public String Version()
    {
        return "mod_stonit version 0.3";
    }
    public mod_stonit()
    {
       ModLoader.RegisterEntityID(Entitystonit.class, "Stonit", ModLoader.getUniqueEntityId());
       spawnlist.add("Surface biomes", spawnlist.CREATURE, new Object[] {"Stonit", Entitystonit.class});

       ModLoader.RegisterEntityID(Entitystonitb.class, "BlueStonit", ModLoader.getUniqueEntityId());
       spawnlist.add("Surface biomes", spawnlist.CREATURE, new Object[] {"BlueStonit", Entitystonitb.class});

}
          public void AddRenderer(Map map)
    {
        map.put(Entitystonit.class, new Renderstonit(new Modelstonit(), 0.5F));
        map.put(Entitystonitb.class, new Renderstonitb(new Modelstonitb(), 0.5F));

    }
}

how would i go about making an npc check the players hand for a block ID instead of a item id

FINALLY got it all compiled with no problems (Thanks to many of you), but I can't seem to find my mob anywhere. Not in test_game or if I reobf and place the class files into minecraft.jar, I've made sure I have the textures in the right place so can anyone help?

Any tips on how to add idle, death, and hurt sounds to the NPCs? I've got the sounds in the right format, I just don't know what code to implement.

Yes and I will add it to the OP at some point. put this in EntityYourmob

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

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

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

replace "mob" with the name of the folder your sounds are in, and after the period comes the name of the sound. if you have a couple different sounds for each thing, just name them the same with 2, 3, 4, etc. that should work. anyways the folder path should be .minecraft/resources/mod/sound/yourfolder.

could you tell me please how to add sounds to my mobs ? they are not modloader heres the link:

viewtopic.php?f=1032&t=214673&p=3097638#p3097638



please help...

i added the sounds but when i go to game i dont hear them help me ! im using normal mob with no modloader and i used your code what should i do help please what names should i put and in which folder ? if not using modloader?

I had that same problem man.

You need to do this:

Quote from Club559 »

For all of you getting problems with default ModLoader functions:
Latest mappings for ModLoader v5
And for those of you with spawnlist problems:
Latest mappings for spawnlist

Dont' let the "Spawnlist 1.2_02v2 for MCP 1.7+" fool you either. It actually works even though it says it's for older versions.

Far out. My first mob mod! :biggrin.gif:

Omg thanks! It works! Just copy your template, use the Modloader and Spawnlist mappings, and rename the spawnlist line in mod_****.Java, and you finished! Yay :DDDDDD
