XTremity's modding tutorials

Within the minecraft 1.1 update barely any source code was changed within modding, this will make it easier for you to update your mods, to update them get the new mcp, but dont erase your old one, and follow the tutorial below, put your scripts into the new mcp src\minecraft\net\minecraft\src folder and recompile, this should give you no errors, or atleast not many.

The armour tutorial was fixed and is now hopefully usable to the entire community.

Setting up MCP with modloader

Spoiler

Things you need for it:

A brain(Rented brains are ok)
A text editor
MCP
Modloader
7Zip/Winrar

1. Assuming you have already installed JDK we can get onto setting up mcp, goto Here and extract those files to a folder on the desktop.

2. Download modloader from Here and leave that open.

3. Get a clean minecraft bin folder and put the clean minecraft bin folder into the jars folder which is located inside your mcp folder.

4. Goto your clean bin folder and open your minecraft.jar, drag the files from the modloader rar file into the minecraft.jar and delete META-INF.

5. Go back to the mcp folder and run decompile.bat and it should decompile it correctly.

(If it says something like "2 HUNKS OUT OF 2 FAILED" don't worry, it doesn't mean anything!)

You have now set up mcp!

Recipes tutorial

Spoiler

Many people have been asking about recipes so heres a tutorial.
Where it says this:

ModLoader.AddRecipe(new ItemStack(Namehere, 1), new Object[] { 
"###", "###", "###", Character.valueOf('#'), Item.redstone
});  

This is the recipe for your item/block, if you want it to be a recipe where it uses a custom item/block do this:

ModLoader.AddRecipe(new ItemStack(BlockNamehere, 1), new Object[] { 
"###", "###", "###", Character.valueOf('#'), ItemNamehere
});  

or

ModLoader.AddRecipe(new ItemStack(ItemNamehere, 1), new Object[] { 
"###", "###", "###", Character.valueOf('#'), BlockNamehere
});

        }
    }   
}

1. Where it says mod_Namehere, change that to your mod name.
2. Where it says Namehere, change that to your block name.
3. Where it says:

for(int i = 0; i < 20; i++)

change the 20 to the rarity of your ore.
4. Where it says:

int randPosY = rand.nextInt(64);

change the 64 to the height above bedrock where you want to find it.
5. Where it says:

(new WorldGenMinable(mod_Namehere.Namehere.blockID, 12)

change the 12 to the maximum vein size of your ore.

Furnace recipe tutorial

Spoiler

To add a smelting recipe add this into load():

ModLoader.AddSmelting(mod_Namehere.Namehere.shiftedIndex, new ItemStack(mod_Namehere.Namehere2, 1));

This is changeable to use items to smelt instead:

ModLoader.AddSmelting(mod_Namehere.Namehere.BlockID, new ItemStack(mod_Namehere.Namehere2, 1));

1. Same as before, change mod_Namehere to the name of your mod.
2. Change Namehere to your item/block name that will be smelted.
3. Change the 1 at the end to the amount made.
4. Finally change Namehere2 to the name of your output item/block.
Hope that helped you.

Custom mob tutorials

Spoiler

Many have asked for a custom mob tutorial, so im gonna split it into two parts to make it easier for both me and you. You will need a program called techne which you can get from here: Techne

Modelling your custom mob

Spoiler

Ok to start of with download and install techne from above and launch it.
You should get something like this:


Now these lines below show you the functions of the start up screen:


The red line shows the name of your project, this can be anything, it doesn't matter.
The blue line shows you the bases that you can choose from, and by the way for the ones who dont know what biped means its just a minecraft character, well in techne that is.
The green lines are the texture sizes, you may need to change this depending on the size of your model.

Once you've created your project you should go to the editing screen, the lines show you the different tools you can use:


The black line is the button you have to press to make a new shape(cube).
The purple line is your preview of the texture of your current model.
The red line is the name of your current shape.
The blue line is the dimensions (size) of your current shape in pixels.
The green line shows the position of your shape.
The yellow line shows the offset of your current shape.
The light purple line shows the rotation of your shape.
The teal line shows:
The load texture button, self explanatory.
The delete box button, it deletes the current shape.
The copy and paste buttons, they copy and paste shapes.

And also below the Offset is the Texture offset which makes the current shapes texture move according to where you want it to be.

After you have finished modelling you have a completed model, heres the one i made earlier:



Thats the finished tutorial for your custom mob model, be sure to save it, we will need it later, and also you will need the texture for the next part.

Coding your custom mob

Spoiler

Ok we will need the basic mod_Namehere and the EntityNamehere from the basic human mob tutorial but change them a bit. So mod_Namehere would change to:

package net.minecraft.src;

public class mod_Namehere extends BaseMod
{
   public String getVersion()
   {
       return "1.0.0";
   }
   
   public mod_Namehere()
   {
      ModLoader.RegisterEntityID(EntityNamehere.class, "Namehere", 117);
   }

   public void load()
   {   
   }

   public void AddRenderer(Map map)    
   {          
      map.put(EntityNamehere.class, new RenderNamehere(new ModelNamehere(), 0.5F));
   }
}

So what you want to do is change all of the Namehere's to the name of your mod n mob stuff, and do most of the things you did in the human mob tutorial.

The EntityNamehere stays the same from the first tutorial so heres the code for it:

package net.minecraft.src;

public class EntityNameHere extends EntityAnimal
{
    public EntityNamehere(World world)
    {
        super(world);
        texture = "/tutorial/Namehere.png";
        moveSpeed = 0.5F;
    } 
	
	public void writeEntityToNBT(NBTTagCompound nbttagcompound)
    {
        super.writeEntityToNBT(nbttagcompound); // this saves the mob to disk, so it can be loaded later
    }

    public void readEntityFromNBT(NBTTagCompound nbttagcompound)
    {
        super.readEntityFromNBT(nbttagcompound); // this retrieves saved data about the mob from the hard drive
    }
	
	protected boolean canDespawn()
    {
		return false;
    }

    protected int getDropItemId()
    {
        return 0;
    }
	
   public int getMaxHealth()

       return 12;
   }
	
    protected EntityAnimal func_40145_a(EntityAnimal entityanimal)
    {
        return new EntityNamehere(worldObj);
    }
}

Do the same as you did in the human mob tutorial.

Now we need a RenderNamehere and a ModelNamehere, we can generate the ModelNamehere from our techne model, so load up your save in techne, goto file - export as - java and export it to somewhere where you know you can find it, then move it in with the rest of your files.
Warning: The exporting may not be perfect so go into the Model file and see if theres any errors.
My Model file would be:

// Date: 2/14/2012 8:58:40 AM
// Template version 1.1
// Java generated by Techne
// Keep in mind that you still need to fill in some blanks
// - ZeuX

}

The RenderNamehere is simple, ill give it to you:

public class RenderNamehere extends RenderLiving
{

    public RenderNamehere(ModelBase modelbase, float f)
    {
        super(modelbase, f);
    }

    public void renderCow(EntityNamehere entitynamehere, double d, double d1, double d2, 
            float f, float f1)
    {
        super.doRenderLiving(entitynamehere, d, d1, d2, f, f1);
    }

    public void doRenderLiving(EntityLiving entityliving, double d, double d1, double d2, 
            float f, float f1)
    {
        renderCow((EntityNamehere)entityliving, d, d1, d2, f, f1);
    }

    public void doRender(Entity entity, double d, double d1, double d2, 
            float f, float f1)
    {
        renderCow((EntityNamehere)entity, d, d1, d2, f, f1);
    }
}

All you have to do is change the Namehere's and nothing else.

That should give you a working custom mob, thats for taking the time to view this tutorial.

EnumToolMaterial + EnumArmourMaterial

Spoiler

Alot of people have been asking me how to make new materials without editing base class files, so here we go.

In the mod file there will be this for tools:

public static final Item NameherePickaxe = new ItemPickaxe(2005, EnumToolMaterial.EMERALD).setItemName("NameherePickaxe");

And this for armour:

public static final Item NamehereHelmet = new ItemArmor(1000, EnumArmorMaterial.DIAMOND, ModLoader.AddArmor("NamehereArmour"), 0).setItemName("NamehereHelmet");

or something to that effect.

All you have to do is create a new file that holds the materials and that, so make a new file called EnumNamehereToolMaterial for tools and EnumNamehereArmourMaterial for armour.
In EnumNamehereToolMaterial it would be:

package net.minecraft.src;

public enum EnumNamehereToolMaterial
{
    NAMEHERE1("NAMEHERE1", 0, 0, 59, 2.0F, 0, 15),
    NAMEHERE2("NAMEHERE2", 1, 1, 131, 4F, 1, 5);

    private final int harvestLevel;
    private final int maxUses;
    private final float efficiencyOnProperMaterial;
    private final int damageVsEntity;
    private final int enchantability;

    private EnumNamehereToolMaterial(String s, int i, int j, int k, float f, int l, int i1)
    {
        harvestLevel = j;
        maxUses = k;
        efficiencyOnProperMaterial = f;
        damageVsEntity = l;
        enchantability = i1;
    }

    public int getMaxUses()
    {
        return maxUses;
    }

    public float getEfficiencyOnProperMaterial()
    {
        return efficiencyOnProperMaterial;
    }

    public int getDamageVsEntity()
    {
        return damageVsEntity;
    }

    public int getHarvestLevel()
    {
        return harvestLevel;
    }

    public int getEnchantability()
    {
        return enchantability;
    }
}

Where it says:

NAMEHERE1("NAMEHERE1", 0, 0, 59, 2.0F, 0, 15),

The first number is the id it needs to look something along the lines of this:

NAMEHERE1("NAMEHERE1", 0, 0, 59, 2.0F, 0, 15),
NAMEHERE2("NAMEHERE2", 1, 1, 59, 2.0F, 0, 15),
NAMEHERE3("NAMEHERE3", 2, 2, 59, 2.0F, 0, 15);

ect.
The second number is the harvest level.
The third number is the number of uses.
The fourth number is efficiency against proper materials.
The fifth number is the damage.
The last number is the enchant-ability.

EnumNamehereArmourMaterial would be:

package net.minecraft.src;

public enum EnumNamehereArmorMaterial
{
    NAMEHERE1("NAMEHERE1", 0, 5, new int[] { 1, 3, 2, 1 }, 15),
    NAMEHERE2("NAMEHERE2", 1, 15, new int[] { 2, 5, 4, 1 }, 12);

    private int maxDamageFactor;
    private int damageReductionAmountArray[];
    private int enchantability;

    private EnumNamehereArmorMaterial(String s, int i, int j, int ai[], int k)
    {
        maxDamageFactor = j;
        damageReductionAmountArray = ai;
        enchantability = k;
    }

    public int func_40576_a(int i)
    {
        return ItemArmor.getMaxDamageArray()[i] * maxDamageFactor;
    }

    public int getDamageReductionAmount(int i)
    {
        return damageReductionAmountArray[i];
    }

    public int getEnchantability()
    {
        return enchantability;
    }
}

But alas i dont know what the numbers mean, so sorry, but iv'e tried searching it but i couldn't find out.

When you have made them work you want to go back to your mod_Namehere file and find these again:

public static final Item NameherePickaxe = new ItemPickaxe(2005, EnumToolMaterial.EMERALD).setItemName("NameherePickaxe");

public static final Item NamehereHelmet = new ItemArmor(1000, EnumArmorMaterial.DIAMOND, ModLoader.AddArmor("NamehereArmour"), 0).setItemName("NamehereHelmet");

And change them to:

public static final Item NameherePickaxe = new ItemPickaxe(2005, EnumNamehereToolMaterial.NAMEHERE1).setItemName("NameherePickaxe");

And

public static final Item NamehereHelmet = new ItemArmor(1000, EnumNamehereArmorMaterial.NAMEHERE2, ModLoader.AddArmor("NamehereArmour"), 0).setItemName("NamehereHelmet");

But change the namehere's to what you set it as. Sorry if its unclear

Advanced Block - by AussieTerra

Spoiler

Booster Block
all you need to do is make the block more slippery for it to increase your speed exponentially as you walk along the block.

add this to the blocknamehere.java

slipperiness = 1.0F;

so that it fits in like this

 public BlockNamehere(int i, int j)
    {
        super(i, j, Material.ground);
                slipperiness = 1.0F;
    }

(the higher the slipperiness the higher the speed multiplication)


Bouncy Block

to make your block boost you up in the air simply add this code to the blocknamehere

public void onEntityWalking(World world, int x, int y, int z,

Entity entity)
    {
            entity.motionY += 5.0;
    }

so that it fits like this

public int idDropped(int i, Random random)
    {
       return mod_Namehere.Namehere.blockID;
    }
        public void onEntityWalking(World world, int x, int y, int z, Entity entity)
    {
            entity.motionY += 5.0;
    }
    public int quantityDropped(Random random)
    {
            return 1;
    }
}

the normal jump height i believe is 1.0
(the same thing can be used for speed and side boosting (using int x or z respectively, possibly even diagonal with motionX += 5.0, motionZ += 5.0 )



Damage on contact

add this code to your blocknamehere after the line "return 1"

 public AxisAlignedBB getCollisionBoundingBoxFromPool(World world, int i, int j, int k)
    {
        float f = 0.0625F;
        return AxisAlignedBB.getBoundingBoxFromPool((float)i + f, j, (float)k + f, (float)(i + 1) - f, (float)(j + 1) - f, (float)(k + 1) - f);
    }
    public AxisAlignedBB getSelectedBoundingBoxFromPool(World world, int i, int j, int k)
    {
        float f = 0.0625F;
        return AxisAlignedBB.getBoundingBoxFromPool((float)i + f, j, (float)k + f, (float)(i + 1) - f, j + 1, (float)(k + 1) - f);
    }
        public void onEntityCollidedWithBlock(World world, int i, int j, int k, Entity entity)
    {
        entity.attackEntityFrom(null, 4);
    }

the 4 in the line

entity.attackEntityFrom(null, 4);

is the amount of damage per hit it deals. 1 is half a heart



Heal on contact

add this to the end of your blocknamehere (after the "return 1;"

public AxisAlignedBB getCollisionBoundingBoxFromPool(World world, int i, int j, int k)
{
    float f = 0.0625F;
    return AxisAlignedBB.getBoundingBoxFromPool((float)i + f, j, (float)k + f, (float)(i + 1) - f, (float)(j + 1) - f, (float)(k + 1) - f);
}

public AxisAlignedBB getSelectedBoundingBoxFromPool(World world, int i, int j, int k)
{
    float f = 0.0625F;
    return AxisAlignedBB.getBoundingBoxFromPool((float)i + f, j, (float)k + f, (float)(i + 1) - f, j + 1, (float)(k + 1) - f);
}
        
public void onEntityCollidedWithBlock(World world, int i, int j, int k, Entity entity)
{
    if(ModLoader.getMinecraftInstance().thePlayer.health < 20)
    {
        ModLoader.getMinecraftInstance().thePlayer.heal(4);
    }
}

the lines

if(ModLoader.getMinecraftInstance().thePlayer.health < 20)
    {
        ModLoader.getMinecraftInstance().thePlayer.heal(4);
    }

are basically saying if the players current health is less than 20 (full health) then heal the player 2 hearts per tick (extremely fast)

true i guess :/ i just want to help your mod

[XTremity]

Sorry but im a solo modder, i model, texture and make the things myself, its pretty fun but can get annoying, sorry.

[Bozkat]

how can i help your mod - like use the sig ( i already am though) but that kind of thing

[Creepermadness]

This is great! I made my first ''mod'' (only with dough block and dough ball, but hey, it's a start!). But the only problem is: I can't ''code'' the dough ball into a dough block, it says the item don't exist. But i safed the changes and can craft the dough ball already. Do you know what to do? Please reply

Btw: Great tutorials!!!
