ModLoader 1.3.2/1.3.1

Hello, my name is jbond98, I am a YouTuber and Minecraft Modder, and welcome to mymodding tutorials! You can check out myYouTube Channel, and my most popular mod,The

Wolfestone Modif you would like.

I'm going to start off fresh, and perfect for beginners, but eventually I'll have some advancedtutorials here too! My goal is to share my modding knowledge with other minecraft modders,and to eliminate some of the problems that Minecraft 1.3.1+ is causing modders. I will also tryto explain everything in as much detail as possible, so not only will you be able to see whatto do, you'll also learn what to do!

Setting Up MCP 7.2 with ModLoader 1.3.2 and Eclipse Juno 4.2

IntroductionIn order to ensure maximum efficiency and comfortably whilst modding, it is highly recommended to

use a java IDE, such as NetBeans or Eclipse with your Minecraft MCP. An IDE is an IntegratedDevelopment Environment which makes creating classes, testing features in your mod, and bugfixing a lot more convenient. Eclipse and NetBeans also have error highlighting and error quickfixfeatures which make fixing problems much easier. Although I personally recommend Eclipse, Ihaven't really had much experience with NetBeans.

Notepad++You may use Notepad++ if you don't want to use an IDE for minecraft modding. Notepad++ is afreeware source code editor that supports many different programming languages, most importantly

java. It does not have a built-in way to test your game, so you will have to use startclient.bat in yourMCP folder to test your mod in-game.

MCP 1.3.2 and Eclipse Juno 4.2 and ModLoaderIn order to correctly use Eclipse on your computer, you have to first set up your PATH variable. First,download the Java JDK link on the far left "Java Platform (JDK) 7u7", and then follow the instructionsbelow:

The following is an example of a PATH environment variable:

C:\Java\jdk1.7.0\bin;C:\Windows\System32\;C:\Windows\;C:\Windows\System32\Wbem

It is useful to set the PATH environment variable permanently so it will persist after rebooting. Tomake a permanent change to the PATH variable, use the System icon in the Control Panel. The

exact procedure varies depending on the version of Windows:

Windows XP:

1. Select Start, select Control Panel. double click System, and select the Advanced tab.

2. Click Environment Variables. In the section System Variables, find the PATH environmentvariable and select it. Click Edit. If the PATH environment variable does not exist, click New.

3. In the Edit System Variable (or New System Variable) window, specify the value of the PATHenvironment variable. Click OK. Close all remaining windows by clicking OK.

Windows Vista:

1. From the desktop, right click the My Computer icon.

2. Choose Properties from the context menu.

3. Click the Advanced tab (Advanced system settings link in Vista).



Windows 7:

1. From the desktop, right click the Computer icon.

2. Choose Properties from the context menu.

3. Click the Advanced system settings link.

Alright, now the hard part is over. You've set your PATH variable! Now to set up MCP 1.3.2 withEclipse Juno 4.2:

Download MCP 1.3.2 (MCP 7.2 for Minecraft 1.3.2)

Now you'll need to decompile your minecraft sources. Go tohttp://www.minecraft.netand log-

in to your account. You'll need to download a fresh minecraft_server.jar for 1.3.2. Now go toyour minecraft client. You'll need to force and update. After getting a fresh minecraft client, goto the ModLoader Download Page and download the most recent version of ModLoader.(Note: If there is no ModLoader 1.3.2, in this case wait for modloader to update or this will allcrash!) Install ModLoader as you would a regular mod. Now go to your .minecraft folder andcopy your bin and resources folders.

Now, put all three of these things (minecraft_server.jar, bin, resources) inside of your jarsfolder inside of your MCP 1.3.2 folder.

Now click the decompile.bat in your MCP folder. Wait until the decompiling process is finished.This might take a while!

Now run your eclipse.exe, it is inside of the eclipse folder (You get this at the end of installingeclipse). Set the eclipse workspace to your MCP folder/eclipse.

That's it! You're now ready to make that dream mod that you've always wanted! Go to theclient -> src -> net.minecraft.src package and make your mod_*** file in that package.

ModLoader Basic Template

Any mod_*** file:package net.minecraft.src;

import java.util.Random;

public class mod_*** extends BaseMod{

public void load(){

}

public String getVersion(){

return "1.3.2";}

}This is a simple ModLoader mod_*** file template. This is how you will start off all of yourmod_*** files.

What's in the code:package net.minecraft.srcThis tells minecraft what package your class is located in.Thisline is very important and should be at the top of every class that you ever create.

import java.util.Random;This line is very important if you want to generate ores in the game, or anything like that.

This imports java's Random function/methods library. You will see many other types ofimports in the game such as import java.util.Map, importa java.util.List and so on. Justremember to do this or you will get many errors in the long run.

public class mod_*** extends BaseModAll this line does is define this class as a publicclass, which means it can be referenced from anywhere, even outside of the package.Protected would mean that it can be referenced only inside of the package, and privatewould mean that it can be referenced only inside of the class. You would change mod_***to mod_NameOfYourMod. The extends BaseMod allows you to use methods outside ofthe mod_*** class, in this case, the main ModLoader methods located in BaseMod.java.

public void load(){

}This is ModLoader's main constructor. All ModLoader functions will go inside of the twocurly braces. That means anything starting with "ModLoader.", anything else will gooutside of this method. That means mehtods starting with "public static void" and thelikes.

return "1.3.2";}

This function returns the version of your mod. You can simply put "1.3.2" here orsomething like "MyMod V2.0 Minecraft 1.3.1" It doesn't really matter. This is what is going

to show up in the console when ModLoader loads your mod.

Modding Tutorials

All tutorials are 1.3.2 ModLoader Compatible! They will also work for 1.3.1.

Tutorial 1 - How to Make a New Block- 1.3.2 Ready

mod_*** File

package net.minecraft.src;import java.util.ArrayList;import java.util.Arrays;import java.util.List;import java.util.Map;import java.util.Random;public class mod_wolfestone extends BaseMod{public static final Block oreWolfestone = new BlockWolfestoneOre(160,0).setStepSound(Block.soundStoneFootstep).setBlockName("oreWolfestone").setHardness(4.5F).setResistance(5F).setLightValue(0.375F);

What's in the code:

import java.util.ArrayList;import java.util.Arrays;import java.util.List;import java.util.Map;import java.util.Random;These are probably all of the imports that you will possibly need in your mod_*** file. Adding an


6/41

import that you don't need won't hurt you, but forgetting to add one that you do need will cause someserious problems. In my various tutorials I will be showing what imports are needed for the specifictutorial, and for this one you don't need any of them. It is still good practice to put those at the topthough. To name a few of them, java.util,Arrays; is a java library that includes Array functions,

java.util.Map is for adding renderers to the map, but you don't need to worry about that right now.

public static final Block oreWolfestone = new BlockWolfestoneOre(160,0).setStepSound(Block.soundStoneFootstep).setBlockName("oreWolfestone").setHardness(4.5F).setResistance(5F).setLightValue(0.375F);This is the function that tells ModLoader to add your blocks to Minecraft. I will go over each part ingreater detail below:

public static final Block oreWolfestone = new BlockWolfestoneOrepublic static final Block is the actual function, and oreWolfestone is whatever you want thecoding name for your block to be. This is not the name that will show up for the ore in-game. Thatcomes later.

new BlockWolfestoneOreThis is the class that all of your block data is located it. You would change BlockWolfestoneOre tothe class where you block data is stored. Usually block classes start of with Block*** but this is justan organizational preference. More information about the Block*** file is further down the tutorial.

(160, 0)The number on the left, "160" is the block ID that you want your block to be registered to. To staysafe, start at 160, but make sure to pick numbers above 138(The last minecraft block ID that is inuse by real minecraft blocks) and lower than 256(This is where item IDs start. I will explain this later.)The 0 used to tell minecraft where your item texture appears on the terrain.png. In this tutorial we willbe setting the number to 0 because we will be overriding the terrain.png using ModLoader's overridefunction, and making our own texture.

.setStepSound(Block.soundStoneFootstep)This tells ModLoader what sound to tie to your block. It is crucial to put Block in front ofthe .soundStoneFootstep because it is not referenced in your class. You can put many othersounds here, .soundGrassFootstep and .soundMetalFootstep, to name a few. Look in the Block.javaclass for the full list of sounds.

.setBlockName("oreWolfestone")This is only the coding name used for your block, not the name that will appear in-game. Use the

same name you put at the beginning of the function.

.setHardness(4.5F)This sets your block's hardness. Since the number is a float, you will need to put "F" after thenumber. This number can be positive or negative. If you put a negative number here, that will makeyour block unbreakable in Survival Mode, like bedrock. (In java, a float is any number with a decimalpoint. An integer on the other hand, or an int has no decimal points and is a positive or negativenumber.)


7/41

.setResistance(5F)This sets your block's resistance to TNT or any other explosives. Normal blocks have any wherefrom 1 to about 5 resistance. Obsidian has a resistance of 2000, which makes it immune toexplosive damage.

.setLightValue(0.375F)This sets your block's light value. Since it is a float it can be a decimal number. Light values inminecraft range from 0F to 1F. 0 Meaning no light, 1 meaning full light. Light values cannot benegative numbers, and if you go over 1, nothing will happen because minecraft will not recognizeanything over 1F. Note: If you decide to set your light value to 0, you do not needthis .setLightValue function, and you can remove it. Same goesfor.setResistance and .setHardness

oreWolfestone.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/textures/WolfestoneOre.png");This will set your block's texture in minecraft, and override the terrain.png, meaning that you will not

have to put your textures in that file. You will now need 16x16 pixel textures for each block in yourmod. When you have those textures put them inside a folder, I named mine textures. You don't haveto but it helps organize your textures, so they are not cluttered in the main bin folder.The/texture/WolfestoneOre.png is where you have placed your texture inside of the minecraft.jarfile. Mine is inside of a textures folder.

ModLoader.registerBlock(oreWolfestone);This code registers your block. If you do not do this, your game will crash! Also, make sure that it isinside of your public void load method. All you have to do here is change oreWolfestone to thecoding name of your new block.

ModLoader.addName(oreWolfestone, "Wolfestone Ore");This is where you will set the in-game name of your block. Change oreWolfestone to the codingname of your block, and change "Wolfestone Ore" to what you want the in-game name of yourblock to be. Make sure it is in quotations! Or else java will not read this as a string, and give youproblems

public String getVersion(){return "Wolfestone Mod V2.0 Minecraft 1.3.2";}This is the version of your mod. You can pretty much put anything here, as long as it is in quotations.

I put the version of my mod along with what Minecraft version that it runs in. This is what will showup in the console when ModLoader loads your mod.

Block*** File

package net.minecraft.src;import java.util.Random;public class BlockWolfestoneOre extends Block


8/41

{public BlockWolfestoneOre(int par1, int par2){

super(par1, par2, Material.rock);this.setCreativeTab(CreativeTabs.tabBlock);

}

public int quantityDropped(int par1){

return (1);}

public int idDropped(int par1, Random par2Random, int par3){

return mod_wolfestone.wolfestone.shiftedIndex;}}

What's in the code:I won't go into too much detail about this class, but here is what you need to know:

public class BlockWolfestoneOre extends BlockThis is your main method. It names the class, and tells minecraft that it extends the Block.java class,which means that you'll be able to use many functions from Block.java in your own Block*** class.

public BlockWolfestoneOre(int par1, int par2)This is your class constructor, and it is telling your mod_*** that it takes two parameters, int par1 andint par2. par1 and par2 are two different integer variables.

super(par1, par2, Material.rock);This is the super constructor, all you need to do here is change Material.rock to whatever materialyou want. Material.glass and Material.wood, to name a few. Each different material has differentproperties, and they are all listed in the Materials.java class.

this.setCreativeTab(CreativeTabs.tabBlock);This sets your block to the "Blocks" tab in Creative mode. You can also use .tabMaterials or.tabTools instead of.tabBlock, to name a few. The full list of Creative tabs is in theCreativeTabs.java class.


return (1);}This is telling minecraft to drop one of 'whatever it drops' ('whatever it drops' is set in the nextfunction). You can change this to whatever you want, as long as it is an integer. You can also setthis to a random number, but I won't really get into that. If you really want to know, ask me of look inthe code for lapis lazuli.


9/41


return mod_wolfestone.wolfestone.shiftedIndex;}

This is what the block will drop once you break it. Here it is a wolfestone gem, but you can literallyput anything. If it is an item, make sure to put Item. in front of it. If it is in your mod_*** class, putmod_***. in front of it, and same goes for blocks, put Block. in front of it. The .shiftedIndex onlyworks for items, so if you want it to drop a block, make sure to put .blockID after your item.

If you do not want to create a separate Block*** file:If your block doesn't really do anything too special, you don't have to make a separate Block*** classfor it! In your mod_*** class, just change the following:

public static final Block oreWolfestone = new BlockWolfestoneOre(160,0).setStepSound(Block.soundStoneFootstep).setBlockName("oreWolfestone").setHardness(4.5F).setResistance(5F).setLightValue(0.375F);

public static final Block oreWolfestone = new Block(160,0).setStepSound(Block.soundStoneFootstep).setBlockName("oreWolfestone").setHardness(4.5F).setResistance(5F).setLightValue(0.375F);

All this does is change the class extension for oreWolfestone to Block, instead ofBlockWolfestoneOre. This is useful for simple blocks that don't really need much customization.

You can not add your block to the creative inventory if it doesn't have a separate class!

Tutorial 2 - How to Make a New Item-1.3.2 Readymod_***

package net.minecraft.src;import java.util.Random;

public class mod_YourMod extends BaseMod{public static final Item yourItem = new ItemYourItem(5000).setItemName("yourItem");public void load(){yourItem.iconIndex = ModLoader.addOverride("/gui/items.png", "/textures/yourItem.png");

ModLoader.addName(yourItem, "Your Item");

yourItem.setTabToDisplayOn(CreativeTabs.tabMaterials);}

public String getVersion()

{return "1.3.2";}}

What's in the code:

public static final Item yourItem = new ItemYourItem(5000).setItemName("yourItem");This method adds your item to Minecraft. new ItemYourItem(5000) is the item ID, and ItemYourItemis the class that your item will extend, you can put "Item" here instead if your items doesn't have anyspecial characteristics. I chose 5000 for the ID just to be safe. .setItemName("yourItem") sets thecoding name for your item. This should be the same as the name here: public static final ItemyourItem.

wolfestone.iconIndex = ModLoader.addOverride("/gui/items.png", "/textures/Wolfestone.png");This overrides the regular items.png with your custom texture. I put my textures in a folder namedtextures. This folder would go inside of your minecraft.jar

ModLoader.addName(yourItem, "Your Item");This sets the in-game name for your item.

yourItem.setTabToDisplayOn(CreativeTabs.tabMaterials);This will set your new item to the Creative inventory tab "Materials." Use this only if you don't have aseparate class that extends your item. Look at my Creative Inventory tutorial for more information.

Tutorial 3 - How to Add Items/Blocks to the Creative Inventory- 1.3.2 ReadyBlock***/Item*** File

package net.minecraft.src;import java.util.Random;

public class BlockWolfestoneOre extends Block{public BlockWolfestoneOre(int par1, int par2){

super(par1, par2, Material.rock);this.setCreativeTab(CreativeTabs.tabBlock);

}


return (1);}


return mod_wolfestone.wolfestone.shiftedIndex;}}Now, in 1.3.2, adding items to the Creative Inventory is very easy! All you have to do is add one linein your Block***/Item*** file! This will work for both.

this.setCreativeTab(CreativeTabs.tabBlock);All you need to do is add this line in your main Block***/Item*** constructor function. Right below thesuper constructor. What this line of code will do is add your block to the Blocks tab. You canchange CreativeTabs.tabBlock to any tab you want, such as .tabMaterials or .tabTools. The full listis in the CreativeTabs.java class.

If you do not have separate classes for Items:If you do not have separate classes for your Items you can still add them to the Creative Inventoryby putting this line of code inside of the public void load method inside of your mod_*** class:

YourItem.setTabToDisplayOn(CreativeTabs.tabMaterials);In this case you would changeYourItem to the item that you would like to add to the Creativeinventory.

Tutorial 4 -Adding Textures to your Items and Blocks- 1.3.2 ReadyAdding Custom Textures to Items:

yourItem.iconIndex = ModLoader.addOverride("/gui/items.png", "/textures/YourItem.png");This ModLoader method overrides the in-game items.png, so that you can use your own textures

without worrying about compatibility problems with other mods. Replace yourItem with the codingname of your item. Now, all you have to do is tell ModLoader where the texture is. putting"/YourItem.png" as the second parameter to the .addOverride function will tell ModLoader that youritem is on the root directory of the minecraft.jar, but if you put it in a folder, such as textures, it will bemore organized, which is what I did here.

Adding Custom Textures to Blocks:

yourBlock.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/textures/YourBlock.png");Adding custom textures to blocks is almost identical to adding textures to items, just instead of.iconIndex, it is .blockIndexInTexture. Same rules apply for the rest of the function.

Remember that both the item and block texture override methods go INSIDE of the public

void load method!

Tutorial 5 -Adding New Crafting Recipes (Including Dyes!)- 1.3.2 Ready

Adding new recipes is easy with ModLoader. Just add the following code from this tutorial to yourmod_*** file in the public void load() method.

ModLoader.addRecipe(new ItemStack(blockWolfestone, 1), new Object [] {"###", "###", "###",

Character.valueOf('#'), mod_wolfestone.wolfestone});Adding new crafting recipes with ModLoader is easy! I'll be using some recipes from The WolfestoneMod in this tutorial. Imagine the the "###", "###, "###", as the minecraft crafting grid.

"###","###","###",Like this. This is how you will input your new crafting recipes. Top row is first, then second row, andlast row.

Character.valueOf('#'), mod_wolfestone.wolfestone

This function tells ModLoader what the # is supposed to be in the recipe. You can use almost anycharacter for this, but try to keep it down to simple symbols and letters.

The crafting recipe listed above is one for a Wolfestone Block, but that is pretty easy. Let's try acrafting recipe that is a little bit harder.

ModLoader.addRecipe(new ItemStack(wolfestoneBow, 1), new Object [] {" #X", "M X", " #X",Character.valueOf('#'), Item.stick, Character.valueOf('X'), Item.silk, Character.valueOf('M'),mod_wolfestone.wolfestoneShard});Here is a recipe that is a bit more complicated. Look at how there are now three different symbols inthe crafting grid. You have to tell ModLoader what each of them are, so you have to make anew Character.valueOf() function for each new symbol.

ModLoader.addRecipe(new ItemStack(wolfestoneShard, 4), new Object [] {"#",Character.valueOf('#'), mod_wolfestone.wolfestone});Some recipes are shapeless, meaning that you can put them anywhere on the grid and they will stillwork. So for this recipe as long as there is one piece of wolfestone in the crafting grid, whether it isthe 2x2 or 3x3, it will still produce four wolfestone shards.

ModLoader.addShapelessRecipe(new ItemStack(wolfestoneShard, 4), new Object[]{ wolfestone });This is another way to add a shapeless recipe. As long as there is a piece of wolfestone in thecrafting grid, it will give me 4 wolfestone shards.

ModLoader.addRecipe(new ItemStack(torchWolfestone, 8), new Object [] {"#", "X",Character.valueOf('#'), mod_wolfestone.wolfestoneShard, Character.valueOf('X'), Item.stick});Same goes with torches.

Look at the CraftingManager.java to get a better idea of crafting recipes, and what they look like forevery craftable item in the game. Now you know how to make your very own crafting recipes!

Tutorial 6 -Adding A New Food- 1.3.2 Readymod_***

package net.minecraft.src;public class mod_YourModName extends BaseMod{public static final Item nameHere = new ItemFood(5000, 6, 1F, true).setItemName("anyNameHere");

public void load(){foodNameHere.iconIndex = ModLoader.addOverride("/gui/items.png", "/image.png");

ModLoader.addName(foodNameHere, "My Food");}public String getVersion(){

return "1.3.1 MyModDescription";}}There are no new lines of code here. The only part that you would need to change is where youinitialize your item. And no, you can not make blocks edible! In the case of my own mod, I made it sothat you can craft an edible item out of the block. If anyone needs further explanation, I can add it tothis tutorial.

What's in the code:

public static final Item nameHere = new ItemFood(5000, 6, 1F, true).setItemName("anyNameHere");The only thing that is new here is the ItemFood(5000, 6, 1F, true). You MUST make your itemextend the class ItemFood! The 5000 is your item ID, the 6 stands for how many half food icons thatyour food can heal, not hearts! These are the icons that resemble a corndog right next to yourregular hearts. This item will heal 3 full 'food icons.' The 1F stands for how long you can go beforeyou get hungry again, the food saturation level. Lastly, true is a boolean that tells minecraft if yourfood can be fed to wolves. I put true here just for kicks.

Tutorial 7 -Adding New Smelting Recipes- 1.3.2 ReadyAdding New Smelting Recipes For Items:

ModLoader.addSmelting(yourItem.shiftedIndex, new ItemStack(yourSmeltedItem, 1), 1.0F);If you want to add new smelting recipes to your mod you will need to add this line of code above,

into your public void load() method in your mod_*** class. It takes three parameters:

1. yourItem.shiftedIndex, this parameter has to be an integer, so we would use .shiftedIndex tofind the item ID of our item. Put the name of your item you want to input into your furnacewhere it says yourItem.

2. new ItemStack(yourSmeltedItem, 1), this parameter takes a new instance of the classItemStack, which takes two more parameters: yourSmeltedItem which is what the furnacewill output once the input is smelted, and 1, this number is the amount you will get of theoutput once it is smelted.

3. 1.0F, the last parameter is a float, which means that it can be a decimal number. This is howmuch XP you will receive after each successful smelt.

Adding New Smelting Recipes For Blocks:

ModLoader.addSmelting(yourBlock.blockID, new ItemStack(yourSmeltedBlock, 1), 1.0F);Adding smelting recipes for blocks is almost identical to adding smelting recipes for items. The onlything that changes is the first parameter:

1. yourBlock.blockID, this parameter has to be an integer, so we would use .blockID to find theblock ID of our block. This is the only difference between items and blocks. Put the name ofyour item you want to input into your furnace where it says yourBlock.

2. new ItemStack(yourSmeltedBlock, 1), this parameter takes a new instance of the classItemStack, which takes two more parameters: yourSmeltedBlock which is what the furnacewill output once the input is smelted, and 1, this number is the amount you will get of theoutput once it is smelted. Even though this references the class ItemStack, this still works forBlocks!

3. 1.0F, the last parameter is a float, which means that it can be a decimal number. This is howmuch XP you will receive after each successful smelt.

Tutorial 8 -Adding New Fuels- 1.3.2 Ready

public int addFuel(int par1, int par2){if(par1 == yourFuelItem.shiftedIndex)

{return 9600;}if(par1 == yourFuelBlock.blockID){return 14400;}

return 0;}In order to add new fuels to your mod you need to put this function in your mod_*** file. Make surethat it is NOT inside of the public void load() method! A fuel is and item or block that will power afurnace, such as coal or a block of wood, for example.

If you want to add a new fuel that is an item:

if(par1 == yourFuelItem.shiftedIndex){return 9600;}If you want to add a new fuel that is an item, use this if-statement inside of the public int addFuel()function. yourFuelItem.shiftedIndex is the item that you want to be a fuel. Since this requires aninteger, and we are dealing with items, we will be using .shiftedIndex. return 9600 returns theamount of ticks the furnace fuel will last. The number of ticks required to smelt one item is 200. Coalsmelts for 1600 ticks. This particular item will smelt 48 blocks.

If you want to add a new fuel that is an item:

if(par1 == yourFuelBlock.blockID){return 14400;}If you want to add a new fuel that is a block, use this if-statement inside of the public int addFuel()function. yourFuelBlock.blockID is the block that you want to be a fuel. Since this requires aninteger, and we are dealing with blocks, we will be using .blockID. return 14400 returns the amountof ticks the furnace fuel will last.

Tutorial 9 - How To Generate Your Own Ore In The Overworld- 1.3.2 Ready

public void generateSurface(World world, Random random, int i, int j){for(int k = 0; k < 5; k++)

{int randPosX = i + random.nextInt(16);int randPosY = random.nextInt(128);int randPosZ = j + random.nextInt(16);(new WorldGenMinable(yourOreBlockName.blockID, 17)).generate(world, random, randPosX,

randPosY, randPosZ);}}In order to generate your own ore on the surface (overworld) you will need to use thiscode outside of the public void load() method.

public void generateSurface(World world, Random random, int i, int j)

This is the ModLoader function that allows modders to generate ores in the overworld.

for(int k = 0; k < 5; k++)This is the initialization for your 'for-loop' The only thing that you need to change here is the k < 5, toany number that you want. This number changes the amount of times that your ore vein cangenerate per chunk. In laymen's terms, this number controls the rarity of your ore.

int randPosX = i + random.nextInt(16);int randPosY = random.nextInt(128);int randPosZ = j + random.nextInt(16);

This code is used to find a random x, y, and z variable to spawn the ore vein. Since the y and zcoordinates are "flipped" in minecraft (usually the height would be a z coordinate, but here y is theheight coordinate) you will have to use the y coordinate as your height coordinate.

Basically, this code will find random coordinates in a chunk (16 X 16 X 128) to spawn your ore in. Ifyou want your ore to be found only in underground areas, consider changing int randPosY =random.nextInt(128); to something more like int randPosY = random.nextInt(48); Diamond is foundat int randPosY = random.nextInt(16); for reference.

(new WorldGenMinable(yourOreBlockName.blockID, 17)).generate(world, random, randPosX,randPosY, randPosZ);This code uses the information above (the random x, y, and coordinate) as well as the

WorldGenMineable class to find the most suitable place to generate your ore. The only thing thatyou would need to change here is this: (yourOreBlockName.blockID, 17), you would put the nameof your block, with .blockID here. The 17 is the maximum amount of ore that can spawn in each vein.Diamond is 7, for reference.

Tutorial 10 - How To Generate Your Own Ore In The Nether- 1.3.2 ReadyGenerating an ore in the nether is simple, and almost identical to generating an ore in the overworld!The only difference are some parts in the function.

public void generateNether(World world, Random rand, int i, int j){

for(int m = 0; m < 7; m++){

int randPosX = i + rand.nextInt(16);int randPosY = rand.nextInt(128);int randPosZ = j + rand.nextInt(16);(new NetherGenMinable(yourNetherOre.blockID, 15)).generate(world, rand, randPosX,

randPosY, randPosZ);}

}I won't go into too much detail on this function. Look at the previous tutorial if you want a fullexplanation. What you have to do here is change int randPosY = rand.nextInt(128); to the

maximum height you want your ore to generate in the nether.

(new NetherGenMinable(yourNetherOre.blockID, 15)), this is the key to properly generating yourore in the nether. Change the 15 to what you want the max vein size to be.Also, you must create anew class. Call if whatever you want, but I called mine NetherGenMinable.

NetherGenMinable

package net.minecraft.src;import java.util.Random;public class NetherGenMinable extends WorldGenerator{/** The block ID of the ore to be placed using this generator. */private int minableBlockId;/** The number of blocks to generate. */private int numberOfBlocks;public NetherGenMinable(int par1, int par2){

Tutorial 11 - How To Create/Add Your Own Custom Achievements- 1.3.2Creating and adding your own achievements to the Achievement map is pretty easy! In order toinitiate your achievement use the following code:

public static final Achievement achievementName = new Achievement(5000, "achievementName",4, 9, Item.diamond, null).registerAchievement();This initializes your new achievement. Make sure to place this code outside of your public voidload() method!

Change achievementName to the coding name of your achievement. Now, i'll explain (5000,"achievementName", 4, 9, Item.diamond, null) in greater detail:

5000 is your achievement ID. Try to go over 5,000 just to be safe. "achievementName" this is again, just the coding name of your achievement. Make sure that

is the same as the achievementName before it. 4, 9, is the position of your achievement on the achievement grid. You'll pretty much have to

just guess and check this one. Item.diamond this is what the achievement image will look like when you get it. You can

change this to anything you want. null keep this as is for now, I'll explain what this does further in the tutorial.

Now, inside of your public void load() method, you need to put this line of code:

ModLoader.addAchievementDesc(achievementName, "Achievement Name", "AchievementDescription");

This is a ModLoader function for adding a new achievement name and description to yourachievement:

Where it says achievementName you must put the coding name of your achievement. Change "Achievement Name" to what you want the actual in-game name of the

achievement to be when you get it. Lastly, change "Achievement Description" this is what will be underneath your achievement

name in the achievement grid; moreover, the achievement description. Try not to make thistoo long.

Finally, underneath your public void load() method, you want to add:

public void takenFromCrafting(EntityPlayer entityplayer, ItemStack itemstack, IInventory iinventory){if(itemstack.itemID == Block.blockDiamond.blockID){

entityplayer.addStat(achievementName, 1);}}What this does is trigger the achievement when something is crafted, more specifically a diamond


21/41

block. This is one of the many ways to trigger an achievement. Some of the others are a bit morecomplicated.

Change Block.blockDiamond.blockID to the block or item that you want to trigger theachievement once crafted.

Lastly, change achievementName to the coding name of your achievement.

Making An Achievement Require Another Achievement:This will make it so that you need to trigger another achievement first, before getting your ownachievement. I will be using the "Build Better Pickaxe" in-game achievement for this tutorial:

static Achievement buildBetterPickaxe = AchievementList.buildBetterPickaxe;This sets up a variable for the in-game achievement so that it can be used inside of your mod_class. You can change the buildBetterPickaxe in both cases to any achievement in the game, oreven some of your own custom achievements (if you have multiple custom achievements). Look in

AchievementList.java for the whole list of minecraft achievements.

public static final Achievement achievementName = new Achievement(5000, "achievementName",4, 9, Item.diamond, null).registerAchievement();Now we can go back and change our original achievement declaration. Rembember the 'null' partthat I was talking about? Well you can now change null to the name of the achievement that youwant yours to "offspring" off of, or, in this case make it so that in order to get your achievement,it requires the "Build Better Pickaxe" achievement first:

public static final Achievement achievementName = new Achievement(5000, "achievementName",4, 9, Item.diamond, buildBetterPickaxe).registerAchievement();

Making An Achievement Special:

This means that the achievement will have a spiky frame around it in the achievement GUI, or grid,as I call it. All that you have to do is add the following code to your achievement initiation:

.setSpecial()

The finished code will look like this in your initiation:public static final Achievement achievementName = new Achievement(5000, "achievementName",4, 9, Item.diamond, buildBetterPickaxe).setSpecial().registerAchievement();

Tutorial 14 - How To Add Custom Trees/Saplings- 1.3.2Making a new tree is a very complicated process. For this tutorial, I will be creating a new tree andsapling that will generate in the Forest. Later on I will show you how to make the tree generate inyour own biome and even in your own dimension. Note that this tutorial is only for generating yourtree in a pre-made minecraft biome in the overworld.

mod_***In order to get your tree to generate in a specific biome, you will need to put this code under thepublic void load() method in your mod_ file. If you already have a generateSurface() method, makesure to add the code inside of it to your already made method. Make sure that you h ave defined anew typ e of woo d, leaf, and sapl ing in you r mod_ class also. I go o ver how to in i t ia te blocks

and i tems in my earl ier tutor ia ls.

public void generateSurface(World world, Random rand, int chunkX, int chunkZ){BiomeGenBase biome = world.getWorldChunkManager().getBiomeGenAt(chunkX, chunkZ);

WorldGenYourTree tree = new WorldGenYourTree(); //Change this to the World Gens or your treeand make sure that the parameters match if you get errors!if(biome instanceof BiomeGenForest){for(int c = 0; c < 3; c++){int Xcoord = chunkX + rand.nextInt(16);int Zcoord = chunkZ + rand.nextInt(16);

int i = world.getHeightValue(Xcoord, Zcoord);tree.generate(world, rand, Xcoord, i, Zcoord);

}}}What this code will do is find a random X and Z location within a chunk and generate a tree there.This will generate 3 trees within any given chunk. Lowering the c < 3 will result in less trees, and viceversa.

In order to actually generate anything you will need a new WorldGenYourTree class.WorldGenYourTree

package net.minecraft.src;


public class WorldGenYourTree extends WorldGenerator

}}This class determines the shape of your tree, and what types of leaves it will use and what type ofwood it will use to generate your tree. It also determines what blocks your tree can spawn on. All thatyou need to do here is change some of the names around, and the rest is explained in thecomments.

In order to make your own type of wood log you will need the following classBlockYourLog



public class BlockYourLog extends Block{protected BlockYourLog(int i){

super(i, Material.wood);}

public int quantityDropped(Random random){

return 1;}

public int idDropped(int i, Random random, int j){

return mod_yourMod.yourLog.blockID; //Change to your wood block}

byte byte0 = 4;int l = byte0 + 1;if(world.checkChunksExist(i - l, j - l, k - l, i + l, j + l, k + l)){

for(int i1 = -byte0; i1

}return j != 2 ? 20 : 117;

}

protected int damageDropped(int i)

{return i;

}}The getBlockTextureFromSideAndMetadata() method is something new, and is something that I willgo over in my multi-textured blocks tutorial. That is coming up soon. Basically what this class does itget the texture of your wood block, and it also gets the ID of the item that your block drops, which isthe wood block itself.

Next you will need a new leaves class.BlockYourLeaf


import java.util.Random;public class BlockYourLeaf extends BlockLeavesBase{private int baseIndexInPNG;int adjacentTreeBlocks[];

protected BlockYourLeaf(int i, int j){

super(i, j, Material.leaves, false);setTickRandomly(true);

}

double d = 0.5D;double d1 = 1.0D;return 0;

for(int j1 = -l; j1


34/41

world.setBlockMetadata(i + j1, j + k1, k + l1, j2 | 8);}

}}

}}

}public void updateTick(World world, int i, int j, int k, Random random){

if(world.isRemote){

return;}int l = world.getBlockMetadata(i, j, k);if((l & 8) != 0 && (l & 4) == 0){

byte byte0 = 4;int i1 = byte0 + 1;byte byte1 = 32;

int j1 = byte1 * byte1;int k1 = byte1 / 2;if(adjacentTreeBlocks == null){

return !graphicsLevel;}public int getBlockTextureFromSideAndMetadata(int i, int j){

super.onEntityWalking(world, i, j, k, entity);

}}This creates all of the technical things for your new leaf block.

Lastly, you need a new sapling blockBlockYourSapling



public class BlockYourSapling extends BlockFlower{protected BlockYourSapling(int i, int j){

super(i, j);float f = 0.4F;setBlockBounds(0.5F - f, 0.0F, 0.5F - f, 0.5F + f, f * 2.0F, 0.5F + f);

}

protected boolean canThisPlantGrowOnThisBlockID(int i){

return i == Block.grass.blockID; //Makes this grow on grass.}

public void updateTick(World world, int i, int j, int k, Random random){

if(world.isRemote){

return;}super.updateTick(world, i, j, k, random);

if(world.getBlockLightValue(i, j + 1, k) >= 9 && random.nextInt(7) == 0){

int l = world.getBlockMetadata(i, j, k);if((l & 8) == 0){

world.setBlockMetadataWithNotify(i, j, k, l | 8);} else{

growTree(world, i, j, k, random);}

}}public int getBlockTextureFromSideAndMetadata(int i, int j){

j &= 3;if(j == 1){

return blockIndexInTexture; //63}

Tutorial 15 - How To Create A New Biome- 1.3.2Creating a new biome is an interesting, but not very complex process. I will show you the basics,and you can add on to this on your own to make the new biome yours. This tutorial will show how togenerate the biome in the overworld using your own top and filler block and also show you how togenerate your own tree from the previous tutorial inside of the biome. This tutorial will not show you

how to generate your biome in your new dimension, that is for the next tutorial.

mod_***First off, you will need the following lines of code inside of your mod_*** class.

public static final BiomeGenBase biomeName = (newBiomeGenYourBiome(40)).setBiomeName("Biome Name");Put this code outside of the public void load() method.

Change biomeName to the coding name of your biome. (new BiomeGenYourBiome(40) casts your BiomeGen class upon a new Biome ID. Make

sure that the number you put here is lower than 127 because of java's byte limit. .setBiomeName("biomeName") sets the in-game name of your biome. This is only visible

from the F3 (debug) menu when you're in that biome.

ModLoader.addBiome(nameHere);Put this code inside of the public void load() method. This is the ModLoader function for adding anew biome to the world generation list.

public static void generateSurface(World world, Random rand, int chunkX, int chunkZ){BiomeGenBase biome = world.getWorldChunkManager().getBiomeGenAt(chunkX, chunkZ);

WorldGenYourTree tree = new WorldGenYourTree();

if(biome instanceof BiomeGenYourBiome){

for(int x = 0; x < 8; x++){tree = new WorldGenYourTree();int Xcoord = chunkX + rand.nextInt(16);int Zcoord = chunkZ + rand.nextInt(16);int i = world.getHeightValue(Xcoord, Zcoord);tree.generate(world, rand, Xcoord, i, Zcoord);}

}

}Put this code outside of your public void load() method. If you already have a generateSurface()method with ore generation and such inside of it, then make sure to add the contents of this one to it.Make sure to change the names of the WorldGens to fit your trees. for(int x = 0; x < 8; x++) is therarity of your trees per chunk. Change the 8 to fit your needs.

Make sure that you also add two new blocks, a new type of grass and dirt, to your mod_*** filefollowing my new block tutorial. To make the new type of grass, make sure to use code fromBlockGrass.java and my multi-textured block tutorial.

BiomeGenYourBiome

package net.minecraft.src;import java.util.Random;public class BiomeGenWolfeland extends BiomeGenBase

{public BiomeGenWolfeland(int par1){

super(par1);this.spawnableCreatureList.clear();this.spawnableMonsterList.clear();this.spawnableWaterCreatureList.clear();this.topBlock = (byte)mod_wolfestone.wolfeGrass.blockID;this.fillerBlock = (byte)mod_wolfestone.wolfeDirt.blockID;this.minHeight = -0.4F;this.maxHeight = 0.54F;

}This class handles all of the little details included in a biome.

this.spawnableCreatureList.clear(); This clears any passive mobs from spawning in yourbiome.

this.spawnableMonsterList.clear(); This clears any monsters from spawning in your biomeat night.

this.spawnableWaterCreatureList.clear(); This clears squid from spawning in your biome. Ifyou want to know how to spawn a specific creature in the biome, have a look at the otherBiomeGen classes.

this.topBlock = (byte)mod_yourMod.yourGrass.blockID; Sets the top block for yourbiome. This is the first layer that you see, such as grass in most biomes. This will work for anyblock. You can even set this to lava, but it will get really messy...

this.fillerBlock = (byte)mod_yourMod.yourDirt.blockID; This sets the filler block for your

biome. The filler block is the block 4-5 layers deep after the top block. This is usually dirt inmost cases, but again, you can set this to anything you like. this.minHeight = -0.4F; This sets the minimum height for you biome. Setting this below 0F,

makes lakes able to generate in your biome. this.maxHeight = 0.54F; Sets the maximum height for you biome. If you want large

mountains, try setting larger numbers.

And that's it! You have now created your own custom biome. Please test this tutorial, and tell me if itworks in the comments below. If you are having a problem with this tutorial, please tell me and I willfix it. The Dimension tutorial should come out soon.

This should do i t for the creat ing your o wn b iome tutor ia l ! Ask any quest ions below, or tel l

Tutorial 16 - Crafting Recipes With Dyes!- 1.3.2[spoiler][CODE]ModLoader.addRecipe(new ItemStack(cobblestone, 1), new Object [] {" #", Character.valueOf('#'),new ItemStack(Item.dyePowder, 1, 12)});[/CODE]What this would do is make one piece of light blue dye give me one piece of cobblestone in

the crafting grid.

Look at crafting with dyes this way:[CODE]Character.valueOf('#'), new ItemStack(Item.dyePowder, amount, damageValue)});[/CODE]The amount is how much needs to be present, or the amount. You still have to keep thiseven if it is as a crafting ingredient. The damage value is what determines the color of the dye.Please refer to this chart for the damage or ID values of each dye:
