This is a tutorial about modding with ModLoader. If you want to mod without ModLoader you have to search for your own (i dont want to make ad for other tutorials)

So now i want to say that this tutorial is simply AWESOME! You really did/do a great job! I hope someday i will as good as you in modding/programming..

But now a few questions;
1. I made an unbreakable Block with a dirt texture but when i walk over it it sounds like stone.. Why you haven't add the "setStepSound" Method to the Block-Tutorial? Example:

.setStepSound(Block.soundGravelFootstep)

2. I also added unbreakable wood & planks to the creative inventory and i can see the different woodtextures in the inventory but when i choose one and place it, i place a wood block with standart wood texture...

declaration:

public static final Block unbreakPlanks = (new BlockWood(134)).setBlockName("unbreakPlanks")
.setBlockUnbreakable().setResistance(600000F).setStepSound(Block.soundWoodFootstep).disableStats().setRequiresSelfNotify();

public static final Block unbreakWood = (new BlockLog(135)).setBlockName("unbreakWood")
.setBlockUnbreakable().setResistance(600000F).setStepSound(Block.soundWoodFootstep).disableStats().setRequiresSelfNotify();

add to creative inventory:

for (int i2 = 0; i2 < 4; i2++) {list.add(new ItemStack(unbreakPlanks, 1, i2));}
//shows the difficult woodtextures in the inventory
for (int i2 = 0; i2 < 4; i2++) {list.add(new ItemStack(unbreakWood, 1, i2));}  
  //but if you set the block it has the default texture  ! >.<

How can you make ores generate in the nether? Do you just change 'generateSurface' to 'generateUnderWorld'? lol its a wild guess.

Block.stone.blockID

Block.netherrack.blockID

public void generateSurface(World world, Random random, int chunkX, int chunkZ)
		{
				for(int Example1 = 0; Example1 < 10; Example1++)
				{
						int Example1X = chunkX + random.nextInt(16);
						int Example1Y = random.nextInt(20);
						int Example1Z = chunkZ + random.nextInt(16);
						(new WorldGenMinable(Example1 .blockID, 4)).generate(world, random, Example1X, Example1Y, Example1Z);

				}
				for(int Example2 = 0; Example2 < 120; Example2++)
				{
						int Example2X = chunkX + random.nextInt(16);
						int Example2Y = random.nextInt(128);
						int Example2Z = chunkZ + random.nextInt(16);
						(new WorldGenMinable(Example2.blockID, 3)).generate(world, random, Example2X, Example2Y, Example2Z);
				}
		}

public void generateNether(World world, Random random, int chunkX, int chunkZ)
		{				
				for(int NetherExample = 0; NetherExample < 80; NetherExample++)
				{
						int NetherExampleX = chunkX + random.nextInt(16);
						int NetherExampleY = random.nextInt(128);
						int NetherExampleZ = chunkZ + random.nextInt(16);
						(new NetherGenMinable(NetherExample.blockID, 25)).generate(world, random, NetherExampleX, NetherExampleY, NetherExampleZ);
				}
		}

I'm still having the error. If anyone code help, please do.

public void generateSurface(World world, Random random, int chunkX, int chunkZ)
		{
				for(int OreOne = 0; OreOne < 10; OreOne++)
				{
						int OreOneX = chunkX + random.nextInt(16);
						int OreOneY = random.nextInt(20);
						int OreOneZ = chunkZ + random.nextInt(16);
						(new WorldGenMinable(OreOne.blockID, 4)).generate(world, random, OreOneX, OreOneY, OreOneZ);

				}
				for(int boneOre = 0; boneOre < 120; boneOre++)
				{
						int boneOreX = chunkX + random.nextInt(16);
						int boneOreY = random.nextInt(128);
						int boneOreZ = chunkZ + random.nextInt(16);
						(new WorldGenMinable(boneOre.blockID, 3)).generate(world, random, boneOreX, boneOreY, boneOreZ);
				}

I downloaded JDK and all (MCP, Eclipse) and using Notepad ++, i made a block called 'test' and following the instructions, i have a mod_Test.java and a Test.java. I imported them into eclipse, and i realize i need to compile them into mod_Test.class and Test.class. Is there a way to do that with eclipse? I know there is a way with command prompt, but Is there an easier way with eclipse? Also, once i have the class files, what do I do with them? How would I know they made it successfuly into minecraft.

1. Download MCP
2. Make a folder with MCP inside it, this will be your workspace
3. Get a clean minecraft.jar, delete META-INF and install modloader to it
4. Copy and paste the entire bin folder to your MCP directory > jars
5. Go back to your MCP directory, and run decompile.bat
6. Once decompiled, open eclipse and set the workspace to your MCP directory\eclipse
7. Create all your .java files within eclipse, do some coding...
8. Go to File at the top bar and hit save all (You'll need to fix something if it says you have more than 2 errors)
9. Go back to your MCP directory and run recompile.bat
10. Run startclient.bat and test your game to see if your mod works
11. If so, close client, and run reobfuscate.bat (This turns all the .java you made into .class and places them into your MCP directory > reobf > minecraft)
12. add all files into a zip file container (don't forget to include your textures if you made any)
13. either install the contents of the zip file into your .jar or just copy and paste the whole zip into mods folder located in .minecraft, depending on how you have things set up (.jar if only using modloader, mods folder if using forge)
14. Congrats.

After taking a look at some mods, I see they have a zip folder with the mod's name on it, and inside are class files. but for example, like buildcraft 3.1.5 energy folder has a folder at the top, 'buildcraft', with the content in nice labeled class form. then beneath that is buildcraftenergy.class, which i could relate to 'block.class' from the tutorials. then is the mod_buildcraftenergy.class, which i could relate to 'mod_block.class'. In a zip folder, after compiling, would I just put 'block.class and mod_block.class in a zip folder and put it in the mods folder of a .minecraft? (using multimc)

mine says " Java JDK is not installed ! Please install java JDK from http://java.oracle.com"

Please help!!!

Quote from myoblastic

Thanks for the help!


-Raggarcowboy: So i dont' need notepad++. oh well, i use it in place of wordpad anyways.

-ZeroLevels: Thanks for the tutorial! I imported mod_test.java into eclipse and wrote test.java in eclipse. But i'm getting a lot of errors. I think i shouldn't report them on this thread, but most of them (22) are like 'x cannot be resolved to a type/variable'.

Also, if i wanted to check if my block made it successfully into the game, how would i do that? Would i just install TMI or something? I also want to check if the recipe i made is working.

Quote from myoblastic

Nah i mean it isn't private code (code for a block named Test) but i remember that in the OP there was a line stating code shouldn't be put here?

Here it is anyways. In spoilers so people won't get annoyed!

mod_Test.java

package net.minecraft.src;
public class mod_Test extends BaseMod
{
public static final Test = new Test(200,
10).setBlockName("Test").setHardness(2F).setResistance(1000F).setLightValue(15F);
  public void load()
  {
	ModLoader.registerBlock(Test);
	ModLoader.addName(Test, "Faith");
	ModLoader.addRecipe(new ItemStack(Test, 3), new Object [] {"#@#", "@#@", "#@#",
	Character.valueOf('#'), Block.stone, Character.valueOf('@'), Block.dirt});
  
  }

  public String getVersion()
  {
	return "1.2.5";

  }

}

Test.java

package net.minecraft.src;
importjava.util.Random;

public class Test extends Block
{
public Test(int i, int j)
{
super(i, j, Material.wood);
   }

public int idDropped(int i, Random random, int j)
{
return mod_Test.Test.blockID;
}
public int quantityDropped(Random random)
{
return 1;
}}

I think error code? i just highlighted all the errors in eclipse and pasted them here.
