Here's the code with the crash:

The mod_DirtPlus.java

package net.minecraft.src;

public class mod_DirtPlus extends BaseMod

		public static final Block DirtBrick = new BlockDirtBrick(171, 0).setBlockName("Dirt Bricks").setHardness(2F).setResistance(4F);

				DirtStairs.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/DirtPlus/Dirt.png");
				DirtBrick.blockIndexInTexture = ModLoader.addOverride ("/terrain.png", "/DirtPlus/DirtBrick.png");
				DirtSlab.blockIndexInTexture = ModLoader.addOverride ("/terrain.png", "/DirtPlus/Dirt.png");
				ModLoader.registerBlock(DirtStairs);
				ModLoader.registerBlock(DirtBrick);
				ModLoader.registerBlock(DirtSlab);
				ModLoader.addName(DirtStairs, "Dirt Stairs");

}

The crash is in my previous post.

And by the way, when I try to generate something I get the following message:

Remove all the extra " " sets as they're not needed.

ModLoader.addRecipe(new ItemStack(Block.dirt, 3), new Object [] {"#  ", Character.valueOf('#'), DirtSlab});

For the generation, I've fixed it now, but the forum was changing the code I had written. It needs to be like this:

for(int k = 0; k < 10; k++)

Quote from demcmd

It says "javac 1.6.0_29"

EDIT: I searched "Java" in my search bar. Got something called "Java VisualVM". Is that right?

Can you open Eclipse without getting an error message about not having the JDK installed? I am fairly sure now that most, if not all, Java stuff comes pre-packaged with OS X. I think that JavaVisualVM is right. As it is the Java Virtual Machine, which is what is used when modding to test the mod in the client(I use it, not sure about anyone else though).

Crap. Where do I get to Eclipse? (I know, I'm not this good when it comes to computers).

Get it from here. It's the third one on the list, "Eclipse IDE For Java Developers".

Now I get a crash with recompiling, instead of startclient.bat.

I meant the whole empty sets of quotation marks. Your recipes should look something like this:

				ModLoader.addRecipe(new ItemStack(DirtStairs, 1), new Object []
{"#  ", "## ", "###", Character.valueOf('#'), Block.dirt});

                ModLoader.addRecipe(new ItemStack(Block.dirt, 6), new Object []
{"#", Character.valueOf('#'), DirtStairs});

Please put your code and error in a SPOILER.

Run getmodsource.bat/sh
All of your code will then be in "modsrc" in the mcp directory.
Check all of your classes are in that directory, if they aren't go and get the missing ones from src.
Copy the "modsrc" folder to another directory outside of mcp.
Run cleanup.bat/sh.
Wait until there is a new version of mcp to be downloaded. It normally takes 3 days to a week.
Run updatemcp.bat/sh
Get a jar of the new version of minecraft and install the latest ModLoader for that version.
Put it in jars/bin along with all the other jars like lwjgl, make sure you get them from your .minecraft directory because they update with the minecraft.jar.
Decompile again.
Put all the .java's from "modsrc" back into src with all of the other client/server files(depending on what your mod is)
Fix any errors you get with the new version of MCP and ModLoader.
You're done!

Would that work with Eclipse .class files?

I'm not sure what you mean. Do you mean class files that eclipse has built from the .javas?

Um, it didn't seem to work, no errors, but it will still spawn below the water.
my code:

package net.minecraft.src;

import java.util.Random;

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

		public boolean generate(World world, Random random, int i, int j, int k)
		{

if(world.getBlockId(i, j, k) != Block.waterStill.blockID && world.getBlockId(i, j + 1, k) !=

0)
   {
		  return false;
   }
				int wood = Block.planks.blockID;

				world.setBlockWithNotify(i, j, k, wood);
				world.setBlockWithNotify(i, j, k +1, wood);
				world.setBlockWithNotify(i, j, k +2, wood);
				world.setBlockWithNotify(i, j, k +3, wood);
				world.setBlockWithNotify(i, j, k +4, wood);
				world.setBlockWithNotify(i, j, k +5, wood);
				world.setBlockWithNotify(i, j, k +6, wood);
				world.setBlockWithNotify(i, j, k +7, wood);

			
				return true;
		}  
}

I've been testing a few things, and I've come up with this:

public boolean generate(World world, Random random, int i, int j, int k)
{

if(world.getBlockId(i, j, k) == Block.waterStill.blockID && world.getBlockId(i, j + 1, k) == 0)
{
int wood = Block.planks.blockID;

world.setBlockWithNotify(i, j, k, wood);
world.setBlockWithNotify(i, j, k +1, wood);
world.setBlockWithNotify(i, j, k +2, wood);
world.setBlockWithNotify(i, j, k +3, wood);
world.setBlockWithNotify(i, j, k +4, wood);
world.setBlockWithNotify(i, j, k +5, wood);
world.setBlockWithNotify(i, j, k +6, wood);
world.setBlockWithNotify(i, j, k +7, wood);
return true;
}
return false;

}



}

That works fine for me

You'll just have to change the check for air(0) to a higher int if you want your ship deeper. I want to say thanks for asking me about this, because I need to do the same sort of thing in Undead+.

Get it from here. It's the third one on the list, "Eclipse IDE For Java Developers".

I hope to god that a .tar.gz file works on this system...

EDIT: Well I got it downloaded. Didn't crash. Anything else I should know?

Just set your workspace to the "eclipse" folder in MCP and it will set everything else up for you. Then you can just create your new mod_ class, etc, in the net.minecraft.src package.

Right, thanks, and it is no problem to pester you for help

also; back to the stairs question: do you know how to make them spawn facing the right way?

I'm not really sure. Maybe try using the world.setBlockAndMetadataWithNotify method like I used as an example in the world gen tut. Then just change the 1 to 2, 3 or 4 and it should change direction.

Would you be able to add a tut on how to make custom fences

Yeah, that seems to have done it, thanks

but just so you know; it goes from 0-7 as you have to include the upside down ones.

Character.valueOf('#') says that if you use # in your crafting recipe it will be the item you type after it, which will now be a block of dirt (Block.dirt)

I don't understand :l

Block animations are hard. I'm currently working with someone trying to do them and get them working well.

It is on the list to do, I'll get to it when I get to it.

Quote from darkthynder

The dirt slab works now, only the upper side of the block is black, is there any way to fix that?

And I added dirt glass, recompile.bat gives NO errors, startclient.bat gives NO errors too, however when I place dirt in the crafting table to give me dirt glass, the client crashes when the recipe's finished.

I placed it like the following:
[][][]
[] []
[][]

and if you place the last piece:
[][][]
[] []
[][][]
then It crashes.

here's the crash:

A crash at the crafting grid normally indicates something wrong with the texture/s of the block. The crash report also indicates this. Make sure that it is the correct size, format and in the right location.

They are quite difficult, especially to make a tutorial on. I can try once I get rid of some of the tutorials on the list already.

Quote from RainbowLuigi281

Sorry for the long wait and yes.

I think we were talking about mobs? Something like this should work.

spawnableCreatureList.add(new SpawnListEntry(net.minecraft.src.EntityNamehere.class, 5, 4, 4));

Put that in the constructor of your biome class. The three ints at the end are the same as ModLoader's addSpawn method.
Probability of spawning in chunk - Minimum in Chunk - Maximum in Chunk

Quote from demcmd

ModLoader.addRecipe(new ItemStack(Namehere, 1), new Object [] {"#", Character.valueOf('#'), Block.dirt});

I need more information about this. What is Character.valueOf? And Block.dirt});?

Character.valueOf is part of Java. More specifically, char. It is a primitive data type, and is a single 16-bit Unicode Character. We use it in Minecraft for getting the values of characters that we add into a string/s for the recipe of an item. So then we can assign an ingredient to that symbol/character in the recipe, then the code in CraftingManager.java reads it all, and makes it an actual recipe in the game.

Block.dirt is simply the name of the an instance in Block.java called "dirt". As I said above, It is used by CraftingManager.java to make an actual recipe. Block.dirt in code, is the same thing as having a dirt block in your inventory, or even just the world around.

Does this clear up a few things for you?
