Alrighty. Let's see here.

Firstly, you're making a new block, so you need to tell it that in your declaration. So, your public static final should look something like this:

public static final Block Test = new Test(200, 10).setBlockName("Test").setHardness(2F).setResistance(1000F).setLightValue(15F);

And since you have the number next to the blockID set to 10, it'll come out looking like all sides are made of the bottom of TNT. But this is a test, so that's fine.

That I can tell, that's really the only problem. But all those errors look like it's not registering that ModLoader is installed to the minecraft.jar... Did you install it to the .jar before decompiling?

Are you making other tools besides a Titanium sword?

Quote from DragoonScull

Maybe you should read the tutorial about tools in the second post. btw i only read the block tutorial too, so its just a tipp...

But a question: should the block only drop a item when you use a golden pickaxe or better (iron, diamond) or when really only use the gold pickaxe?

Quote from DragoonScull

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 place the block it has the default texture  ! >.<

I meant to say that I got your point in my previous post. My bad. Yes. I understand completely.



No. But I have an idea. I actually have a texture drawn up for a new flower and crop I want to add. I'll try to code it in and I'll share my experience.

Quote from DragoonScull

There is no BlockPlanks.java or anything like that.. i would get an error like "Cannot find symbol" or so, if i do it like you said...
My mod works proper, really. Planks are called wood and wood is called log in MineCraft code.. look:

/* origianal code from Block.java*/

[...]

planks = (new BlockWood(5)).setHardness(2.0F).setResistance(5F).setStepSound(soundWoodFootstep)
.setBlockName("wood").setRequiresSelfNotify();		  
[...]
wood = (new BlockLog(17)).setHardness(2.0F).setStepSound(soundWoodFootstep)
.setBlockName("log").setRequiresSelfNotify();
[...]

And my mod if you want to try it out. And if you do it: it just works in creative and try to place an undestroyable birch wood block..

btw try it with iron-weapons (silver) ^^
I have no idea how to realize the main problem..
I just found the code of the pickaxe tools.. Maybe it is possible to modify it but that is not the idea of ModLoader..

Do you ever heard something about "spawneggs"? maybe you should take a look in their code..
EDIT1: spawneggs are called "MonsterPlacer" in MineCraft code:

/*ItemMonsterPlacer.java*/
