[Solved] Minecraft crashes when trying to mine anything, please help!

...any block with my new tool. :O

To learn the modloader basics I've been doing your (Zid's) ModLoader tutorials at the forums, and I've been wrestling with a little problem.
Allright, I'll try to explain it as clear as possible:

So far I've made:
1. Aurantium Ore.
2. Aurantium Block.
3. Aurantium (=Item).
4. Aurantium Tools.

Now, everything went allright until I got to the tools. I made the tools and it worked great, but then I thought; "hm, why not make it so you can mine the ore and block with JUST the diamond and Aurantium tools?", so I tried making that but my minecraft crashed on the moment I wanted to harvest ANY BLOCK with it, after adding effectivity of Pickaxes;

Main Question: I just want pickaxes to become more effective on those two ores. What to do? :O

The error I got was:

Code:

Before continuing to adding to block to the world generation, I'd love having this fixed. Any quick help would be appreciated.

These are the NEW files so far:

BlockAurantiumOre.java

Code:

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

public class BlockAurantiumOre extends Block
{
    protected BlockAurantiumOre(int i, int j)
    {
        super(i, j, Material.iron);
    }
   
    public int idDropped(int i, Random random)
    {
        return mod_Aurantium.aurantiumItem.shiftedIndex;
    }
   
    public int quantityDropped(Random random)
    {
        return 2 + random.nextInt(2);
    }
}

BlockAurantium.java

Code:

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

public class BlockAurantium extends Block
{
    protected BlockAurantium(int i, int j)
    {
        super(i, j, Material.iron);

ItemAurantium.java

public class ItemAurantium extends Item
{
    public ItemAurantium(int i)
    {
        super(i);
        maxStackSize = 64;
    }
}

To EnumToolMaterial.java I've added:

Code:

    WOOD("WOOD", 0, 0, 59, 2.0F, 0),
    STONE("STONE", 1, 1, 131, 4F, 1),
    IRON("IRON", 2, 2, 250, 6F, 2),
    EMERALD("EMERALD", 3, 3, 1561, 8F, 3),
    GOLD("GOLD", 4, 0, 32, 12F, 0),
    AURANTIUM("AURANTIUM", 5, 4, 3321, 16F, 3);

To ItemPickaxe.java I've added:

Code:


        if(block == mod_Aurantium.aurantiumBlock || block == mod_Aurantium.aurantiumOre)
        {
            return toolMaterial.getHarvestLevel() >= 3;
        }
        if(block == Block.obsidian)
        {
            return toolMaterial.getHarvestLevel() >= 3;
        }

mod_Aurantium.aurantiumOre, mod_Aurantium.aurantiumBlock

After adding that 'mod_Aurantium.aurantiumOre, mod_Aurantium.aurantiumBlock' to the end of that file, right after 'Block.blockLapis' in the 'blocksEffectiveAgainst' array, it started crashing. Before that it worked perfectly fine!

Test it out in Test_Game.bat. (Paste all your new textures in their proper folders in the /temp/ folder) See if it will work then, I have a feeling you're getting the same Error as I am.

Did that already. Didn't work. :O
No, it's something with the code.

Plus, I'm using MCP v3.1 so for me it's 'startclient.bat', I believe. :O
I'm not sure though...

Any other ideas?

I'll post this thread at the official forum too, just to see if I get more responses. :O

Make their hardness minus one level from Obsidian. Solved. Delete the event.

Euuhm, no. This way it takes quite long to harvest the block, it will only be harvest-able with the diamond and 'aurantium' pickaxes, but even with those it'll take quite long.
Thanks for the help though, but what I want to find out is how to make ModLoader tools become effective against blocks without the full thing crashing.

If I'd done this without ModLoader I'm pretty sure it would've worked fine. I just need a way around this, or something that can recreate the same effect. :O (Which could be lowering hardness but you'd still mine the specific ModLoader block very slow, even with the effective tools.)

You have to use ToolUtils, it's impossible otherwise, unless you want the way rocky said.

Thank you sir, that did the trick, just to be sure I didn't mess up anything; could you please give me an example of what rocky actually wanted me to do? It's possible I didn't really understand what he was saying. :O

Nvm, I've got it.
Thanks for all the help!

Lock/Trash this thread please, problem solved.

I'm not sure I assume it works though.

Ziddia wrote:I'm not sure I assume it works though.

Well it was a bit ... slow, but just lowering the Hardness did the trick.
I've just got to deal with it for now, I guess.

Thanks, though.

ToolUtils hasn't been updated since 1.3. I don't know what you can do.
