I am trying to make a very simple mod by just copying tutorials, and every time, I get this error message.

Please keep in mind I know just about nothing about modding Minecraft.

You failed to follow the tutorial, or the tutorial is crap.

Somehow you're assiging a int, to a Material... figure it out. Sure as hell can't help you without seeing it.

And we shouldnt really help you as you should be able yourself if you know some basic java.

Oh silly me, I should of included the code.

package net.minecraft.src;

import net.minecraft.src.forge.*;

public class BlockTitanium extends Block implements ITextureProvider
{
        public BlockTitanium(int i, int j)
        {
                super(i, j, Material.rock);
        }

        public String getTextureFile()
        {
                return "/testmod/blocks/test sheet.png";
        }
}

package net.minecraft.src;

import net.minecraft.src.forge.*;

public class mod_Testing extends BaseMod
{
        public static final Block oreTitanium = new BlockTitanium(123, 0).setHardness(3F).setResistance(5F).setStepSound(Block.soundStoneFootstep).setBlockName("oreTitanium");
        

        public mod_Testing()
        {

        }

        public void load()
        {
        MinecraftForgeClient.preloadTexture("/testmod/blocks/test sheet.png");
                
                ModLoader.registerBlock(oreTitanium);
                ModLoader.addName(oreTitanium, "Titanium Ore");
                
        }

        public String getVersion()
        {
        return "1.0.0";
        }
}

Yay for not providing anything related to what the error is!

Read the error -.-

...

 

Thanks for the help..

 

 

I guess.

Well, the super() call probably needs the args in a different order. Or you're calling the block constructor with the wrong args.
