This are my classes:

package source.items;

public class ItemInfo {

   public static final String TEXTURE_LOCATION = "example";

   public static final String WAND_NAME = "Espada de Obsidiana";
   public static final String WAND_ICON = "swordObsidian";


}

what's the problem? I can't give texture to my item, this is the code (I will show you again):

package source.items;

import net.minecraft.block.Block;
import net.minecraft.client.renderer.texture.IconRegister;
import net.minecraft.item.EnumToolMaterial;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.item.ItemSword;
import cpw.mods.fml.common.registry.GameRegistry;
import cpw.mods.fml.common.registry.LanguageRegistry;
import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;

public class Items {

 public static void init() { 
     EspadaDeObsidiana = new ItemSword(ItemInfo.WAND_ID, EnumToolMaterial.EMERALD).setUnlocalizedName("EspadaDeObsidiana");
     
}

public static Item EspadaDeObsidiana;
public static void addNames() { 
	LanguageRegistry.addName(new ItemStack(EspadaDeObsidiana, 1), ItemInfo.WAND_NAME); 
	}

@SideOnly(Side.CLIENT) 
public void registerIcons(IconRegister register) { 
   {
        register.registerIcon(ItemInfo.TEXTURE_LOCATION + ":" + ItemInfo.WAND_ICON);} 
   }

public static void registerRecipes() { 
	GameRegistry.addRecipe(new ItemStack (EspadaDeObsidiana, 1), 
	    new Object[] {  " O ", 
	                    " O ", 
	                    " / ", 


	                    'O', Block.obsidian, 
	                    '/', Item.stick, 

	             });
   }

}

Whats the crash report? You say it crashes but give us no information about the crash. What is suppose to happen when the crash happens? Just giving the code tells us nothing about your crash. We could sit here all day telling whats wrong with your code but still not fix the crash.

1) Check to make sure that the block / item is not null when you pass it to the itemstack constructor.

2) Look at the ItemStack constructor at the line the crash report indicates to figure out what object might be null.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

I finded two code lines that make mention to the ItemStack in the crash report:

at net.minecraft.item.ItemStack.<init>(ItemStack.java:82)

both says the same thing but I don't find the object that's null

What is the code at that line?

 

That's why I said "Look at the ItemStack constructor"

Hmmm. If I were a betting person, I'd bet you don't program in java much.

 

Why? Oh, Why did you put your mod in package source? And then put your Items and such in different packages? None of that is proper java.

 

Use a package such as com.eaglenator.itz, or something similar and put all your classes in the package.

 

Also, why do you create and pass an Object Array to addRecipe. The signature expects multiple parameters, starting with an ItemStack instance and including the 3 Strings, and repeated Chars, and Item/Block/ItemStack instances in the proper order.

Try something like this:

GameRegistry.addShapedRecipe(new ItemStack(anItem), new String[]{"ABC", "CBA", " B "}, 'A', Items.arrow, 'B', Items.boat, 'C', Items.bone);

or

GameRegistry.addShapedRecipe(new ItemStack(anItem), "ABC", "CBA", " B ", 'A', Items.arrow, 'B', Items.boat, 'C', Items.bone);

 

It's not rocket science, but is precise.

-S- (if I helped, please click Thank and applaud)

ItemStack constructor? you mean to ItemStack.java or to the codes with "ItemStack".

 

Fox man.

 

at net.minecraft.item.ItemStack.<init>(ItemStack.java:82)

 

Go learn Java.

Your package structure once i looked at it was enough to show you dont really know java. I suggest you learn java enough that you can make sence of the minecraft code even if you dont fully understand it that way you can also figure things like this out.
