title: Modded Minecraft error: No such method?
body: <p>When loading my first mod I am getting the following error: </p>
  
  <blockquote>
    <p>Error: cpw.mods.fml.common.LoaderException: java.lang.NoSuchMethodError: com.haxium.basicmod.obsidian.armor.ItemObsidianPickaxe.setTextureName(Ljava/lang/String;)Lnet/minecraft/item/Item;
    I also get the same error with ItemObsidianPickaxe.setUnlocalizedName(Ljava/lang/String;)Lnet/minecraft/item/Item;</p>
  </blockquote>
  
  <p>Does anyone have any ideas why?</p>
  
  <p>Here is the ItemObisidianPickaxe code:</p>
  
  <pre><code>package com.haxium.basicmod.obsidian.armor;
  
  import net.minecraft.item.ItemPickaxe;
  import com.haxium.basicmod.obsidian.armor.*;
  
  public class ItemObsidianPickaxe extends ItemPickaxe {
      public ItemObsidianPickaxe(ToolMaterial material, String name) {
          super(material);
          setUnlocalizedName("obsidian_armor_" + name);
          setTextureName("obsidian_armor:" + name);
      }
  }
  </code></pre>
