Hello.

 

I am trying to use wuppy's tutorial book on modding mc 1.8 with eclipse and forge.

 

Everything in the file and both item classes is fine compared to what is in the book, it follows it to the letter; but yet I receive this message when trying to run minecraft through the eclipse:

 

AL lib: (EE) alc_cleanup: 1 device not closed

 

Here is the crash report:

Would this be fixed by changing the code lines

 

public String getUnlocalizedName(ItemStack par1ItemStack)

{

return super.getUnlocalizedName() + "." + metaNames[par1ItemStack.getItemDamage()];

}

 

to "par2ItemStack"?

Here is my item class code. Can someone please tell me what to change? I just want to set metadata to the two items: samdust and samingot, within the class SamItemGeneric:

 

1    package com.nathantestmod;

2

3    import net.minecraft.item.Item;

4    import net.minecraft.item.ItemStack;

5

6    import java.util.List;

7

8    import net.minecraft.client.resources.model.ModelBakery;

9    import net.minecraft.creativetab.CreativeTabs;

10  import net.minecraftforge.fml.common.registry.GameRegistry;

11  import net.minecraftforge.fml.relauncher.Side;

12  import net.minecraftforge.fml.relauncher.SideOnly;

13 

14  public class ItemSamGeneric extends Item

15  {

16    private static String name = "sam";

17   private static String[] metaNames = { "dust", "ingot" };

18

19   public ItemSamGeneric()

20   {

21   GameRegistry.registerItem(this,  name);

22   setUnlocalizedName(NathanTestMod.MODID + "_" + name);

23   setCreativeTab(CreativeTabs.tabMisc);

24   setHasSubtypes(true);

25   }

26

27   public String getName()

28   {

29   return name;

30   }

31

32   @Override

33   public String getUnlocalizedName(ItemStack par1ItemStack)

34   {

35   return super.getUnlocalizedName() + "." + metaNames[par1ItemStack.getItemDamage()];

36   }

37   public static String getNameFromDamage(int damage)

38   {

39           return name + metaNames[damage];

40   }

41   public static void registerVariants()

42   {

43   String[] variantNames = new String[metaNames.length];

44   for (int i = 0; i < metaNames.length; i++)

45   {

46   variantNames = NathanTestMod.MODID + ":" + getNameFromDamage(i);

47   }

48   ModelBakery.addVariantName(NathanTestMod.sam, variantNames);

49   }

50   @SideOnly(Side.CLIENT)

51   @Override

52    public void getSubItems(Item itemIn, CreativeTabs tab, List subItems)

53   {

54   for (int i = 0; i < metaNames.length; ++i)

55   {

56   subItems.add(new ItemStack(itemIn, 1, i));

57   }

58   }

59

60  }

Ok I'm sorry.

 

Here's the first method, right between the imports and the recipes in the Init Method.

 

public class NathanTestMod

{

public static final String MODID = "nathantestmod";

public static final String VERSION = "1.0";

public static Item key;

public static Item sam;

 

@EventHandler

public void PreInit(FMLPreInitializationEvent event)

{

key = new ItemKey();

 

sam = new ItemSamGeneric();

 

if(event.getSide() == Side.CLIENT)

{

ItemKey.registerVariants();

}

 

and here's the postInit method:

 

@EventHandler

public void PostInit(FMLPostInitializationEvent event)

{

if(event.getSide() == Side.CLIENT)

{

RenderItem renderItem = Minecraft.getMinecraft().getRenderItem();

renderItem.getItemModelMesher().register(key,  0, new ModelResourceLocation(MODID + ":" + ((ItemKey) key).getNameFromDamage(0), "inventory"));

renderItem.getItemModelMesher().register(key,  1, new ModelResourceLocation(MODID + ":" + ((ItemKey) key).getNameFromDamage(1), "inventory"));

renderItem.getItemModelMesher().register(sam,  0, new ModelResourceLocation(MODID + ":" + ((ItemKey) sam).getNameFromDamage(0), "inventory"));

renderItem.getItemModelMesher().register(sam,  1, new ModelResourceLocation(MODID + ":" + ((ItemKey) sam).getNameFromDamage(1), "inventory"));

}

}

 

The weird thing is, eclipse showed no errors in any of the classes.

Ohhhh... I figured it out. LOL Thanks anyway.
