[SOLVED][1.6.4] Can't get GameRegistry.findItem to work :/

Posted March 1, 201411 yr

Hi,

I'm new to Forge Modding and wanted to make a Thaumcraft Addon which add new wand rods and caps.

Everything is working fine except one thing: I can't access the items from Thaumcraft, but I need to do that for

my recipes.

I try it with

public static Item thaumResource = GameRegistry.findItem("Thaumcraft", "ItemResource");
AWLog.AWLogger.log(Level.INFO, "ItemResource: " + thaumcraftItem.thaumResource); //Just prints out messages for debugging

//ItemResource: thaumcraft.common.items.ItemResource@59ec437 (This it what appears in the console)

But when I the want to make a recipe with that like that:

GameRegistry.addShapelessRecipe(new ItemStack(thaumcraftItem.thaumResource, 1, 0), new Object[]{Item.diamond});

It crashes with this report:

And when I make an ItemStack with that directly:

public static ItemStack thaumResource = new ItemStack(GameRegistry.findItem("Thaumcraft", "ItemResource"));

It returns this in the console:

ItemResource: 1xitem.ItemResource@0

But when I try to make recipe with that:

GameRegistry.addShapelessRecipe(thaumcraftItem.thaumResource, new Object[]{Item.diamond});

It crashes with this error:
