Hello! I have been trying to register my ore into the ore dictionary. When I try to run minecraft, the following stacktrace for the error appears:

The code I use to register into the dictionary is

OreDictionary.registerOre("oreGemEnd", ORef.oreGemEnd);

ORef is where I keep all the references to my items.

 

I think this is a forge error, but I cannot be certain.

Ore dictionary has to go in your init method, not your pre-init. This is not a forge bug. I believe it's because registering blocks actually registers an ItemStack, which uses Item.getItemFromBlock which returns null during the Pre-Initialisation stage of Minecraft.

My registration to the dictionary goes in init. It is in the correct place unless it needs to go into post-init.

 

EDIT: I tried using ore dictionary in post-init, this gave the same error.

My bad, I skimmed over the crash log. When do you initialise and register oreGemEnd to the GameRegistry?

Could we see the ORef file and BcwadsworthWorld.java? It looks like your ItemStack you're registering might be wrong.

For no apparent reason, the problem has fixed itself! Thanks to all of you who tried!
