Your unlocalized name for both items are the same. The pickaxe's name should be changed from ".setUnlocalizedName("ItemDemoniteSword")" to ".setUnlocalizedName("ItemDemonitePickaxe")"
Hello, I have been having trouble creating a dimension, and I can't seem to find much documentation on the subject. I think the dimension is being created and registered, but the teleporter doesn't work. I am sort of new to modding with 1.10.2, but knowing of 1.7 modding. Thanks!
