While making my mod, i'm trying to make everything configurable in parameters file, including the ID of item that drops when mining the block. I've got an ID error. Trying to solve it, i've noticed that the item ID used in a game itself is given ID + 256. So, if I want to set specified ID of item, and use that ID correctly even before initialisation of item, should i use new MyItem(myItemID-256)? Will it always works (if ID is not yet occupied)?
