With my previous post in mind, here is my ItemCoaxiumRod.java file, there is one problem: The item itself isn't available in the Creative inventory. When I add the ModItems.ITEMS.add(this), I get a NullPointerException (crash log below). I am declaring my Item in my ModItems class, in init package like this:
package com.sm.FirstMod.items;

Do I just copy and paste the methods from the extended class into my class and change the return values? EX: If I were to extend ItemReactorUranium, would I just copy/paste the methods into my CustomFuel class? I'm assuming I need to @Override the methods... If so, do I do that with the implemented class, IReactorComponent?
