Adding GameObjects to the mix

For our example, we’re going to add GameObjects to each Creator class variation we’ve already built so the items not only have a code component but also appear in the game scene.
Because the main building block of our item classes is the IItem interface, we’re going to make each of our concrete items a MonoBehaviour so Unity treats them as components.

In an ideal world, we would have the item classes own their own GameObjects, but C# doesn’t allow interfaces to have instance fields.
If you’re asking yourself why I don’t just add an instance field to each item class and assign it a GameObject in its...
