Now that you have created an NPC that talks to the player, it is time to allow the NPC to help the player. In this chapter, we will use the NPC as a shop owner, displaying items for the user to buy. Before we do this, the user is going to need some sort of currency to buy the items. We will cover the following topics in this chapter:
Setting and getting gold instances
Item data
The shop screen framework
The item button framework
Linking the item data
