Chapter 10. Inventory System and Pickup Items

We want our player to be able to pick up items from the game world. In this chapter, we will code and design a backpack for our player to store items. We will display what the player is carrying in the pack when the user presses the I key.

As a data representation, we can use the TMap<FString, int> items covered in the previous chapter to store our items. When the player picks up an item, we add it to the map. If the item is already in the map, we just increase its value by the quantity of the new items picked up.
