Achievement Item collection

Overview

In Sprint 1 we did an achievement for the user to pick up items. This achievement is achieved when the user has collected a certain number of items. This is our preliminary frame presentation. This content will be optimized by subsequent SprinTs.

Classes can be unit test

When the game starts, we will constantly monitor what items you have in your backpack and how many. Quantities are stackable. The user has a backpack for an item, but retrieves it when he consumes a portion of it. In this way, the number of items in the background will always be superimposed, and we will count how many times the user collects this item in the whole cycle.
