Overview of this book

Are you looking at implementing gamification techniques for your business and wondering where to get a complete rundown of all the tricks and techniques? Well, you have come to the right place! This book will start right from the basics such as gameplay elements and their functionalities before gradually moving onto creating your first gamification project from scratch. You’ll be given the tools and shown how to perform various techniques for creating gamified applications in different contexts. Finally, you will implement various game elements into Unity, publish your own task management application, and get to know the best practices and approaches when designing gamified experiences.

Data persistence in our application


In the previous chapter, we implemented most of the logic of our application. However, every time the user closes the application, all their tasks disappear. This is because our application is not persisting data.

To make data persistent, we need in some way to store it. The first intuitive way is to store the data locally, which means saving to a file.

PlayerPrefs in Unity

Unity offers a quick and easy way to store data persistently by using PlayerPrefs, a special class where there are functions to save primitives, such as integers or strings. In the following examples, we will work with strings, but the process is the same for all the other primitives.

The Set function

It is possible to save the data by using the following line:

PlayerPrefs.SetString("Your Key", "Your Value"); 

Basically, it takes a key and a value. The key is important, because we need it when we need to get the value back, maybe in another session (the user used the application, closed...
