Database Suggestion

Good day fellow creators!

Our team is on a school project of creating a mini android mobile RPG, however we don't know how we can create Database for Users. If you are familiar with Plants Vs Zombies, you can play it offline and still have ability to create a new user, save its progress or load a different user. We are open to using any third-party softwares so long they have free version, lol.

Thank you in advance!

 

Unity has a tutorial: Introduction to Saving and Loading

 

Couple of possibilities:

1. Server database. This requires a server and running some free database (such as MySQL, Postgres, etc). That way any client started anywhere will be able to fetch or switch to any given user and any user can be persisted to the database. Unfortunately this scenario also requires an application server to handle the data and persist to the database. This is the the most complex but offers the greatest flexibility and progress/users data can be hardly lost.
2. PlayerPrefs - there is a class in Unity to set floats, booleans, ints and strings to a local storage on whatever device is running your application. I use it for lots of things and it is good enough for just client side data. Also you need to know same data can't be replicated on multiple devices with this method, it is just on the device it was stored. So saving a user on device 1 and then loading it on device 2 is not good with this method.
3. Saving file on disk - you can manually create files on the disk and write in them, but I don't recommend it. It is much more complex and error prone than PlayerPrefs.

 

If you really need a database try Firebase. It can use many different forms of authentication including Google, & Facebook.Its pretty easy to set up too. Its free.
