An era where game prototypes are created quickly with AI! If you're struggling to add backend services afterwards?
This course implements login, storage, rankings, bulletin boards, and mail step-by-step using Firebase.
From solo development to employment, being able to handle the backend changes what you can build.
Don't stop at the prototype; complete it by integrating login, storage, ranking, bulletin boards, and mail.
Learn the know-how to implement and operate everything from login to storage, rankings, mail, and security on your own, even without your own server.
Among applicants who only handle the client-side, a completed project that integrates data design, security, and asynchronous processing will serve as a strong point of differentiation.
Once you log in, the Watermelon Game begins. You compete in the rankings with the scores you earn and chat with other users on the bulletin board. When you even receive rewards through the mailbox, a game you played alone transforms into a complete game equipped with login, storage, rankings, bulletin boards, and mail.
I will show you directly in the console how the Watermelon Game runs on Firebase's core features.
We have structured the most commonly used features in game development around hands-on practice. Once you master these essential features, you can easily add other Firebase features as well.
Fruit dragging, dropping, and merging, score and high score management
Email/password sign-up and login, nickname management
Saving and loading user-specific data in the database
Register high score/nickname, view top N and my rank
Create·List·Edit·Delete, manage only own posts
Admin sending tools, reward collection, new mail red dot notification
Read and write only one's own data and posts
Real-time adjustment of score multiplier and drop interval without rebuilding
async/await and UniTask patterns instead of callbacks
Verifying on real devices with APK builds, Crashlytics error reporting
Even code that worked perfectly during initial development starts to get messy as you add more features one by one. This course covers how to divide responsibilities into Services and Repositories as the project scales. By separating code into In-game, UI, Manager, Repository, and Service layers, we build a structure that is easy to scale and maintain.
Each class is responsible for only one task. Therefore, modifying one part does not affect other functions.
Roles are divided into In-game, UI, Manager, Repository, and Service, making it easy to see where each piece of code is at a glance.
Just as the ranking and board systems were built with the same structure, you can follow the same pattern when adding new systems later.
In the process of integrating Firebase features, you will naturally master design patterns frequently used in game development. We explain why these patterns are used on the spot, along with the reasoning behind them.
Divide classes so that each handles only one task, preventing modifications from spreading to other functions.
Share objects that are accessed throughout the scene, such as the GameManager or authentication service, as a single instance.
Loosely couple them using events so that the UI updates automatically when the score changes.
Streamline Firebase's asynchronous callbacks into UniTask's async/await flow.
Divide UI, game rules, and data storage into layers to ensure dependencies flow in a single direction.
Cache frequently accessed data to reduce the number of Firestore reads and costs.
It was my first time building a server using something like Firebase, and it was a great experience. As someone who has only ever developed game clients with Unity, the backend always felt like someone else's job, but I started this because I needed ranking and save functions. After finishing the course, I felt I absolutely had to leave a review. I've taken a few Firebase courses before, but this was the cleanest one I've seen. It doesn't just stop at making things work; it points out exactly where the code should be placed, helping you develop a sense for building maintainable structures as you follow along. The Notion syllabus was meticulous, and the code comments were well-written, which helped a lot during review. I also liked that the instructor didn't gloss over things and implemented everything together until the end. The only slight disappointment was the lack of a mail/postbox feature. Since reward mail is almost essential in games, it would have been perfect if that were included. However, I think I can try building it myself by applying the structure I learned. I highly recommend this to anyone using Unity who wants to try integrating a server!
I highly recommend this. Firebase is great, but the code structure you taught is a real pro-tip! I never knew architecture could be like this. I think this structure will be a huge help for my future projects as well.
This is truly the best Unity lecture on Inflearn~ It's so easy to understand, and I've learned so much!
