What you will gain after the course

Basic knowledge for developing 2D tower defense games
Practical usage of reactive programming utilizing R3
Character summoning logic and combat logic
Implementation methods for game production elements such as BGM and SE

While it does not include online multiplayer functionality, it reproduces the flow of character summoning, combat AI, and tower destruction, allowing you to build a full-scale tower battle in a single-player environment.

Beyond just making a game that works, we will build a foundation that allows you to add features on your own after the course by implementing highly extensible component-oriented design and introducing reactive programming utilizing R3., chúng ta sẽ xây dựng một nền tảng vững chắc để bạn có thể tự mình thêm các tính năng mới sau khi kết thúc khóa học.함으로써 학습 후에도 스스로 기능을 추가할 수 있는 토대를 마련합니다.

From basics to applications of tower defense development in Unity 2D
Implementation of a battle system where you summon characters with a left-click, leading all the way to combat and tower destruction cho phép triệu hồi nhân vật bằng chuột trái, dẫn đến giao tranh và phá hủy tháp
Reactive programming with R3 for efficient and scalable code design
Implementation methods for audio and visual effects such as BGM and SE
Unity shortcuts and efficiency techniques trong Unity
Highly reusable component-oriented design

Through this course, you will complete your own tower battle game and significantly improve your Unity development skills.
We also offer support for questions, so you can take the course with peace of mind.

*In this course, assets from Goldmetal Studio are used.

*Note: This course is produced based on the original Japanese version.
The audio is primarily in Japanese, and you can switch to Korean automatic dubbing or Korean subtitles as needed.
However, due to the nature of automatic dubbing, the audio may sound unnatural in some sections.
Therefore, we recommend "Japanese Audio + Korean Subtitles" as the most stable way to watch.
