Unity is one of the most popular game engines in the world, known for its flexibility and support for multiple programming languages.

What Language Does Unity Use?

Unity initially supported multiple languages, but today, C# is its primary programming language. It no longer supports JavaScript (UnityScript) or Boo, making C# the go-to language for developing everything from game logic to AI and physics.

Can You Use Languages Other Than C# in Unity?

By default, Unity only supports C#, but there are ways to integrate other languages:
✅ Python – While not natively supported, you can use Python in Unity through plugins like Unity-Py.
✅ C++ – You can integrate C++ code into Unity using Native Plugins.
✅ Visual Scripting (Bolt) – If you prefer node-based programming instead of writing code, Unity offers Bolt, a visual scripting system for creating games without coding.

Why Did Unity Choose C#?

✔️ Easy to Learn and Read – Compared to C++, C# is more beginner-friendly and easier to understand.
✔️ Powerful and Efficient Memory Management – While C++ is faster, C# offers garbage collection, making memory management smoother.
✔️ Seamless Integration with Unity – All major Unity systems, including physics, animation, networking, and AI, are optimized for C#.

Conclusion

If you’re planning to start game development with Unity, learning C# is the best choice. While other languages can be used in specific cases, C# remains the most efficient and officially supported option
