Can You Use JavaScript in Unity?

Practically no. UnityScript (a Unity created JavaScript variant) used to be an option but is now deprecated. The recommendation is to use C# for all Unity scripting as it is natively supported.

Comparison Table – JavaScript, UnityScript, and C# for Unity

Factor	JavaScript	UnityScript	C#
Language Origin	Developed by Netscape, standardized as ECMAScript	Inspired by JavaScript, specific to Unity	Developed by Microsoft, part of .NET Framework
Syntax	Based on ECMAScript standard	Similar to JavaScript but with some differences	Similar to Java and C++ with some unique features
Language Support	Widely supported in web browsers and server-side applications	Supported only in Unity (deprecated)	Supported in Unity, .NET applications, and various platforms
Performance	Varies depending on the platform and use case	Optimized for Unity but not as performant as C#	High performance, optimized for Unity
Libraries & Resources	Extensive libraries, frameworks, and resources	Limited to Unity-specific resources and functionality	Rich libraries, resources, and Unity-specific features
Learning Curve	Moderate, depending on prior programming knowledge	Moderate, especially for developers familiar with JavaScript	Moderate, familiarity with C++ or Java can be helpful
Compatibility	Compatible with various platforms and technologies	Compatible with Unity versions up to 2017 (deprecated)	Native support and compatibility with Unity features and updates
Community	Large and active community	Limited community, no longer officially supported by Unity	Large and active Unity community, extensive support

This table compares JavaScript, UnityScript, and C#, highlighting differences in language origin, syntax, support, performance, available libraries and resources, learning curve, compatibility, and community involvement. It is important to note that UnityScript has been deprecated and is no longer recommended for use in Unity projects. C# is the best choice for Unity development due to its native support, performance, and extensive resources.

What can you do with C# in Unity?

C# is a versatile and powerful programming language that allows you to accomplish a wide range of tasks in Unity. Here are some of the primary things you can do using C# in Unity:

1. Game logic and mechanics: Implement the core mechanics and rules of your game, such as character movement, enemy AI, win/lose conditions, and more.
2. User Interface (UI): Create dynamic and interactive UI elements, such as menus, HUDs, health bars, and score displays.
3. Physics: Utilize Unity’s built-in physics engine to create realistic object interactions, such as collisions, triggers, and forces.
4. Animation: Control animations and transitions, including character animations, object movements, and cutscenes.
5. Input handling: Capture and respond to player input, such as keyboard, mouse, touch, or controller input.
6. Audio: Manage audio sources, sound effects, and background music to enhance the game’s atmosphere and experience.
7. Custom shaders: Write custom shaders using C# to create unique visual effects and rendering techniques.
8. Networking: Implement multiplayer functionality, including real-time communication, player synchronization, and lobby systems.
9. Procedural generation: Create procedurally generated content, such as levels, terrain, or objects, to add variety and replayability to your game.
10. Save and load systems: Implement systems to save and load game progress, allowing players to continue their game from where they left off.
11. Asset management: Load, unload, and manage assets, such as textures, models, and prefabs, to optimize performance and memory usage.
12. Integration with third-party APIs: Connect to third-party APIs or services, such as analytics, leaderboards, or social media platforms, to extend your game’s functionality.

C# in Unity provides comprehensive tools and features to help you create engaging and immersive games, from simple 2D projects to complex 3D experiences. With its strong Unity engine integration and powerful capabilities, C# is the recommended language for Unity development.
