What is Unity?

Unity is a video game engine that is also used in many other industries. It powers 28 percent of the top 1,000 PC games and over 70 percent of the top-selling VR Steam experiences [1]. Unity offers a suite of tools for developers, including graphics, VR and AR capabilities, animation tools, and more. By offering resources to teach users about the platform's source code, Unity makes coding more accessible. 

What language does Unity use?

Unity uses C#, an open-source, object-oriented, and cross-platform programming language. You can also use other languages if they compile a compatible DLL file. When you write your code, Unity will default to the Visual Studio editor, but you can also select your preferred editor from the External Tools panel.

Game engines similar to Unity game engine

Unity and Unreal Engine are two of the most popular game development engines, but other options include Godot, Amazon for Games, and CRYENGINE. The game engine that you choose for your project will depend on what you want the final product to look like, how you want to distribute it, and your prior programming experience. 

Pros and cons of Unity vs. Unreal Engine

Unity and Unreal Engine are popular because they offer robust tools for developers to create video games and other applications. They have some differences that might affect which game engine you choose for your own project.

For one, Unity is more intuitive and easier to use for developers who don’t have a lot of prior experience. Both run on various platforms, but your chosen platform may determine whether you will use Unity or Unreal Engine. If you’re interested in making a game with advanced graphics, Unreal Engine offers more power despite the robust graphics Unity offers.

Lastly, if you’re monetizing your product, Unity and Unreal Engine have different costs. Unity offers seven plans to help you customize your licensing to the size of your product. Unreal has a simpler payment plan with less ability to customize, and it charges royalties.

What does Unity software do?

Unity helps designers and developers create games, prototypes, and simulations. You can use the software to create multiplatform games, grow your business, and for research and education. Unity also offers a variety of feature sets that can help you create different projects, such as augmented reality, cinematic studio, and virtual reality. 

Examples of Unity in different industries

Video games use Unity’s robust capabilities, but other industries are also beginning to turn to Unity, including government, architecture, automotive, manufacturing, and retail. 

In government, you can use Unity for complex simulation programs such as training platforms for the US Army. In 2022, Unity signed a deal with CACI International, a national defense contractor, to develop “Smart Human Machine Interfaces” [2]. In architecture, you can use Unity to plan buildings and visualize them in a 3D virtual reality space.
