How to Develop 2D Games Using R and Unity2D
If you are interested in developing 2D games, you might have heard of Unity2D, a powerful and popular engine that allows you to create stunning games for various platforms. But did you know that you can also use R, a programming language and environment for statistical computing and graphics, to enhance your game development process? In this article, we will show you how to use R and Unity2D together to create amazing 2D games.
What is R?
R is a free and open-source software that is widely used for data analysis, visualization, and machine learning. It has a rich set of packages and libraries that provide various functions and tools for working with data. R can also be used to create interactive graphics and applications using frameworks such as Shiny and R Markdown.
What is Unity2D?
Unity2D is a feature of Unity, a real-time development platform that enables you to create 3D, 2D, VR and AR games and applications. Unity2D provides a set of tools and components that make it easy to create 2D games with sprites, animations, physics, collisions, sound, UI, and more. You can also use C#, a general-purpose programming language, to write scripts that control the logic and behavior of your game objects.
How to Use R and Unity2D Together?
One way to use R and Unity2D together is to use R.NET, a library that allows you to access R from .NET applications. You can use R.NET to call R functions and objects from C# scripts in Unity. This way, you can leverage the power of R for data analysis, visualization, and machine learning in your game development process.
Here are some steps to use R.NET in Unity:
Download and install R from the official website: https://www.r-project.org/
Download and install Visual Studio Community Edition from the official website: https://visualstudio.microsoft.com/
Create a new C# class library project in Visual Studio and add the R.NET package using NuGet: https://www.nuget.org/packages/R.NET.Community/
Write your C# code that uses R.NET to access R functions and objects. For example:
public class RTest
public static void Main(string args)
// Set the path to the R engine
REngine.SetEnvironmentVariables(@\"C:\\Program Files\\R\\R-4.1.1\\bin\\x64\", @\"C:\\Program Files\\R\\R-4.1.1\");
// Create an instance of the R engine
REngine engine = REngine.GetInstance();
// Evaluate an R expression
var result = engine.Evaluate(\"rnorm(10)\").AsNumeric();
// Print the result
Console.WriteLine(\"Random numbers from R:\");
foreach (var num in result)
// Dispose the engine
Build your project and copy the output DLL file (RUnity.dll) and its dependencies (RDotNet.dll and RDotNet.NativeLibrary.dll) to the Assets folder of your Unity project.
Create a new C# script in Unity and attach it to a game object. In the script, add a reference to the RUnity namespace and call the Main method of the RTest class. For example:
public class TestScript : MonoBehaviour
// Start is called before the first frame update
// Call the Main method of the RTest class
// Update is called once per frame
Run your game in Unity and check the console output. You should see 10 random numbers generated by R.
