UnityPython is a plugin for Unity3D that provides support for running Python code in Unity.

Special thanks to the developers of IronPython who developed the open-source integration of Python and .NET, which this plugin uses.

Place the source of this project anywhere in the "Assets" folder. For convenience, you can use the latest .unitypackage release from the releases page to do this.

public class HelloWorld : MonoBehaviour
{
	void Start()
	{
		var engine = Python.CreateEngine();
		var scope = engine.CreateScope();

		string code = "str = 'Hello world!'";

		var source = engine.CreateScriptSourceFromString(code);
		source.Execute(scope);

		Debug.Log(scope.GetVariable<string>("str"));
	}
