Acces a script in the editor folder

[system]

Say for instance I need to access a function that is in a class in the editor folder like this:

using UnityEngine;
namespace MyNamepace //in Editor folder
{
	public class myClass
	{
		public int Add(int int1, int int2)
		{
			return int1 + int2;
		}
	}
}

script outside of editor folder:

using UnityEngine;
using MyNamespace;
public class Test : MonoBehaviour
{
	public void Awake()
	{
		int1 = 2;
		int2 = 2;
		int result = myClass.Add(int1, int2);
		print(result.ToString());
	}
}

This gives a ‘CS0246: The type or namespace name `MyNamespace’ could not be found’ but it works when MyNamespace is outside of the Editor folder, note that this is just an example script because I dont want to post a 10 line and a 600 line script here. Any ideas?

The editor files are compiled last and with a reference to everything else - however the non-editor files do not have a reference to the editor code which is in a separate (and unreferenced) assembly.

So you can’t do that. Whatever needs to be referenced from both needs to be outside the Editor folder.

This is possible with reflection. It obviously breaks encapsulation but I have required it for a resource manager as static constructors in the editor don’t get re-ran on return from play mode.

System.Reflection.Assembly editorAssembly = System.AppDomain.CurrentDomain.GetAssemblies().First( a => a.FullName.StartsWith( "Assembly-CSharp-Editor," ) ); // ',' included to ignore  Assembly-CSharp-Editor-FirstPass
Type utilityType = editorAssembly.GetTypes().FirstOrDefault( t => t.FullName.Contains( "ResManEditorUtility" ) );
utilityType.GetMethod( "InitialiseResMan", System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Static ).Invoke( obj: null, parameters: null );
