Unity C#

Trying to close a scene from the Hierarchy when a user clicks play in the editor. It returns True but the scene remains open.

[InitializeOnLoad]
class EditorClass : Editor{
    static EditorClass(){
        //user clicks play
        if (EditorApplication.isPlayingOrWillChangePlaymode) {
            //remove a scene
            Debug.Log(EditorSceneManager.CloseScene(EditorSceneManager.GetSceneByName(sceneName),false));
        }
    }
}

How to run it from MenuItem?

Would return false if the scene name didn't exist.

No, starts paused for testing.

Yeah, the function works that way so I guess it can't be done off the play button because there doesn't appear to be a way to intercept it soon enough or override it altogether. I'll post a solution if I find one, thanks for the help.

Only used for unloading the compiled scenes the game is running; not the editor Hierarchy.

Got it working.

Put a C# script in the Editor folder and paste this code. This will close all scenes currently loaded in the Hierarchy when the play button is clicked.

using UnityEditor;
using UnityEditor.SceneManagement;
using UnityEngine;
using UnityEngine.SceneManagement;
using System.Collections;
[InitializeOnLoad]
class Editor
{
	static Editor ()
	{
		EditorApplication.playmodeStateChanged += PlaymodeStateChanged;
	}
	private static void PlaymodeStateChanged(){
		if (!EditorApplication.isPlaying) {
			for (int i = 0; i < EditorSceneManager.sceneCount; i++) {
				Scene scene = EditorSceneManager.GetSceneAt (i);
				Debug.Log (scene.name);
				Debug.Log (EditorSceneManager.CloseScene (scene, false));
			}
		}
	}
}
