Unity3d - Load a specific scene on play mode

I made this simple script that loads the scene at index 0 in the build settings when you push Play. I hope someone find it useful.

It detects when the play button is push and load the scene. Then, everything comes back to normal.

Oh! And it automatically executes itself after opening Unity and after compile scripts, so never mind about execute it. Simply put it on a Editor folder and it works.

#if UNITY_EDITOR
using UnityEditor;
using UnityEditor.SceneManagement;

[InitializeOnLoadAttribute]
public static class DefaultSceneLoader
{
    static DefaultSceneLoader(){
        EditorApplication.playModeStateChanged += LoadDefaultScene;
    }

    static void LoadDefaultScene(PlayModeStateChange state){
        if (state == PlayModeStateChange.ExitingEditMode) {
            EditorSceneManager.SaveCurrentModifiedScenesIfUserWantsTo ();
        }

        if (state == PlayModeStateChange.EnteredPlayMode) {
            EditorSceneManager.LoadScene (0);
        }
    }
}
#endif

The easiest way is to set your 0th scene as the default play mode scene:

[InitializeOnLoad]
public class EditorInit
{
    static EditorInit()
    {
        var pathOfFirstScene = EditorBuildSettings.scenes[0].path;
        var sceneAsset = AssetDatabase.LoadAssetAtPath<SceneAsset>(pathOfFirstScene);
        EditorSceneManager.playModeStartScene = sceneAsset;
        Debug.Log(pathOfFirstScene + " was set as default play mode scene");
    }
}
