Question

How could I intercept a save scene action being run in Unity?

There is some code I would like to run in editor whenever a scene is saved. Is it possible for me to detect somehow when a scene is saved?

Unity already has a built-in event for doing exactly what you want: EditorSceneManager.sceneSaving

Usage:

EditorSceneManager.sceneSaving += OnSavingScene;

private void OnSavingScene(UnityEngine.SceneManagement.Scene scene, string path) {
    //do some stuff here
}
