What I need to do is search all the scenes in a project for all objects that are referencing a specific script. I know you can search the current scene using the search bar in the Hierarchy view, but when a project has a couple dozen scenes and a thousand objects, that gets hard. Is there something I just can’t find that will do this for me?
Not that I know of. I was able to walk through all scenes in a project using an Editor script and the System.IO file and directory functionality (by searching for all “*.unity” files in the project and then using EditorApplication.OpenScene() to load them consecutively). Then you can process them in your script.
