Editor Window with settings and Asset Creation

Question

Hi There

Is it possible to create an editor window that has some persistent settings that can then be used to create a new asset or modify an existing one?

My use case is that I am autogenerating some items in my RPG and previously I was doing this externally in a little c# console app that created a csv file and then I was using an editor menu script to read the csv and create and modify a List of item definitions on the selected unity object (containing the appropriate script). I'd rather make the items within unity as part of of an editor window and have some settings that I can modify that change the way in which the items are created. I then want that item setting data to persist between sessions.

I'm also toying with the EditorWindow creating a custom asset - maybe some XML - that I could then load at runtime.

I've been trying to use ScriptableObjects for my item generated data but I can't get the UI to autogenerate for these scripts, I also don't know whether they will persist (but I could probably write some XML out and read it back in). The added complexity here is that I need an array of objects, each object containing parameters for a set of objects I want to generate at the push of a button!

Presumably this kind of scenario can easily be solved and has to be solved for many extensions to the editor?

Thanks in advance! H

So my solution to this was to:

Create a class subclassing SciptableObject for the editor data
Create an EditorWindow subclassing EditorWindow
In the static Init() method to Get/Create the window I checked for the existence of my EditorData and load if present or create if not
Used EditorGUI.Popups to display the elements I could edit from the various Lists within my EditorData
Displayed GUI below each Popup for the content of the selected item in the popup
Continued with more EditorGUI.Popups and GUI below for detail (master/detail really)
Buttons to add/edit/rename bits of EditorData
A button to create the in-game asset, also a subclassed ScriptableObject

The above took me the best part of a day and I ended up with the image posted at the end.

However, I found this very painful to make, taking a day, and having worked with ScriptableObject subclasses I then elected to do the following:

For the same EditorData subclass of ScriptableObject, I created an Editor subclass
In OnInspectorGUI() I called the base method...
...I then added GUI for a button to generate the in-game data
I Added a menu item to create the EditorData
I deleted the original editor

This gives me List editing just as I would get for any serialisable object as a public member of a script attached to a GameObject within Unity. It is perhaps not as elegant as the master detail scenario, but it took me about an hour or so to get it working and I wasn't somewhat confused about how to style things.

I think for more advanced editing, that the EditorWindow might have some benefit, but the Editor solution is quicker to code and provides a very usable view of the data.

I hope this information helps someone else who wishes to have EditorData and generate real game data from that.
