Inspector GUI - Opening a file?

Hey there,

I have like a custom inspector in where I use my own kind of scripting language...I don't know if you'd even call it that, but in any case my inspector ends up looking like this:



My plan with this was to go into Notepad++ and create a custom auto completion thing or whatever so that I can color my language.

What I want to do now, though, is to create a button after the 'load script' button underneath the save button.

I know that once I have the path to the file I can use this little snippet:

Code (CSharp):

1. List<string> eventCommandsFromFile = File.ReadAllLines(filePathAndName).ToList();

I can also see that you have to use this:

https://docs.unity3d.com/ScriptReference/EditorUtility.OpenFilePanel.html

I've got my custom inspector script all set up, I know how to create the button, but I'm not sure how to implement this properly:

Code (CSharp):

1. if (GUILayout.Button ("Add From Script", GUILayout.Width (300f), GUILayout.MinWidth (0f))) {
2.    if (EditorUtility.DisplayDialog ("Add From Script", "This will overwrite all Ecmds on the current page. Are you sure?", "Yes", "Cancel")) {
3.           //Not sure what I would put here...
4.     }
5. }

I'm wondering if I put in like....

Code (CSharp):

1. string fileAndPath = EditorUtility.OpenFilePanel("Select Event File", "", "event");

I don't know why but last time I did that it had the open file panel open and I couldn't close it.
