Is there some kind of diagram or something that shows the existing script classes that can be inherited from etc?
If you use nFringe or WOTGreal to do your editing, they have a class tree that you can use. Other than that, there is the Actor section of the content browser inside the editor.
or you can use UnCodeX (install the latest stable build, and then download the latest development build). Remember, uncodex is more than just a tool to create HTML documentation.
Awesome, thanks everyone.
