AGK

You always need to create one single TAgkApplication instance in your application. You can also derive your own application class from TAgkApplication if you wish. A typical bare-bone application will look like this: 

var
  App: TAgkApplication;
begin
  App := TAgkApplication.Create;
  App.Title := 'My Application'; // ...etc. set application options
  App.SetScene(TMyScene);
end.

where TMyScene is your TAgkScene descendant class that will contain your initial startup scene. 

Note that you do not free the App object. That is done automatically when the application shuts down.
