Abstract scene.
|
|
This class provides the basic super class for all scenes. To render a
|
|
frame of the implemented scene the method "render" must be called. If
|
|
the scene is animated the method "advance_frame" can be overwritten. It
|
|
is called every 1/30sec (from the application-class).
|
|
For debugging purpose a method "set_text" is provided which modifies a
|
|
text stream that will be displayed in the main window.
