ImplementatioN

• Blender was selected as the engine. It is actually a 3d modelling and animation and rendering tool, which very exceptionally includes a real-time engine for interactive 3d.
• The target was a high-level event (/Action?) abstraction to bind controls to low-level actions (what the engine is told to do)
• The Class Library

The Class Library

make UMLs? of this!:

class Event:
    def __init__(self, scene, type)
    def act(self, mover=None):
    def start(self):
        self.scene.act_events.append(self)
    def stop(self):
        self.scene.act_events.remove(self)
