Detailed Description

The Scene class.

This class is the base class for all scenes. Rendering is supposed to be done by the scenes. Only one scene can be active at a time. There is a helper stack system for managing the scenes. See the Application class for more information.

Member Function Documentation

frame()

virtual void psyqo::Scene::frame ( )

inlinevirtual

Renders a frame.

This method will be called when the scene is active, every time a new frame is to be rendered.

start()

virtual void psyqo::Scene::start ( StartReason  reason )

inlinevirtual

Starts the scene.

This method will be called when the scene is started. It is meant to set the environment in a suitable manner. A scene starts when it becomes the active scene, either when being pushed or when the previous scene is popped. The argument will indicate whether the scene is started because it just got pushed, or because another one is getting popped.

Parameters

reason

The reason why the scene is started. Create or Resume.

teardown()

virtual void psyqo::Scene::teardown ( TearDownReason  reason )

inlinevirtual

Tears down the scene.

This method will be called when the scene is no longer the active scene. It is meant to clean up the environment, basically reversing the effects of start. The argument will indicate whether the scene is being popped, or if another scene is pushed on the stack.

Parameters

reason

The reason why the scene is being torn down. DESTROY or PAUSE.
