equivalent to addExternalMeshLoader for cameras?

[silex]

Hi,

Looking at the API, the SceneManager exposes 3 functions to add cameras to the scene. What I'd like to do is modify the behavior or the the default CameraSceneNode when certain keys are pressed (in this case, to have a camera looking from the side that can move up and down, and zoom in and out), so probably just it's OnEvent function. What's the best way to accomplish something like this? Is there a way to do this with the engine or must it be done externally?

Cheers,
Nick

sorry for the bump but i'll just rephrase my question:

what's the best way to customize camera behavior without modifying any source?

Make a regular ICameraSceneNode and manipulate it yourself each frame and with your event receiver.
