| void Spotlight::update | ( | float | elapsed_time | ) | [virtual] |
This function is called once per frame and allows the object to update it's state.
The elapsed_time is the time since the last frame in seconds and should be the base for all timed calculations (don't use SDL_GetTicks directly as this will fail in pause mode)

| void Spotlight::draw | ( | DrawingContext & | context | ) | [virtual] |
