Public Member Functions | |
| GameObject () | |
| GameObject (const GameObject &rhs) | |
| virtual | ~GameObject () |
| virtual void | update (float elapsed_time)=0 |
| This function is called once per frame and allows the object to update it's state. | |
| virtual void | draw (DrawingContext &context)=0 |
| The GameObject should draw itself onto the provided DrawingContext if this function is called. | |
| bool | is_valid () const |
| returns true if the object is not scheduled to be removed yet | |
| void | remove_me () |
| schedules this object to be removed at the end of the frame | |
| void | add_remove_listener (ObjectRemoveListener *listener) |
| registers a remove listener which will be called if the object gets removed/destroyed | |
| void | del_remove_listener (ObjectRemoveListener *listener) |
| unregisters a remove listener, so it will no longer be called if the object gets removed/destroyed | |
| const std::string & | get_name () const |
Protected Attributes | |

| virtual void GameObject::update | ( | float | elapsed_time | ) | [pure 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)
