Silverlight Game Design: (v) Object-oriented thinking shaping game objects

Legend has it that object-oriented development patterns were first created by lazy programmers. Development so far, people from the initial hot loyalty to discuss whether a certain language is enough object-oriented to now start a broader focus on object-oriented thinking rather than concrete content. Object-oriented thinking is actually not abstruse, it exists only for one purpose: Let the program development closer to our real world.

Remember the cat, the cat barking, the dog, the dog eating? Countless programmers like to use this similar scenario design as the best example of object-oriented. Yes, very vivid and image, but in practical use can you really do extrapolate?

Back to the game design, do we often feel that the game world is so close to our real world? The elves in the game are like we humans, more broadly, you can regard the Elves as any life in the game world. In the real world, "man" is a generic term for a guy like me, "people" can stand, can move, can fight, can be wounded, can die; in the game world, "Sprite" is a general term for all life bodies, "elves" can also stand (stand), can move (MoveTo), Can Fight (Attack), can be injured (injured), can die (Death).

Each "person" lives in their own "city", "City" has a road, there are bridges, mountains, water ... A wide variety of ground conditions form the façade structure of the whole city; elves "exist in their respective" scenes (Scene), each "scene" has a vivid background map (map) to show the beautiful scenery, the elves are laying the coordinate system (coordinates) of the "scene" In the free life. As long as they are happy, they can go to different "scenes" to visit friends or adventure. Therefore, the "scene" management of all its internal objects such as "elves", "Magic" and so on, as the host game elements of an important hub, it has extraordinary significance:
