游戏开发中的多态性？ [英] Polymorphism in Game Development?

问题描述

当您使用c＃或类似方法创建游戏时，使用与类相关的多态性是一种标准吗？



此消息中上传了一个多态的示例。



谢谢！

When you create a game in c# or similiar, is it a standard to use polymorphism in relation to classes?

A example of polymorphism is uploaded in this message.

Thanks!

推荐答案

我实际上看不到任何附加此消息。



无论如何，是的，使用多态性是很常见的。大多数游戏对象都会参与更新/绘制逻辑，因此他们可能会实现虚拟更新和绘制方法，不同类别（如敌人，玩家角色等）恰好有所不同。



当然，真正的细节会因用于编写游戏的框架而发生很大变化。例如，当我在WPF中创建游戏时，渲染大部分时间是使用WPF数据模板完成的，因此我不需要在类的任何虚拟方法上进行绘制。我还能够将动画与对象本身分开，因此敌人对象不需要动画的虚拟方法。然而，动画本身是多态的。



请参阅这些文章以获得一个想法：

Shoot'em Up .NET [ ^ ]

编写多人游戏（在WPF中） [ ^ ]



我在这篇文章中甚至用游戏来解释OOP：

面向对象编程简介（OOP） [ ^ ]

它实际上显示了w使用多态（虚拟方法）使游戏有效是一个好主意。

I actually don't see anything "attached" to this message.

In any case, yes, it is very common to use Polymorphism. Most game objects will participate in the Update/Draw logic, so they will probably have a virtual Update and Draw method implemented, which happens to be different by different classes (like enemies, the player character etc).

Of course the real details change a lot by the framework used to write the game. When I create games in WPF, for example, the rendering is most of the time done using WPF data-templates, so I don't need any virtual method on the class for the drawing. I am also able to separate animations from the objects themselves, so the Enemy objects don't need a virtual method for the animation. Yet, the animations themselves are polymorphic.

See these articles to have an idea:
Shoot'em Up .NET[^]
Writing a Multiplayer Game (in WPF)[^]

And I even used games to explain OOP in this article:
Introduction to Object Oriented Programming (OOP)[^]
It actually shows why it is a good idea to use Polymorphism (virtual methods) to make the game work.
