XNA3.0到4.0的转换

http://blog.sina.com.cn/s/articlelist_1747721953_0_1.html

XNA4.0可以说是一个变化很大的版本了,许多类都被重构或者删除,转换的相关重点描述文章中,比较好的

是下面的URL地址: http://www.nelxon.com/blog/xna-3-1-to-xna-4-0-cheatsheet/ 不过这篇文章有些细节还是漏掉了一部分,如在XNA3.0中下面的代码显示选择存储设备的界面. public static StorageDevice XnaUserDevice { get { // Create if not created yet. if (xnaUserDevice == null) xnaUserDevice = StorageDevice.ShowStorageDeviceGuide(PlayerIndex.One); return xnaUserDevice; } // get } // XnaUserDevice 但是上面的代码在4.0下会提示StorageDevice没有BeginShowSelector函数,那么,如何改写这段代码呢?

看下面的代码. public static StorageDevice XnaUserDevice { get { if (xnaUserDevice == null) result = StorageDevice.BeginShowSelector(PlayerIndex.One, null,null); if (result.IsCompleted) xnaUserDevice = StorageDevice.EndShowSelector(result); return xnaUserDevice; } // get } // XnaUserDevice 在XNA4.0中,Game类的LoadGraphicsContent方法被LoadContent替代. 3.0 中GameTime属性ElapsedRealTime已被4.0的ElapsedGameTime取代 ========
