XNA3到4的转换
XNA3.0到4.0的轉(zhuǎn)換
http://blog.sina.com.cn/s/articlelist_1747721953_0_1.htmlXNA4.0可以說是一個(gè)變化很大的版本了,許多類都被重構(gòu)或者刪除,轉(zhuǎn)換的相關(guān)重點(diǎn)描述文章中,比較好的
是下面的URL地址:
http://www.nelxon.com/blog/xna-3-1-to-xna-4-0-cheatsheet/
?
不過這篇文章有些細(xì)節(jié)還是漏掉了一部分,如在XNA3.0中下面的代碼顯示選擇存儲設(shè)備的界面.
public static StorageDevice XnaUserDevice
? {
? ?get
? ?{
? ? // Create if not created yet.
? ? if (xnaUserDevice == null)
? ? ?xnaUserDevice =
? ? ? ? ? ? ? ? ? ? ? ? StorageDevice.ShowStorageDeviceGuide(PlayerIndex.One);
? ? return xnaUserDevice;
? ?} // get
? } // XnaUserDevice
?
但是上面的代碼在4.0下會提示StorageDevice沒有BeginShowSelector函數(shù),那么,如何改寫這段代碼呢?
看下面的代碼.
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類的LoadGraphicsContent方法被LoadContent替代.
?3.0 中GameTime屬性ElapsedRealTime已被4.0的ElapsedGameTime取代

xna3.1與4.0的區(qū)別不小，但也不是很大，在轉(zhuǎn)換一些項(xiàng)目時(shí)候下面的tip能給些幫助。原文地址是：
