[转]XNA 3.1 转换到 XNA4.0 的备忘录

發(fā)布時間：2024/9/20 编程问答 36 豆豆
生活随笔 收集整理的這篇文章主要介紹了 [转]XNA 3.1 转换到 XNA4.0 的备忘录 小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
XNA 3.1 轉(zhuǎn)換到 XNA4.0 的備忘錄

xna3.1與4.0的區(qū)別不小，但也不是很大，在轉(zhuǎn)換一些項目時候下面的tip能給些幫助。原文地址是：http://blogs.msdn.com/b/shawnhar/archive/2011/01/04/xna-3-1-to-4-0-cheat-sheet.aspx?utm_source=twitterfeed&utm_medium=twitter
