我认为你有提出了一个好的有效问题。但无论如何，对于这种思维错误，我总是首先尝试阅读文档（如果我使用特定技术（API），则更多）。



请查看 http://msdn.microsoft.com/ en-us / library / microsoft.xna.framework.game.update.aspx [ ^ ]



另请阅读有关Initialize和Draw的信息 - 我认为这很好在那里解释 - 以及调用方法的顺序（或间隔）（简而言之：不要指望在初始化阶段调用更新的beeing）。

I think you have formulated a good and valid question. But anyway, for this kind of "mind bugs" I'd always try to read the docu first (even more if I use a specific technology (API)).

so have a look at http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.game.update.aspx[^]

Read also about Initialize and Draw - I think it's well explained there - and the sequence (or interval) the methods get called (in short: don't count on Updated beeing called during initialization phase).
