我不敢相信我被困在这个上面，目前我的玩家代码允许玩家四处走动，甚至允许玩家在按下Ctrl和K按钮时自杀。现在我的问题是，当玩家自杀时，它会在角落画一串文字，并带有一个有趣的陈述。但我不希望这是唯一的一个，我希望它根据你自杀，我不知道究竟如何把这个变成运动，我的继承人播放器代码3个不同的语句之间交替：如何在XNA中调用一个随机字符串？

这里是我希望它在我的绘制方法中交替的地方。

}
随机工作究竟如何？我将如何在这里实现它？编辑：我试着实现你说的，我得到一个错误'不能隐式转换'字符串'到'字符串[]'它奇怪的，我认为它在哪里我试图把这个，在哪里它会去吗？
EDIT2：对不起，错字就我而言，我只注意到了“[]”的第一个字符串测试后..
决赛：与您的代码后酝酿好了，我终于得到它的工作对我的期望，为了连续性，我还必须修改一些变量。
我在构造函数中加入这样的：
String suicideStr;
public bool suicide;
这到LoadContent（）;方法：
suicideStr = strs[random.Next(strs.Length)];
将此bool添加到Update（）中;方法：
if (suicide == true)
{
suicided();
}
然后我在变量增加了它，并添加到了自杀的按钮：
if (keyState.IsKeyDown(Keys.LeftControl) && keyState.IsKeyDown(Keys.K))
{
isplayeralive = false;
isplayerdead = true;
bloodspatter = true;
suicide = true;
}
并添加到点击重生变量：
if (isplayeralive == false && LMBpressed == true)
{
isplayeralive = true;
isplayerdead = false;
suicide = false;
suicideStr = strs[random.Next(strs.Length)];
}
然后如果自杀变量等于真，我就完成了绘图工作。
什么我认为我所做的是告诉游戏画出文本，如果玩家自杀，每次玩家点击/自杀，然后更新字符串。这是正确的想法吗？
我已经修复了你的代码，以便每次你需要一个随机数时你不会创建一个'Random'的新实例，因为这是一个*巨大的*不 - 不！但是，您的代码仍然被破坏 - 每帧显示不同的随机消息！ – 2013-04-10 06:15:28
@AndrewRussell：谢谢您的通知。我会再次修改它。 – 2013-04-10 06:20:40
是的，我可以同意这一点，消息发展得很快，我以为我在矩阵中，当我回家时我会试试这个，谢谢！ – 2013-04-10 16:58:40
