晕。。。。你的程序集是类库类型，你启动不了的。必须是windows应用程序或者控制台类型。[/quote] 网上查了一下，是需要单元测试调试吗，这个是我们比赛用的框架，今天看了一天，想问问怎么调试的，直接生成.dll文件调试太麻烦了 还不能解决问题，求教

[死磕unity]

为何前面的 PreProcess()实例化成功，但是下一个 DefineRotation()方法却失败了呢，而且，我把 DefineRotation()方法注释掉，下一个方法依然实例化失败，这个是比赛代码，给的是类库，不会调试.....只会控制台输出，有大大能解惑吗 没分了

this.Enemy.WheelOnStage = true;//出事代码 -》Enemy 为Null值，调试你的代码，看它的赋值过程。http://www.cnblogs.com/alexis/archive/2010/11/06/1870519.html

[正怒月神]

未将对象引用设置到对象的实例 那就是对象为Null了。断点调试就能解决的事情
