c# - 编写游戏，代码执行是随机的

Question

大家好，我只是 VS2010 中 C# 的初学者，学习它的原因是为了能够在游戏编程中发展，我得到了这个程序的源代码并向其中添加了很多东西。这是控制台应用程序源。

************************************************", heroHitPoints, monsterHitPoints);

            Console.Write(@"

该程序应该要求您选择一个选项，并且在您选择后执行它，怪物应该无论如何都会攻击。我创建了 3 个方法并调用了它们。我的问题是，以 IF 语句开头并在 while 之前结束的部分有时运行有时不运行，就像它完全随机一样，我认为这与怪物的命中率有关，但事实并非如此，感谢帮助。 VS2010 没有给我任何错误，而且英雄每次都会攻击，即使我对它们都使用相同的方式。

好的。我已经试过了，它工作正常，但是当怪物未命中时你不打印任何东西，这就是随机失败的意思吗？要纠正它，只需将 else 附加到条件:

hitchance = rand.Next(0, 100);
if (hitchance > 30)
{
    attackdamage = CH.GetMonsterDamage(rand);
    Console.WriteLine("The Monster Attacks!");
    if (battlechoice == "d" || battlechoice == "D")
    { //this is so that defend has some sort of benefit
        attackdamage /= 2;
    }
    heroHitPoints -= attackdamage;//subtract the damage
    Console.WriteLine("The Hero loses {0}hp", attackdamage);
}
else
{
    Console.WriteLine("The monster misses!");
}
