C# 控制台应用程序 - gameloop / 多个对象

Posted 2023-03-10

【中文标题】C# 控制台应用程序 - gameloop / 多个对象

【英文标题】：C# console App - gameloop / multiple object

【发布时间】：2018-06-22 07:17:29

【问题描述】：

正如标题所说，我目前正在使用 c# 开发控制台游戏。问题是，我每次都无法制作一个有效的游戏循环......而且我有一个问题是“生成”多个对象，比如在这种情况下是子弹或敌人（我还是 c# 的新手，也是 stakoverflow ;P）

我希望你能帮助我让它工作！ :)

【问题讨论】：

寻求调试帮助的问题（“为什么这段代码不起作用？”）必须包括所需的行为、特定的问题或错误以及在问题本身中重现它所需的最短代码。没有明确问题陈述的问题对其他读者没有用处。见：minimal reproducible example

只是一点点帮助，这里有一个改进的PowerUp 类：class PowerUP private Random rnd = new Random(); public string WhichUP() => ":O^~".Substring(rnd.Next(4), 1); 。

【参考方案1】：

对于游戏循环，您可以创建 Unity3D 之类的东西，创建所有内容的函数启动（您可以在其中执行循环所需的操作），然后是更新函数“while(!end) Update();”

【讨论】：

您能否再澄清一下，因为我说我是新手，我目前在关注您时遇到问题。我到底应该怎么做？

【参考方案2】：

这个

   bool end  = false;
   static void Main(string[] args)

  //Things before the Loop
  //Instantiate player etc
  while(!end) Update();




   void Update()//Loop
  // When the game is finished End = true
