C# 碰撞后移除障碍物？

我正在进行一场比赛（突破），我有一个问题

---

问题是，在障碍物被球击中后，我如何移除障碍物？ 当然，在那之后球必须能够穿过跑道（就像一般的突破赛）

下一个问题是，我可以在运行时模式下设置障碍吗

谢谢

您需要学习使用列表和正确使用类

例如：

public class GameObject{

  public GameObject(int x, int y, int width, int height){
     this.X = x;
     this.Y = y;
     this.Width = width;
     this.Height = height;
  }

  int X;
  int Y;
  int Width;
  int Height;

  public bool DetectCollision(bool Ball){
     //code to detect collision
  }
}

然后在你的主课上，你可以做这样的事情

List<GameObject> gameObjects = new List<GameObject>();
gameObjects.add(new GameObject(10,10,50,50));
gameObjects.add(new GameObject(20,10,20,50));
gameObjects.add(new GameObject(30,10,50,70));
gameObjects.add(new GameObject(40,10,90,50));

如果我们只知道球、板、板2等是什么东西，这会有帮助。问题是，在被球击中后，我如何才能移除障碍物？当然，球必须能够在那之后穿过跑道（就像一般的突破赛）

foreach (GameObject gameObject in gameObjects){
   if (gameObject.DetectCollision(ball)){
      //do something
   }
}
