碰撞后拆除障碍物？

Question

我正在制作游戏（Breakout），我有一个问题，

问题是我怎样才能在击球后消除障碍？ 当然，球之后必须能够通过赛道（如一般的突破游戏）

接下来的问题是，我可以在运行时模式中设置障碍吗？

由于

private void timer1_Tick(object sender, EventArgs e)

Answer 1

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
  }
}

然后在你的主课堂上，你可以做那样的事情。

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));

并检测碰撞：

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