C#-如果语句继续

我想检查无人机[I]的位置是否在每架无人机[除我]的安全区域内基本上我不想检查无人机[I]。位置在无人机[I]内。安全区域。

也许我需要另一个循环什么的

我看到像这样的东西

if(i== ) continue; 

但是我能等于什么呢

代码：

对于我拥有的每一架无人机：
字符串ip（示例“192.168.1.10”
点位置（x，y）
点安全区
对于（int i=0；i您可以使用linq

public class Drone
{
    public int ID { get; set; }

    public Point Position { get; set; }
    public bool IsInsideSafearea(Point point)
    {
        throw new NotImplementedException();
    }
}

public class Class1
{
    public void DoSomething()
    {
        var drones = new Drone[]
        {
            new Drone() {ID = 0, Position = new Point(1, 2) },
            new Drone() {ID = 1, Position = new Point(3, 4) },
            new Drone() {ID = 2, Position = new Point(4, 2) },
        };

        var myDrone = drones[0];

        bool result = drones
            .Where(d => d.ID != myDrone.ID)
            .All(d => d.IsInsideSafearea(myDrone.Position));
    }
}

根据我对你的问题的理解，你基本上有一架无人机，并且该无人机有一个安全区域。现在你要检查一架无人机是否在另一架无人机的安全区域内

   ___________
  /           \
 /             \
/               --------`       
|                      /   
| Drone Y's Safe Area /___    
|                         `
--------------------------`

换句话说，您正在查看另一无人机的位置是否在无人机Y的安全区域内。因此，您需要查找点是否在多边形内。您可以创建以下类：

public class Drone {

  public Point Position { get; set; }

  public Point[] SafeArea { get; set; }

  public bool CheckIfDroneWithinMySafeArea(Drone drone) {
     return IsWithinPolygon( this.SafeArea, drone.Position );
  }

  public static bool IsWithinPolygon(Point[] poly, Point dronePosition) {

     bool isWithinPolygon = false;

     if( poly.Length < 3 ) {
        return isWithinPolygon;
     }

     var oldPoint = new
        Point( poly[ poly.Length - 1 ].X, poly[ poly.Length - 1 ].Y );

     Point p1, p2;
     for( int i = 0; i < poly.Length; i++ ) {

        var newPoint = new Point( poly[ i ].X, poly[ i ].Y );
        if( newPoint.X > oldPoint.X ) {
           p1 = oldPoint;
           p2 = newPoint;
        }
        else {
           p1 = newPoint;
           p2 = oldPoint;
        }

        if( ( newPoint.X < dronePosition.X ) == ( dronePosition.X <= oldPoint.X )
              && ( dronePosition.Y - ( long ) p1.Y ) * ( p2.X - p1.X )
              < ( p2.Y - ( long ) p1.Y ) * ( dronePosition.X - p1.X ) ) {
           isWithinPolygon = !isWithinPolygon;
        }


        oldPoint = newPoint;
     }


     return isWithinPolygon;
  }
}

点（位置）如何位于其他点（安全区域）内？听起来像是（intj=0；j，

然后你的

if

语句将是

if（i==j）继续；

。我想简化。安全区域不是一个点。它是4个点。+x-x-y+y@juharr这不总是真的吗？当i递增时，j也会递增。@ScumbagSteve不，这个想法是，内循环将遍历外循环每个值的所有索引，因此i=0，然后j=0到n，然后i=1，j=0到n等等开启。我如何知道它进入了哪个无人机的安全区域？问题是我认为这对n架无人机不起作用。你在与无人机进行比较[0].ID.安全区域是一个简单的正方形。我只想加上和减去一个常数来创建一个安全的正方形区域。对我来说似乎有很多代码。我只想做一些事情，比如如果它在安全区域内，我想发送一个移动命令，让进入安全区域的无人机留在安全区域之外。比如x-1，y

public class Drone {

  public Point Position { get; set; }

  public Point[] SafeArea { get; set; }

  public bool CheckIfDroneWithinMySafeArea(Drone drone) {
     return IsWithinPolygon( this.SafeArea, drone.Position );
  }

  public static bool IsWithinPolygon(Point[] poly, Point dronePosition) {

     bool isWithinPolygon = false;

     if( poly.Length < 3 ) {
        return isWithinPolygon;
     }

     var oldPoint = new
        Point( poly[ poly.Length - 1 ].X, poly[ poly.Length - 1 ].Y );

     Point p1, p2;
     for( int i = 0; i < poly.Length; i++ ) {

        var newPoint = new Point( poly[ i ].X, poly[ i ].Y );
        if( newPoint.X > oldPoint.X ) {
           p1 = oldPoint;
           p2 = newPoint;
        }
        else {
           p1 = newPoint;
           p2 = oldPoint;
        }

        if( ( newPoint.X < dronePosition.X ) == ( dronePosition.X <= oldPoint.X )
              && ( dronePosition.Y - ( long ) p1.Y ) * ( p2.X - p1.X )
              < ( p2.Y - ( long ) p1.Y ) * ( dronePosition.X - p1.X ) ) {
           isWithinPolygon = !isWithinPolygon;
        }


        oldPoint = newPoint;
     }


     return isWithinPolygon;
  }
}

var d1 = new Drone();
   // set d1's position and safe area

var drones = new List<Drone>();
// Add drones to above list

// Now check if any of the drones are within d1's safe area
var dronesWithinD1zSafeArea = drones.Where( x => d1.CheckIfDroneWithinMySafeArea( x ) ).ToList();

public class Drone {
   public System.Windows.Point Position { get; set; }
   public Rectangle SafeArea { get; set; }
   public bool CheckIfDroneWithinMySafeArea(Drone drone) {
   return this.SafeArea.Contains( drone.Position );
   }
}
