C＃拖动鼠标

Question

我试图创建一个程序，当我点击左键单击它时拖动鼠标，而不是我将鼠标向下移动游戏，但它根本不会移动游戏。它将光标移动到游戏之外，但不会在游戏中移动。

    public static Point Position { get; set; }
    public Anti_Recoil()
    {
        InitializeComponent();
    }

    private void Anti_Recoil_Load(object sender, EventArgs e)
    {
        this.BackColor = Color.Wheat;
        this.TransparencyKey = Color.Wheat;
        this.TopMost = true;

        int initialStyle = GetWindowLong(this.Handle, -20);
        SetWindowLong(this.Handle, -20, initialStyle | 0x80000 | 0x20);



        PointConverter pc = new PointConverter();

        Point pt = new Point();

        pt = (Point)pc.ConvertFromString("765, 500");

        Cursor.Position = pt;
    }

    private void Anti_Recoil_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Z)
            Hide();
    }

            static int delta = 0;
            static int numberOfTextLinesToMove = 0;
            static int numberOfPixelsToMove = 0;
            public static bool GetWheelValues(Control FocusedControl, out int Delta, out int NumberOfTextLinesToMove, out int NumberOfPixelsToMove, int FontSize = 20)
            {
                try
                {
                    if (FocusedControl == null) throw new NullReferenceException("The FocusedControl can not bel null");
                    if (!FocusedControl.Focused) FocusedControl.Focus();
                    FocusedControl.MouseWheel += (object sender, MouseEventArgs e) =>
                    {
                        delta = e.Delta;
                        numberOfTextLinesToMove = e.Delta * SystemInformation.MouseWheelScrollLines / 120;
                        numberOfPixelsToMove = numberOfTextLinesToMove * FontSize;
                    };

                    Delta = delta;
                    NumberOfTextLinesToMove = numberOfTextLinesToMove;
                    NumberOfPixelsToMove = numberOfPixelsToMove;

                    return true;
                }
                catch
                {
                    Delta = 0;
                    NumberOfTextLinesToMove = 0;
                    NumberOfPixelsToMove = numberOfPixelsToMove;

                    return false;
                }
            }

            private class Win32
            {
                [DllImport("User32.Dll")]
                public static extern long SetCursorPos(int x, int y);

                [DllImport("User32.Dll")]
                public static extern bool ClientToScreen(IntPtr hWnd, ref POINT point);

                [StructLayout(LayoutKind.Sequential)]
                public struct POINT
                {
                    public int x;
                    public int y;
                }
            }
        }
    }
}

然后你需要检查鼠标的状态，

bool MouseLeftButton = Hector.Framework.Utils.Peripherals.Mouse.MouseButtonIsDown(1);

试试这个：

private void Form2_Load(object sender, EventArgs e)
{
    Hector.Framework.Utils.Peripherals.Mouse.MoveToPoint(300, 0); //Move the cursor to Top
}

//Then use timer to move the cursor
int a = 0;
private void timer1_Tick(object sender, EventArgs e)
{
    Hector.Framework.Utils.Peripherals.Mouse.MoveToPoint(300, a += 1);
}

if(MouseLeftButton)
{
   timer1.Start(); //timer is initialized
}
