How to Move Mouse Cursor Using C#

How to move mouse cursor using C#?

Take a look at the Cursor.Position Property. It should get you started.

private void MoveCursor()
{
   // Set the Current cursor, move the cursor's Position,
   // and set its clipping rectangle to the form. 

   this.Cursor = new Cursor(Cursor.Current.Handle);
   Cursor.Position = new Point(Cursor.Position.X - 50, Cursor.Position.Y - 50);
   Cursor.Clip = new Rectangle(this.Location, this.Size);
}

How to move mouse cursor using C# using while infinite loop?

Ultimately, the answer here is: "don't".

Windows forms are based on a message pump. If you have an event-handler from one message (like "click") that loops forever, it will never get around to processing other messages (like "draw"), so: your app is now unresponsive.

Instead of an infinite loop: use a Timer, and move the position in the callback. In this case, a System.Windows.Forms.Timer would be most appropriate.

How to move mouse cursor with joystick?

You are using

float h = horizontalSpeed * Input.GetAxis("Horizontal") * Time.deltaTime;
float v = verticalSpeed * Input.GetAxis("Vertical") * Time.deltaTime;
GUI.DrawTexture(new Rect(h, Screen.height - v, cursorWidth, cursorHeight), cursorImage);

h and v will always have very tiny values since multiplied by Time.deltaTime and Input.GetAxis afaik returns usually values between 0 and 1.

These values don't represent an actual cursor position but rather are the change of the position relative to the last frame.

Your cursor will be stuck somewhere in the top-left corner.

Instead you should store the current position and add your values as change to it like

private Vector2 cursorPosition;

private void Start()
{
    Cursor.visible = false;

    // optional place it in the center on start
    cursorPosition = new Vector2(Screen.width/2f, Screen.height/2f);
}

private void OnGUI()
{
    // these are not actual positions but the change between last frame and now
    float h = horizontalSpeed * Input.GetAxis("Horizontal") * Time.deltaTime;
    float v = verticalSpeed * Input.GetAxis("Vertical") * Time.deltaTime;

    // add the changes to the actual cursor position
    cursorPosition.x += h;
    cursorPosition.y += v;

    GUI.DrawTexture(new Rect(cursorPosition.x, Screen.height - cursorPosition.y, cursorWidth, cursorHeight), cursorImage);
}

Also note that horizontalSpeed and verticalSpeed are in Pixels / Seconds and you probably want some values bigger then 2 ;)

I used 200 and the Up, Down, Left & Right keys.

C# moving the mouse around realistically

I tried the arc calculation method, turned out to be far to complex and, in the end, it didn't look realistic. Straight lines look much more human, as JP suggests in his comment.

This is a function I wrote to calculate a linear mouse movement. Should be pretty self-explanatory. GetCursorPosition() and SetCursorPosition(Point) are wrappers around the win32 functions GetCursorPos and SetCursorPos.

As far as the math goes - technically, this is called Linear Interpolation of a line segment.

public void LinearSmoothMove(Point newPosition, int steps) {
    Point start = GetCursorPosition();
    PointF iterPoint = start;

    // Find the slope of the line segment defined by start and newPosition
    PointF slope = new PointF(newPosition.X - start.X, newPosition.Y - start.Y);

    // Divide by the number of steps
    slope.X = slope.X / steps;
    slope.Y = slope.Y / steps;

    // Move the mouse to each iterative point.
    for (int i = 0; i < steps; i++)
    {
        iterPoint = new PointF(iterPoint.X + slope.X, iterPoint.Y + slope.Y);
        SetCursorPosition(Point.Round(iterPoint));
        Thread.Sleep(MouseEventDelayMS);
    }

    // Move the mouse to the final destination.
    SetCursorPosition(newPosition);
}
