C# moviendo el mouse de manera realista
Probé el método de cálculo del arco, resultó demasiado complejo y, al final, no parecía realista. Las líneas rectas parecen mucho más humanas, como sugiere JP en su comentario.
Esta es una función que escribí para calcular un movimiento lineal del mouse. Debería ser bastante autoexplicativo. GetCursorPosition() y SetCursorPosition(Point) son contenedores de las funciones de win32 GetCursorPos y SetCursorPos.
En cuanto a las matemáticas, técnicamente, esto se llama interpolación lineal de un segmento de línea.
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);
}
Convertí el WindMouse función mencionada anteriormente en C# y en realidad es bastante realista. Tenga en cuenta que esto es solo una muestra aproximada y no usa envoltorios para GetCursorPos y SetCursorPos . Usaré los envoltorios del Simulador de entrada de Windows.

Aquí hay algunos métodos escritos en SCAR. Convertirlos en C# no debería ser demasiado difícil, estos son bastante realistas.
