Hi Gonzalo DÃaz,
Based on your description and the action script you provided with, I find a similar implementation below:
Animation.cs, the file includes the animation logic:
internal class Animation
{
/// <summary>
/// Initialization
/// </summary>
/// <param name="form">the animation form</param>
/// <param name="timeInterval">the ticket amount for each move</param>
public Animation(Form form, int timeInterval)
{
_hx = form.ClientRectangle.Width / 2 - 20;
_r = 300;
form.MouseMove += new MouseEventHandler(form_MouseMove);
_timer.Interval = timeInterval;
_timer.Tick += new EventHandler(_timer_Tick);
}
/// <summary>
/// Add a control , save its information and initiallize it
/// </summary>
/// <param name="ctrl"></param>
public void AddControl(Control ctrl)
{
ControlState ctrlState = new ControlState();
ctrlState.Control = ctrl;
ctrlState.StartLocation = ctrl.Location;
ctrlState.StartSize = ctrl.Size;
ctrlState.StartColor = ctrl.ForeColor;
//Stop moving when the mouse is on the control and change the size of the control to alert user.
ctrl.MouseEnter += new EventHandler(ctrl_MouseEnter);
ctrl.MouseLeave += new EventHandler(ctrl_MouseLeave);
this._controls.Add(ctrlState);
}
private void ctrl_MouseEnter(object sender, EventArgs e)
{
_stopped = true;
Control ctrl = sender as Control;
ctrl.Size = Size.Round(new SizeF(ctrl.Width * FONT_CHANGE_MOUSE_ON, ctrl.Height * FONT_CHANGE_MOUSE_ON));
ctrl.Font = new Font(ctrl.Font.FontFamily, ctrl.Height * FONT_BUTTON_WIDTH__RATE);
}
private void ctrl_MouseLeave(object sender, EventArgs e)
{
_stopped = false;
Control ctrl = sender as Control;
ctrl.Size = Size.Round(new SizeF(ctrl.Width / FONT_CHANGE_MOUSE_ON, ctrl.Height / FONT_CHANGE_MOUSE_ON));
ctrl.Font = new Font(ctrl.Font.FontFamily, ctrl.Height * FONT_BUTTON_WIDTH__RATE);
}
/// <summary>
/// Start the animation.
/// </summary>
public void Start()
{
float angleUnit = (float)(2 * Math.PI / _controls.Count);
float initAngle = 0.0f;
foreach (ControlState ctrl in _controls)
{
ctrl.StartAngle = initAngle;
initAngle += angleUnit;
}
_timer.Start();
}

{
return -(_mouseX - _hx)* 1.0f / num;
}
/// <summary>

private void Rotate(ControlState ctrlState)
{
if (_stopped == false)
{
//Calculate the moving distance
