I know that using panels isn't a good way for animantion. Please, tell me. I'm try to code a physical model for ball (Panel). But it doesn't work.

float a = 0.005f;

float v0 = 0.001f;

float deltaT;

float v=0.1f;

Stopwatch MyStopWatch;


public void StartGoingDown(Panel MyPanel, Form MyForm)

{

MyStopWatch = new Stopwatch();

MyStopWatch.Start();

System.Threading.Thread.Sleep(20);


//while (MyBall.Top < MyPanel.Height-90)

while(Math.Abs(v)>0 && Math.Abs(v0)>0)

{

deltaT = MyStopWatch.ElapsedMilliseconds;

v = v0 + a * deltaT/1000;

MyBall.Top += (int)(v * deltaT);

DrawBall();



if (MyBall.Top >= MyPanel.Height - 90)

{


MyBall.Top = MyPanel.Height - 91;

MyStopWatch.Reset();

MyStopWatch.Start();

v0 = -v;

v = 0;

//MyBall.Top -= 100;

}



System.Threading.Thread.Sleep(20);

}

DrawBall();


}
