class Program: Form
{
int x1;
int y1;
int x2;
int y2;
Button up = new Button();
Button start = new Button();
public Program()
{
Size=new Size(800,800);
x1 = 365;
y1 = 280;
x2 = 365;
y2 = 280;

/*Create Buttons*/


up.Text = "Up";
up.Click += new EventHandler(up _Click);
up.Location = new Point(340, 550);
up.Size = new Size(100, 40);

this.Controls.A dd(up);


start.Text = "Start/"+"\n"+"Pau se";
start.Click += new EventHandler(st art_Click);
start.Location = new Point(340, 600);
start.Size = new Size(100, 40);
this.Controls.A dd(start);

this.Paint += new PaintEventHandl er(myform_Paint );

}
void up_Click(object sender, EventArgs e)
{
AnimateUp();
}

void start_Click(obj ect sender, EventArgs e)
{
AnimateStart();
}

private void AnimateUp()
{

if (start.Text == "Assume")
start.Text = "Pause";

{
while (y2 > 24)
{

y2 = y2 - 10;
this.Invalidate ();
this.Refresh();
System.Threadin g.Thread.Sleep( 100);
}
x1 = x2;
y1 = y2;
MessageBox.Show ("Game Over!!", "End of the game", MessageBoxButto ns.OKCancel);
Application.Exi t();
}
}

private void AnimateStart()
{


if (start.Text == "Start/" + "\n" + "Pause")
start.Text = "Pause";

else if (start.Text == "Pause")
start.Text = "Assume";
}

private void myform_Paint( object sender,PaintEve ntArgs e)
{
Graphics g = e.Graphics;
Brush brush = new SolidBrush(Colo r.Black);
Pen pen = new Pen(brush, 4);
g.DrawRectangle (pen, 20, 20, 750, 500);

g.DrawLine(pen, x1, y1,x2, y2);
}


static void Main(string[] args)

Application.Run (new Program());
Application.Exi t();
