//store transform, (like opengl's glPushMatrix())
Matrix mat1 = graphics.Transform;
//transform into position
graphics.TranslateTransform(m_position.X, m_position.Y);
graphics.RotateTransform(m_angle/(float)Math.PI * 180.0f);
try
{
//draw body
graphics.DrawRectangle(new Pen(m_color), rect);
//draw line in the "forward direction"
graphics.DrawLine(new Pen(Color.Yellow), 1, 0, 1, 5);
}
catch(OverflowException exc)
{
//physics overflow :(
}
//restore transform
