@Override
public boolean keyDown (int keyCode) {
  if (keyCode == Keys.D) m_platform.setType(BodyType.DynamicBody);
  if (keyCode == Keys.S) m_platform.setType(BodyType.StaticBody);
  if (keyCode == Keys.K) {
    m_platform.setType(BodyType.KinematicBody);
    m_platform.setLinearVelocity(tmp.set(-m_speed, 0));
    m_platform.setAngularVelocity(0);
  }
