Exemplo n.º 1

Arquivo: body_member.cpp Projeto: Arnaud474/Warmux

void BodyMemberParticle::Refresh()
{
  m_time_left_to_live--;
  UpdatePosition();

  angle_rad += GetSpeedXY().Norm() * 20;
  angle_rad = fmod(angle_rad, 2 *PI);
  //FIXME what about negatives values ? what would happen ?
  if (m_time_left_to_live < 50)
    image->SetAlpha(m_time_left_to_live / 50.0);
  image->SetRotation_rad(angle_rad);
  image->Update();
}

Exemplo n.º 2

Arquivo: air_attack.cpp Projeto: yeKcim/warmux

void Plane::DropBomb()
{
  Obus * instance = new Obus(cfg);
  instance->SetXY(Point2i(GetX(), obus_dy));

  Point2d speed_vector = GetSpeedXY();

  int fx = RandomSync().GetInt(FORCE_X_MIN, FORCE_X_MAX);
  fx *= GetDirection();
  int fy = RandomSync().GetInt(FORCE_Y_MIN, FORCE_Y_MAX);

  speed_vector.SetValues(speed_vector.x + fx/(Double)30.0, speed_vector.y + fy/(Double)30.0);
  instance->SetSpeedXY(speed_vector);

  ObjectsList::GetRef().AddObject(instance);

  last_dropped_bomb = instance;
  nb_dropped_bombs++;

  if (nb_dropped_bombs == 1)
    Camera::GetInstance()->FollowObject(instance);
