C++ (Cpp) Rotatex Beispiele

Beispiel #1

  void Rotate(const Angle alpha) {
    const auto sc = alpha.SinCos();
    const fixed sin = sc.first, cos = sc.second;
#ifdef FIXED_MATH
    long s = sin.as_glfixed();
    long c = cos.as_glfixed();
#else
    long s = sin * (1<<16);
    long c = cos * (1<<16);
#endif
    Rotatex(s, c);
  }
