Użycie

1. Zaznacz obiekt w Blenderze
2. Przejdź na panel "Scripting"
3. Wklej kod
4. Uruchom "Run Script", żeby przypisać skrypt animacji do obiektu
5. Można przetestować działanie animacji na panelu Layout > playback

Ta konkretna animacja trwa 100 klatek
1-50: ruch po osi Z do góry (aż współrzędna Z=5.0) i jednoczesny obrót wokół osi Z o 180 stopni
50-100: ruch w dół i dalsze rotacja do wykonania pełnego obrotu

This solution works in 3x version.
