Statemachine
weil Standard nicht genug war
Was ist eine Statemachine
Tobias Hartmann
- Programmiermodell mit "Zuständen" (States)
- definierte Übergänge zw. Zuständen (Transitions)
- Aktionen (Actions/Events) abhängig vom Zustand
INAKTIV
SUCHEN
ANGRIFF
Wenn Abstand d. Spielfigur </> Sichtweite
Wenn Abstand d. Spielfigur </> Angriffsreichweite
Zustände einer computergesteuerten Spielfigur
Abbilden der Zustände durch gekapselteten Code (Klassen/Module) -> Struktur
Alexa hat eine eigene Statemachine. Warum nicht diese nutzen?
Tobias Hartmann
| Vorteile | Nachteile |
|---|---|
| Zustand wird automatisch in Session gespeichert | Debugging |
| Zustand kann persistiert werden (DynamoDB) | Läuft nur im Alexa SDK |
| Debugging nur mit erhöhtem Setup-Aufwand |
Was macht unsere Statemachine anders?
Tobias Hartmann
| Vorteile | Nachteile |
|---|---|
| keine Abhängigkeiten | Datenpersistenz |
| testbar | |
| Wiederverwendbarkeit | |
| Debugging |
