Zdarzenia

Zdarzenia i klawisze: sterujemy duszkiem - Informatyka - klasa 5 (bloczki)

**Zdarzenie** to coś, co dzieje się w czasie działania programu: ktoś wcisnął klawisz, poruszył myszą, duszek dotknął krawędzi. Pętla **zawsze powtarzaj** w każdym obiegu sprawdza warunki **jeśli** i reaguje na zdarzenia. Tu każda strzałka ustawia kierunek i przesuwa duszka. Kliknij planszę, a potem steruj strzałkami. Pisak rysuje drogę.
