Spiel – StarWars
Abbildung:
Beschreibung:
1) Schacht
2) Punkte
3) Leben / Energie
4) Flugzeug / Kampfschiff
5) Fadenkreuz
Die Zielkoordinaten (Treffen) sind im:
// Hit
if(X_pos<=-18 && X_pos>=-20 && Y_pos<=-8 && Y_pos>=-10)
definiert, und können beliebig (je nach Geduld / Ausdauergrad ) geändert werden.
Ob die Änderung der Zielkoordinaten Sinn macht: (z.B.)
if(X_pos<=-14 && X_pos>=-24 && Y_pos<=-8 && Y_pos>=-18){
wird dem Programmierer überlassen.
Navigation:
Schuss – S Button (Im IDE Simulator: Enter)
Bewegen – L, R, U, D Buttons (Im IDE Simulator: Pfeiltasten)
Aufgabe:
Die Abgefeuerte „Rakete“ (Schuss) soll den Schacht (1) erreichen.
Das, wird aber durch die (im Hintergrund laufend) „Gravitationsänderungen“ erschwert.
