Llega a la bandera
Parte de la sección Mundos del Journey de Pygame de Coddy. Lección 35 de 35.
El último paso le da un final a la cueva. Llega a la bandera pasando por la puerta y ganarás; pierde la tercera vida y la partida termina.
La casilla F es la bandera, un Rect llamado flag. Al tocarla, se establece won = True. Pon todo lo que se mueve bajo una sola condición para que el juego se detenga en cualquiera de los dos finales:
if lives > 0 and not won:
# teclas, movimiento, monedas, peligros, blobs,
# la llave, la bandera y la cámaraEl dibujo se mantiene fuera de la condición: el último fotograma permanece en pantalla y, encima, aparece el resultado centrado:
if won:
message = font.render("You win!", True, (255, 255, 255))
screen.blit(message, message.get_rect(center=(WIDTH // 2, 150)))
elif lives == 0:
message = font.render("Game over", True, (255, 255, 255))
screen.blit(message, message.get_rect(center=(WIDTH // 2, 150)))Juega desde el principio: el primer hoyo, el escalón, el blob, las púas, la llave y la puerta. Después cambia el mapa y haz tuya la cueva.
