Traté de poner huevos en movimiento después de la última línea de la función "check_catch", pero iba muy rápido y solo creó dos huevos. Copié este código de un libro, y es un colector de huevos, pero después de atrapar su primer huevo , todo se detiene de inmediato. ¿Alguien conoce el problema? Pienso dónde está el problema. Probablemente esté en la función "check_catch", pero nada de lo que soluciono funciona

La mejor respuesta

Al configurar difficulty_factor = 100, detienes significativamente el juego, ya que lo usas para cambiar la velocidad de los huevos en inincrease_score(points):

egg_speed = int(egg_speed * difficulty_factor)
egg_interval = int(egg_interval * difficulty_factor)

Cambie difficulty_factor a un valor como 0,8 o 0,9, cuanto más bajo, más rápido, y el juego funciona muy bien. Establecerlo por encima de 1 hace que los huevos sean más lentos en cada iteración

En el aumento de puntuación, cambia egg_speed multiplicándolo por el factor de dificultad.

Entonces, después de atrapar el primer huevo, la velocidad es de 50000.

¡Intenta encontrar una manera de reducir la velocidad del huevo!
