Ayuda Pygame (Class & Def Main)

[Psycho Silene]

Hola!
Es mi primer año dando programación en la Universidad y se me da bastante mal, quería saber si alguien podría ayudarme a solucionar el siguiente problema.
Tengo que programar un mini-juego con Pygame, y a base de buscar tutoriales y más tutoriales he conseguido hacer el siguiente código y que funcione perfectamente.
El problema es que 2 de los requisitos mínimos son utilizar Clases y usar la función Def Main, y por más que lo he intentado soy incapaz de incorporarlos al código.
Podría ayudarme alguien? Gracias!

Hola, bienvenido.

Con gusto te ayudamos, pero poné el código dentro de las etiquetas [ code] y [ /code] (sin espacios) para que no se pierda la sangría. Además, subí los sprites (imágenes) de tu código para que lo podamos ejecutar.

Saludos!

Hola. Bueno, la consigna de "usar clases" es muy vaga, ¿clases para qué? Lo que generalmente se hace en PyGame, y que te recomiendo, es crear una clase por cada tipo de sprite en el juego. De modo que, en tu caso, deberías clear una clase Player y otra Enemy, que hereden de pygame.sprite.Sprite. Acá tenés un ejemplo (chequeá la clase Block): https://recursospython.com/codigos-de-fu...is-pygame/.

En cuanto a la función main(), eso es más fácil. Meté todo el código que está debajo de tus funciones en una función que se llame main(), y en la última línea del código la llamás.

Saludos!
