WIN.fill(WHITE)

while True:
    Next_alive = []
    Next_dead = []
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit(0)
    x = SIZE[0]
    y = SIZE[1]
    for i in range(10,x-10):
        for j in range(10,y-10):
            if rule(i,j):
                Next_alive.append((i,j))
    WIN.fill(WHITE)
    print('Alive =',len(list(set(Next_alive))))




    for x,y in list(set(Next_alive)):
        pygame.draw.rect(WIN,RED,(x,y,1,1))
    # for x,y in Next_dead:
    #     pygame.draw.rect(WIN,GREEN,(x,y,1,1))
    gen += 1
    print(gen)

    pygame.display.update()

该代码的实现策略是遍历所有像素点,判断每个像素点下一代的状态,然后每个像素点状态写入数组,根据数组更新画面

这个方法有点暴力,像素过多的话会大量消耗资源,很慢
