为什么我的代码无法在 pygame 中打开 window？

Question

到目前为止应该只能打开window，但在测试过程中，它不会打开window，尽管没有显示任何错误。

我已经尝试使用“pygame.disply.flip()”而不是更新，但没有任何改变。我也在终端中得到这个： pygame2.1.2（SDL 2.0.18，Python3.10.1）来自 pygame 社区的问候。 https://www.pygame.org/contribute.html 就是这样。

import pygame
import random

pygame.init()

class DrawInformation:
    BLACK = 0, 0, 0
    WHITE = 255, 255, 255
    GREEN = 0, 255, 0 
    RED = 255, 0, 0
    GREY = 128, 128, 128
    BACKGROUND_COLOR = WHITE

    SIDE_PAD = 100
    TOP_PAD = 150

    def __init__(self, width, height, lst):
        self.width = width
        self.height = height
        
        self.window = pygame.display.set_mode((width, height))
        pygame.display.set_caption("Sorting Algorithm Visualization")
        self.set_list(lst)

    def set_list(self, lst):
        self.list = lst
        self.min_val = min(lst)
        self.max_val = max(lst)

        self.block_width = round((self.width - self.SIDE_PAD) / len(lst))
        self.block_height = round((self.height - self.TOP_PAD) / (self.max_val - self.min_val))
        self.start_x = self.SIDE_PAD // 2

def generate_starting_list(n, min_val, max_val):
    lst = []

    for _ in range(n):
        val = random.randint(min_val, max_val)
        lst.append(val)
    
    return lst

def main():
    run = True
    clock = pygame.time.Clock()

    n = 50
    min_val = 0
    max_val = 100


    lst = generate_starting_list(n, min_val, max_val)
    draw_info = DrawInformation(800, 600, lst)

    while run:
        clock.tick(60)
        
        pygame.display.update()

        for event in pygame.event.get():
            if event == pygame.QUIT:
                run = False
    
    pygame.quit()

    if __name__ == "__main__":
        main()

这是我目前所知道的...它还说“draw_info”没有被 pylance 和 idk 访问，为什么？？

Answer 1

行

if __name__ == "__main__":
    main()

的目的是 def main() 所以程序启动的时候不是运行

这是更正后的代码。

import random

pygame.init()

class DrawInformation:
    BLACK = 0, 0, 0
    WHITE = 255, 255, 255
    GREEN = 0, 255, 0 
    RED = 255, 0, 0
    GREY = 128, 128, 128
    BACKGROUND_COLOR = WHITE

    SIDE_PAD = 100
    TOP_PAD = 150

    def __init__(self, width, height, lst):
        self.width = width
        self.height = height
        
        self.window = pygame.display.set_mode((width, height))
        pygame.display.set_caption("Sorting Algorithm Visualization")
        self.set_list(lst)

    def set_list(self, lst):
        self.list = lst
        self.min_val = min(lst)
        self.max_val = max(lst)

        self.block_width = round((self.width - self.SIDE_PAD) / len(lst))
        self.block_height = round((self.height - self.TOP_PAD) / (self.max_val - self.min_val))
        self.start_x = self.SIDE_PAD // 2

def generate_starting_list(n, min_val, max_val):
    lst = []

    for _ in range(n):
        val = random.randint(min_val, max_val)
        lst.append(val)
    
    return lst

def main():
    run = True
    clock = pygame.time.Clock()

    n = 50
    min_val = 0
    max_val = 100


    lst = generate_starting_list(n, min_val, max_val)
    draw_info = DrawInformation(800, 600, lst)

    while run:
        clock.tick(60)
        
        pygame.display.update()

        for event in pygame.event.get():
            if event == pygame.QUIT:
                run = False
    
    pygame.quit()
