Question

我是pygame的新手，但对编程却没有那么多，按下按钮后，我很难随时出现弹丸。如果我按住该按钮，它将起作用，但否则无法显示。我确实知道它会将其添加到硬币列表中，因为如果使用打印功能，我可以看到硬币列表，但绘制时看不到物体。我不知道我在做什么错。

import pygame
pygame.init()

WIDTH = 800
HEIGHT = 600

window = pygame.display.set_mode((WIDTH,HEIGHT))
pygame.display.set_caption("Why U NO WORK?")

class throw_coin(object):

    def __init__(self, color, x, y, radius):

        if event.type == pygame.QUIT:
            run = False
    window.fill((0,0,0))
    user.draw(window)
    user.move()
    pygame.display.update()

pygame.quit()

只是弄清楚了。这是新代码。感谢所有停下来尝试提供帮助的人。
