pygame圆填充不正确

Question

我正在用pygame和python做一个选择题游戏。我做了一个单独的程序来处理循环填充/取消填充，我基本上是把它放下。圆圈在上升的过程中会充满，但在下降的过程中不会。很难解释，我建议你运行代码来真正理解我的意思。任何帮助都将不胜感激！你知道吗

这是我的密码：

# Imports a library of functions!
import pygame
import random
# Initializes the game engine
pygame.init()
# Defines the colors
BLACK = (  0,   0,   0)
GREEN = (  3, 255,   3)
# Controls the width of the circle
width_1 = 2
width_2 = 2
width_3 = 2
width_4 = 2
# Un-fills circles
filled_1 = False
filled_2 = False
filled_3 = False
filled_4 = False
# Sets the height and width of the screen
size = [720, 575] 
screen = pygame.display.set_mode(size)
# Loops until the user clicks the close button
done = False
clock = pygame.time.Clock()
# While loop
while not done:
    # Leaves the fps at 30
    clock.tick(30)
    # Cleans the screen and sets the screen background
    screen.fill(GREEN)
    for event in pygame.event.get(): # If user did something
        if event.type == pygame.QUIT: # If user clicked close
            done = True
        elif event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
            # Finds where you clicked            
            x, y = event.pos
            # Check if mouse was over it
            if circle_1.collidepoint(x, y):
                # Lets the circle draw
                filled_1 = True
                width_1 = 0
            elif circle_2.collidepoint(x, y):

        width_2 = 2
        width_3 = 2
    # Circles
    circle_1 = pygame.draw.circle(screen, BLACK, [250, 230], 7, width_1)
    circle_2 = pygame.draw.circle(screen, BLACK, [250, 260], 7, width_2)
    circle_3 = pygame.draw.circle(screen, BLACK, [250, 290], 7, width_3)
    circle_4 = pygame.draw.circle(screen, BLACK, [250, 320], 7, width_4)
    # Update the screen
    pygame.display.flip()

您必须将其他变量设置为False，当您处理正在按下的鼠标按钮时，这些变量不会被单击。例如，一旦filled_1被设置为True，没有任何东西会将它设置为False，因此第一个if语句将始终执行，而其他语句将被设置为False。你知道吗

也有更简单的方法来完成你想做的事情，我想你可能会受益于看一些Python documentation，它会使你的文章更简洁，易读，而且在很多情况下，更快。你知道吗
