我终于解决了碰撞问题，所以当我的鼠标悬停在圆圈上时，你点击鼠标左键，它就会填充。上升时会变，但下降时不会变

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)

width_1 = 2
width_2 = 2
width_3 = 2
width_4 = 2
# Un-fills circles

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)
    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
                if filled_1 == True:
                    circle_1 = pygame.draw.circle(screen, BLACK, [250, 230], 7, width_1)
            elif circle_2.collidepoint(x, y):
                # Lets the circle draw
                filled_2 = True
                width_2 = 0
                if filled_2 == True:
                    circle_2 = pygame.draw.circle(screen, BLACK, [250, 260], 7, width_2)               
            elif circle_3.collidepoint(x, y):
                # Lets the circle draw
                filled_3 = True
                width_3 = 0
                if filled_3 == True:
                    circle_3 = pygame.draw.circle(screen, BLACK, [250, 260], 7, width_3)
            elif circle_4.collidepoint(x, y):
                # Lets the circle draw
                filled_4 = True
                width_4 = 0
                if filled_4 == True:
                    circle_4 = pygame.draw.circle(screen, BLACK, [250, 260], 7, width_4)
    # Cleans the screen and sets the screen background
    screen.fill(GREEN)
    # 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)
    if filled_1 == True:
        filled_2 = False
        filled_3 = False
        filled_4 = False
        width_2 = 2
        width_3 = 2
        width_4 = 2
    elif filled_2 == True:
        filled_1 = False
        filled_3 = False
        filled_4 = False
        width_1 = 2
        width_3 = 2
        width_4 = 2
    elif filled_3 == True:
        filled_1 = False
        filled_2 = False
        filled_4 = False
        width_1 = 2
        width_2 = 2
        width_4 = 2
    elif filled_4 == True:
        filled_1 = False
        filled_2 = False
        filled_3 = False
        width_1 = 2
        width_2 = 2
        width_3 = 2
    # Update the screen
    pygame.display.flip()

运行这段代码，看看会发生什么，这很难解释

假设第二个被点击，那么

filled_1 = False
filled_2 = True
filled_3 = False
filled_4 = False

然后单击第三个。因此,

filled_1 = False
filled_2 = True
filled_3 = True
filled_4 = False

那么你就有了：

screen.fill(GREEN)

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)

它会（暂时）画两个黑色的圆圈

然后你要：

然后

elif filled_2 == True:
    filled_1 = False
    filled_3 = False
    filled_4 = False
    width_1 = 2
    width_3 = 2
    width_4 = 2

所以现在

filled_1 = False
filled_2 = True
filled_3 = False
filled_4 = False

这不是你想要的！现在

elif filled_3 == True:
    # Not run
elif filled_4 == True:
    # Not run

所以单击第三个按钮不起作用！这是因为您不存储所需的订单
我建议将此设置移动到单击处理程序内的零件中，设置为false：

if circle_1.collidepoint(x, y): # Lets the circle draw filled_1 = True width_1 = 0 filled_2 = False filled_3 = False filled_4 = False width_2 = 2 width_3 = 2 width_4 = 2 if filled_1 == True: circle_1 = pygame.draw.circle(screen, BLACK, [250, 230], 7, width_1) # ... etc ...
那很好用
现在，仍然存在一个问题。如果在第一次迭代中有一个事件，
circle_1
将不会被定义。这会使程序崩溃。你应该先定义圆

一些代码建议
而不是

BLACK = ( 0, 0, 0) GREEN = ( 3, 255, 3)
使用
他们为你而存在
而不是

thing_1 = ... thing_2 = ... ... other_thing_1 = ... other_thing_2 = ... ...
有一个字典列表：

circles = [ { "thing": ..., "other_thing": ... }, { "thing": ..., "other_thing": ... }, ... ]
使用
圆圈[1][“thing”]
而不是
thing\u 1
这允许您“简化”到：
这看起来可能并不简单，但它允许您使用循环，而不是反复指定：

采用这种设计：
问：如何添加另一个圆
答：您将其添加到
圆圈中
问：你怎么做才能使圆变大
答：您增加了它的
大小
属性
问：您如何改变检查碰撞的方式
答：您更改了检查碰撞的一个位置

看到好处了吗？：）
一个最小的、可运行的样本会带来奇迹。它可能适合你，但不适合我。去掉问题出现时不需要的所有内容（如果只需要一个圆圈，则只保留一个圆圈；如果只需要
if
的那部分，则始终保持为true并删除复选框），但保留所有需要的内容（例如，保留事件循环和显示更新）。好的，现在我明白了。我马上就去那太好了！现在您知道错误可能在哪里了，所以可以开始调试它了！从完整的代码开始，解决问题。慢慢地删除不重要的部分，直到你得到这个问题的代码。在某个地方，它会在行为之间切换。这就是问题所在。然后你可以改进你的问题。仅供参考：这个问题在meta上讨论。非常简单，谢谢你的额外建议。不过有一个问题，边界框是做什么的？
circles[X][“bounding box”]
相当于您的
circle\ux
。因此，当您绘制圆时返回的是
pygame.Rect
。我称它为“边界框”，因为它实际上是一个正方形，而不是你说的圆形。如果将圆变大，可以看到可以在圆外单击，因为正方形在圆外有角。
thing_1 = ... thing_2 = ... ... other_thing_1 = ... other_thing_2 = ... ...
