Question

下面是我想在高中学习的python初学者课程中制作的游戏代码。我一直遇到的问题是我做了一个按钮功能，但是每次我点击按钮它都会显示水平选择功能（我想要的那个），但只有我点击鼠标的时间，但是一旦我放手它会回到主菜单。如果有人可以帮助我，我会非常感激：）

Imports
import pygame
import time
import random

# Define some colors
BLACK    = (   0,   0,   0)
WHITE    = ( 255, 255, 255)
GREEN    = (   0, 255,   0)
RED      = ( 255,   0,   0)

pygame.init()

#Music and Sound Imports
pygame.mixer.music.load("MenuMusic.wav")

# Set the width and height of the screen [width, height]
size = (1920, 980)
screen = pygame.display.set_mode(size)

pygame.display.set_caption("Panda On The Run v1")

# Loop until the user clicks the close button.
done = False

# Used to manage how fast the screen updates
clock = pygame.time.Clock()

#Main Menu
Main_menu = pygame.image.load("Main Menu Backgroundv3.png")


    # -------- Main Program Loop -----------
def level_select():
    screen.fill(WHITE)

def button(msg, x,y,ic,ac,action = None):
    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()
    #Level Select Colour Change
    if x + 625 > mouse[0] > x and y + 225 > mouse[1] > y:
        font = pygame.font.SysFont('Calibri', 100, True, False)
        text = font.render(msg,True,ac)
        screen.blit(text, [90, 420])
        if click[0] == 1 and action != None:

        screen.blit(text, [1450, 420])
    #Controls Colour Change
    if 35 + 800 > mouse[0] > 35 and 600 + 500 > mouse[1] > 600:

        text = font.render("Controls",True,RED)
        screen.blit(text, [150, 770])

        pygame.display.update()
        clock.tick(15)




    # First, clear the screen to white. Don't put other drawing
    # above this, or they will be erased with this command.

    # --- Go ahead and update the screen with what we've drawn.
    pygame.display.flip()

    # --- Limit to 60 frames per second
    clock.tick(60)

# Close the window and quit.
# If you forget this line, the program will 'hang'
# on exit if running from IDLE.
game_intro()
pygame.quit()

它返回主菜单，因为level_select()什么都不做。它用白色填充屏幕，然后返回bottom()，您再次进入主菜单。不要指望（几乎）空函数会做一些魔术。

如果您要留在level_select，那么您必须做点什么。

如果level_select必须显示新菜单或其他内容，则在此功能中创建新的“mainloop”，它将显示level_select中的元素，检查事件等。

每个"stage"都需要拥有"mainloop"（图片上为"while running"），如下所示：

但是如果你使用课程会更容易。
