Question

*我是pygame的新手，必须为课程项目创建一个主菜单。我目前仅实现了按钮交互功能，该按钮更改了按钮的颜色，现在我试图进入到单击按钮将在屏幕上绘制新页面的阶段。我隐约地理解了鼠标单击和MOUSEBUTTONDOWN

的概念

import pygame


pygame.init()

screen = pygame.display.set_mode((800, 600))
clock = pygame.time.Clock()

BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
HOVER_COLOR = (50, 70, 90)

#Background Music
pygame.mixer.music.load('game.ogg')
pygame.mixer.music.set_endevent(pygame.constants.USEREVENT)
pygame.mixer.music.play()
pygame.display.update()
clock.tick(15)

#Background
bg = pygame.image.load("greybackground.png")


#Fonts
FONT = pygame.font.SysFont ("Times New Norman", 60)


text1 = FONT.render("START", True, WHITE)
text2 = FONT.render("OPTIONS", True, WHITE)
text3 = FONT.render("ABOUT", True, WHITE)

#Buttons
rect1 = pygame.Rect(300,300,205,80)
rect2 = pygame.Rect(300,400,205,80)
rect3 = pygame.Rect(300,500,205,80)

buttons = [
    [text1, rect1, BLACK],
    [text2, rect2, BLACK],
    [text3, rect3, BLACK],
    ]

def game_intro():
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                return
            elif event.type == pygame.MOUSEMOTION:
                for button in buttons:
                    if button[1].collidepoint(event.pos):
                        button[2] = HOVER_COLOR
                    else:
                        button[2] = BLACK

                        screen.blit(bg, (0, 0))
        for text, rect, color in buttons:
            pygame.draw.rect(screen, color, rect)
            screen.blit(text, rect)

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

def loop():
    clock = pygame.time.Clock()
    number = 0
    # The button is just a rect.
    button = pygame.Rect(300,300,205,80)
    done = False
    while not done:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                done = True
            # This block is executed once for each MOUSEBUTTONDOWN event.
            elif event.type == pygame.MOUSEBUTTONDOWN:
                # 1 is the left mouse button, 2 is middle, 3 is right.
                if event.button == 1:
                    # `event.pos` is the mouse position.
                    if button.collidepoint(event.pos):
                        # Incremt the number.
                        number += 1

game_intro()
loop()
pygame.quit()
