使用pygame在python中结束屏幕

如何解决使用pygame在python中结束屏幕

我正在创建我的第一个 Pygame 项目，一个飞扬的小鸟，但我想显示一个结束屏幕，在玩家离开后立即显示分数。我正在使用以下代码。

import pygame
import pygame.freetype
import random
import sys
pygame.init()
pygame.font.init()
GAME_FONT = pygame.freetype.Font("OpenSans-Bold.ttf",24)
surface = pygame.display.set_mode((320,568))
end_screen = pygame.display.set_mode((320,568))
bg = pygame.image.load('bg.png')
bird = pygame.image.load('player.png')
text = pygame.font.Font(None,50)
pole_width = 70
pole_gap = 100
pole_x = 350 - pole_width
top_pole_height = random.randint(100,200)
pole_color = (220,85,57)
bird_x = 0
bird_y = 0
score = 0
clock = pygame.time.Clock()
while True:
    for event in pygame.event.get():

        # if event object type is QUIT
        # then quitting the pygame
        # and program both.
        if event.type == pygame.QUIT:
            # deactivates the pygame library
            pygame.quit()

            # quit the program.
            sys.exit()
    pygame.event.get()
    keys = pygame.key.get_pressed()
    if keys[pygame.K_DOWN]:
        bird_y = bird_y + 6
    elif keys[pygame.K_UP]:
        bird_y = bird_y - 6
    if pole_x <= -pole_width:
        pole_x = 320
        top_pole_height = random.randint(100,400)
        score = score+20
    surface.blit(bg,(0,0))
    surface.blit(bird,(bird_x,bird_y))
    pygame.draw.rect(surface,pole_color,pygame.Rect(pole_x,pole_width,top_pole_height))  # upper pole
    pygame.draw.rect(surface,(pole_x,top_pole_height + pole_gap,568))  # lower pole
    if pole_x <= bird_x + 50 and bird_x <= pole_x + pole_width:
        # In the video you will see the line below
        # if bird_y <= top_pole_height or bird_y >= top_pole_height + pole_gap:
        # However,the bird bottom has to more than the top pole height and gap to
        # hit the bottom pole.
        if bird_y <= top_pole_height or bird_y + 50 >= top_pole_height + pole_gap:
            # score = score - 5
            print(score)
            pygame.quit()
            sys.exit()
        # if score<0:
            # pygame.quit()
            # sys.exit()
    GAME_FONT.render_to(surface,0),f"score:{score}",0))
    pole_x = pole_x - 5
    pygame.display.flip()
    pygame.display.update()
    clock.tick(60)

解决方法

添加一个gameover变量，当玩家死亡时将其设置为True，并在循环中检查它：

gameover = False
score = 0
clock = pygame.time.Clock()
while True:
    for event in pygame.event.get():

        # if event object type is QUIT
        # then quitting the pygame
        # and program both.
        if event.type == pygame.QUIT:
            # deactivates the pygame library
            pygame.quit()

            # quit the program.
            sys.exit()
    pygame.event.get()
    keys = pygame.key.get_pressed()
    if keys[pygame.K_DOWN]:
        bird_y = bird_y + 6
    elif keys[pygame.K_UP]:
        bird_y = bird_y - 6
    if gameover:
       if keys[pygame.K_SPACE]:
          sys.exit()
    if not gameover:
        if pole_x <= -pole_width:
            pole_x = 320
            top_pole_height = random.randint(100,400)
            score = score+20
        surface.blit(bg,(0,0))
        surface.blit(bird,(bird_x,bird_y))
        pygame.draw.rect(surface,pole_color,pygame.Rect(pole_x,pole_width,top_pole_height))  # upper pole
        pygame.draw.rect(surface,(pole_x,top_pole_height + pole_gap,568))  # lower pole
        if pole_x <= bird_x + 50 and bird_x <= pole_x + pole_width:
            # In the video you will see the line below
        # if bird_y <= top_pole_height or bird_y >= top_pole_height + pole_gap:
        # However,the bird bottom has to more than the top pole height and gap to
        # hit the bottom pole.
            if bird_y <= top_pole_height or bird_y + 50 >= top_pole_height + pole_gap:
            # score = score - 5
            gameover = True
       
        GAME_FONT.render_to(surface,0),f"score:{score}",0))
        pole_x = pole_x - 5
    else:
        GAME_FONT.render_to(surface,0))

    pygame.display.update()
    clock.tick(60)

此外，您不需要 display.flip() 和 display.update()，两者都可以。

这个版本就是这样，它在最后等待按键。我不得不更改表面的一些图像，因为我没有图像，而字体因为在我的计算机上找不到该字体。
