问题描述
我已经在pygame中制作了一个游戏，我想让有高分的thaat能够显示在show_go_screen的顶部。我只需要一个简单的解决方案-我不需要写得分最高的人，只需要显示show_go_screen顶部的数字即可。我知道Stack Overflow上已经对此有疑问，但是解决方案对我不起作用。

解决方法
创建一个名为highscore的变量，然后在玩家放松时检查当前得分是否高于highscore，如果当前得分高于score，则将highscore分配给{{1} }。然后，您可以轻松添加带有highscore变量作为文本的标签
score = 0
highscore = 0
# save score
# import shelve
# d = shelve.open('score.txt') # here you will save the score variable
# d['highscore'] = score # thats all,now it is saved on disk.
# d.close()
# A lot of your code
def show_go_screen():
screen.blit(background2,background_rect2)
draw_text(screen,str(highscore),50,WIDTH / 2,10) #change the x value accordingly
# more of your code
while running:
if game_over:
show_go_screen()
game_over = False
# Sprite groups
all_sprites = pg.sprite.Group()
mobs = pg.sprite.Group()
lasers = pg.sprite.Group()
powerups = pg.sprite.Group()
player = Player()
all_sprites.add(player)
for i in range(8):
spawnmob()
if score > highscore:
highscore = score
score = 0
# the rest of your code
