pygame - 在 pygame 中保存高分

Question

我知道这是很多代码，但我确实需要帮助来制作它，以便只要用户继续玩(不进入 sys.quit)，高分就会保存并可以通过 highscore 函数显示。我已经工作了几个小时，无法弄清楚这部分。抱歉，有这么多代码。也愿意采取任何方法使其运行得更好或更流畅。

def playagain():
    print "Would you like to play again?"
    global playername
    choice=raw_input("Or do you want to see the current high scores: ")
    choice1=choice.lower()
    if choice=='yes' or choice=='y':
        playername=raw_input('Name:  ')
        main_loop(random.randint(3.0,6.0))
    elif choice=='high scores' or choice=='hs':
        highscores()
    elif choice=='no' or choice=='n' or choice=='goodbye' or choice=='bye' or choice=='exit' or choice=='quit':

我对您的代码做了一些简单的修改。看看我添加的评论。这应该为您提供一个良好的起点。

import pygame, sys, random

from time import *
from pygame import *
from pygame.locals import *

# define colors at top level of the script
WHITE = (255, 255, 255)
BLUE  = (0  ,   0, 255)
RED   = (255,   0,   0)
GREEN = (0  , 255,   0)

# keep track of highscores
scores = []

def get_window_and_font():
    """Returns a tuple of a font and the surface of a newly created window"""
    pygame.init()
    pygame.display.set_caption('Tic-toc!')
    return pygame.font.SysFont(None, 48), pygame.display.set_mode((500, 400), 0, 32)

def playagain():
    """Returns if the player wants to play again"""
    print "Would you like to (p)lay again or (n)ot?"
    choice = raw_input("Or do you want to see the current (h)igh scores: ").lower()
    # use 'in' to check choices of fewer code
    if choice in ('yes', 'y', 'p', 'play', 'again'):
        return True
    elif choice in ('high scores', 'hs', 'h'):
        highscores()
        return True
    elif choice in ('no', 'n', 'goodbye', 'bye', 'exit', 'quit'):
        return False
    else:
        playagain()

def highscores():
    basicFont, windowSurface = get_window_and_font()

    # use enumerate to get the index of the sorted elements in our highscores
    # highscores are sorted by score, descending
    for i, (name, score) in enumerate(sorted(scores, key=lambda x: -x[1])):
        # use list comprehension to create a nice color effect in highscore :-)
        color = tuple([max(0, 255-i*x) for x in (15, 25, 40)])
        nameimage = basicFont.render(name, True, color)
        namerect = nameimage.get_rect()
        namerect.left, namerect.y = 40, 10 + (i*(namerect.height + 10))
        windowSurface.blit(nameimage,namerect)
        scoreimage = basicFont.render(str(score), True, color)
        scorerect = scoreimage.get_rect()
        scorerect.right, scorerect.y = 480, namerect.y
        windowSurface.blit(scoreimage, scorerect)
        for d in range(namerect.right + 25, scorerect.left-10, 25):
            pygame.draw.rect(scoreimage, color, pygame.Rect(d, scorerect.centery, 5, 5))

    pygame.display.update()
    # just check for MOUSEBUTTONUP and QUIT, using the filter argument of .get()
    while not any(pygame.event.get((MOUSEBUTTONUP, QUIT))):
        sleep(0.1)
    pygame.quit()

def play_game():
    """this function handles a round of the game and returns the playername and his score"""
    timer = random.randint(3.0,6.0)
    playername = raw_input('Name:  ')
    finaltime = 0
    basicFont, windowSurface = get_window_and_font()
    # keep running while no QUIT event is in the queue
    while not any(pygame.event.get(QUIT)):
        # clear the screen every tick
        windowSurface.fill((0,0,0))
        timer -= .01
        if timer <= 0.0099:
            textnew  = basicFont.render('0.00', True, WHITE, RED)
            textRectnew = textnew.get_rect()
            textRectnew.centerx = windowSurface.get_rect().centerx
            textRectnew.centery = windowSurface.get_rect().centery
            windowSurface.blit(textnew, textRect)
            pygame.display.update()
            break

        # we are only interested in button1, so discard the rest
        button1, _, _ = pygame.mouse.get_pressed()
        text = basicFont.render(str(timer), True, WHITE, BLUE)
        textRect = text.get_rect()
        textRect.centerx = windowSurface.get_rect().centerx
        textRect.centery = windowSurface.get_rect().centery

        # use collidepoint to check if mouse is above the rect
        # you could also use the MOUSEBUTTONUP event instead of mouse.get_pos()
        if button1 == 1 and textRect.collidepoint(pygame.mouse.get_pos()):
            text = basicFont.render(str(timer), True, WHITE, BLUE)
            finaltime = timer
            break

        sleep(.01)
        windowSurface.blit(text, textRect)
        pygame.display.update()

    pygame.quit()

    return playername, finaltime

def main():
    keep_playing = True
    while keep_playing:
        # play_game returns the playername and his score
        # store that in our highscore list
        scores.append((play_game()))
        # keep playing if the player wants to
        keep_playing = playagain()

# good habit to use the __name__ magic variable
if __name__ == '__main__':
    main()

您根本不需要global。

我认为关闭并重新打开窗口以在 pygame 和 CLI 之间切换有点奇怪，但我在将相关代码移动到其自己的函数 get_window_and_font 的同时保留了这部分代码完整。

稍后您可能希望将游戏划分为不同的场景，例如标题屏幕、名称输入屏幕、游戏屏幕和高分屏幕，但这超出了本答案的范围。
