我试图找出以下代码有什么问题:

import pygame, sys, random, linecache
from pygame.locals import *

#Start Pygame, define Pygame objects
pygame.init()
hangmanSurfaceObj = pygame.display.set_mode((640,480), 0)
clock = pygame.time.Clock()

#Define colors
redColor = pygame.Color(255,0,0)
greenColor = pygame.Color(0,255,0)
blueColor = pygame.Color(0,0,255)
whiteColor = pygame.Color(255,255,255)
blackColor = pygame.Color(0,0,0)
tardisBlueColor = pygame.Color(16,35,114)
bgColor = whiteColor

#Import Images
hangmanImage = pygame.image.load('hangmanResources/hangman.png')

#Import sounds
sadTromboneSound = pygame.mixer.music.load('hangmanResources/sadTrombone.mp3')

#Import Font
fontObj = pygame.font.Font('hangmanResources/Avenir_95_Black.ttf', 18)

#Define global variables
currentWord = 0
usrWord = ''
screenWord = []
i = 0
currentChar = ''
guesses = 0

def terminate():
    pygame.quit()
    sys.exit()

def drawRects(tries):

    if tries<=0:
        hangmanSurfaceObj.fill(bgColor, pygame.Rect(242,65,65,65))
    if tries<=1:
        hangmanSurfaceObj.fill(bgColor, pygame.Rect(257,90,35,4))
    if tries<=2:
        hangmanSurfaceObj.fill(bgColor, pygame.Rect(261,110,27,1))
    if tries<=3:
        hangmanSurfaceObj.fill(bgColor, pygame.Rect(274,130,1,114))
    if tries<=4:
        hangmanSurfaceObj.fill(bgColor, pygame.Rect(198,160,76,1))
    if tries<=5:
        hangmanSurfaceObj.fill(bgColor, pygame.Rect(275,160,75,1))
    if tries<=6:
        hangmanSurfaceObj.fill(bgColor, pygame.Rect(210,244,64,85))
    if tries<=7:
        hangmanSurfaceObj.fill(bgColor, pygame.Rect(274,244,51,87))


def newGame(players):
    if players == 1:
        line_number = random.randint(0, 2283)
        usrWord = linecache.getline('hangmanResources/words.txt', line_number)
        usrWord = list(usrWord)
        del usrWord[-1]
        print(usrWord)
        screenWord = ['_']*len(usrWord)
        print(screenWord)

def checkChar(usrWord):
    print('hi')
    i=0
    addGuess = 1
    print(len(usrWord))
    while i <= (len(usrWord)-1):
        print('hi2')
        if currentChar.lower == usrWord[i]:
            print('hi3')
            screenWord[i] = currentChar
            addGuess = 0

    return addGuess


newGame(1)

while True:
    gameRunning = 1
    while gameRunning==1:


        for event in pygame.event.get(QUIT):
            terminate()

        for event in pygame.event.get(KEYDOWN):
            if event.key==K_ESCAPE:
                terminate()
            else:
                currentChar = event.unicode
                guesses +=checkChar(usrWord)
                print(currentChar)
                print(screenWord)
                msg = ''.join(screenWord)

                msgSurfaceObj = fontObj.render(msg, False, blackColor)
                msgRectObj = msgSurfaceObj.get_rect()
                msgRectObj.topleft = (10, 20)
                hangmanSurfaceObj.blit(msgSurfaceObj, msgRectObj)


        hangmanSurfaceObj.fill(bgColor)
        hangmanSurfaceObj.fill(blueColor, pygame.Rect(400,0,640,480))

        hangmanSurfaceObj.blit(hangmanImage, (0,0))

        if guesses<=7:
            drawRects(guesses)

        else:
            won=0
            gameRunning = 0


        pygame.display.update()
        clock.tick(30)

    newGame(1)

它应该是一个刽子手游戏,有一个悬挂柱,显示字母空白,右侧有一个蓝色矩形(游戏控件最终会去的地方)。

运行的时候出现了挂柱,左边的蓝色矩形出现了,虽然没有弹出错误,但是字母空白没有出现,蓝色矩形的一角连接着一个奇怪的蓝色框. 不过,更重要的是,我遇到的问题是,一旦您输入了一个字符,保存最终屏幕输出数据的字符串就不会改变。例如,如果猜测词是“Turtle”并且我输入“t”,那么它应该从['_','_','_','_','_','_']变为['t','_','_','t','_','_'],但事实并非如此。

我使用 Python 3.1.3 和 Pygame 1.9.1。

我在 Python 和 Pygame 文档中搜索了我正在使用的函数,但不幸的是我找不到资源。

可以在此处找到原始文件以及资源。

非常感谢!

您仅在 keydown 期间对短语进行 blitting,然后在您清洁屏幕的每一帧中。在 30 fps 时,如果您看到该短语的闪烁,您就很幸运了。您应该在键下检查帧,但在每一帧上都对帧进行 blit。

     ...
     for event in pygame.event.get(KEYDOWN):
        if event.key==K_ESCAPE:
            terminate()
        else:
            currentChar = event.unicode
            guesses +=checkChar(usrWord)
            print(currentChar)
            print(screenWord)
            msg = ''.join(screenWord)

    # Clean background
    hangmanSurfaceObj.fill(bgColor)

    # Then blit message
    msgSurfaceObj = fontObj.render(msg, False, blackColor)
    msgRectObj = msgSurfaceObj.get_rect()
    msgRectObj.topleft = (10, 20)
    hangmanSurfaceObj.blit(msgSurfaceObj, msgRectObj)

    ...

关于附加到控制框的蓝色矩形,这是因为您将控制框设置为 200px 宽,然后用您的 drawRects() 例程覆盖前 100px。

您可以将控制框设为 100px 宽:

hangmanSurfaceObj.fill(blueColor, pygame.Rect(400,0,640,480))

或修改 drawRects() 例程,使矩形不与控制框重叠。
