<p>我正在用python构建一个hangman游戏，由于某些原因，当试图在函数def drawGameOver中显示game over消息时，我得到了以下错误：“str”对象没有属性“render”。我的密码怎么了？我该如何在屏幕中间下方显示“游戏结束”？我已经给出了我认为唯一相关的代码。错误出现在“#display game over message”注释正下方的行。谢谢！在</p>
<pre><code># this function draws the game over screen
def drawGameOver(screen, fontObj, gameOverMsg, secretWord):
# draw a filled rectangle
pygame.draw.rect(screen,(0,0,255),(0,375,640,100))
# draw a border rectangle
# display the game over message
overMsg = fontObj.render(gameOverMsg, True, (255,255,255),(0,0,0))
overRect = overMsg.get_rect()
screen.blit(overMsg,overRect)
# display the secret word
print("")
def main():
# initialize pygame
pygame.init()
# create the screen
screen = pygame.display.set_mode((640,440))
# fill the screen w/ white
screen.fill((255,255,255))
fontObj = pygame.font.SysFont('bookantiqua', 28, True, False)
# here is the magic: making the text input
# create an input with a max length of 45,
# and a red color and a prompt saying 'type here: '
txtbx = eztext.Input(x=0, y=350, color=(0,0,0), prompt='You entered: ')
# get the secret word
secretWord = getRandomWord(words)
#variables to hold the incorrect and correct letters
missedLetters = ""
correctLetters = ""
#gameoverMsg is initialized to be empty
gameOverMsg = "Game Over"
#game is not over yet
gameIsDone = False
</code></pre>
