当我将我的PLAYER1和player2类我不断收到错误类型错误：参数1必须pygame.Surface，不是str的

Question

，我得到的错误是

File "C:\Users\Nicholas\PycharmProjects\MortalKombat\Fighting.py", line 149, in main 
allsprites.draw(screen) 
File "C:\Python32\lib\site-packages\pygame\sprite.py", line 475, in draw 
self.spritedict[spr] = surface_blit(spr.image, spr.rect) 
TypeError: argument 1 must be pygame.Surface, not str 

早些时候，我得到一个视频系统不初始化错误，并发布了一个问题，导致我在这个程序中导致我的主程序中的错误的问题。

我修复了这个错误，但是当我将player1，player2和记分板添加到pygame.sprites.Group（）时出现了上面的错误。 Fighting.py的代码如下。我做

allsprites.draw(screen) 

，我还以为屏幕

screen = pygame.display.set_mode((900,400)) 

是pygame.Surface的说法，但我不知道海峡的意思。

Answer 1

我接过来一看，我觉得这一段代码导致错误：

self.player1Txt = open("Player1", "r") 
    self.image = self.player1Txt.read() 
    self.player1Txt.close() 

和

self.player2Txt = open("Player2", "r") 
    self.image = self.player2Txt.read() 
    self.player2Txt.close() 

现在我不知道为什么你正在计划阅读文本文件，但问题是，创建self.image时，你必须以这样的格式：

self.image = pygame.Surface([width, height]) 

如果您想使用的图像文件，你也可以做这样的事情：

self.image = pygame.transform.scale(player_image, (width, height)) 

，因为我认为这是你试图用文本文件做。

我希望这有助于！
