主要问题自参考。您需要更新 self.walkCount = 0.

这段代码对我有用：

def draw(self, win):

        if self.walkCount >= len(walkLeft): # assume left/right same length
            self.walkCount = 0  # use self
            
        print(self.walkCount)

        if self.left:
            win.blit(walkLeft[self.walkCount//3], (round(self.x),round(self.y)))
            self.walkCount += 1
        elif self.right:
            win.blit(walkRight[self.walkCount//3], (round(self.x),round(self.y)))
            self.walkCount += 1
        else:
            win.blit(char, (round(self.x),round(self.y)))
