Python 2.7 TypeError:-=：'；实例'；和'；int'；用于pygame

我正在使用pygame，在处理我的健康栏时遇到了一个错误。当敌人通过某个点时，我希望生命值下降。游戏将类似于加拉加

帮助会很好。谢谢

class Health:
     def __init__(self, x, y, health):
         self.x = x
         self.y = y
         self.width = 300
         self.height = 96
         self.velocity = 0
         self.images = pygame.image.load('health.png') 
         self.numimages = 20    
         self.cImage = 0
         self.health = 100  

def update(self):  

    #if collide1 == True:
    #self.health -= 25 
    if self.health > 96:
        self.cImage = 0    
    if self.health >= 92 and self.health <= 96:
        self.cImage = 1
    if self.health >= 88 and self.health <= 92:
        self.cImage = 2

        self.cImage = 4    
    if self.health >= 76 and self.health <= 80:
        self.cImage = 5    
    if self.health >= 72 and self.health <= 76:
        self.cImage = 6

    if self.health >= 56 and self.health <= 60:
        self.cImage = 10

    if self.health >= 34 and self.health <= 39:
        self.cImage = 15    
    if self.health >= 29 and self.health <= 34:
        self.cImage = 16    
    if self.health >= 24 and self.health <= 29:
        self.cImage = 17    
    if self.health >= 18 and self.health <= 24:
        self.cImage = 18    
    if self.health >= 5 and self.health <= 18:
        self.cImage = 19    
    if self.health < 5:
        self.cImage = 19 
    if self.health == 0:
        pygame.quit()

稍后在发生错误的while循环中

if enemy.rect.y >= 699 or enemy2.rect.y >= 700 or enemy3.rect.y >= 700 or enemy4.rect.y >= 700 or enemy5.rect.y >= 700 or enemy6.rect.y >= 700 or enemy7.rect.y >= 700 or enemy8.rect.y >= 700 or enemy9.rect.y >= 700:
    health -= 10

那么，health是一个health（）对象，然后从中减去10？Python不知道你的意思。试试health.health-=10。这将从自我健康中减去10，这是一个整数。它起作用了。非常感谢你。python新手，曾一度被它所吸引：你可以使用

elif

，然后你不需要所有

和self.healt如果
self.health
是92，那么如果self.health>=92

和

和self.health，那么true就是
了
if enemy.rect.y >= 699 or enemy2.rect.y >= 700 or enemy3.rect.y >= 700 or enemy4.rect.y >= 700 or enemy5.rect.y >= 700 or enemy6.rect.y >= 700 or enemy7.rect.y >= 700 or enemy8.rect.y >= 700 or enemy9.rect.y >= 700:
    health -= 10
