pygame.sprite.Group（）中的对象方法

Question

I have a couple of sprite groups checking for collisions with each other and I want to access the method of one member of the sprite group as follows...

for hit in pygame.sprite.groupcollide(badSprites, Missiles, 0, 1):
     hit.health(100)
     hit.printMessage("NO")

For some reason the hit.printYes method works but the hit.health one gives me a type error

TypeError: 'int' object is not callable

Here's the method inside my colliding object...

def health(self, damage):
    self.damage = damage
    self.health -= damage
    return self.health
def printMessage(self, message):
    print(message)

As you can see I just want to alter the health of the object when it collides with the missile but it appears I can only pass strings not numbers. I tried sending "100" as a string and then type casting inside health() but that didn't work either. Perhaps my code is wrong elsewhere.

您不能拥有与属性同名的方法，不能将方法更改为set_health或类似的名称
