我的python代码一直存在问题，我正在使用pygame，random和math模块。我似乎无法在玩家健康栏上减少我的玩家的生命值之一。玩家健康栏固定在指定玩家的x和y位置，并且在其他玩家射击时不会降低玩家健康。
我已经尝试过在互联网上寻找答案，但没有找到答案。

HealthBar类仅在__init__()内计算其位置一次，因此它将永远不会更新。
也许它需要一个update()函数来重新生成它？
class Healthbar1(pygame.sprite.Sprite):
def __init__(self):
pygame.sprite.Sprite.__init__(self)
self.player_health = 100
self.drawn_health = 0 # don't regenerate unless it's changed
self.update() # generate the first bar
def change(self, new_health):
self.player_health = new_health
def update(self):
# DO THIS ALL SOMEWHERE ELSE, IT'S NOT PART OF A HEALTH-BAR
#for bullet1 in bullets1:
# if pygame.sprite.collide_rect(bullet1, player):
# bullet1.kill()
# player_health -= 5
# break
#if player_health == 0 or player_health <= 0:
# died()
# Only re-make the bar if it's different from last time
if self.player_health != self.drawn_health:
if self.player_health > 75:
player_health_color = green
elif self.player_health > 50:
player_health_color = yellow
else:
player_health_color = red
self.image = pygame.Surface((self.player_health, 25))
self.rect = self.image.get_rect()
self.image.fill(player_health_color)
self.drawn_health = self.player_health
