如何解决pygame 秤的特定问题
我正在使用 pygame 为我的 skl 项目制作游戏。它是一个简单的平台游戏。我喜欢编码，但我对游戏开发不是很感兴趣，在我的游戏中，我试图使碰撞箱矩形成为更好的形状，但它只能从精灵的右侧缩放，因为矩形从左上角开始，所以我的碰撞在精灵的右侧很好，但在精灵的左侧它有斑点
我试图在任何地方找到答案，甚至在这个网站上提问，但我得到的所有答案都太高级了或者我太愚蠢了我试图让我的敌人班级规模化
我正在使用 self.rect.inflate(-40,-20)
但它只适用于我的精灵的一侧
所附的 ss 是图片说明，第一张图片是我的hitBox 的样子（蓝色）
第二个是我想要的
这是我的敌人类
#ENEMY SPRITE class
class Enemy(pygame.sprite.Sprite):
def __init__(self,x,y):
pygame.sprite.Sprite.__init__(self)
self.image = pygame.image.load('img/blob.png')
self.image = pygame.transform.scale(self.image,(65,35))
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
self.move_direction = 1
self.move_counter = 0
def update(self): #update enemy (movement)
self.rect.x += self.move_direction
self.move_counter += 1
if abs(self.move_counter) > 50:
self.move_direction *= -1
self.move_counter *= -1
这是我的全部代码
