Pygame 枪在左侧问题上向上旋转视线向下

Question

所以我这里有这把枪，它朝我的鼠标 x 和鼠标 y 位置旋转，但问题（视频）是枪倒置了。有没有办法让我的枪的图像不倒置，并做与我的枪朝向右侧相同的运动？就像左侧的枪由于某种原因倒置了，我根本不知道该怎么做

枪支图片：

my gun draw(self)

    def draw(self,drawX,drawY):

        self.rect.topleft =  (drawX,drawY)

            # the gun's hitbox

            # rotating the gun

        dx = self.look_at_pos[0] - self.rect.centerx

        dy = self.look_at_pos[1] - self.rect.centery 

            

        angle = (180/math.pi) * math.atan2(-dy, dx)

      

        gun_size = self.image.get_size()

        pivot = (8, gun_size[1]//2)

            

        blitRotate(window, self.image, self.rect.center, pivot, angle)

    def lookAt( self, coordinate ):

            

        self.look_at_pos = coordinate

        # LOL THESE IS THE HAND

        self.shootsright = pygame.image.load("hands.png")

        self.image = self.shootsright

        self.rect  = self.image.get_rect(center = (self.x, self.y))

        self.look_at_pos = (self.x, self.y)

        self.isLookingAtPlayer = False

        self.look_at_pos = (x,y)

            

        self.hitbox = (self.x + -18, self.y, 46,60)

    def draw(self,drawX,drawY):

        self.rect.topleft =  (drawX,drawY)

            # the gun's hitbox

            # rotating the gun

        dx = self.look_at_pos[0] - self.rect.centerx

        dy = self.look_at_pos[1] - self.rect.centery

        gun_size = self.image.get_size()

        pivot = (8, gun_size[1]//2)

            

        blitRotate(window, self.image, self.rect.center, pivot, angle)

    def lookAt( self, coordinate ):

            

        self.look_at_pos = coordinate
