仍然无法正确地将Cannon旋转至玩家Pygame

首先，加农炮的图像太高了。剪裁边框并使用较小的图像。例如：

图像的中心是佳能的旋转点。您可以将图像缩放到所需的任何大小。例如100x100：

self.shootsright = pygame.image.load("canss.png")self.shootsright = pygame.transform.smoothscale(self.shootsright, (100, 100))

另请参阅如何将图像（播放器）旋转到鼠标方向？。

无论如何，在旋转图像并计算矩形后，您必须将大炮 变灰 。

class enemyshoot:    def __init__(self,x,y,height,width,color):        self.x = x        self.y = y        # [...]        self.shootsright = pygame.image.load("canss.png")        self.shootsright = pygame.transform.smoothscale(self.shootsright, (100, 100))        self.image = self.shootsright        self.rect  = self.image.get_rect(center = (self.x, self.y))        self.look_at_pos = (self.x, self.y)        self.hitbox = (*self.rect.topleft, *self.rect.size)    def draw(self):        dx = self.look_at_pos[0] - self.x        dy = self.look_at_pos[1] - self.y        angle = (180/math.pi) * math.atan2(dx, dy)        self.image = pygame.transform.rotate(self.shootsright, angle)        self.rect  = self.image.get_rect(center = (self.x, self.y))        window.blit(self.image, self.rect)        self.hitbox = (*self.rect.topleft, *self.rect.size)    def lookAt( self, coordinate ):        self.look_at_pos = coordinate
