그래서 사각형 / 발사체 회전 에이 문제가 발생했습니다. 사각형 / 발사체가 회전하는 스프라이트와 함께 회전하도록하고 싶지만 내가 시도하는 코드가 작동하지 않습니다. 이 오류가 발생합니다. 'pygame.Surface' object has no attribute 'x'
코드 이동을 시도했고 코드를 변경하여 더 이상 오류가 발생하지 않도록 시도했으며 히트 박스를 사용해 보았지만 여전히 오류가 발생합니다. 이것은 내 두 스프라이트입니다
내가 시도하고있는 코드
self.dist = 100
dx = self.pin.x + self.dist*math.cos(-self.pin.angle*(math.pi/180)) -65 # why offset needed ?
dy = self.pin.y + self.dist*math.sin(-self.pin.angle*(math.pi/180)) -50 # why offset needed ?
