So, tried to use atan2 and point self, in this variant it's not working, bullets not rotated. Of cause may be I did everything wrong, but do as can.
And I tried to rotate on angles that I can calculate in mind(90, 180, 270,0) and have another difficulty, if I shoot 12 bullets in one time, and rotate first bullet, next bullet rotate on the same angle as first plus angle of self, I mean, all bullets of the same type rotate together and I don't know how to make bullets rotate separately.
