WebI had to make a cone trace recently too and ended up with a very different solution, maybe this will help you. So I just use a box trace that's the size of the end of the cone I want. Then I check the rotation between the forward vector used for the box trace and the lookat angle between the start of the box trace (dragons face) and the hit result.
