I have a line ahead of my moving object to serve as a raycast and its aligned with the object's movement direction. But I want also some extra lines according to an angle related to the 'head' of the moving object.
This position is always changing; I also have a velocity vector to see the direction of the object as well, I use that to trace the front line ray of my object but not sure how to use to calculate this new line.
In this picture, my object is moving to the right and up. I want to trace a new line but 30 degrees from this one. How do I do that?
