So I have no problem creating a straight line from my character. Now I’d like another line at the end of this line, perpendicular to it (regardless of my character’s rotation).
Here is an image of my blueprint for the straight line starting from my character:
I added some extra markings to your drawing. (Point A, length b, vector c and vector d that is perpendicular to c) Point A is the end of your original line. b is some length you decide.
First you need to figure out d. You can either do so by rotating c by 90 degrees with RotateVector or by instead getting the right vector from the world rotation of your first person mesh.
Now you multiply d by b, let’s call it db. You subtract db from A to get the start of the new line and add db to A to get the end of the new line.
