Im trying to offset a vector.
Im sure this is really easy, but Im struggling with the maths.
Basically I have 2 vectors: A & B. (Green & red)
Using them I am creating a new Vector: C (blue)
My goal is to ‘offset’ vector C so that it is centred to the origin. (Magenta)
I can’t figure out the method…
any help?
Hello,
Think about how you would offset a line between 2 points:

And then apply that thinking to your question with PVectors.
What is vector C? A+B or A-C with an offset added?
The offset can be a vector added to the starting point and ending point of C.
If you want to line it up to the middle of C you will have to consider that as well…
Do a search for PVectors here:
