Could you explain a bit further please. Basically, I want to be able to SET a new relative location wrt. to the other actor. So if X world location of actor 1 is 10, and X world location of actor 2 is 20, then X relative location of actor 1 wrt. actor 2 would be -10, since actor 2 is set as origin.
So if I wanted to set the X relative location of actor 1 wrt. actor 2 as +10, aka in the world, it would become X = 30
How would I go about doing that? I hope I was able to explain my issue.
