How's Add Actor Local Offset calculated?

No, they are independent of each other, it is a modular building system, similar to Ark or Rust. The code isn’t complicated, I simply get the transform of Actor A, then spawn actor B at the same transform of actor A and then use ‘add actor local offset’ to ‘snap’ actor B to actor A.

I’m working on a multiplayer project and basically I’m trying to make a collision check before I spawn the actor. I want to use a box trace that will look if the box trace is colliding with any other actor…
