Not perfectly on point but since this is the first result google throws at people when searching for anything related to drag and construction scripts it might be be worth mentioning that there is still a bug where if you are dragging the component of the actor and not the actor the construction script will not run on drag. I ran into this problem just now and just couldn’t find a solution as to why would my construction script ignore dragging.
And then I’ve found this baby:

I would really like it if it would fire if I was dragging the components too tbh… but never would have guessed that I can select the root component separately from the actor - especially since moving the root component moves the actor as far as I’ve seen it.
