Many thanks for the quick response!
I've noticed that when the construction project starts, the bots fly normally for the first second (they don't prioritize the nearest objects). But that's not a huge problem. What bothers me more is that once the construction bots have finished (or are close to finishing) the frontmost area, it takes a while for the construction area to expand again. So I have to walk over to the other ghost objects to get them into my small area.
It's "only" a few seconds, but it still delays the building process considerably.
Perhaps you should also implement a minimum build size? Because "6x6", for example, is really too small.
Just to let you know i only thought about this now. This mod only speeds up construction if you actively move around. Total build time is determined entirely by the distance your drones must fly to a ghost and return. If you stand completely still, the total flight time for the whole blueprint remains exactly the same as in the vanilla game because the drones still need to cover the entire distance eventually.
The mod forces drones to prioritize the closest ghosts. If you walk alongside your blueprint as they build, the drones continuously target the nearest objects. They only make short trips, which significantly reduces the overall build time. I will increase the minimum area and adjust some values, but these tweaks will only benefit you if you keep moving during construction. You know what i mean?
