TL;DR
Add an option that allows logistic requests to control whether items come from planetary logistics or space platform logistics, preventing unwanted supply loops in inter-platform logistics.What?
With the addition of transporting items between space platforms in version 2.1, we can now transport items between different space platforms. This is a great feature, but the current system lacks control over the priority of requested items.I designed a stationary logistics hub on Nauvis (with a function similar to a buffer chest) to receive fusion fuel cells transported from Aquilo and distribute them to other platforms and Nauvis.
The advantage of this design is that ships that need fusion fuel cells and do not pass through Aquilo can refuel at Nauvis, without requiring Nauvis to launch fuel to the ships by rockets.
I use a latch to control the hub's requests — when fusion fuel cells < 10, send a request for 500 items; after the 500 requested items are fulfilled, remove the request until it drops below 10 again. Because when there is an active request, the hub cannot provide items.
However, requests controlled by signals cannot control their supply source. This causes Nauvis to supply fusion fuel cells to the hub when the platform stock is insufficient. Meanwhile, other ships that should only obtain fusion fuel cells from platforms will instead supply fusion fuel cells to Nauvis, resulting in an unnecessary logistics loop.
Indeed, I can detect:
- Whether an Aquilo ship is docked at Nauvis;
Whether the ship has enough fusion fuel cells;
However, this solution is very complicated and unstable:
- The cargo on Aquilo ships is not necessarily all intended to supply the hub;
Excessive requests can still cause Nauvis to supply the hub in reverse;
Players need to create a large amount of additional circuit logic, while this control should ideally be provided directly by the logistics system.
Why?
The new inter-platform logistics system is a very exciting feature, but currently it is limited in complex situations because players cannot control the source and priority of requested items through signals.Buffer chests have use cases. Logistic chests already have buffer chests, and requester chests can choose whether to accept items from buffer chests. I think my suggestion may not require changing the fundamental game logic or gameplay.
