Ah ok, the retriever is still cool for other future projects i have, but it doesn’t seem to say anything about pulling exact amounts of items.
In a perfect world, there would be a retriever cover that one can set to retrieve evenly divisible amounts of X with a oredict filter so i can have them pull to dust funnels of different sizes.
Or you know, a metapile of dust that automatically grows as any other size dust sits in the inventory with it. Lag city of course.
I mentioned this issue as a requested feature in mechaenetia. Having dynamically sized piles of stuff.
