unloading priority / filter of space platforms

[god bless you]

I would like to have to kinds of controls on space platform.

• Filtering items which can be unloaded in platform hub. Others will not be able to be unload.
  
• There are iron ores on both platform A and B. I hope that I can do unloading in sequence. A first, then B. Like what we do on trains.

Any ideas?

You can set filters on inserters so they only move specific goods.

For your second question, you can connect a wire to an inserter and tell it to "Set filters." Use a constant combinator to give it one signal and then use a combinator that says if the first signal equals 0 then output Signal 2.

inventory size of all my platforms are over 2k.
I can not hold so many items outside the hub.

second question is a problem cross platform signal problem.
I don't understand what you said.

Oh I see what you meant for your second question. No, platforms can't talk to each other. I would just send everything down to the planet and if that's too much, then discard it on the platform.

Every item has an internal associated ID number. In your personal inventory the items are sorted by that number. Knowing those internal numbers lets you use them as additional filters.

Kitch gives examples in his video. Starts at 10:35

Video is from 1.1 but the process still works.

Agree that being able to tell a platform to not drop a specific resource even if the landing pad is requesting it would be definitely be nice.

You can do that by adding that item as a request an setting the request amount to zero. Use multiple request groups if that item needs to be requested on multiple planets.

I would like to request iron from platform A, copper on platform B at the same time.
And platform A should not unloading copper, platform B should not unloading iron.
This is what I mentioned "filtering"

Currently, I don't see any way can do it well.

Hmm, is space its own "surface"? Perhaps each platform is its own surface.

If it is the former then you can try using radars to send signals to other platforms.

It might be broken down even more though such that "above navius" is its own surface.

Anyway here is the FFF about it.

Puncrathod answered that question. Set a request for zero copper from the planet on platform A and set a request for zero iron from the planet on platform B.

This is not correct.
The landing pad do need both items.
Just one more point is item A only from platform A and item B only from platform B.
So it is filtering.
It is not just a simple check box that enable / disable unloading in platform hub.

You seem to have misunderstood. I responded to someone asking for how to tell a platform to not drop a specified item. And the method I responded with is correct.

If you set item B as a request set to 0 on platform A then platform A can't drop item B. Just be sure to set the correct planet in the import from box.

so you are not taking about my questions.
sorry.

Glad you brought that up!
But further more I wonder if we can somehow, for example:
Keep 500 calcite on the space platform, but allow the redundant calcite to be requested by the cargo landing pad?
Because if I set calcite request on space platform to 0 like you mentioned, it won't drop any calcite.

It is the answer to your question, you need to play around with those options more.
Setting the requests properly *on the platform* will either prevent or force that platform from dropping material.
The idea is to set those requests up so you have your copper platform pushing the copper to the landing pad, and the iron platform pushing the iron to the landing pad, not just the landing pad pulling them from all platforms.

I don't think that having a planet request resources that are over a certain limit is possible.

But you can use the requesting system on the platform to make the platform chuck anything over 500 into the planet it is orbiting. The request amount slider has two components. If you set the max of the request to 500 then it will throw anything over that onto the planet even if the planet is not requesting it. This has the downside that the platform will keep sending the stuff even if the planet does not need it. You will probably want to setup the landing pads in a way that it won't get completely filled with the stuff blocking the drop of all other items.
