Blacklist filter on splitter

[Legendendear]

Hello there

does anyone here have an idea how hard it would be to modify splitters to allow a blacklist filter on splitters in general? (like with inserters)
Or if thats even possible at all? Or even if a current mod exists that does that?
I'd be willing to get my feet wet with lua modding depending on the difficulty of this task.

Just asking more experienced modders out there for directions on how to get started.


I am interested because this feature is what I need to keep my automatic asteroid upcycler neat and tidy.


Thanks for your time and answer in advance.

Feature Exists - it is the other output lane of a Vanilla Splitter; it will not have any of the specified Item in its output.

Sorry, bad communication from my side, am still learning accurate communication (a known character flaw I'm working on)

What I meant was (in your example) to allow all items through on the bottom side and all items on the top minus green circuits.



Here's what I'm trying to do:
A combined input and output belt for asteroid reprocessing.
The only problem I'm unable to solve is to prevent any epic quality (Dont have legend unlocked yet) asteroid from entering the dead end belt.

You can achieve that by Splitting the “Blacklist” side of the Output again, and then half recombining further downstream with the “Whitelist” side.



Or, try using a Quality Filter on a Splitter (supporting Equals, Less Than, etc) without an Item Filter, to sort out all of the less-than-Epic items.

Good luck!
