Factorio Forums

Hello fellow Factorians,

I was wondering if a small addition to the splitter is possible. I use the splitter filter function a lot to get specific items from mixed belts but it takes quite a lot of tiles to put them back on. A toggle option like the one in the attached screenshot would make my factorio setup a lot cleaner, easier and prettier. I spend quite some time staring at some similar LUA codes but it's still too challenging to find the solution myself atm.

Wouldn't that be enough ? it does require extra tiles, but quite few, you double the number of splitter though.

I use this a lot but without the output priority on the first splitter.

Here's a more sophisticated application. I have a 'rainbow' belt on which I put a lot of different items.
Upstream I only put items on the belt if they are needed downstream.
I create a 'request signal' based on chest inventory downstream. The 'Belt sorter' mod has some features to do this, but I don't like the way items disappear and appear using these sorters. A small mod to the Vanilla splitter would be much preferred.

Searching for a solution once again, but there just isn't an option to change splitter behaviour, is there?

Doesn't work with a 'rainbow' belt containing mixed contents.

Edits, thinking out loud:
What if the splitter 'filter' is temporarily set to a placeholder (i.e. fish) in case the output belt is saturated. That would mimic the desired behaviour quite a bit...

If !can_insert_at(filtered_output_position) Then splitter_filter=placeholderLuaItemPrototype Else splitter_filter=OriginalLuaItemPrototype

Forum post: Circuit network connections for splitters.
If the filter condition would be programmable it would be managable as well (with a lot of circuit magic)
