What

Like Decider Combinator, without AND/OR logic, with one signal output per row. Check the screenshot.

UPS friendly

All circuit logic is handled by vanilla combinators, invisibly. No script runs on each tick or update. There's no faster way.

Why

I use this mod to threshold-filter selected signals. In other words, translate raw factory signals into "what do I need more of, and how much more?"

I'm sure you'll find other uses.

Cost / complexity

1 new recipe, 1 new item, 1 new entity with UI. A little scripting on copy/paste and game load. Everything's as tight as it can be.

Blueprints, copy/paste, rotation, flip all work.

Competition

Lua Combinator allows MUCH more complex logic, but the UPS hit can be serious.

Pythonator leaves me with similar UPS concerns.

Note

The right click functionality is too hidden. To switch between signal count UI and a constant number UI, right click. There are 4 places to right click on normal rows.
