About Efficiency Checker Mod
From ficsit.appSee if your production is underflowing! Now with a hand tool, too!
See if your production is under-flowing!
Code has been refactored for better internal maintenance. Please let me know if something isn't working like it used to
ATTENTION: this mod is not compatible with Refined Power and other mods with custom machines that does not implement Attachments (like Splitters/Mergers), "Factories" (the ones that use recipes to consume and produce something), standard "Generators" or standard "Extractors". Any checker placed on belts or pipes connecting to those buildings will ignore their existence. A solution may come to some of those, but each case must be approached one by one, and that takes time
This mod allows you to verify if your production can work at 100% efficiency or if it is on risk of under-flowing, either because:
- You don't have the correct set of conveyors capable to deliver the minimum amount of required items;
- You are not producing enough items to deliver.
It is Multiplayer compatible. Many thanks to TwoTwoEleven (Micro Manage) for the orientations on how to get it working 😀

This mod is completely free. But if you wish to donate a value as a “thank you”, feel free to click on the button below.

What it includes:
- Two building for SOLIDS which you can snap on existing belts (or have a belt passing through it). One with panels on each side; the other with panel on top of it. They can be stacked on top of each other. Both will show you:
- The maximum amount of items/minute the producers can inject into the belts (miners, constructors, foundries, etc. Modded producers should work as well). You can manually change this number, if you find it necessary;
- The maximum amount of items/minute your belts can transport. This takes into account not only the belt it is connected to, but also connected belts/lifts preceding or following the current one;
- The required amount of items/minute your consumers need to receive to be able to work at 100%. You can manually change this number, if you find it necessary
- A wall variant for solids which you can snap to Foundation Wall Poles. It works the same as the stackable buildings, showing the information for whichever belt/lift is connected or passing through the Wall Conveyor Pole
- A building for LIQUIDS which can snap on existing pipes. Different from the solid ones, the pipe MUST connect to it, if you don't place it directly on a pipe. It can be stacked with other Liquids Checker or any of the Solid Checkers
- A wall variant for liquids which you can snap to Walls, just like a pipe wall adapter. It also includes its own adapter and snaps the same as a regular pipe wall adapter would. It works the same as the previous buildings, showing the information for whichever pipe connected with it
- A hand tool that can give you the same stats, realtime. Just point to a pipe, belt or lift, and click: the tool display will show the computed stats for the given belt/pipe. And yes, it IS expensive. You didn't though having an easy life would be cheap, right?
- Color coding:
- Blue: the field has a custom set, defined manually;
- Green: the inject input and/or the throughput limit is the same value of the required output (if the required output is greater than zero). All three fields will be presented with green color if the required output equals the injected output and they era less or equal than the throughput limit
- Yellow: The inject input is greater than the belt throughput limit;
- Red: the inject input and/or the throughput limit is less than the required output
- Black: injected input and/or throughput limit is greater than the required output. Indicates you still have room to increase the consumption of items
How do I get it:
It will become available to be unlocked at the hub once you have unlocked the Logistics Mk.3 milestone. The Hand Tool will be available at Tier 5
How can I build it:
Ground/floor checkers, for solid items
Method 1:
Just snap it into an existing belt. It snaps along any belt, much like how you can do with a splitter or a merger.Method 2:
Place the building down and snap the belts to it. It acts like a conveyor pole, so you can snap from either direction, with any orientation. You can snap above other EfficiencyChecker Buildings, too, but only if they are not inclinedMethod 3:
You don't even need to snap any belt to it. It will detect the one that is already passing through it. So,place it down, and just run the belt through itWall checkers, for solid items
Snap it to a Wall Conveyor Pole, no mather if it already has belts/lifts connected or notHighlights
