Factorio Forums

Suppose you have a set of machines, to which you've added modules and surrounded by beacons. Assuming you can feed and take away input and output items from the machines as fast as possible, how can you calculate the maximum rate of items used and produced? You can look at the individual machine rates and production bonuses, and do some math, or you can use this mod.

The mod provides a selection tool (default hotkey is ctrl-n), which when used to select a set of machines, calculates the maximum possible rate of items consumed and produced by those machines. These rates are displayed in a GUI window on the left side of the Factorio window, in various rate units. Items which appear as both inputs and outputs have net change calculation shown as well. (Does not calculate actual rates.)

Includes module and beacon effects. It's not necessary to select the beacons, just the machines affected by them. Probably will not work with mods that add new beacon types.

For centrifuging uranium ore, it approximates the output, based on the probability and quantity range of results.

So, to use: Press <ctrl>-n, and you'll get a blue question mark cursor. Select one or more machines, and you'll see the rates in the upper left. The rates are shown in items per minute, but you can select a different rate unit in the dropdown, e.g. Express Transport Belts - and see the number of these belts needed to feed the machine.

0.17 support. Turned off mining calcs. Guessed at belt rates. Number need verification.

Added locale string for the calculator toggle button

Added in-game four function calculator, accessed via game-configurable hotkey (default is CONTROL-ENTER, which toggles the calculator) or toggle button on Max Rate Calculator window. If you click on a value in the Max Rate Calculator window, it puts it into the calculator.

Fix for bug introduced in 1.2.10

Should work with modded beacons

Use newly-surfaced LuaEntityPrototype::fluid_capacity and distribution_effectivity rather than hardcoded values

Adds vertical scroll bars if there are many items to display. Items are sorted alphabetically. Rates for fluids are not shown for nonsensical rate units such as transport belts, or inserters. Added unit rates for train wagons per minute and per hour to the Rate dropdown list.

Adds calculations in terms of inserters. Tooltip on item icons shows num of machines using/producing the item in the selection.

Fix red belt calculation. Add warning if assemblers/furnaces have no recipe.

Dropdown list lets user select rate units. Rate per machine and surplus/deficit number of machines calculated.

Calculates production/consumption for furnaces (but not fuel). Beacon effectivity no longer hardcoded

Fixed calculation bug when mixed set of modules in an assembler

Fixed default hotkey (CONTROL-N not CTRL-N). Fixed en locale strings

Initial version, shows rates in items/sec and items/min, only handles assemblers, chemical plants, refineries, centrifuges
