Hover ALT Mode

by Morlot

Shows the ALT mode icon for just the entity under your mouse cursor, while the ALT mode stays off. ALT mode no longer has to be permanent. Normal mode becomes a real alternative, without giving up what ALT mode tells you.

Changelog

Version: 0.21.15
Date: 28.08.2026
  Bugfixes:
    - Fixed a multiplayer desync. The mod asked the game whether a player had ALT mode on, and
      that is a display setting each machine keeps up to date only for its own player. Two
      machines could answer differently for the same player and draw differently, and the game
      came apart over it. The mod now keeps track of it itself. Thanks to haraldperson for the
      desync report
  Changes:
    - Loading an existing save with this version switches ALT mode off once, for everyone. What
      each machine believed before cannot be recovered, and off is the one value they are certain
      to agree on. A single keypress puts it back
Version: 0.21.14
Date: 27.08.2026
  Features:
    - Inserter, splitter and loader filters now show the quality they ask for the way ALT mode
      does. The comparator is written beside the badge, a filter that takes any quality gets the
      any quality symbol, and a filter that names a quality but no item is drawn as the badge
      alone at item size
Version: 0.20.14
Date: 27.08.2026
  Info:
    - Factorio 2.0 build of 0.21.14
Version: 0.21.13
Date: 25.08.2026
  Bugfixes:
    - Fixed a crash on hovering an entity whose prototype carries no flags at all. Thanks to
      haraldperson for reporting it
Version: 0.20.13
Date: 25.08.2026
  Info:
    - Factorio 2.0 build of 0.21.13
Version: 0.21.12
Date: 22.08.2026
  Features:
    - Added an automatic ALT mode, under a setting of its own and off by default. It switches the
      vanilla ALT mode on while a blueprint, a planner or a circuit wire is in hand, and off
      again when it leaves
  Bugfixes:
    - An entity whose prototype hides its own ALT mode info no longer shows its recipe, its
      modules or its contents on hover, the way ALT mode shows none of them on it.
Version: 0.20.12
Date: 22.08.2026
  Info:
    - Factorio 2.0 build of 0.21.12
Version: 0.21.11
Date: 20.08.2026
  Locale:
    - Added French, Spanish, Polish, Czech, Russian, Simplified Chinese, Japanese and Korean, next
      to the English and German that were there already
  Info:
    - Every language is AI translated. Each one is written with the wording vanilla Factorio uses
      itself, so an entity is called here what the game calls it. If something reads wrong in
      yours, please report it in the Discussion tab
Version: 0.20.11
Date: 20.08.2026
  Info:
    - Factorio 2.0 build of 0.21.11
Version: 0.21.10
Date: 19.08.2026
  Features:
    - Logistic and construction robots show what they are holding, on the robot and the way ALT
      mode draws it
    - A construction robot on a repair job shows its repair pack as well. Carrying both at once
      draws them overlapped on one spot, cargo on top, exactly as ALT mode stacks them
    - A cargo pod now shows its cargo while it climbs away from a planet too, which was the one
      place this mod deliberately drew less than ALT mode. Nothing is held back anywhere now
  Info:
    - Robots had been listed under "tried and dropped" since 0.21.4, for icons that ran ahead of a
      flying bot. That was this mod's own doing, not the engine's: a bot's selection box sits
      around where it is drawn, its position is where the logic has it, and holding one against
      the other handed a flying bot its movement prediction a second time
Version: 0.20.10
Date: 19.08.2026
  Info:
    - Factorio 2.0 build of 0.21.10
Version: 0.21.9
Date: 19.08.2026
  Features:
    - Added counts on item icons, under a setting of their own and off by default. ALT mode draws
      the icon and never says how much is behind it, so this is the second thing here it has no
      counterpart for anywhere
    - Turrets, artillery turrets and artillery wagons show how many rounds they are holding,
      written into the lower right corner of the ammo icon the way an inventory slot writes it
    - The number keeps up with the firing. It counts down as the turret shoots, without the icons
      underneath being taken down and drawn again for it
Version: 0.20.9
Date: 19.08.2026
  Info:
    - Factorio 2.0 build of 0.21.9
Version: 0.21.8
Date: 18.08.2026
  Features:
    - Plants show the quality they were grown from, in the same spot ALT mode marks it, wherever
      Quality Plants is there to remember it
    - Rocket silos show what has been loaded into the rocket, laid out the way a chest lays out
      its contents and in the place the silo draws its own icon
    - A chest a mod hides inside a building shows its contents on hover, where it stands and the
      way ALT mode draws it. Such a chest can never be pointed at, since the building around it
      wins the cursor every time. Contents from chests only: whatever else a mod hides in there
      keeps what it holds and what it crafts to itself
    - A machine a mod hides inside a building shows its fluid connections on hover: each fluid
      where its pipes dock, with the arrow the game draws beside it. Those arrows are not an ALT
      mode thing at all -- the game draws them on whatever the cursor picks out -- so a machine
      that cannot be picked out never got them. The recipe stays hidden, the way the mod meant it
    - Cargo pods show what they are carrying, laid out the way a chest lays out its contents. This
      is the pod on its way between a silo and the ground, not the one that has landed
    - A pod climbing away from a planet shows nothing, and has its icons back on the way down.
      No icon can hold onto something accelerating that hard, and it slides off ahead of the pod
      instead. ALT mode does show the cargo there, which makes this the one place this mod
      knowingly draws less. Leaving a space platform is not affected.
    - A cargo pod the player is riding in shows the figure instead, for as long as it stands
      waiting to launch. ALT mode drops the figure the moment it lifts off, and so does this
  Bugfixes:
    - A machine that crafts a recipe fixed by its prototype is no longer struck through when that
      recipe has not been researched. Nobody sets such a recipe and no research gates it, the
      machine crafts it either way, and ALT mode marks it nowhere. Seen on Equipment Gantry, whose
      recipe is deliberately left unresearchable
    - The captive biter spawner shows nothing on hover any more, the way ALT mode shows nothing
      on it. It keeps a recipe it deliberately never draws
    - Two entities from mods of their own show nothing on hover any more: the scrubber of Air
      Scrubbing, and the artificial hive of the Apia-Carnova system. Both prototypes switch their
      own ALT mode icon off, and this mod was drawing one where ALT mode draws none. The scrubber
      counts once for both mods that have it, Air Scrubber being the 2.1 fork of Air Scrubbing
  Info:
    - A plant cannot hold a quality of its own, so this needs another mod to both remember what
      was sown and offer it up over the interface asked for here. Quality Plants 1.0.2 and up
      does. A mod that brings quality to plants some other way cannot be read and shows nothing
    - A prototype can switch its own ALT mode icon off, and no mod can read that setting while the
      game runs. Such an entity has to be known here by name, so please report one that shows an
      icon on hover and none in ALT mode
Version: 0.20.8
Date: 18.08.2026
  Info:
    - Factorio 2.0 build of 0.21.8
Version: 0.21.7
Date: 17.08.2026
  Features:
    - Added power bars, under a setting of their own and off by default. This is the first thing
      the mod draws that ALT mode shows nowhere at all
    - An electric pole or a substation shows two bars: production on the left, demand on the right,
      the larger of them standing full and the other drawn to scale beside it
    - An accumulator shows one bar for its charge, standing in a fainter track of the same colour
      over the full height, so an empty one still reads as empty and still says red
  Bugfixes:
    - Pointing at a turret ghost no longer crashes the game. Its priority list was read slot by
      slot, and asking for a slot past the end of that list is an error rather than an empty
      answer, which every ghost holding fewer than four targets ran into. Thanks to ashlesss_
      for reporting it
  Info:
    - The power bars need Factorio 2.1. A mod cannot read the electric network on 2.0, so the
      2.0 build stays without them
Version: 0.20.7
Date: 17.08.2026
  Info:
    - Factorio 2.0 build of 0.21.7, carrying the turret ghost fix and none of the power bars
Version: 0.21.6
Date: 16.08.2026
  Features:
    - Added the two tile loader, showing its filters the way the one tile loader already did
    - Added agricultural towers, showing the modules they are fitted with
    - Added labs, showing the science packs they hold at the slots those sit in, gaps and all
    - Modded labs that lay out only their module row still show their packs, as ALT mode does
    - Agricultural towers show the seed they are planting, under the extra icons setting
    - Added modules on their way: planned into a ghost or requested into a machine already built,
      each in its own slot and under the delivery mark ALT mode puts on it
    - Added arithmetic and decider combinators, showing the signal going in above the middle of
      the building and the one coming out below it
    - An entity of better than normal quality is marked in its lower left corner, the way ALT mode
      marks it. This shows on anything at all, belts and walls included, and takes the ghost tint
      on a ghost
    - The extra icons setting gained a third state that keeps them showing while ALT mode is on,
      since ALT mode draws none of them and nothing can double up
  Modding:
    - The extra icons setting is a string setting now, under a new name. Whatever it was set to is
      lost, and it starts off again
  Bugfixes:
    - Constant combinator ghosts show their signals, which they should have done all along
  Changes:
    - Icon rows a prototype lays out itself are drawn at the size and spacing it asks for, which
      also fixes modded entities asking for a spacing of their own
    - Icons that sit at their own slot are no longer cut off after the first rows, and a single one
      of them stays small instead of standing in for the entity icon
Version: 0.20.6
Date: 16.08.2026
  Info:
    - Factorio 2.0 build of 0.21.6
    - Agricultural towers gained module slots in Factorio 2.1, so their module row
      needs 2.1 and only the seed below the tower shows on 2.0
Version: 0.21.5
Date: 16.08.2026
  Features:
    - Added turret target priorities, up to 4 icons in a row across the lower half of the turret
    - Gun, laser, flamethrower, rocket, tesla and railgun turrets show them, ghosts included
    - Added asteroid collectors, showing the chunks they are filtered to, up to 6 icons
    - Recipes that have not been researched yet are struck through, the way ALT mode marks them
  Changes:
    - Blacklist marks on filters are drawn at the size ALT mode gives them, a little smaller
Version: 0.20.5
Date: 16.08.2026
  Info:
    - Factorio 2.0 build of 0.21.5
Version: 0.21.4
Date: 15.08.2026
  Features:
    - Added a setting, off by default, for icons that ALT mode does not draw at all
    - Mining drills show what they are digging up, and follow the ore under the cursor on a mixed 
      patch
    - Pumpjacks show the fluid they bring up
    - Flamethrower turrets show the fluid they are loaded with
    - The big mining drill draws its icon at the size vanilla gives a building that large
  Changes:
    - Quality badges are drawn at the size ALT mode gives them, half the icon instead of a bit less
Version: 0.20.4
Date: 15.08.2026
  Info:
    - Factorio 2.0 build of 0.21.4
Version: 0.21.3
Date: 14.08.2026
  Features:
    - Added inserter filters, up to 4 icons like a chest
    - Added one tile loaders, filtered the same way as inserters
    - Added splitters and lane splitters, showing input and output priority
    - A splitter with an output filter shows the item in place of its output arrow
    - Filters on a blacklist are struck through, and one that passes nothing shows that mark alone
    - Ghosts show their filters and priorities, not just their recipe
  Changes:
    - Pumps show their filter instead of the fluid inside them
    - Icons on ghosts are drawn at full strength, only splitter arrows take the ghost tint
    - Icons follow at once when an entity is rotated or flipped
Version: 0.20.3
Date: 14.08.2026
  Info:
    - Factorio 2.0 build of 0.21.3

  Features:
    - Added cargo wagons, up to 4 icons in a row along the wagon
    - Added fluid wagons and artillery wagons
    - Added landed cargo pods, up to 4 icons like a chest
    - Icons on rolling stock turn with the wagon and stay on its body, in curves as well
  Changes:
    - Icon size and spacing now match ALT mode, which affects every entity type
    - Module rows on machines that need more than one row are placed like ALT mode
    - Chest and wagon contents are ordered by amount, the way ALT mode orders them
