If you really need to keep scan code processing, can we at least please have some config file option (or better yet, a menu item), to specify which scancodes are treated as which modifiers? I'm guessing the same issue will happen if someone remaps their Alt or Shift keys.

Issues to solve: Handle remapped modifier keys. and if you map some non-modifier key as extra modifier (eg. you map Caps Lock as the third Control), it won't work. So here we are, nearly 4 years after this issue was reported by the developers themselves after introducing it by themselves, and it's ...

I would like to know the precise positions of items held by a transport belt's lane. I couldn't find any appropriate method in LuaTransportLine, except can_insert_at(), which is a very indirect way of finding where the items might be placed. It also doesn't say what items there are. Using the LuaTra...

Hi, I'm looking for a comprehensive explanation of the pick-up algorithm (i.e. how do inserters decide which lanes to pick things up from, when do they switch the lane during pick-up and why, and what's causing them to slow down and why). I think the current behaviour is slightly crazy: when a belt ...

It turns out that a stack inserter with a stack limit of 11 fills up a chest faster than one with a stack limit of 12 when picking items from a fully compressed belt (with both lanes full). I don't think that should be the case. Can someone explain why this happens? Is it a bug or a feature? Here's ...

Furnaces seem immune from this issue as they only have 2 slots, so Eff3s will actually (probably) always make sense in them. Eff3 as far as I can tell -never- makes sense Ahh yes, of course, it's much better to put Eff2 in furnaces than Eff3. What I meant there by "always makes sense" was...

Nope! If you use prod3 modules in buildings, then adding beacons does improve energy efficiency. EDIT: sometimes.

OK, but can you please let me know what's the actual power it's consuming? I'm doing some other calculations that rely on this. Thanks!

The wiki at https://wiki.factorio.com/Beacon#Limitations says that Assembling Machine 1s should be affected by Beacons, however that's not the case. Has it been changed? If so, in what version? I can't seem to find it in the changelog. There is a slight indication that it maybe should or used to wor...

I call floor(41.999) an "improper rounding" of that number :-) Especially when the result is 41.9. That's definitely incorrect, even for a floor :-)

you can save some power by efficiency beaconing the rocket silo. Surprising, but true! I've done some analysis: Case 1: You're going for efficiency only, don't care about resource usage (really?): the most power-efficient setup is 3x eff3s, 1x spd3 in the rocket silo and no beacons Case 2: You're p...

What's more bizarre, is that the game is perfectly capable of displaying fractions there, BUT DISPLAYS THEM WRONG! For instance if you max out Efficiency modules to get the -80% energy bonus, the game shows "41.9 kW", instead of 210 * 20% = 42! This particular example smells like it's tryi...

Actually, another place where using eff3 modules can make sense is for assemblers 3 which are producing recipes which cannot use productivity modules. It appears you get the highest efficiency when using 3x eff3 + 1x speed3 and no beacons. But there may exist an even better setup, I haven't actually...

Hi, I wanted to point out an assembler 3 with 2x speed3 modules is showing up energy consumption of 504 kW (correctly), but as soon as you add a 3rd speed3 module (or more), it seems to lose a kW. With 3x speed3 it should be using 210 * (1 + 3 * 70%) = 651 kW, but the info box (shown when you hover ...

Here you are with a topic about furnaces (electric vs steel), and the benefits of Eff modules, wrapped in a poll : https://forums.factorio.com/viewtopic.php?f=5&t=51805. Oh wow, yeah, that's a great example of Efficiencies being sometimes useful. Electric furnaces don't actually work with my ex...

Agreed, the "intermediate products" are now quite confusing. They have their own "Tab" in the item list, implying all items there should be "intermediate", but not all of them are. The "can only be used in other recipes" definition is not quite correct either,...

Also, with the new nuclear plants, power is not a problem, so I ignore the efficiency modules. I thought about it a bit: https://forums.factorio.com/viewtopic.php?f=16&t=59989 . It turns out, if power or pollution IS a problem, then Efficiency modules are sometimes actually worse than Speed one...

Furnaces seem immune from this issue as they only have 2 slots, so Eff3s will actually (probably) always make sense in them. Nothing above an Eff1 module makes sense. I meant specifically that adding an Eff module to a Furnace will (probably) always make it more efficient than adding a Speed module...

Actually the "3rd or 4th Efficiency module" part of my post is not quite true either - it is OK when you have a building with 3 slots and have 2 Prod3s in it, but if you have a 4-slot building such as Assem3 with only 2 Prod3s, and want to increase efficiency, then adding 2 Eff3s look bett...
