Warning: "this mod" = the mod i am suggestiong. I did not give it a name since whoever makes this mod will be the one who has the privilige to name it

Did you ever play with ...

You can already do this by rebalancing quality or faking quality.

No? That just changes the game speed...

Doesn't this already exist... twice?
Link to Space Block

There's also the 1.1 mod called Spaceblock - though it hasn't been updated to 2.0 yet so it probably isn't what you're looking for:

Can't you just reduce the amount of ingredients required? Basically, what's the difference between:

{ inputs = { "catalyst" = 10, ignored_by_consumption=true},
outputs = { "catalyst" = 5} }

and

{ inputs = { "catalyst" = 5},
outputs = { } }


I don't understand your argument... ignored_by ...

There are 4 main options available for you:

Use Quality.
Never play Factorio again. (not recommended)
Start a new save game.
Play an overhaul mod(s). (highly recommended)



I don't know much about Minecraft, so i may be wrong but i don't think the mod "redstone" that inspired factorio adds ...

I'd like to be able make a machine that takes in 2 items, a catalyst and another ingredient, then outputs 2 more items, the catalyst back and another result. However, at least in my case, it doesn't make sense for the machine to "output" the catalyst, rather for it to just stay in the input slot ...

This is a great idea - it would improve many mods that currently have to use a chest instead of a machine for various reasons. (in particular, having a million different recipes you want the machine to be able to perform) Though, I'd want to be able to make it furnace-like with more than 1 input ...

I think I actually saw the mod before you told us about it. : )
I certainly saw the mod before I read your message, of course.

The optimal space platform design is a rectangle and it can't have holes



Nope. I've recently been working a space platform that's less than 2 thrusters in horizontal width but has well over 2 thrusters in total.
It mostly looks rectangular, but it has very big gaps, since thrusters prevent ...

...and no. That mod completely removes the player character. What this person is looking for almost certainly is just to be able to deploy a roboport on new planets instead of players, not to remove the player entirely.

there is quality_affects_energy_usage for crafting machine but not for lab, furnace and I may miss some.

also Default: Value of default_multiplier would be must better than default to one


Furnaces inherit from crafting machines, as other people have pointed out, but labs and mining drills do ...

It's not related.

It makes sense that fluid temperature affects crafting speed by default, but I want to make a steam powered plant grower and harvester and it makes no sense for fluid temperature to affect how quickly plants grow. I searched the modding API for anything ...

Edit2: UI for the different slots would be a duplicate of the output slots, but with the wildcard quality icon on each possible output - or perhaps the recipe's "base quality" with a greater-than/less-than next to it. An additional advantage of this is that it could clearly communicate what ...

I'm wondering if you could take it a step further, and always have outputs that are of a different quality (relative to the "expected" quality) go into special "different quality" slots. So even in the base game, if a recipe's output is bumped up a quality, it will go into the special ...

When auto requests are enabled that’s exactly what the engine is doing.


Perhaps, but the native C++ code probably runs a lot faster than equivalent lua code, it would be simpler to code this kind of behaviour in lua and it would prevent the game from having to check every space platform twice ...

Proposed solution of "ignored_by_quality" being an integer has a fundamental flaw that makes it impossible to add: if a recipe would finish, due to value of this field it coukd happen that X items of better quality and Y items of original quality would be given but they would have to be both ...

I really like the SE spaceships, I just don't see how this could ever be implemented to work with SA instead of SE.
Cool idea, but probably not that feasible.
