Well it is documented. There's just no description of how it works, which is what I think you mean and want.

+1, while I prefer mine (127039), getting it in any form would be nice

I've seen a handful of mod bug reports where a player related event errors on a server, and people struggle to really explain what would have caused it because they aren't sure who caused it.

I'm proposing that for events related to a player (any that have a player_index), the ID and username of ...

Then this should be moved to Documentation Improvements so we can ask for that to be mentioned.
Something like:

Note: setting a non-zero value while it's zero will start a normal craft free of cost and irrespective of recipe quality. Set result_quality to have another quality result.


I'm not ...

I think I'm actively opposed to requiring categories. The vast majority of modders and recipes don't want anything other than the current default behavior (in my opinion).
I don't think modders currently even consider the category unless they specifically want something other than the default. As ...

I was under the impression that the latter of A was already going to happen (merging the fields).

And I do think I prefer a default of {"crafting"}. My question is, how would it behave if you were to give it {}?
I went and checked the machine, and it errors without any crafting categories, so I ...

It is listed as one of the main global objects on the prototype index

Not sure there's a good way to make them show up in the search..

If it can be made a "mode" type parameter where you can make it mark the replaced entity for deconstruction instead, then it could be manually destroyed without letting the user (or their bots) have a chance to actually mine it.

This would also be a possible fix for a bad bug I have in my mod that ...

I currently have a pretty bad bug in the mod Wide Containers . I previously tried 'fixing' one of the causes with a bug report: https://forums.factorio.com/130389
But it's been understandably deemed "not a bug".

Because the actual root of my issue was the LuaSurface::create_entity fast replace ...

It would require a big warning that they don't update until the inserters themselves update, otherwise I'm confident people would bug report it
(And some probably still will with it, but at just we can tap the sign)

As modder you can change recycling recipe generation yourself however you want.
It's not done in game engine, everything (except using specific recipe category) is done in lua.


While it is in Lua, it's not as if you can just change the code from another mod.
You can undo said changes, but we ...

I personally just wish we could somehow provide/change the second argument to this function call

That way if you want non-overwriting behavior you can just add it to your `can_recycle ...

I'm not sure where specific valid entries such as day-night-cycle, magnetic-field, solar-power, pressure, and gravity are documented in the API. Also, when looking at other modded planets, it seems possible to define additional attributes such as temperature, but I couldn’t find any mention that ...

Doesn't your given example describe what it takes?

It displays as dictionary[ SurfacePropertyID -> double ] for me
Meaning that the keys are SurfacePropertyID's with their values being ...

If you look at the "used in" of the CircuitConnectorDefinition , you see a long list of individual entities implementing the ability to connect a circuit to it.

My hope is to promote that to some baser entity type (probably EntityWithOwner ) so you can make just about any entity connectable to ...

Considering my understanding is that an entity "wakes up" the inserters around it, I would assume this information is already available in some form.

Don't know how convertible to an api field that is though

Maybe this should be moved to documentation improvements then?

I've gotten a bug report about my mod Biter Memoirs about our LuaRenderObjects showing up in fog of war. With a bit of investigating, I've found it's specifically the use_rich_text option that causes this.

Take this snippet of code, and then hover over an entity near the left edge of fog of war
You ...

As the title states, we cannot do custom tooltips on recipes when we can still do localized descriptions (the old method of custom tooltips)

Since it's on the Prototype I would've expected it to work on at least the major four (Items, Entities, Recipes, and Technologies).
I can concede it maybe not ...

Boskid recently gave pretty good detail about what exactly it means for an entity to be mirrored
I believe it should make it into the documentation


when i was un-messing the entity flipping logic and mirroring logic (and there as a lot of stuff to un-mess), i came up with following rule that ...
