But the description says this modifiable. If it says "I consumed a Foo" and I modify it to "no, actually you consumed nothing", then it should have some effect, no? Perhaps I was overly optimistic about it returning the item, but there is no documentation on what this modifiable inventory does when ...

The 2.0 changelog says:


Changed on_built_entity event. Instead of stack/item, it passes consumed_items - modifiable stack of items used for the building.


Sounds great but I can't figure out how I'm supposed to use that. I am trying to "refund" the item used when placing the entity. Ideally the ...

Ah, I have a simpler idea that perhaps is easier to commit to.

Could you document/commit that when there is an event "X changed", then you cannot see the new value of X from Lua before the event has fired ? Put differently, which events are instant, no matter what causes them (Lua or the engine ...

Thanks, Bilka!


For events where there are ordering expectations they are documented on the lua actions that raise those events. E.g. https://lua-api.factorio.com/latest/classes/LuaControl.html#begin_crafting instantly raises on_pre_player_crafted_item and at some point in the current tick on ...

A single player action can create multiple events, for example on_player_cursor_stack_changed and on_player_main_inventory_changed. Could you document what to expect in mods about this order?

a. "No guarantees whatsoever": the events can be raised in a different order every time, even for the same ...

So I guess if it counts as "personal use" or "distributed as part of your mod" and not "commercial use", it's ok.

I'm not sure about github, but uploading your modified version of util.lua to the mod portal is ok according to that.


Personal "use" definitely doesn't cover distribution, but yes ...

Sorry, this isn't exactly a modding interface request.

I would like to propose that you license util.lua under a permissive license like MIT. This will enable mods to copy and modify (parts of it) freely, regardless of their license.

My use case:
I am working on a mod where most of the tests can ...

But if you don't want it to be auto placed, why do you need an AutoplaceControl? You can define the prototype and just place it with create_entity.

Proposal: add an optional size parameter to AutoplaceControl defaulting to true. When set to false, the "Size" slider in the map settings UI is removed (similar to how richness is optional).

Rationale: resources that are supposed to always spawn as a single node -- in that case would reduce user ...

+1 maybe now that raiguard is on the other side of the "fence"?

The relative gui system is so cool and it's so annoying to fall back to easily broken coordinate hacks

According to the StatelessVisualisation docs you can use it to make a light on an entity. There are no examples of this in base or space-age (that I can find) and no explanation in the docs on how that works. I'm trying to guess but it doesn't seem to be working. For instance adding this to a ...

The current documentation seems to suggest that the only case where it can be nil is if the entity is not a player. But in my testing, it's also nil if you're looking at the map/remote view. This is unexpected (intuitively, why would player.get_main_inventory() not work just because the player is ...

In my mod, I would like to react to a (custom) assembling-machine finishing a craft. As far as I can tell, there is no way to do this short of reading LuaEntity.crafting_progress or LuaEntity.products_finished on every tick. I was hoping for something better or more efficient.

This was requested a ...
