Detecting when modules change can be done with the current modding API. Modules can only be changed by a player manually moving them, by item request proxies ("ghosts"), or by scripting.

For players manually placing/removing modules: a player can only change modules for an entity if it's their ...

Here's my proposal for how exactly this could be done:

We add a modifiers property to the quality prototype of the type dictionary[string -> dictionary[string -> Struct]] where the Struct has a type property of the type "additive"|"multiplicative" and a value property of the type double .

The ...

Why wasn't the character limit on the forums mentioned? You obviously seemed to have a problem with posting the changelog here, as you wouldn't have had to split it into one long post and an even longer post otherwise.

On that note... why was the first post shorter than the second?

Where does it say that `hidden` is a string? https://lua-api.factorio.com/2.1.7/prototypes/PrototypeBase.html#hidden clearly shows it as being boolean.


I'm talking about the requires_ingredients_to_unlock_results property, which is a boolean as described on the page, but with a default value of ...

On the 2.1 docs, for the new property requires_ingredients_to_unlock_results , the recipe prototype page says that it's of type boolean yet the page also says that it has a default value of "Value of hidden ". This doesn't make sense, as the boolean and string types are generally considered to be ...

On the 2.1 version of the docs, some links appear to have gotten coloured blue/green/a different orange for links that go from one section of the docs to another. (e.g. prototype docs to auxiliary docs) I personally don't like this change and would like a way to either revert the colours to the ...

The Thruster type entity is highly controlled by the Space Platform behavior and LuaEntity attribute active is not enough to have full control over the thrusters.
Using active attribute constantly makes it so that it flickers between the two states every tick

The use case for this is that ...

Can you not just destroy the rail ends, request the path and then put them back?

I think what you are looking for is Lane Balancers mod:
https://mods.factorio.com/mod/lane-balancers
(It does not even have control.lua, making it entirely scriptless)


I don't think you read the original post. It's nothing like what we're looking for, since it only swaps the 2 lanes if both ...

They're probably expecting the english localisation for the "Single player" button to say "Singleplayer", or the localisation for the "Multiplayer" button to say "Multi player", so that it's consistent.

I think you're a bit late... like almost 2 years late...

This is not going to happen because mods are stored as zips in mods directory and windows being case insensitive would cause file name conflicts if there were 2 files to be put in the same directory that only differ in character cases, for example if someone had a Lightorio_1.0.0.zip and lightorio ...

I've been creating a mod called "Lightorio" (that's the internal name, btw) but the mod portal won't let me upload the mod, with the error "Mod with that name already exists." Even though I checked before I even started making the mod that the internal name wasn't already used by another mod. So, I ...

I don't want my recipe and item to be separated into 2 different pages on factoriopedia, when it only needs to be one page, regardless of what I choose to name the recipe internally.
Maybe a main_recipe property on an item mirroring the main_product property of a recipe. This could even be used ...

a non-fluid recipe validates the "no fluid recipe" requirement because its not a fluid recipe. perhaps instead it should be fluid_boxes_always_on?


Yeah, but it acts as if the fluid part isn't there. When false , it only shows the fluid boxes when there isn't a recipe or when the recipe uses the ...

I can see how this might be difficult for the developers to implement, though.

Currently, I'm working on a mod where certain types of recipes have effects in-world. (creating/destroying/modifying entities)
One of these changes depending on the rotation of the machine - for one particular machine, which currently is using the placeholder graphics of an assembling machine 2, I ...

I expected the property to allow me to have fluid boxes always display, which is what I want - not whatever this fluid_boxes_off_when_no_fluid_recipe thing is.
