an upgrade-recipe effect? unlock recipe-2 if/when recipe-1 is researched, and replace recipe-1 with recipe-2 where recipe-1 is being crafted?

Support for arbitrary locations for source code? Bitbucket, Gitlab, Sourceforge?

Some mods link to their source code via the 'homepage' url, which works, mostly, but if you want to link to a forum page _and_ your source code repository, it's not an ideal solution.

I believe that you can add an arbitrary icon to a dummy effect entry with an arbitrary localised string, so it's entirely possible to document to the player what is about to happen. Given that I perpetrated OR-Node s, I would like to be able to say that researching this technology also completes res...

on_technology_researched, unlock another technology; quite easily done already?

Good enough for me.

Thanks for looking into it. =)

What did you do? Started Factorio under the debugger to check to see if the mod I'm updating works as designed. Tried to resume the latest autosave. What happened? Factorio crashed to desktop. What did you expect to happen instead? Perhaps an error message of some sort saying that this chunk of Lua...

... Take all existing items and: Create an untested-<item> that has not been through quality control Create a failed-<item> that has failed quality control. ... mrudat's specification is, that for each <item> (eg car, icon: car ) an untested-<item> (eg untested-car, icon: car? ) and a failed-<item>...

Are any of the new settings (or settings in general) interactable with by mods? Eg. a mod that wants to show all possible items to the player, not just those that are unlocked? Or alternatively, a mod that wants to avoid a given fluid being deleted? eg. pollution stored in liquid form. Hmm. Perhaps ...

What did I do? Attempted to apply an update to a windows copy of Factorio 0.18.31 by running the following: C:\Program Files\Factorio\bin\x64\factorio.exe --apply-update core-win64-0.18.31-0.18.32-update.zip At the same time, I also have a mod enabled, that I'm developing, that doesn't load (yet). ...

The thought I had was that it would replace the vanilla tech tree; the higher up the tech tree the higher the starting chance of failure, and the more expensive the research, ideally balanced to be around the same amount of effort to complete as the original tech tree. Each technology would asymptot...

Here's some notes on a mod I'm contemplating making, just in case someone else thinks it's an awesome idea and implements it before I get a round tuit. Create a new "Quality Inspection" furnace-style entity (automatic recipe selection). Create a new "Rework Report" used to perfor...

Is this a horrible idea, now that we can run Factorio under a debugger? =) if mods['debugadapter'] then log("Creating " .. new_item_name) end Actually, would it be possible to do something like have a `debug_log` function that only gets turned on when Factorio has failed to load, and on th...

LuaEntityPrototype is the control-stage version of (for example) data.raw.locomotive. If you add a field in the data stage to data.raw.locomotive, eg: data.raw.locomotive.locomotive._MyModData = { --[[ Stuff my mod needs to know about locomotives ]] } That'll work, and you can read the data back lat...

Given that it's supposed to connect to nearby entities underground, I would have thought to animate tinted pulses going from the module out along the cables/ducts... presuming you pick the same tint as the socketed modules it should look pretty good, I'd think.

TL;DR Now that we can supply mipmap images for icons, would it make sense to change sprite definitions to use the same sort of format? What ? Extend sprite definitions to support supplying mipmap data in the same/similar format as icon definitions. Why ? Eventually, one less code-path to maintain.

I believe that minimum usage comes from energy_source_prototype.drain, which is by default, a fixed fraction of energy_usage. energy_usage and drain, I believe are expressed in terms of J/tick. So, an AM1, which has an energy_usage of 1250J/tick can consume 75kW of energy performing useful work, but...

I just posted https://mods.factorio.com/mod/OR-Nodes which addresses the problem of technology a depending on (say) plastic-bar, but plastic-bar is unlocked by technology 1 or technology 2. It creates a synthetic technology that represents "The ability to create a plastic bar", and unlocks...
