Apparently the CircuitCondition struct table thing has a "fulfilled" property. Handy and entirely practical. See (https://forums.factorio.com/viewtopic.php?p=179527#p179527)

Unfortunately the API docs are missing this important tidbit of information. (http://lua-api.factorio.com/0.13.6/Concepts ...

Does CircuitCondition.fulfilled exist? it's not in the API. Good to know if it does.

I'm pretty certain your error is a misplaced bracket in your technology\natural-gas.lua file

I'll take a crack at helping. :) Though I'm afraid I haven't got a direct method.
Honestly, I'd request the enabled state be added to the mod API, as solving this the way I'm about to propose is a bit arduous and wasteful.

Combing through the Lua API (http://lua-api.factorio.com/) for version 0.13 ...

I've tried searching and not found the answer. It's probably dead obvious but I'm usually worst when things are. :P

I'm trying to essentially recreate the technology scroll frame. I've not decided if I want to use icons or not, but I definitely need to be able to scroll the list.
I've got a frame ...

Thanks for fixing all these things so quickly! You guys rock.

I love the changes, too. Nice improvements.

That was fast! Thanks!

In my per-player forces mod I'm working on I've got a feature which allows you to move the structures your force owns to another friendly force (while retaining ownership).
This works fine, for the most part.

However, in testing it today on a more progressed world I noted that my Logistics ...

I don't know if this is a bug or not. It did surprise me.

I would like to know more and do more with map charting. Specifically I'd like to be able to know when a force is actively charting a sector of the world and be able to draw things to the chart either at that time or later.

Suggested features:
An event (ex. on_surface_charted) which informs that a ...

1) In terms of accomplishing this without adding entities to the world, you could try a procedural method of calculating the resources at a location (example: Perlin Noise) which allows you to sample a region at will for little cost. Perlin noise is a good option as it's pretty close to a lookup ...

My mod if progressing nicely. :D This system is both well designed and fun to play with. That's not surprising, really, but worth mentioning. :)

For my next tasks I'd like to play more with the map, what can be seen, and how some things appear on it. I'll make multiple posts to keep things ...

Of course! That makes perfect sense. Thanks!

Thanks for the super quick support. I've been where you are in other contexts, so I send much support and respect to you.
And I absolutely love Factorio.

This is my first post, so I apologize if I didn't pick quite the right location for it.

Greetings! I'm starting to cut my teeth on Factorio modding. It's something I've been tempted to do a few times but up until now haven't touched on much. I have played with the in-game live scripting, which is ...
