Thanks Rseding, that makes sense but I still feel like this is very unintuitive behaviour when one of the merged 'trains' is just a cargo wagon.
In my mind, the locomotive is the thing with a schedule and the wagons are just boxes on wheels, so placing down a box on wheels and it then overwriting ...

Manually connecting rolling stock in a locomotive resets the locomotive's group and removes some or all stops from the schedule.

Steps to reproduce:
- place some cargo wagons
- place a locomotive unconnected to the wagons and give it some stops
- get in the train and connect the wagons by pressing ...

TL;DR
Add circuit network connections for labs that reads the cost of the currently researching technology.

Avoid overproduction

Avoid spoilage
Request science as needed


What ?
When a lab is connected to a circuit network, it outputs the cost of the current technology - e.g. if I am ...

Suggestion for buildings the Demolisher should attack - now there are new pollution types, Vulcanus could have a 'noise' pollution value for each building, with the Demolisher only going after noisy buildings.

This would also mean a player could see from the map when structures are vulnerable to ...

That's what I was thinking, although the issue seems more like a bug than a modding issue.

I'm not sure if this is in the right place, but it doesn't seem like it was intentional.
While testing a modded gun that shoots projectiles similar to those produced by the shotgun, the projectiles often get fired behind the player, in the opposite direction to the majority of the other projectiles ...

That's disappointing. Why is this not possible?
The next step would be to ask how to access key binding information in game, presumably the data is there somewhere

I want to access config.ini in Factorio's user data directory. I have a Lua library that reads the .ini file, but I don't know what file path to use to get to config, as this requires going up two levels to the user data directory and then to config/config.ini.
How would I achieve this? I use ...

That's what I thought, my question referred to the function being evaluated each time the property is accessed, rather than once when all the prototypes are created.
Thanks for clearing this up!

I'm going to guess that setting the property of a prototype as a function to be determined at runtime is not possible, like this:


{
type = "item",
name = "an-item",
icon = "__modmodmod__/graphics/icons/thing.png",
stack_size = some_function()
}


As I said, I don't think this will work but ...

I have been industriously carpeting my super-base in concrete, and it is irritating beyond belief that you can't place concrete or any other path within three tiles of water. Does anyone know how I can rid myself of the ugly bands of normal ground bordering every patch of water near me before I go ...

Thanks, defines.inventory does pretty much exactly what I was after.
On a slightly unrelated note, is there any event that is called when a stack of items is manipulated? I really really don't want to have to use defines.events.on_tick

I am looking for some help on how to tell if a stack of ammo is in an inventory, or in the weapon quickbar, and also if it is in the weapon quickbar what the prototype of the weapon it is attached to is. An example example of what I would like to be able to achieve is that I would like to be able to ...

Thanks for the pointer, it was very helpful. I wish I'd known about http://lua-api.factorio.com/0.12.29/index.html before!
However, I'm still having some trouble that I could use some direction on. I have (considerably) modified the code, it now looks like this:

script.on_event(defines.events.on ...

I am trying to make a new ore glow by adding an invisible rail signal behind it when the game generates it, but i am having difficulty with the Lua script to spawn these in. It has been ages since I did any Lua coding, and at some point all the event have been totally overhauled and I no longer have ...

Sorry for the late reply, I have not checked the forums for a long time!
The mod is no longer being worked on, so you are free to use the graphics for whatever you want.
Thanks again to YuokiTani for his effort

Vulcan

I have made a Spitfire plane as a mod, but the entity rotates twice as fast as its image, like this -
plane-graphics.gif
The sheet looks like this -
spitfire-sheet.gif
The code is as follows -
{
type = "car",
name = "spitfire",
icon = "__Advanced Chemistry__/graphics/icons/spitfire.png ...

Thanks, that saves a headache!

How does the color system for fluids work? I want to know how to tell what color a combination of r, g and b will be without having to restart the game each time. Does it relate to normal RGB colour or is a variation unique to Factorio?

I do not think that anyone has posted this bug already, but when a construction robot replaces a destroyed turret the replacement cannot be damaged - see the picture.
I have tested this on a number of buildings and it is only true for turrets - this includes vanilla laser turrets and gun turrets ...
