I started playing around with this idea;

Maybe I might pursue this

Additionally I see that technology "space-platform" has a trigger "create-space-platform" which is also not mentioned in the docs. Analyzing the data in game it appears that the research trigger only has a type and no additional properties. Looking at the research itself it appears that it uses the ...

Following the docs: https://lua-api.factorio.com/stable/con ... igger.html

"craft-item" only has members 'item" and "item_quality", but in-game I also get "count"

..that's this exact thread

When defining a TechnologyPrototype with both a research_trigger and a cost then the technology screen shows the icons from both parameters, but only the research_trigger is used to unlock the technology.

Used code:
data:extend({{
type = "technology",
name = "foo-train",
icon = "__base ...

For the mod that I am developing I want to unlock a technology on killing a certain enemy. Unfortunately there is no "on entity destroyed" trigger but I managed to implement this via scripting. However every technology requires either a trigger unlock or a cost, and both of them does not quite ...

Well let's just say I have a.. rather peculiar.. mod idea, where I have a train that has overlapping carriages. Due to the game's rendering engine (from left to right and from top to bottom) this train is rendered properly when facing towards the right, but messes up when facing towards the left ...

I have been fiddling with this in 1.1: https://mods.factorio.com/mod/train-bottleneck

Though due to time constraints I'm not sure if it will ever be ported to 2.0, so if someone is up to the vhallenge feel free to get inspired!

What did you do?
Running Factorio with only one single mod with only following script

-- control.lua
script.on_event(defines.events.on_research_queued, function(e) -- Also tested with on_research_moved, on_research_cancelled
game.print("On_research_ by player: " .. serpent.line(e.player_index ...

+1! I see so many mods which use arrow buttons that could benefit from this functionality, and with the 2.0 updates it just feels a lot more integrated.

Not a drone but has the functionality to scan indefinitely beyond regular boundaries: Infinite Radar

When a shortcut.toggleable is not set the shortcut's visual toggle behavior gives inconsistent results.

Observed behavior:
Given below code, player.set_shortcut_toggled gives inconsistent results depending on when a shortcut button is pressed or when a custom input is given to call a generic ...

Alright so I solved it. Apparently this element needs to be styled properly and doesn't work out of the box. Here's what I did;

Data.lua
local styles = data.raw["gui-style"].default

styles["my_camera_style"] = {
type = "camera_style",
horizontally_stretchable = "on",
vertically_stretchable ...

Hi there,

I'm having trouble to get a "camera" GUI element on my frame. I have tried literally everything up until the point that I disabled all my mods and created a new test mod with only the mandatory info.json and following control.lua:
script.on_init(function()
--Create a global variable to ...

Adding my +1 here too! Personally I never store blueprints in game (character, chest, entity, whatever) but always in my personal blueprint library. Almost all blueprint altering mods will benefit from this feature.

I feel so stupid now..
Thanks for this insight!

With 'no matter what item I select' I mean any item, being it a dumb stick to a rocket silo, selection tool, cusom mod items, you name it.

So I'm probably the gazillionth person trying to read blueprints from libraries and dove into the API docs to find player.is_cursor_blueprint and player.cursor_stack.is_blueprint, which should return a true/false whether the player is holding a blueprint item.

Now I tried and tested a million ...
