Version tested: 0.15.0 Standalone Steps to reproduce: Load this save https://www.dropbox.com/s/tb41dqmb63vsujr/fromtut.zip?dl=1 Start the first in-game tutorial Wait for the mining drill sounds to fade out Exit the tutorial through the escape menu Observe the drills and furnaces are silent Hitting e...

Reshade has a "Daltonize" filter with settings for Protanopia, Deuteranopia and Tritanopia. It's a game-agnostic colour adjust filter so it might not be of sufficient benefit to Factorio but it's easy enough to try to see if it's helpful to you. https://i.gyazo.com/321e8cfcb2de7e235a4da72...

When using script created unit groups and the members of the group are killed while carrying out a command, the number of unit groups does not appear to decrease according to show_detailed_info. This scenario recreates the issue I'm seeing - each group remains valid even after the biter is killed by...

Starting a script only scenario (i.e. control.lua but no blueprint.dat) in single player results in getting to specify the mapgen settings. However, this option is not available when starting the game from the "Custom Scenario" option in the multiplayer menu, instead you go straight to the...

If you add non-virtual signals to the signal_to_color_mapping table, e.g.: table.insert(data.raw.lamp["small-lamp"].signal_to_color_mapping, {signal="iron-ore", color={r=0,g=0.25,b=0.5,a=0.75}}) You get the following runtime error during the "Building prototypes" stage:...

Version tested: 0.14.21 Summary: Unknown sprite path errors from the Sprite GUIElement when created during the on_player_created event are reported with an OS message box followed by exiting the entire game. https://i.gyazo.com/bcd919d9ebd43a6fa839906a2c01b215.png Expected: It would be preferable if...

First up, this is really cool (and difficult!) and I'd love to see more mini-games like this to go alongside the main freeplay game. Give the player two stacks of each available item at the start of the level. (saves some clicks) Run the levels faster by increasing game.speed, like how "Tight s...

Any chance you could link some code samples showing the concepts you're talking about? I'm curious where it fits into the concepts of data parallelism and task parallelism . For example this: A clock is simply some point at which you say "I am done, here is my result", except that everythi...

Idea is to allow mods to define their own interfaces when a player clicks on modded entities, rather than having to clutter up the player's top level UI. Off the top of my head, something like this in data.lua: data:extend({ .... operate_ui = "my_entity_ui" }) And then define the function ...

Thanks, yeah, the example was just the bare minimum to do "something" with the result.

My understanding of the documented behaviour is that this snippet should work: script.on_event(defines.events.on_tick, function() end); game.print(tostring(game.get_event_handler(defines.events.on_tick))) Instead, you get the error "Unknown custom input name: 0" thrown (the 0 comes from va...

The main things I'd like to do with a map editor console are: Custom scripts for tile and entity placement Setting properties of multiple entities Although I suspect it'd expand into "pretty much anything you can do with a LuaSurface". I am able to do these things indirectly by starting th...

Version tested: 0.14.21 Summary: Land mines created on the "enemy" force are still visible on the map (and minimap) despite being invisible to the player's normal view. This happens with both mines set up as being enemy owned as part of a scenario or when created at runtime, such as /c gam...

Version tested: 0.14.21 Steam (also checked 0.14.21 Standalone) Symptom: Factorio crashes when running map2scenario on a save game created from a scenario created in the editor. Conversion appears to successfully complete despite the crash. Steps to repro: Download and unpack this scenario . Create ...

How complete is the sprite atlas caching feature intended to be? e.g. it doesn't seem to properly cache if you enable treemips or filtering (see timing in my logs), but it seems like a useful thing for normal users to have on.

Searched (e.g. "chain signal icon" "chain-signal icon") but didn't find anything related. The icon for the normal rail signal has two lights but the in-game object has three lights. Meanwhile the icon for the chain signal has three lights but the in-game object has one light. Thi...

While getting my head around the modding functionality of Factorio, I couldn't help but notice just how punishing a full restart of the game can be even with an SSD, so I had a look to see if there were any options that would speed things up (e.g. lowering texture quality etc.). I can't remember if ...

I recently wanted to make a custom combinator and couldn't find a way to declare it in my data.lua without copy/pasting a bunch of values from the game's code when I only want to change the bare minimum. Furthermore, I wanted to add my new item to the existing tech tree, again without wanting to cop...
