I apologize in advance, but this would be a great usecase for triggering events by clicking on [shortcut=...] links in chat/factoriopedia while not cluttering the shortcut bar:

What did you do
- Create a shortcut with hidden = true

data:extend{ {
type = "shortcut ...

Sure, here is a very simple mod that explains the behaviour:
The point is that the second rule is meant to prevent the building from being placed on land, but AM3 can still be placed on land:

-- data.lua
local am2 = data.raw["assembling-machine"]["assembling-machine-2"]
local am3 = data.raw ...

Scenario: Two mods add a tile_buildability rule. One for whitelisting and one for blacklisting. (In this specific case, Maraxsis and Rabbasca).

Observed behaviour:
If all tiles of the two rules overlap, the second rule is discarded.

Consider these two buildings:

Rocket silo inventory size now scales dynamically with contents, so I believe for the first time the contents of an insert_plan for an item-request-proxy can point at non-existant indices. You can have a rocket silo look like this:

and bots will happily fill ...

What did you do?
delivered items to an assembler via construction bots, then changed my mind and placed removal orders, then changed recipe.

What happened?
Game crashed. stack trace below, full log attached ...

Create a mod that adds the following command and execute it twice:

commands.add_command("test_game_crash", nil, function(command)
-- NOTE: Does not crash and removes the item-on-ground if transfer_from_stack is called immediately after entity creation
local buggy = game.surfaces["nauvis"].find ...

Since we now have recommended dependencies it would be great if there is a way to have an option to make them load order independent. Right now those are exclusive options.
Given mod a and an optional addon a++ , it would be great if a could recommend a++ , but since a++ is an extension, it wants to ...

After looking at this for a few hours the only ways I found to unlock something as "researched" in factoriopedia are:
- for items and recipes: recipe is unlocked from start or via technology
- for entities/tiles/etc.: they are mentioned in a planet's autoplace list and the planet is unlocked

For ...

I see, thanks for the explanation. A flat decrease of 900000-something should work for my case then. Not sure if this is documented anywhere, might be helpful.

1. What did you do?
- Give a capturable unit-spawner 100% electrical resistance
i.e.
local bugspawner = data.raw["unit-spawner"]["biter-spawner"]
bugspawner.resistances = { { type = "electric", percent = 100 } }

2. What happened?
- turrets shooting capture bots at the spawner will now ...

Bots cannot upgrade entities with different collision boxes, if you found a way for them to do that provide exact steps please, see https://forums.factorio.com/3638.

Updated my post.
The issue is not different collision boxes, but different collision masks tile_buildability_rules. i.e. like ...

Same issue as https://forums.factorio.com/viewtopic.php?p=439933
It looks like the fix back then was just to disallow these upgrades in the planner, not actually preventing the bots to build the upgrade.
Selecting upgrades with different collision requirements is currently possible, so this might ...

Sorry for the short format, but this one seems pretty straightforward.
Seems to be either an oversight or intended but undocumented (and at least to me, very unexpected).
Happy to provide more data if this turns out more complicated.

Setup:
- Entity (type furnace in my case) with production_health ...

+1

assembling-machine has property enable_logistic_control_behavior, which would be great if furnaces could have that, too.

My use case is a furnace that constantly needs to lose health, which can currently be stopped by connecting it to the logistics network with a false condition. As doing this ...

That case is unfortunately working as intended. If it didn’t work that way, changing recipes on assembling machines would cause inserters to deadlock if they were mid swing when it changed.

If you’re going to use circuits with assemblers that accept fuel then you need to not feed them mixed fuel ...

1. What did you do?
- Create an entity with a dying_trigger_effect of create-entity and play-sound
- Copy of nuclear bomb effects but slightly modified

2. What happened?
- Game crashed when effect is triggered, according to log in playSoundWithDistanceLimits

3. What did you expect to happen ...

Oh, that works perfectly for my case, thanks!
Didn't realize opened is writable, but makes sense.

Hey Forum People,
Working on a Planet mod with a global electric network, but it seems there is no way to show the network stats?
LuaFlowStatistics API page mentions GUI a lot, but I can't find a way that actually shows them.
