+1, pointing to specific inventory slots would be nice. Even if separated from the Inventory type for implementation reasons. I can think of trying to link to specific slots in the player's inventory/guns/ammo that would also benefit from the 1-slot approach.

If possible, it would be nice to be able to describe elements as a list of ItemPrototypeName and possibly extra info. I would like to use this to reimplement certain UIs from pYanodons, particularly caravans and dig sites where food (fuel) can be inserted, and having a semi-custom or fully ...

This might be caused by the sprite being rendered in front of the background red in the custom variation, as opposed to behind it in the crafter UI. If so, it might be nice to have a property in EmptySpriteInfo that specifies an "overlay color" or whether to render the usual red overlay when empty ...

Inventory filters are fully supported. Things like crafting machines *do not use filters*, instead they use secondary logic to restrict what can go into a slot based on the active recipe. The custom gui logic does not have special case logic to account for displaying those restrictions.

I can’t say I agree with this proposal as it stands. Spoilage refers not only to the flavor of the decay process, but also to a concrete game mechanic in which items get immediately swapped out while in machines, etc.

Players intuitively understand what it means for a biter egg to "spoil". It ...

After following up on boskid's advice in 135371 , I noticed that base_valve_xy_offset_when_horizontal and base_valve_xy_offset_when_vertical do not function independently. Neither will function properly when the other is nil or set to {0, 0}. This isn't documented, so I assuming it's a bug, probably ...

It defaults to 2, however if you specify this value manually it will just trigger usual "prototypes changed" loading mode where various structures are rebuilt and this may fix the pump in the same way as loading save while holding Ctrl to force prototypes changed mode manually.

Hello everyone, fellow masochists. How is the mod's development coming along? It’s been a long time. I’d love to do some thinking, daydreaming, and writing about something new. But I don’t know what stage the development is at—what’s been done and what hasn’t. Is there anywhere I can check on the ...

Thanks for the report. This is Not a bug.

Realistically the tank_spacing becomes meaningful only when fluid wagon has at least 3 tanks and since you are showing fluid wagon with 2 tanks, you will not see any behavior changes. There are 2 sets of tank spacing: one is visual related to valves ...

Burner generators do this automatically

Title, the tank_spacing property on fluid wagons doesn't seem to do anything. I got a bug report that describes an issue with 2-port fluid wagons. Since the tank_spacing property is new, I tried that out to fix it. It seems to fix the issue, but as far as I can tell it doesn't do anything else.

Honestly, it feels like this would be solved by just making recommended dependencies only change where the mod is shown in the UI, then you can use whatever other dependency marker to define how it would load. If recommended dependencies were load order agnostic, I could add another optional ...

Normally, when using the API, fields/keys always follow the pattern of lowercase letters with underscores as separators between words. However, for the fuel-category search filter when filtering for item prototypes, the key is "fuel-category" instead of the expected "fuel_category". This is ...

Fair enough, thanks for the quick response.

As in title, I can't get quality fish (entity) by any means I know of. I've tried the following:


Placing legendary fish in water with the drop keybind (z)
Script creating fish with the following command: /c game.surfaces[1].create_entity{name = "fish", quality = "legendary, position = {0, 0 ...

Not even remotely possible unless you re-implement the entire mechanic via script. Which itself isnt very feasible.

Ah, that makes sense. It's unfortunate that there isn't a better solution right now.

My suggestion is to add a function to LuaCircuitNetwork that enables a monitor on it, causing a new event type to be fired every time the signals on the network change. And possibly with support for signal filters because many control behaviours only use one signal or one signal kind. (Set value ...
