Sure, but windows only and seems mostly vibe-coded with antigravity.

Get a platform independent version?

Agreed. However, for a custom status (e.g. low power/no power), I would need to know that this condition exists right now and there is not a good way to find out.

Thanks for the explanation.

(replying to my own post)

I tested this by replacing the ElectircEnergyInterface with a Lamp and that behaves as expected. But with a lamp, I can not control the energy consumption (only on/off).

So this look like a bug with ElectricEnergyInterface to me.

I have an entity like this:


--- @type data.ElectricEnergyInterfacePrototype
local power_entity = {
-- PrototypeBase
type = 'electric-energy-interface',
name = 'my-thing',
hidden = true,
hidden_in_factoriopedia = true,

-- ElectricEnergyInterfacePrototype
---@type data.ElectricEnergySource ...

Right now, I am using code similar to this:


local surface_index = 1
local known_networks = {}
for _, e in pairs (game.surfaces[surface_index].find_entities_filtered { type = 'electric-pole' }) do
known_networks[e.electric_network_id] = true
end

for id in pairs(known_networks) do
print(id)
end ...

Pretty straightforward ask:

- add a new EntityPrototypeFlag: "allow-gui". Adding this flag to an entity prototype makes Entities fire the "on_gui_opened" event when clicked.
- in any on_gui_opened event that is fired by an entity that has no "natural" GUI, the gui_type in the event is set to ...

Thanks for the quick answer. I will try a custom event first.

I have a mod that revolves around a SimpleEntityWithOwner at the core. Now I want to add a gui to it. The GUI is fully custom and works fine if I attach it e.g. to a container.

However, if I register to receive the on_gui_opened event for my custom entities, nothing happens. I never receive an ...

There are some complexities/issues with such a function since internally when a given require() is processed the game goes over several possible resolution options - and the first one to exist on disk is the one that gets used. That isn't such a big issue in itself - except that the logic is ...

With 2.1 coming at some point, I’d like to ask again to consider adding support for a stable “package loaded” key to the factorio runtime. It would make life for a lot of use cases (especially circular dependency resolution) so much easier.

It seems to me that something like this should exist in ...

With this tutorial being a bit dated, anyone who is willing to update it to a more current blender version?

At this point, I have a 3D entity in blender but literally no clue on how to create a sprite sheet from it. Most tutorials expect familiarity with blender (I have not).

Sounds harsh, but that is the type of change where AI excels. Claude wrote a mod that supports this in literally three minutes.

Get it from https://mods.factorio.com/mod/extended-underground-pipes. I tested it (it works) but I did not even look at the code. :-)

(If you don't like AI, don't ...

I have a mod with entities under script control (let's call them "io pins"). those entities are created when a parent is created and deleted when that parent is deleted. These entities support connecting wires (copper, red, green).

I can blueprint my mod entities and build them. If these io pins ...

There is no network 0. The network id is “binary coded” and a set bit means that a station is part of that network. If you want to have distinct networks, you need to use single bits, so 1, 2, 4, 8, 16, and so on.

0 is “no bit set” and a station with that value is not part of any network (no bit ...

With the miniloader redux mod, I have entities that look like this:

This is a freshly minted loader just sitting there. If you open the GUI, it opens the circuit network sub-GUI and shows red and green connections. That is because internally, the miniloader ...

Thanks. Appreciate you pointing those out. This is such a big API, I always learn new things.

I have a localised string that looks like this: open_gui_shift=Open GUI\n[font=default-semibold][color=128,206,240]Shift:[/color][/font] Open location on map

When I use this text as a tooltip, it renders like this:

Hi,

I have a gui with a number of elements (for train stations and trains). I want to be able to hover over a gui element (usually a piece of text like "xyz station" or "abc train") and that should show a minimap of either the train or station position.

There seems to be no rich text element for ...

Oh, that was non-obvious to me. Thanks for the explanation!
