This needs to be done by defining gui styles at data stage https://lua-api.factorio.com/latest/pro ... Style.html

Simple entities already support graphics variations by defining pictures or animations . They also support rotated sprites in the form of picture . However there is no way to get both rotations and variations at the same time.
There is a data type for this already: RotatedAnimationVariations ...

What does it do? How does it relate to the graphics definition? What is the default? I'm making a mod with a complex graphics definition on a corpse prootype and need to know if its even relevant to what i'm doing ...

Thank you!

This is an interesting idea
I think it can be made performant if stuff only gets checked in the on_train_changed_state event. For example, amount of time spent waiting at a signal or station could probably be gathered from that, and then displayed to the user when needed.
And while that doesn't give ...

Have you also modified the collision mask of the assembler?
If not, it will require the area to collide with lava, while also colliding with lava itself, preventing its placement anywhere. Collision masks functions independently of the tile buildability rules.

You can't do that. It is not possible to interact with built in guis apart from adding an element relative to them. And the ___ network sub guis are considered as part of the parent gui, and you can't make an element relative to only one of them, but rather relative to both windows as a whole

player.opened is not available anymore during the on_player_configured_blueprint event.

Because by that point the GUI is closed. In the previous message i said save it in on_gui_opened event, and by that i meant write it to storage, and then read it from storage in the on_player_configured ...

It can be in the cursor_stack, but doesn't have to . It could be in the cursor, but also in inventory, or in another entity.
What i'm think of for the solution is in the on_gui_opened event, if the opened gui is of type blueprint, save the blueprint that you can get from player.opened, and if the ...

Running into this issue myself with my own icons, and also noting that it happens with base game barrel icons, especially visible at the top, where there is a cutout in the shadow near the thing sticking out of the lid and it looks like it "casts an inverse shadow"

1. The animation is infinite from the moment it is created (without player intervention).

Actually, any entity can have that, its called a stateless visualisation , an animation that plays regardless of the state of the entity or the game. Creating a continuos looping animation is easy.
Note ...

You are wrapping defines.events.xxx in parentheses, thus providing a table when the on_event function expects a defines.events number or a string of the same name. Remove the {} and it should work. (assuming radars even have gui, i don't remember if they do with energy sources other than burner)

FFF-436 shows factorio uses a custom mapping function to convert text to some standard representation. I'm asking for the same mapping to be exposed to mods in some way, for the same reasons it exists in the base game, mainly for searching. I imagine it should take a string (such as one returned in ...

I am already changing the style of the dropdown.

But you are not changing the opened_sound on the style. If you did, it would display in the Ctrl+F6 menu

local scope is only within that command (or less)
I don't remember whether global is permanent or lasts until you reload the save.
But all code snippets you provided do the same thing. In this case variables are optional.

This is still the case, both output_fluid_box and mode properties are wrong

The UtilitySounds prototype only holds some predefined sounds. For custom sounds, you beed to define a Sound Protoype https://lua-api.factorio.com/latest/pro ... otype.html

There is a way to get the status of an entity , however it returns a defines enum with around 70 values, and its the job of the mod to match it to the corresponding diode color . This is unnecessary work that must be done if the status needs to be displayed anywhere in the mod, especially so given ...

I don't think this would work as there is no way to change how the station reads items from the train without physically removing items ordisconnecting the wagons from the train. One could however make a separate entity for reading the contents of a specific wagon.
