Boss, hello!
Please tell me how to add signals to your mod as a separate list so that they change the icon background?
With graphics, I understand that I need to make additional pictures, but I don’t know how to add the signals themselves to the code as a separate “data-update” file.
For example, in the mod https://mods.factorio.com/mod/nixie-tubes there is a “?” sign, and it is specified as “qmark”, and in yours it is specified as “question-mark”, and the background does not change accordingly.
Can you tell me how to create a file with a list correctly? The file will be convenient because you can separately enable some icons, and if the mod is updated, the changes will not be overwritten (and if you add them to the general “punctuation_signals” list, then everything will disappear after the update).
