Is there any way to detect if a technology got un-researched in the map editor? I couldn't find any event that gets triggered or something like that. I want to revert changes I did on_research_finished. It's a very minor issue but I wondered if it is possible at all.

If you do this with the console you could mayby use on_console_command
https://lua-api.factorio.com/latest/eve ... le_command
but I think that just works in a running game, but I am not sure

I mean the “Un-research” button in the technology screen. I hadn’t thought about console commands yet. Right now I am making sure everything is in the right state on_research_finished and on_technology_effects_reset.

I actually never realized an un-research button, but I never really used the map editor.
But I think a button belongs to a GUI, so maybe this on_gui_click could work https://lua-api.factorio.com/latest/eve ... _gui_click

That only fires for custom GUIs, not base game ones. I also don’t want to “use a sledgehammer to crack a nut”. I am mostly fine with how I solved it for now, since it only poses a problem if people mess around in the editor or use console commands. And it’ll get fixed as soon as they research the next technology in the “normal” way.

They added on_research_reversed viewtopic.php?f=3&t=95683

Yeah noticed that as well. Didn’t have time to test it yet, but the description in the docs sounds like it’s exactly what I was missing. The devs are just awesome!

@Moderators: I wouldn’t mind if this got moved to implement modding interface request.
