on_configuration_changed on mod update

[AntiElitz]

I would like to run code when my mod gets updated, but on_configuration_changed only fires on factorio update or mod add/removal. May you also make it fire on mod update?

Are you sure?

[quote=api]This is called any time the game version changes and any time mod versions change including adding or removing mods.[/quote]

Lots of mods use the event to update internal state (eg. stuff on `global`) when they have been updated. It definitely works. Something like this:

Code: Select all

script.on_configuration_changed( function(event)
  local changed = event.mod_changes and event.mod_changes["your-mod-name"]

  if changed then -- something to do with your mod

    if not changed.old_version then
      -- your mod was added
    elseif not changed.new_version then
      -- your mod was removed
    else
      -- your mod was updated
    end

  end
end )

strange it doesn't trigger for me, but when i update factorio. Probably I did a misstake in my code than. Thx guys

Did you get any errors when your script ran? Also, how were you testing that it was working? In that particular event it's usually best to use the global `log()` function to output stuff to game log (as game.players[id].print won't be available) in some cases.
