Rocket Count Exporter - Factorio Mod

control.lua

require "defines"

-- UNTESTED IN MULTIPLAYER
-- UNTESTED WITH ACTUAL ROCKET LAUNCHING
-- MINIMALLY TESTED WITH SAVE LOADING

-- In order to use this mod:
-- 1. Download all the files from this gist
-- 2. Create a new folder in your mods folder, called "RocketCountExporter_1.0.0"
-- 3. Place all the downloaded files in this folder
-- 4. Change the configuration to your likings

-- This should not break any saves, since it's just loading information and exporting to a file.
-- This means that you can just remove the mod if needed without any consequences other than the file not being updated anymore.

function update_count(players)
    -- Define the file name here (the file will be made in %APPDATA%\Roaming\Factorio\script-output)
    -- You can hook this up on your OBS or any other application that listens for file modifications
    file_name = "rocket_count.txt"
    -- The string format to use, where %d is the actual rocket count, if you just want the count, use "%d" only
    string_format = "Rockets: %d / 9001"

    -- Don't change anything below!!
    rocket_count = 0
    for index, player in pairs(players) do
        if player.gui.left.rocket_score.rocket_count ~= nil then
            -- Hopefully this works, it might break if the game gets updated later, because this is using the current value in the GUI
            rocket_count = player.gui.left.rocket_score.rocket_count.caption
        end
    end
    game.write_file(file_name, string.format(string_format, rocket_count))
end

    update_count(game.players)
end)
script.on_event(defines.events.on_rocket_launched, function(event)
