The game supports mods as of v1.4.0 across all available platforms including Windows, Linux, Mac OSX, Android and iOS.

To use mods you’ll need to enable Mods in your Settings in-game

On Desktop versions of the game, it loads mods from your ~/documents/CitizenOfRomeDynastyAscendant/mods directory, creating the same if it does not exist upon first enabling mods

On iOS, it’s the app’s Documents/CitizenOfRomeDynastyAscendant/mods directory to which you can upload via iTunes or via the Files app

On Android, if external storage/sdcard is available, it uses the /CitizenOfRomeDynastyAscendant/mods directory there, else it uses the same path in the app’s private files directory

The game displays the exact path for mods in the Settings screen after you enable mods once

To use a mod, simply place its whole folder intact inside /CitizenOfRomeDynastyAscendant/mods/ and restart the game and move a month forward

To disable a mod rename it’s folder to include .disabled or simply delete it

Mod file structure

The game uses JavaScript (VueJS + VueX + custom stuff) that is run in a browser-like environment internally, and so mods are written with JavaScript and in the format detailed below

~/documents/CitizenOfRomeDynastyAscendant/mods/
  modName/
    assets/
      style.css
      eventImage1.svg
      ...
    events/
      event1Name.js
      ...
    monthly.js
    yearly.js

Note that while this is a recommended structure, the game’s modding API is permissive and works with other structures as well. The only keyword file names are that of monthly.js and yearly.js. Both files are themselves optional, as is style.css and any other assets

monthly.js and yearly.js should contain a single JavaScript array each containing a list of events to be executed every month and every year respectively, and the events should be listed with their full path and without the .js extension like so:

['/modName/events/event1Name', '/modName/events/event2Name']

style.css and any other .css files found will be included directly into the game’s UI

In each events js file you should use the following structure

{

  checkType, // String - one of 'general' (passes no args & runs `checkAndAct` once per month/year based on if the event is in monthly/yearly.js) | 'householdCharacters' | 'currentAndFormerHouseholdCharacters' | 'allCharacters' | 'nonHouseholdCharacters' (all 4 run `checkAndAct` once per each applicable character and pass `characterId` as the first argument, and `chunkFactor`),

  checkAndAct(characterId, { chunkFactor }) { // The arguments may or may not be passed based on `checkType` - see above. If `chunkFactor` is passed, you'll want to multiply your probabilities by it as the particular character may only be checked once every `chunkFactor` months/years for performance reasons
    if (/* Conditions for the event to run */) {
       /* Set up and run the event */
    }
  },

  methods: {
    method1(args) { .... },
    method2(args) { .... },
    .....
  }
}

getCharacter({ characterId })
  Returns an object containing character data

getJobsForCharacter({ characterId })

generateCharacter({ 
  characterFeatures: {
    isMale: Boolean,

    agnomen,
    birthMonth: Number (0-12),
    birthYear,
    spouseId,

invokeMethod({ event, method, context })
  Executes a `method` listed in the `methods` object of the selected `event`.
  `event` is the full path to your event like '/modName/events/event1Name'
  `context` is passed down as the sole argument for your method, usually you would like to pass down things like the characterId and any other relevant context like so `context: {characterId: characterId}`

pushInteractionModalQueue | pushInteractionModalButtonQueue | displayInteractionModal ({
  title,
  message,
  image: Base64 Image String,
  onHidden: { event, method, context },
  inputs: [
