Help with adding game to Extensions

[lornlynx]

Hey, I tried adding "Nier: Automata" to as a custom game to the extensions, as it isn't included in the games tab.

I followed this guide (wihtout the user environmnent and installation patterns): https://wiki.nexusmods.com/index.php/Creating_a_game_extension_for_Vortex

It appears in the list but vortex tells me it failed with the implementation.

 

Here's the file's I've added to appdata:

 

 

The info.json and the index.js code:

{
  "name": "Game: Nier: Automata",
  "author": "lornlynx",
  "version": "0.0.1",
  "description": "Nier: Automata"
}

// Nexus Mods domain for the game. e.g. nexusmods.com/nierautomata
const GAME_ID = 'nierautomata';

//Steam Application ID, you can get this from https://steamdb.info/apps/
const STEAMAPP_ID = '524220';

//GOG Application ID, you can get this from https://www.gogdb.org/
//const GOGAPP_ID = '1133514031';


//Import some assets from Vortex we'll need.
const path = require('path');
const { fs, log, util } = require('vortex-api');


//Add this to the top of the file
const winapi = require('winapi-bindings');

function findGame() {
  try {
    const instPath = winapi.RegGetValue(
      'HKEY_LOCAL_MACHINE',
      'SOFTWARE\\WOW6432Node\\Valve\\Steam\\Apps\\' + STEAM_ID,
      'PATH');
    if (!instPath) {
      throw new Error('empty registry key');
    }
    return Promise.resolve(instPath.value);
  } catch (err) {
    return util.GameStoreHelper.findByAppId([STEAMAPP_ID])
      .then(game => game.gamePath);
  }
}

function prepareForModding(discovery) {
    return fs.readdirAsync(path.join(discovery.path, 'NieRAutomata'.));
}

function main(context) {
    //This is the main function Vortex will run when detecting the game extension. 
    
    context.registerGame({
        id: GAME_ID,
        name: 'Nier: Automata',
        mergeMods: true,
        queryPath: findGame,
        supportedTools: [],
        queryModPath: () => 'NieRAutomata',
        logo: 'gameart.jpg',
        executable: () => 'NieRAutomata.exe',
        requiredFiles: [
          'NieRAutomata.exe'
        ],
        setup: undefined,
        environment: {
          SteamAPPId: STEAMAPP_ID,
        },
        details: {
          steamAppId: STEAMAPP_ID,
        },
    });

    return true
}

module.exports = {
    default: main,
  };

any help appreciated

I don't have a copy of Nier to test with, but the reason it won't load is because you have a syntax error on line 36 of your index.js file: there's an extra '.' that shouldn't be there.

 

The only other thing that jumps out at me is that you're not actually using your prepareForModding function. You need to change line 54 from setup: undefined to setup: prepareForModding to actually use it.

 

At least on my machine I can change those two things and the extension successfully loads (I don't have the game though, so that's the best I can tell you).
