Running the server and client

Prerequisites

• Java 17 JDK

Recommended

• MongoDB 4.0+

Compiling the server

1. Open your system terminal, and compile the server with ./gradlew jar
2. Create a folder named resources in your server directory
3. Download the Config, TextMap, and ExcelBin folders from https://github.com/Dimbreath/StarRailData and place them into your resources folder.
4. Delete the /resources/Config/LevelOutput folder.
5. Download the Config folder from https://gitlab.com/Melledy/LunarCore-Configs and place them into your resources folder. These are for world spawns and are very important for the server.
6. Run the server with java -jar LunarCore.jar from your system terminal. Lunar Core comes with a built-in internal MongoDB server for its database, so no Mongodb installation is required. However, it is highly recommended to install Mongodb anyway.

Connecting with the client (Fiddler method)

1. Log in with the client to an official server and Hoyoverse account at least once to download game data.
2. Install and have Fiddler Classic running.
3. Set fiddler to decrypt https traffic. (Tools -> Options -> HTTPS -> Decrypt HTTPS traffic) Make sure ignore server certificate errors is checked as well.
4. Copy and paste the following code into the Fiddlerscript tab of Fiddler Classic:

import System;
import System.Windows.Forms;
import Fiddler;
import System.Text.RegularExpressions;

class Handlers
{
    static function OnBeforeRequest(oS: Session) {
        if (oS.host.EndsWith(".starrails.com") || oS.host.EndsWith(".hoyoverse.com") || oS.host.EndsWith(".mihoyo.com") || oS.host.EndsWith(".bhsr.com")) {
            oS.host = "localhost"; // This can also be replaced with another IP address.
        }
    }
};

5. If autoCreateAccount is set to true in the config, then you can skip this step. Otherwise, type /account create [account name] in the server console to create an account.
6. Login with your account name, the password field is ignored by the server and can be set to anything.
