# Running the server and client

### Prerequisites
* [Java 25](https://www.oracle.com/java/technologies/javase/jdk25-archive-downloads.html)

### Recommended
* [MongoDB 4.0+](https://www.mongodb.com/try/download/community)

### 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 `bin`, `language` folders from a repository with datamined game data and place them into your resources folder.
4. Run the server with `java -jar Nebula.jar` from your system terminal. This server 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 at least once to download game data.**
2. Install and have [Fiddler Classic](https://www.telerik.com/fiddler) running.
3. Copy and paste the following code into the Fiddlerscript tab of Fiddler Classic. Remember to save the fiddler script after you copy and paste it:

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

class Handlers
{
    static function OnBeforeRequest(oS: Session) {
        if (oS.host.EndsWith(".yostarplat.com") || oS.host.EndsWith(".stellasora.global")) {
            oS.oRequest.headers.UriScheme = "http";
            oS.host = "localhost"; // This can also be replaced with another IP address.
        }
    }
};
```

4. 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.
5. Login with your account name, the password field is ignored by the server and can be set to anything.

### Server commands
Server commands need to be run in the server console.

```
/account {create | delete} [username] (reserved player uid) = Creates or deletes an account.
/give [item id] x[amount] = Gives the targetted player an item.
/mail = Sends the targeted player a system mail.
/reload = Reloads the server config.
```
