## Prerequisites

- [MongoDB](https://www.mongodb.com/try/download/community)

## Installation

### From Source

#### Requirements

- [Rust](https://www.rust-lang.org/tools/install)
- [MongoDB](https://www.mongodb.com/try/download/community-edition)
- [Protobuf Compiler (protoc)](https://github.com/protocolbuffers/protobuf/releases/download/v26.1/protoc-26.1-win64.zip). You should manually extract it to somewhere and add `bin` subfolder to the system environment variable `PATH`.

#### Building

#### Using xtasks (recommended)

```sh
git clone https://git.xeondev.com/reversedrooms/FireflySR.git
cd FireflySR
cargo xtask run
```

##### To run it with automatic recompilation when any Rust files are changed

```sh
cargo xtask watch
```

### From Pre-built Binaries

Navigate to the [Releases](https://git.xeondev.com/reversedrooms/FireflySR/releases)
page and download the latest release for your platform.

## Usage

To begin using the server, you need to run three servers: `sdkserver`, `dispatch` and `gameserver`

If you installed from pre-built binaries, navigate to the directory where you downloaded
the binaries and either a) double-click on the following executable names or b)
run the following in a terminal:

```sh
./gameserver
./dispatch
./sdkserver
```

##### Note: the `assets` folder should be in the same directory with the `gameserver`, otherwise it will not boot up.

## Configuration
By default, servers will try to use local mongodb (at 127.0.0.1:27017),
this should work out of box if you installed MongoDB on your machine.
<br>
You can change this in configuration file of specific server.
Currently only sdkserver and gameserver communicate with database, so if you **need** to configure it,
edit sdkserver.json and gameserver.json files.

## Connecting

### For the latest 2.3 Beta patch

If you want to play the latest Beta patch, the `mhypbase.dll` patch for 2.2.51 OS is not usable. You should use a separate proxy like [FireflySR.Tool.Proxy](https://git.xeondev.com/YYHEggEgg/FireflySR.Tool.Proxy) (Prebuilt binary can be downloaded [here](https://git.xeondev.com/YYHEggEgg/FireflySR.Tool.Proxy/releases)).

Also, you need to configure `disable_password_check` in `sdkserver.json`. That is to say, if you have used a older version, you should go to the configuration file **in the root directory** and check if it's `true`.

Clients (2.3 Beta v3):

- [CN - 2.2.53](https://autopatchcn.bhsr.com/client/beta/20240517110535_d7lJoh4jYXkVGXI1/StarRail_2.2.53.zip)
- [OS - .2.53](https://autopatchos.starrails.com/client/Beta/20240517111205_PZfNSHVLH509e76v/StarRail_.2.53.zip)

Notice: **CN Package may not have languages other than Chinese, and vice versa**. Be careful when choosing which to download; luckily they are all compatiable with this server.

### For v1 Players

[Get 2.3 beta client v1(.51)](https://autopatchos.starrails.com/client/Beta/20240501125700_dUBAjS7YiX9nF7mJ/StarRail_2.2.51.zip),
replace [mhypbase.dll](https://git.xeondev.com/reversedrooms/FireflySR/raw/branch/master/mhypbase.dll)
file in your game folder, it will redirect game traffic (and disable in-game censorship)
