Throughout the entire build and setup process a level of familiarity with the command line and preferably a Unix-like development environment is greatly advantageous.
### Hosting a server
We do not recommend hosting public servers. DLU is intended for small scale deployment, for example within a group of friends. It has not been tested for large scale deployment which comes with additional security risks.
We do not recommend hosting public servers. Darkflame Universe is intended for small scale deployment, for example within a group of friends. It has not been tested for large scale deployment which comes with additional security risks.
### Supply of resource files
Darkflame Universe is a server emulator and does not distribute any LEGO® Universe files. A separate game client is required to setup this server emulator and play the game, which we cannot supply. Users are strongly suggested to refer to the safe checksums listed in the resources tab below when checking if a client will work.
Darkflame Universe is a server emulator and does not distribute any LEGO® Universe files. A separate game client is required to setup this server emulator and play the game, which we cannot supply. Users are strongly suggested to refer to the safe checksums listed [here](#verifying-your-client-files) to see if a client will work.
## Build
Development of the latest iteration of Darkflame Universe has been done primarily in a Unix-like environment and is where it has been tested and designed for deployment. It is therefore highly recommended that Darkflame Universe be built and deployed using a Unix-like environment for the most streamlined experience.
## Steps to setup server
* [Clone this repository](#clone-the-repository)
* [Install dependencies](#install-dependencies)
* [Database setup](#database-setup)
* [Build the server](#build-the-server)
* [Configuring your server](#configuring-your-server)
* [Required Configuration](#required-configuration)
* [Optional Configuration](#optional-configuration)
* [Verify your setup](#verify-your-setup)
* [Running the server](#running-the-server)
* [User Guide](#user-guide)
### Prerequisites
#### Clone the repository
## Clone the repository
If you are on Windows, you will need to download and install git from [here](https://git-scm.com/download/win)
Then run the following command
```bash
git clone --recursive https://github.com/DarkflameUniverse/DarkflameServer
```
#### Python
Some tools utilized to streamline the setup process require Python 3, make sure you have it installed.
## Install dependencies
### Windows packages
Ensure that you have either the [MSVC C++ compiler](https://visualstudio.microsoft.com/vs/features/cplusplus/) (recommended) or the [Clang compiler](https://github.com/llvm/llvm-project/releases/) installed.
You'll also need to download and install [CMake](https://cmake.org/download/) (version <font size="4">**CMake version 3.18**</font> or later!).
### Choosing the right version for your client
DLU clients identify themselves using a higher version number than the regular live clients out there.
This was done make sure that older and incomplete clients wouldn't produce false positive bug reports for us, and because we made bug fixes and new content for the client.
### MacOS packages
Ensure you have [brew](https://brew.sh) installed.
You will need to install the following packages
```bash
brew install cmake gcc mariadb openssl zlib
```
If you're using a DLU client you'll have to go into the "CMakeVariables.txt" file and change the NET_VERSION variable to 171023 to match the modified client's version number.
### Linux packages
Make sure packages like `gcc`, and `zlib` are installed. Depending on the distribution, these packages might already be installed. Note that on systems like Ubuntu, you will need the `zlib1g-dev` package so that the header files are available. `libssl-dev` will also be required as well as `openssl`. You will also need a MySQL database solution to use. We recommend using `mariadb-server`.
### Enabling testing
While it is highly recommended to enable testing, if you would like to save compilation time, you'll want to comment out the enable_testing variable in CMakeVariables.txt.
It is recommended that after building and if testing is enabled, to run `ctest` and make sure all the tests pass.
For Ubuntu, you would run the following commands. On other systems, the package install command will differ.
### Using Docker
Refer to [Docker.md](/Docker.md).
```bash
sudo apt update && sudo apt upgrade
For Windows, refer to [Docker_Windows.md](/Docker_Windows.md).
# Install packages
sudo apt install build-essential gcc zlib1g-dev libssl-dev openssl mariadb-server cmake
```
### Linux builds
Make sure packages like `gcc`, `cmake`, and `zlib` are installed. Depending on the distribution, these packages might already be installed. Note that on systems like Ubuntu, you will need the `zlib1g-dev` package so that the header files are available. `libssl-dev` will also be required as well as `openssl`.
#### Required CMake version
This project uses <font size="4">**CMake version 3.18**</font> or higher and as such you will need to ensure you have this version installed.
You can check your CMake version by using the following command in a terminal.
```bash
cmake --version
```
CMake must be version 3.14 or higher!
If you are going to be using an Ubuntu environment to run the server, you may need to get a more recent version of `cmake` than the packages available may provide.
#### Build the repository
The general approach to do so would be to obtain a copy of the signing key and then add the CMake repository to your apt.
You can do so with the following commands.
[Source of the below commands](https://askubuntu.com/questions/355565/how-do-i-install-the-latest-version-of-cmake-from-the-command-line)
```bash
# Remove the old version of CMake
sudo apt purge --auto-remove cmake
# Prepare for installation
sudo apt update && sudo apt install -y software-properties-common lsb-release && sudo apt clean all
# Obtain a copy of the signing key
wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | gpg --dearmor - | sudo tee /etc/apt/trusted.gpg.d/kitware.gpg >/dev/null
# Add the repository to your sources list.
sudo apt-add-repository "deb https://apt.kitware.com/ubuntu/ $(lsb_release -cs) main"
# Next you'll want to ensure that Kitware's keyring stays up to date
sudo apt update
sudo apt install kitware-archive-keyring
sudo rm /etc/apt/trusted.gpg.d/kitware.gpg
# If sudo apt update above returned an error, copy the public key at the end of the error message and run the following command
# if the error message was "The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6AF7F09730B3F0A4"
# then the below command would be "sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6AF7F09730B3F0A4"
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <TheCopiedPublicKey>
# Finally update and install
sudo apt update
sudo apt install cmake
```
## Database setup
First you'll need to start MariaDB.
For Windows the service is always running by default.
For MacOS, run the following command
```bash
brew services start mariadb
```
For Linux, run the following command
```bash
sudo systemctl start mysql
# If systemctl is not a known command on your distribution, try the following instead
sudo service mysql start
```
<font size="4">**You will need to run this command every time you restart your environment**</font>
If you are using Linux and `systemctl` and want the MariaDB instance to start on startup, run the following command
```bash
sudo systemctl enable --now mysql
```
Once MariaDB is started, you'll need to create a user and an empty database for Darkflame Universe to use.
First, login to the MariaDB instance.
To do this on Ubuntu/Linux, MacOS, or another Unix like operating system, run the following command in a terminal
```bash
# Logs you into the MariaDB instance as root
sudo mysql
```
For Windows, run the following command in the `Command Prompt (MariaDB xx.xx)` terminal
```bash
# Logs you into the mysql instance
mysql -u root -p
# You will then be prompted for the password you set for root during installation of MariaDB
```
Now that you are logged in, run the following commands.
```bash
# Creates a user for this computer which uses a password and grant said user all privileges.
# Change mydarkflameuser to a custom username and password to a custom password.
GRANT ALL ON *.* TO 'mydarkflameuser'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
# Then create a database for Darkflame Universe to use.
CREATE DATABASE darkflame;
```
## Build the server
You can either run `build.sh` when in the root folder of the repository:
```bash
./build.sh
```
Or manually run the commands used in `build.sh`:
Or manually run the commands used in [build.sh](build.sh).
```bash
# Create the build directory, preserving it if it already exists
mkdir -p build
cd build
### Notes
Depending on your operating system, you may need to adjust some pre-processor defines in [CMakeVariables.txt](./CMakeVariables.txt) before building:
* If you are on MacOS, ensure OPENSSL_ROOT_DIR is pointing to the openssl root directory.
* If you are using a Darkflame Universe client, ensure NET_VERSION is changed to 171023.
# Run CMake to generate make files
cmake ..
## Configuring your server
This server has a few steps that need to be taken to configure the server for your use case.
# To build utilizing multiple cores, append `-j` and the amount of cores to utilize, for example `cmake --build . --config Release -j8'
cmake --build . --config Release
```
### Required Configuration
Darkflame Universe can run with either a packed or an unpacked client.
Navigate to `build/sharedconfig.ini` and fill in the following fields:
* `mysql_host` (This is the IP address or hostname of your MariaDB server. This is highly likely `localhost`)
* If you setup your MariaDB instance on a port other than 3306, which can be done on a Windows install, you will need to make this value `tcp://localhost:portNum` where portNum is replaced with the port you chose to run MariaDB on.
* `mysql_database` (This is the database you created for the server)
* `mysql_username` (This is the user you created for the server)
* `mysql_password` (This is the password for the user you created for the server)
* `client_location` (This is the location of the client files. This should be the folder path of a packed or unpacked client)
* Ideally the path to the client should not contain any spaces.
### MacOS builds
Ensure `cmake`, `zlib` and `open ssl` are installed as well as a compiler (e.g `clang` or `gcc`).
In the repository root folder run the following. Ensure -DOPENSSL_ROOT_DIR=/path/to/openssl points to your openssl install location
```bash
# Create the build directory, preserving it if it already exists
mkdir -p build
cd build
# Run CMake to generate build files
cmake .. -DOPENSSL_ROOT_DIR=/path/to/openssl
# Get cmake to build the project. If make files are being used then using make and appending `-j` and the amount of cores to utilize may be preferable, for example `make -j8`
cmake --build . --config Release
```
### Windows builds (native)
Ensure that you have either the [MSVC](https://visualstudio.microsoft.com/vs/) or the [Clang](https://github.com/llvm/llvm-project/releases/) (recommended) compiler installed. You will also need to install [CMake](https://cmake.org/download/). Currently on native Windows the server will only work in Release mode.
#### Build the repository
```batch
:: Create the build directory
mkdir build
cd build
:: Run CMake to generate make files
cmake ..
:: Run CMake with build flag to build
cmake --build . --config Release
```
#### Windows for ARM has not been tested but should build by doing the following
```batch
:: Create the build directory
mkdir build
cd build
:: Run CMake to generate make files
cmake .. -DMARIADB_BUILD_SOURCE=ON
:: Run CMake with build flag to build
cmake --build . --config Release
```
### Windows builds (WSL)
This section will go through how to install [WSL](https://docs.microsoft.com/en-us/windows/wsl/install) and building in a Linux environment under Windows. WSL requires Windows 10 version 2004 and higher (Build 19041 and higher) or Windows 11.
#### Open the Command Prompt application with Administrator permissions and run the following:
```bash
# Installing Windows Subsystem for Linux
wsl --install
```
#### Open the Ubuntu application and run the following:
```bash
# Make sure the install is up to date
apt update && apt upgrade
# Make sure the gcc, cmake, and build-essentials are installed
sudo apt install gcc
sudo apt install cmake
sudo apt install build-essential
```
[**Follow the Linux instructions**](#linux-builds)
### ARM builds
AArch64 builds should work on linux and MacOS using their respective build steps. Windows ARM should build but it has not been tested
### Updating your build
To update your server to the latest version navigate to your cloned directory
```bash
cd /path/to/DarkflameServer
```
run the following commands to update to the latest changes
```bash
git pull
git submodule update --init --recursive
```
now follow the build section for your system
## Setting up the environment
### Resources
#### LEGO® Universe 1.10.64
This repository does not distribute any LEGO® Universe files. A full install of LEGO® Universe version 1.10.64 (latest) is required to finish setting up Darkflame Universe.
Known good SHA256 checksums of the client:
- `8f6c7e84eca3bab93232132a88c4ae6f8367227d7eafeaa0ef9c40e86c14edf5` (packed client, rar compressed)

Known good *SHA1* checksum of the DLU client:
- `91498e09b83ce69f46baf9e521d48f23fe502985` (packed client, zip compressed)
How to generate a SHA256 checksum:
```bash
# Replace <file> with the file path to the client
# If on Linux or MacOS
shasum -a 256 <file>
# If on Windows
certutil -hashfile <file> SHA256
```
#### Unpacking the client
* Clone lcdr's utilities repository [here](https://github.com/lcdr/utils)
* Use `pkextractor.pyw` to unpack the client files if they are not already unpacked
#### Setup resource directory
* In the `build` directory create a `res` directory if it does not already exist.
* Copy over or create symlinks from `macros`, `BrickModels`, `chatplus_en_us.txt`, `names`, and `maps` in your client `res` directory to the server `build/res` directory
* Unzip the navmeshes [here](./resources/navmeshes.zip) and place them in `build/res/maps/navmeshes`
#### Setup locale
* In the `build` directory create a `locale` directory if it does not already exist
* Copy over or create symlinks from `locale.xml` in your client `locale` directory to the `build/locale` directory
#### Client database
* Move the file `res/cdclient.fdb` from the unpacked client to the `build/res` folder on the server.
* The server will automatically copy and convert the file from fdb to sqlite should `CDServer.sqlite` not already exist.
* You can also convert the database manually using `fdb_to_sqlite.py` using lcdr's utilities. Just make sure to rename the file to `CDServer.sqlite` instead of `cdclient.sqlite`.
* Migrations to the database are automatically run on server start. When migrations are needed to be ran, the server may take a bit longer to start.
### Database
Darkflame Universe utilizes a MySQL/MariaDB database for account and character information.
Initial setup can vary drastically based on which operating system or distribution you are running; there are instructions out there for most setups, follow those and come back here when you have a database up and running.
* All that you need to do is create a database to connect to. As long as the server can connect to the database, the schema will always be kept up to date when you start the server.
#### Configuration
After the server has been built there should be four `ini` files in the build director: `sharedconfig.ini`, `authconfig.ini`, `chatconfig.ini`, `masterconfig.ini`, and `worldconfig.ini`. Go through them and fill in the database credentials and configure other settings if necessary.
#### Migrations
The database is automatically setup and migrated to what it should look like for the latest commit whenever you start the server.
#### Verify
### Optional Configuration
* After the server has been built there should be five `ini` files in the build directory: `sharedconfig.ini`, `authconfig.ini`, `chatconfig.ini`, `masterconfig.ini`, and `worldconfig.ini`.
* `authconfig.ini` contains an option to enable or disable play keys on your server. Do not change the default port for auth.
* `chatconfig.ini` contains a port option.
* `masterconfig.ini` contains options related to permissions you want to run your servers with.
* `sharedconfig.ini` contains several options that are shared across all servers
* `worldconfig.ini` contains several options to turn on QOL improvements should you want them. If you would like the most vanilla experience possible, you will need to turn some of these settings off.

## Running the server
If everything has been configured correctly you should now be able to run the `MasterServer` binary. Darkflame Universe utilizes port numbers under 1024, so under Linux you either have to give the binary network permissions or run it under sudo.
If everything has been configured correctly you should now be able to run the `MasterServer` binary which is located in the `build` directory. Darkflame Universe utilizes port numbers under 1024, so under Linux you either have to give the `AuthServer` binary network permissions or run it under sudo.
To give `AuthServer` network permissions and not require sudo, run the following command
```bash
sudo setcap 'cap_net_bind_service=+ep' AuthServer
```
and then go to `build/masterconfig.ini` and change `use_sudo_auth` to 0.

### Admin levels
The admin level, or Game Master level (hereafter referred to as gmlevel), is specified in the `accounts.gm_level` column in the MySQL database. Normal players should have this set to `0`, which comes with no special privileges. The system administrator will have this set to `9`, which comes will all privileges. gmlevel `8` should be used to give a player a majority of privileges without the safety critical once.

* Open it in a text editor and locate where it says `AUTHSERVERIP=0:`
@ -273,155 +244,89 @@ To connect to a server follow these steps:
* Launch `legouniverse.exe`, through `wine` if on a Unix-like operating system
* Note that if you are on WSL2, you will need to configure the public IP in the server and client to be the IP of the WSL2 instance and not localhost, which can be found by running `ifconfig` in the terminal. Windows defaults to WSL1, so this will not apply to most users.
### Brick-By-Brick building
## Brick-By-Brick building
Should you choose to do any brick building, you will want to have some form of a http server that returns a 404 error since we are unable to emulate live User Generated Content at the moment. If you attempt to do any brick building without a 404 server running properly, you will be unable to load into your game. Python is the easiest way to do this, but any thing that returns a 404 should work fine.
* Note: the client hard codes this request on port 80.
Brick-By-Brick building requires `PATCHSERVERIP=0:` in the `boot.cfg` to point to a HTTP server which always returns `HTTP 404 - Not Found` for all requests. This can be achieved by pointing it to `localhost` while having `sudo python -m http.server 80` running in the background.
<font size="4">**If you do not plan on doing any Brick Building, then you can skip this step.**</font>
### In-game commands
Here is a summary of the commands available in-game. All commands are prefixed by `/` and typed in the in-game chat window. Some commands requires admin privileges. Operands within `<>` are required, operands within `()` are not. For the full list of in-game commands, please checkout [the source file](./dGame/dUtilities/SlashCommandHandler.cpp).

### Allowing a user to build in Brick-by-Brick mode
Brick-By-Brick building requires `PATCHSERVERIP=0:` and `UGCSERVERIP=0:` in the `boot.cfg` to point to a HTTP server which always returns `HTTP 404 - Not Found` for all requests. This can be most easily achieved by pointing both of those variables to `localhost` while having running in the background.
Each client must have their own 404 server running if they are using a locally hosted 404 server.
```bash
# If on linux run this command. Because this is run on a port below 1024, binary network permissions are needed.
sudo python3 -m http.server 80
# If on windows one of the following will work when run through Powershell or Command Prompt assuming python is installed
python3 -m http.server 80
python http.server 80
py -m http.server 80
```
## Updating your server
To update your server to the latest version navigate to your cloned directory
```bash
cd path/to/DarkflameServer
```
Run the following commands to update to the latest changes
```bash
git pull
git submodule update --init --recursive
```
Now follow the [build](#build-the-server) section for your system and your server is up to date.
## In-game commands
* A list of all in-game commands can be found [here](./docs/Commands.md).
## Verifying your client files
### LEGO® Universe 1.10.64
To verify that you are indeed using a LEGO® Universe 1.10.64 client, make sure you have the full client compressed **in a rar file** and run the following command.
```bash
# Replace <file> with the file path to the zipped client
# If on Linux or MacOS
shasum -a 256 <file>
# If on Windows using the Command Prompt
certutil -hashfile <file> SHA256
```
Below are known good SHA256 checksums of the client:

If the returned hash matches one of the lines above then you can continue with setting up the server. If you are using a fully downloaded and complete client from live, then it will work, but the hash above may not match. Otherwise you must obtain a full install of LEGO® Universe 1.10.64.
### Darkflame Universe Client
Darkflame Universe clients identify themselves using a higher version number than the regular live clients out there.
This was done make sure that older and incomplete clients wouldn't produce false positive bug reports for us, and because we made bug fixes and new content for the client.
To verify that you are indeed using a Darkflame Universe client, make sure you have the full client compressed **in a zip file** and run the following command.
```bash
# Replace <file> with the file path to the zipped client
# If on Linux or MacOS
shasum -a 1 <file>
# If on Windows using the Command Prompt
certutil -hashfile <file> SHA1
```
Known good *SHA1* checksum of the Darkflame Universe client:
- `91498e09b83ce69f46baf9e521d48f23fe502985` (packed client, zip compressed)
