Darkflame Universe
## Introduction
Darkflame Universe (DLU) is a server emulator for LEGO® Universe. Development started in 2013 and has gone through multiple iterations and is now able to present a near perfect emulation of the game server.
### LEGO® Universe
Developed by NetDevil and The LEGO Group, LEGO® Universe launched in October 2010 and ceased operation in January 2012.
## License
Darkflame Universe is licensed under AGPLv3, please read [LICENSE](LICENSE). Some important points:
* We are not liable for anything you do with the code
* The code comes without any warranty what so ever
* You must disclose any changes you make to the code when you distribute it
* Hosting a server for others counts as distribution
## Disclaimers
### Setup difficulty
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.
### 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.
## 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.
### Prerequisites
#### Clone the repository
```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.
### 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.
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.
### Using Docker
Refer to [Docker.md](/Docker.md).
For Windows, refer to [Docker_Windows.md](/Docker_Windows.md).
### 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`.
CMake must be version 3.14 or higher!
#### Build the repository
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`:
```bash
# Create the build directory, preserving it if it already exists
mkdir -p build
cd build
# Run CMake to generate make files
cmake ..
# 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
```
### 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.
