Nexium Engine

3D cross-platform game engine

Nexium Engine is a feature-packed, cross-platform game engine to create 3D games from a unified interface. It provides a comprehensive set of common tools so that users can focus on making games without having to reinvent the wheel. Now, it is currently under active development. In the future games can be exported with one click to a number of platforms, including the major desktop platforms (Linux, macOS, Windows), mobile platforms (Android, iOS)

Free, open source

Nexium is completely free and open source under the very permissive MIT license. No strings attached, no royalties, nothing. The users' games are theirs, down to the last line of engine code. Nexium's development is fully independent, and it is not intended for profit.

99.9% of Nexium Engine was developed by Valerii Koniushenko. Also, it has previous versions, mainly: VaKon2D, VaKon3D, Segalay – you can find it on the author's repositories Valerii Koniushenko.

Getting the engine

Windows

Pre-requirements

1. CMake 3.6 >
2. MSVC 14 >
3. Opt: ccache 4.x >

Building

git clone https://github.com/ValeriiKoniushenko/Nexium.git
cd Nexium
git submodule update --init --recursive --remote
cmake -S . -B build -G "Visual Studio 17 2022" -A x64
cmake --build build

Linux

Pre-requirements

1. You need to install the next components to build the project.

   sudo apt install libwayland-dev wayland-protocols libxkbcommon-dev \ 
    libxkbcommon-x11-dev libx11-dev libxrandr-dev libxinerama-dev \
    libgl1-mesa-dev pkg-config libxcursor-dev libxi-dev
   

2. CMake 3.6 >
3. Clang 22 >= or GCC 14 >=
4. Set git nuke alias and execute it after every checkout:
   • Linux shell:

     git config alias.nuke '!rm -f .jrm/cache.data && find -name '*.generated.*' -delete && git submodule sync --recursive && git submodule update --init --recursive --remote'

   • Windows PowerShell:

     git config alias.nuke '!powershell -NoProfile -Command "Remove-Item -Force -ErrorAction SilentlyContinue .jrm/cache.data; Get-ChildItem -Recurse -Filter '\''*.generated.*'\'' -File | Remove-Item -Force; git submodule sync --recursive; git submodule update --init --recursive --remote"'

5. Opt: ccache 4.x >
6. Opt: mold 2.x (linker)

Building

git clone https://github.com/ValeriiKoniushenko/Nexium.git
cd Nexium
git submodule update --init --recursive --remote
cmake -S . -B build
cmake --build build

Opt: 10x build speed

We will speed up ccache to increase the build speed. Populate the next config at your ccache.conf file. Default locations:

• Windows: %APPDATA%\ccache\ccache.conf
• Linux: ~/.config/ccache/ccache.conf

hash_dir = false
sloppiness = include_file_mtime,include_file_ctime,time_macros,locale
depend_mode = true
compression = true
max_size = 20G

Opt: 2x link speed (Linux)

# install 'mold' linker
sudo apt install mold

Documentation and demos

Take into account, due to active development, the real game & engine were not divided. So, now you can write your own game as a part of the engine. It will be fixed in the nearest future. Also, you can find a Demo Game in the root of the project under the name 'game-example'. After successfully building you can run it by the next path: <build_dir>/bin/TemplateGame.

About documentation: the same reason. After the first beta version, all documentation will be added here.
