Xash3D (pronounced [ksɑʂ]) FWGS is a game engine, aimed to provide compatibility with Half-Life Engine and extend it, as well as to give game developers well known workflow.

Xash3D FWGS is a heavily modified fork of an original Xash3D Engine by Unkle Mike.

Fork features

Steam Half-Life (HLSDK 2.5) support.
Crossplatform and modern compilers support: supports Windows, Linux, BSD & Android on x86 & ARM and many more.
Better multiplayer: multiple master servers, headless dedicated server, voice chat, GoldSrc protocol support and IPv6 support.
Multiple renderers support: OpenGL, GLESv1, GLESv2 and Software.
Advanced virtual filesystem: .pk3 and .pk3dir support, compatibility with GoldSrc FS module, fast case-insensitivity emulation for crossplatform.
Mobility API: better game integration on mobile devices (vibration, touch controls).
Different input methods: touch and gamepad in addition to mouse & keyboard.
TrueType font rendering, as a part of mainui_cpp.
External VGUI support module.
PNG & KTX2 image format support.
Ogg Vorbis (.ogg) & Ogg Opus (.opus) audio formats support.
A set of small improvements, without broken compatibility.

Installation & Running

Get Xash3D FWGS binaries: you can use testing build or you can compile engine from source code.
Copy engine binaries to some directory.
Copy valve directory from Half-Life to directory with engine binaries. If your CPU is NOT x86 compatible or you're running 64-bit version of the engine, you may want to compile Half-Life SDK. This repository contains our fork of HLSDK and restored source code for Half-Life expansions and some mods. You still needed to copy valve directory as all game resources located there.
Run the main executable (xash3d.exe or AppImage).

For additional info, run Xash3D with -help command line key.

Build instructions

We are using Waf build system. If you have some Waf-related questions, I recommend you to read Waf Book.

NOTE: NEVER USE GitHub's ZIP ARCHIVES. GitHub doesn't include external dependencies we're using!

Prerequisites

If your CPU is x86 compatible and you're on Windows or Linux, we are building 32-bit code by default. This was done to maintain compatibility with Steam releases of Half-Life and based on it's engine games. Even if Xash3D FWGS does support targetting 64-bit, you can't load games without recompiling them from source code!

If your CPU is NOT x86 compatible or you decided build 64-bit version of engine, you may want to compile Half-Life SDK. This repository contains our fork of HLSDK and restored source code for Half-Life expansions and some mods.

Windows (Visual Studio)

Install Visual Studio.
Install latest Python OR run cinst python.install if you have Chocolatey.
Install latest Git OR run cinst git.install if you have Chocolatey.
Download SDL2 development package for Visual Studio.
Clone this repository: git clone --recursive https://github.com/FWGS/xash3d-fwgs.
Make sure you have at least 12GB of free space to store all build-time dependencies: ~10GB for Visual Studio, 300 MB for Git, 100 MB for Python and other.

GNU/Linux

Debian/Ubuntu

Only for 32-bit engine on 64-bit x86 operating system:
- Enable i386 on your system: $ sudo dpkg --add-architecture i386.
- Install aptitude (why?): $ sudo apt update && sudo apt upgrade && sudo apt install aptitude
- Install development tools: $ sudo aptitude --without-recommends install git build-essential gcc-multilib g++-multilib libsdl2-dev:i386 libfontconfig-dev:i386 libfreetype-dev:i386 libopus-dev:i386 libbz2-dev:i386.
- Set PKG_CONFIG_PATH environment variable to point at 32-bit libraries: $ export PKG_CONFIG_PATH=/usr/lib/i386-linux-gnu/pkgconfig.
For 64-bit engine on 64-bit x86 and other non-x86 systems:
- Install development tools: $ sudo apt install git build-essential python libsdl2-dev libfontconfig-dev libfreetype6-dev libopus-dev libbz2-dev.
Clone this repostory: $ git clone --recursive https://github.com/FWGS/xash3d-fwgs.

RedHat/Fedora

Only for 32-bit engine on 64-bit x86 operating system:
- Install development tools: $ sudo dnf install git gcc gcc-c++ glibc-devel.i686 SDL2-devel.i686 opus-devel.i686 fontconfig-devel.i686 freetype-devel.i686 bzip2-devel.i686.

Building

Windows (Visual Studio)

Open command line.
Navigate to xash3d-fwgs directory.
(optional) Examine which build options are available: waf --help.
Configure build: waf configure --sdl2=c:/path/to/SDL2.
Compile: waf build.
Install: waf install --destdir=c:/path/to/any/output/directory.

Linux

If compiling 32-bit on amd64, make sure PKG_CONFIG_PATH from the previous step is set correctly, prior to running configure.

(optional) Examine which build options are available: ./waf --help.
Configure build: ./waf configure (you need to pass -8 to compile 64-bit engine on 64-bit x86 processor).
Compile: ./waf build.
Install: ./waf install --destdir=/path/to/any/output/directory.
