3D Real Time Strategy video game GL port source code Released as a free software under a permission of Night Dive Studios who owns the rights to the game.

Community fork

This version of the game is a community fork. It is purposely different from the original source code, which is available here.

Changes

The most notable changes are:

• Added support for 2X UI scaling
• Added keyboard shortcuts
• Fixed various LAN game issues
• Fixed tens of bugs
• Fixed a dozen of crashes

Windows builds are now done automatically by GitHub.

Installation

Windows

1. Download https://download.wiredforwar.org/Game/Community-Build-1.5/machines-assets.7z. The archive has machines directory inside.
2. Extract the archive (machines-assets.7z) to the wanted installation directory.
3. Open https://github.com/WiredForWar/machines/releases and download machines-win64-wfw-%releasedate%.7z from the assets of the latest release. E.g. release v1.7.1 has machines-win64-wfw-20240910.7z in its Assets. The downloaded win64 archive also has machines directory inside.
4. Extract the archive (machines-win64-wfw-%releasedate%.7z) to the same installation directory and overwrite the existing files (the win64 archive has new version of some assets).

Note: if you don't have machines.exe inside the extracted machines then maybe you've extracted the second archive into the first, which resulted in machines/machines/machines.exe. In order to get a correct installation, try to redo the steps from #2, this time make sure that you've extracted both archives into the same directory.

GNU/Linux

Note: the latest information about installation and troubleshooting is available at https://github.com/WiredForWar/machines/wiki/Linux.

Flatpak

Use Flatpak to install the client (only amd64 for now):

flatpak install --user https://wiredforwar.github.io/flatpak/wiredforwar-machines.flatpakref

or just open the linked file https://wiredforwar.github.io/flatpak/wiredforwar-machines.flatpakref with default Flatpak frontend. Flatpak (the manager) installation howto: https://flatpak.org/setup

Providing the assets

After the installation but before the first run (you can try to run but the game won't start), download the assets from https://lordovervolt.com/machines (e.g. http://markol.usermd.net/machines/machines-assets.7z or https://download.wiredforwar.org/Game/Community-Build-1.5/machines-assets.7z) and extract them to ~/.var/app/io.github.wiredforwar.machines/data/, so there are sounds and other assets inside the ~/.var/app/io.github.wiredforwar.machines/data/machines/data/machines directory.

:warning: The directory does not exist before the first run. Don't worry and just create it manually (like in the first line of the script below).

Here is a short script doing that for you:

mkdir -p ~/.var/app/io.github.wiredforwar.machines/downloads
cd ~/.var/app/io.github.wiredforwar.machines/downloads
wget https://download.wiredforwar.org/Game/Community-Build-1.5/machines-assets.7z
7z x machines-assets.7z -o../data

Then you can run the game normally (e.g. via desktop menu). Flatpak command to run the game is:

flatpak run io.github.wiredforwar.machines

On an update released you can use your preferred Flatpak frontend or install the update via console:

flatpak update io.github.wiredforwar.machines

Logs

The logs are in ~/.var/app/io.github.wiredforwar.machines/logs, and the save files are in ~/.var/app/io.github.wiredforwar.machines/savegame.

Development

Followed conventions

The main code is spilt into a set of libraries:

• afx - SDL app window creation, string resources handling,
• ani - smacker animations,
• base - compiler type things, new and delete overloaded global operators, leak and stack tracker (not used), persistence and logging mechanisms,
• ctl - charybdis template library - this was created to improve STL functionality, now it is a wrapper around gnu stl - note it uses public inheritance from std containers, found no problems yet? Only ctl containers support persistence,
• device - mice, keyboards, timers, (back when they did that stuff and didn't just rely on direct x), cd audio (music track),
• envirnmt - maps, sky loading code,
• gui - base classes for gui concepts (buttons, list, scrolling dialog windows and such like),
• gxin - parser for old .agt text format meshes,
• machgui - the real machines based UI,
• machlog - the logic stuff, AI, choosing levels and such like,
• machphys - the renderable bits of machines (agressors, administrators, mines, etc),
• mathex - maths libraries,
• network - low level communication layer,
• phys - base classes of some physics types things - this is NOT real time physics - by how to fiddle it,
• profiler - not used now,
• recorder - allows to record and replay all the in game activity, events, random seeds etc. Game works in single thread, useful when reproducing a bug (not checked if it works),
• render - base library for rendering primitives, triangles, meshes, textures, materials, surfaces, etc,
• sim - base classes for things that can be simulated,
• sound - loading and playing wave samples 2D/3D,
• stdlib - now a little has left from it (there was cout, cerr, etc ),
• system - mostly file device handling, msgbox, metafile, registry (xml config),
• utility - helpers of various types, e.g. file parsers. again a lot of this stuff you wouldn't bother with now but back then there was no source forge or even google,
• world4d - built on top of the render libraries, turned basic rendering into multi-mesh entities (W4dEntity is a base class for lot of things),
• xin - .X mesh file loading into game engine (added now),

Build dependencies

Use provided Docker image for building or manually setup your environment.

libsdl2-dev libsdl2-image-dev libopenal-dev libenet-dev libfreetype6-dev libglew-dev libglm-dev libaudio-dev libswscale-dev

Building

For Windows on linux/docker

sudo apt-get install mingw-w64
mkdir buildMingw64 && cd buildMingw64
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-mingw64.cmake ..

or 32-bit cpu:

mkdir buildMingw32 && cd buildMingw32
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-mingw32.cmake -DBUILD_32=1 ..

Extra parameters for release optimizations: -DCMAKE_BUILD_TYPE=RELEASE -DDEV_BUILD=OFF

For GNU/Linux

• mkdir build && cd build
• cmake ..
• cmake --build . -j 9

With Conan (e.g. for Windows/MSVC)

Dependencies can be provided by Conan 2 instead of system packages, using the bundled cmake-conan dependency provider. This is the recommended way to build with MSVC.

Prerequisites: pip install conan and a one-time conan profile detect.

cmake -S . -B build -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES=cmake/conan_provider.cmake
cmake --build build

Missing binary packages are built from source on the first configure (subsequent configures use the local Conan cache). If conan is not on PATH, pass -DCONAN_COMMAND=<path/to/conan>.

For ARM SoC development boards (like Raspberry or Nitrogen8M) if you do not have cross compilation toolchain prepared it will be easier to boot-up one of dedicated system distribution and build it within this enviroment (takes approx one hour for 4 cores).

Making a package

Run make package to collect all of the data files, graphics files, and compiled binaries into a single package file. You may then copy the contents of the package into your game's directory.

Debugging

Class invariant checks

export CB_INVARIANT_CHECKING=on

Debug streams

To turn on a stream define environment variable with correct name, eg. set CB_HAL_TO=cout or in linux shell export CB_HAL_TO=cout. Target cout is a current shell of course, replace it with filename to write log into or leave empty to turn off.
