Summary

The goals of this effort are to modernize the codebase, simplify the build system, and to improve performance. The game engine itself will eventually be moved off of the rendering thread, which will provide for a much more responsive user interface, particularly when many units are on the map.

All builds are now being done through CMake with regular testing on Windows with Visual Studio 2019 and Ubuntu with g++. Windows development is being done with VS2019's native CMake support, which uses Ninja for the actual build. (It is unknown if the CMake Visual Studio generators produce usable vcxproj files.)

Notable Changes

  • Builds are done with CMake (and only CMake).
  • ENet and libfmt have been updated are are no longer a normal part of the tree but are included as Git submodules instead.
  • vcpkg is used to provide SDL2, gtest, fmt, and ms-gsl.
  • Pausing after the mission has completed but before the statistic page is displayed will let the user explore the map for as long as they like.
  • On Windows, DirectX 11 is now the preferred renderer. An option has been added to the INI file to configure the preferred renderer. Add Renderer = direct3d or Renderer = software under the [Video] section to request SDL2's DX9 or software renderer, respectively.
  • A texture atlas (sprite-sheet) is created during startup that drastically reduces the number of texture switches during rendering. Some more work needs to be done for it to not fail when faced with an older GPU. To improve startup times, these texture atlases should probably be cached on disk.
  • Screen/windows managment has been changed to allow a window to be used over a Remote Desktop (RDP) session. Disconnecting and reconnecting RDP should no longer cause a hang.

At some point, some of these change might be incorporated into the upstream repository.

Known Issues

  • The random number generator is different than the one in the official release.
  • Systems with older GPUs may need to use the software renderer (add Renderer = software under the [Video] section in the INI file).
  • With all the rendering changes, there are now some glitches that need to be tracked down.

Building

Windows

Install Visual Studio 2019 including the "Desktop development with C++" workload. Go to the "Individual Components" of the installer to make sure "C++ CMake tools for Windows" is enabled (enable clang as well to enable builds with "clang-cl").

To build from inside Visual Studio, open the "dunelegacy" folder, go to the menu to select "Project" -> "CMake Settings for dunelegacy", and create a release configuration, set it as the current configuration, then select "Build" -> "Build All". It should be possible to open the repository directly by going to "File" -> "Clone Repository..." on the menu.

From the command line (a bit faster, but requries more typing):

First open a command prompt with access to CMake (for example, "Developer Command Prompt for Visual Studio 2019"). Get a copy of the code repository, along with the submodules:

git clone https://github.com/henricj/dunelegacy.git
cd dunelegacy
git submodule update --init --recursive -j 8

Build the vcpkg packages,

IDE\VC\vcpkg\build_vcpkg.bat

Configure CMake's build folder, compile the source, and run the tests (alas, there are far too few tests):

mkdir out\build\x64-avx2-Release
cd out\build\x64-avx2-Release
cmake -G Ninja -DCMAKE_BUILD_TYPE:STRING=Release -DDUNE_TARGET_ARCHITECTURE:STRING=x64 -DDUNE_TARGET_ARCHITECTURE_EXTENSION=avx2 -DVCPKG_TARGET_TRIPLET:STRING=x64-avx2-windows-ltcg ../../..
cmake --build .
ctest

There should now be a working dunelegacy executable in out\build\x64-avx2-Release\src.

Linux

The build-essential, git, ninja-build, and cmake packages are needed. Either g++ or clang can be used for the build (tested with g++-10 and clang-10).

git clone https://github.com/henricj/dunelegacy.git
cd dunelegacy
git submodule update --init --recursive -j 8

Build the vcpkg packages,

IDE/VC/vcpkg/build_vcpkg.sh

(At some point, the vcpkg folder will move to the externals folder where it belongs.)

Configure CMake's build folder, compile the source, and run the tests (alas, there are far too few tests):

mkdir -p out/build/x64-Release
cd out/build/x64-Release
cmake -G Ninja -DCMAKE_BUILD_TYPE:STRING=Release -DVCPKG_TARGET_TRIPLET:STRING=x64-linux ../../..
cmake --build .
ctest

There should now be a working dunelegacy executable in out/build/x64-Release\src.

Notes

Builds for macOS have not been tested, but should be similar to the Linux instructions.

IMPORTANT: This software is provided as is, and you are running it at your own risk. I'm not responsible if any harm results from you aquiring, or running this software. If you distribute this software, make sure this readme file is included. The program Dune Legacy is an modernized clone of the excellent Westwood Studios game "Dune 2". It is ridiculusly easy to find Dune2 on the net anyways, but I won't provide it. I think you can still even buy it from Westwood studios, so do that. There exists a mod called Superdune 2. The PAK-Files Superdune 2 provides are nearly the same except SCENARIO.PAK.

This program would not have been created without the use of the excellent SDL library and its extensions. Thanks guys :).

Getting Started

The following PAK-files from the original Dune 2 are needed to play Dune Legacy:

  • HARK.PAK
  • ATRE.PAK
  • ORDOS.PAK
  • ENGLISH.PAK
  • DUNE.PAK
  • SCENARIO.PAK
  • MENTAT.PAK
  • VOC.PAK
  • MERC.PAK
  • FINALE.PAK
  • INTRO.PAK
  • INTROVOC.PAK
  • SOUND.PAK
  • GERMAN.PAK (for playing in German)
  • FRENCH.PAK (for playing in French)

It depends on your system and installation where to put these files. LEGACY.PAK is supplied with Dune Legacy and is already in the data directory. All the other files should be copied there too. If you are not allowed to copy files there you may copy these files inside the dunelegacy configuration directory (e.g. ~/.config/dunelegacy/data/ on unix).

Linux

It depends on how the game was compiled. Normally you should put these files under /usr/share/dunelegacy/ or /usr/local/share/dunelegacy/ . Just look for LEGACY.PAK. If you do not have root access to your system you should put them in your home directory under ~/.config/dunelegacy/data/ .

Windows

The installer has already asked for the files and put them in the installation directory. If not put the PAK-files inside your installation folder or if you do not have administrator privileges you should put them to C:\Documents and Settings<YourName>\Application Data\dunelegacy\data\ .

MAC OS X

The PAK-files have to be copied inside the application bundle. If you have followed the steps in the supplied dmg you have already copied them there. Otherwise just right-click on the bundle and select "Show Bundle Content". Then navigate into "Contents" and then into "Resources". There you will find LEGACY.PAK. Put the other PAK-files there too. Alternativly you can put them in your home directory under ~/.config/dunelegacy/data/ but putting them inside the application bundle is the preferred way.

Configuration file

If you want to fine tune the configuration of Dune Legacy you might want to take a look at the configuration file "Dune Legacy.ini". Depending on your system it is either placed in ~/.config/dunelegacy (on Linux), ~/Library/Application Support/Dune Legacy (on Mac OS X) or in C:\Documents and Settings<YourName>\Application Data\dunelegacy\ (on Windows).

Internet Game

To play online via Internet you have to manually enable port forwarding if you use a NAT Router. Forward the Dune Legacy Server Port (Default is 28747) from your NAT Router to your computer. Use the same port on your router as configured in Dune Legacy. Example: If your machine has IP 192.168.123.1 and your using the default Dune Legacy Port, than forward port 28747 from your router to 192.168.123.1:28747.
