  • Fixed symlinks to Linux and MacOS builds of SDL2 #137 (Thanks MegaBrutal)
  • Deleted Makefiles and libraries for MacOS X (Half-Life 1 is 32 bit, no longer supported by MacOS) #141 (Thanks fel1x-developer)
  • Upgraded tool projects to use Visual Studio 2019, fixed as many warnings as possible, all tools aside from smdlexp compile, all tools compiled as C++, most tools work as intended #138 (Thanks fel1x-developer for helping with this work)
    • Fixed missing archtypes.h header include #136
    • Updated readme.txt for latest methods installing MFC, smdlexp and SDL2 #140 (Thanks fel1x-developer)
    • Removed obsolete VS6 & makefile project files from tools code #142
    • Removed bsplib.h & bsplib.cpp (redundant) #143
  • Added fgd/halflife.fgd
  • Cleaned up the Linux makefiles to remove obsolete logic and simplify the compilation process
  • Removed use of obsolete register keyword (caused compiler errors when using Clang++)
  • Added support for overriding the compiler used when using the Linux makefiles
  • Fixed the Linux makefiles not working when using Clang++ due to missing -mno-sse compiler flag
  • Added game icons for program icon and Steam library icon
  • Use post build event to copy dlls instead of using output directory #167
  • Added -flifetime-dse=1 flag to Linux Makefile to disable compiler optimization that removed entity memory zero-initialization, resulting in the game crashing when any entity touches the world #187 (Thanks FreeSlave)
  • Set maximum edicts to 2048 in liblist.gam #181
  • Made the Linux version link statically to the C++ runtime to help avoid problems when running mods on older systems (Thanks a1ba and FreeSlave)
  • Copy delta.lst when building client or server to ensure mods have correct delta.lst file (Thanks P38TaKjYzY)
  • Disabled GCC optimization that prevents mod dlls from unloading after engine calls dlclose
  • Fixed third party libraries possibly not being linked to when building Linux server dll (Thanks a1batross)
  • Mods made with this SDK will now shut down if they detect they are being run from a Valve game directory (e.g. by placing the dlls in Half-Life/valve/cl_dlls and Half-Life/valve/dlls). This is not supported and puts users at risk of being VAC banned. Run mods from their intended location only
  • Link Linux binaries with -Wl and --no-undefined flags to avoid situations where something was referenced but wasn't added in the build (Thanks a1batross)

Git repository changes

  • Added Github Actions CI configuration file based on Half-Life Unified SDK's version. Continuous Integration provides pre-built binaries for Windows and Linux. (Thanks to JoelTroch for providing the original file and providing the basis for this file)

Game installation

  • Added delta.lst and the resource directory to the game installation
  • Fixed HD Revolver model not playing the reload sound (halflife issue #2351)
  • Rewrote the installation and packing scripts to use C#
  • Added game icons to the game installation
