GoldSrc

"Powered by the Half-Life engine" logo used on some game boxarts.

GoldSrc (also known as GoldSource, and formerly just the Half-Life Engine) is a 3D video game engine created by Valve in 1996. It was the driving force behind many famous games of the late 90s and early 00s, such as Half-Life, Team Fortress Classic, Counter-Strike, and Day of Defeat. GoldSrc is a heavily modified version of the Quake engine, and runs on C++ programming code. GoldSrc and its level editor, Valve Hammer Editor, were released by Valve for public use, making it the source of countless community-made modifications.

GoldSrc was replaced by its sequel engine, Source, in 2004, which currently holds first place as the choice for modders. Though GoldSrc is past its prime, many gamers still seek to use it for mods and level design.

Bugs and Limitations

Important:Visit the Half-Life SDK GitHub repository in order to prevent duplicate or outdated bug reports on the wiki.

Bug:Overbright lighting (gl_overbright 1 is broken due to an OpenGL extension used for multi-texturing, which is required for the detail textures used by Counter-Strike: Condition Zero and Day of Defeat.

Workaround:See Overbright lighting section in PCGamingWiki's Half-Life page.

  [todo tested in ?]

Bug:On some systems running Windows Vista or later, the engine may suffering from extremely low frame rates during gameplay, especially on Intel iGPUs.

Workaround:

• Set the game (hl.exe) to "High Priority" in Task Manager.
• Disable multitexturing.

  [todo tested in ?]

Bug:EAX and A3D Audio are no longer supported since SteamPipe update in 2013. This also removes support for surround sound, and drastically impacts how certain DSP effects sound (such as buzzing noises on DSP's Weirdo 1-3).

Workaround:Use MetaAudio; see the Audio section on PCGamingWiki's Half-Life page.

Warning:Please note that using MetaAudio in VAC-protected multiplayer servers may cause a false positive, resulting in a ban. Use -insecure to disable VAC for local servers.

  [todo tested in ?]

Bug:Running any GoldSrc game over around 100-120FPS or higher can cause issues with movable objects (and prior to October 8, 2019 update, NPC turn rate) being slower or faster.  [todo tested in ?]

Features

Todo: expand here or add links

• AI flocking - NPCs can group together, seen with Houndeyes
• Skeletal animation - allowing for more stable animation of models, compared to the vertex animation in Quake
• Colored lighting - Quake simply had monotone lighting
• Scripted sequences - Used extensively to tell Half-Life's story
• Transparent textures - Glass can now be used in maps
• Higher poly counts - GoldSrc allows for far more detailed models than Quake

Half-Life SDK

Main article:  Half-Life SDK

As of August 2013, it is available on Steam under the "Tools" section. With it comes Hammer 3.4, the 3ds Max sources for many cut and retail NPCs as well as player and weapon models, tools for packing textures into WADs, and detailed documentation on implementing baseline features such as voice chat into a mod...

The full source code for the latest version of the SDK can be found on Valve's Github Page.

Note: Hammer 3.5 is the final GoldSrc-only editor released by Valve and can be downloaded separately.

Trivia

• The term "GoldSrc" comes from development of the Source engine. A few months before the release of Half-Life, the Half-Life engine's source code was split into two branches: Src and GoldSrc. The GoldSrc branch was the gold master version of the codebase, and would be used for the proper release of the game. The Src branch, comparatively, would be continually iterated upon, adding and changing features for use in the sequel, with the term "Source Engine" eventually being picked up by marketing.^[1]
