#CUSTOM QUAKE ENGINES CODE#

Valve released versions of the GoldSrc engine for OS X and Linux in 2013, eventually porting all of their first-party games using the engine to the platforms by the end of the year. Eventually, 'GoldSrc' became something of a moniker for the engine and was adopted as the official title externally.

Internally, any games using the original branch were referred to as 'Goldsource' to differentiate it from the second branch, which evolved into the Source engine.

#CUSTOM QUAKE ENGINES CODE#

When the need arose for Valve to work on the engine without risking introducing bugs into Half-Life 's codebase, Valve forked the code from the Half-Life engine, creating two main engine branches: one gold master branch titled 'GoldSrc' and the other 'Src'. Prior to the creation of the Source engine, the GoldSrc engine had no real title and was simply called 'The Half-Life engine'. The engine supports skeletal animation, which allowed for more realistic body kinematics and facial expression animations than most other engines at the time of release. The tool was later renamed to Valve Hammer Editor and became the official mapping tool for GoldSrc. In 1997, Valve hired Ben Morris and acquired Worldcraft, a tool for creating custom Quake maps. The engine also reuses code from other games in the Quake series, including QuakeWorld and Quake II, but this reuse is minimal in comparison to that of the original Quake.

GoldSrc's artificial intelligence systems, for example, were essentially made from scratch. While the engine served as the basis for GoldSrc, Gabe Newell has stated that a majority of the code used in the engine was created by Valve themselves. The basis of GoldSrc is the engine used in the video game Quake, albeit with heavy modification by Valve. However, Valve continues to support the engine with periodic updates. GoldSrc was succeeded by the Source engine with the releases of Half-Life: Source, Half-Life 2, and Counter-Strike: Source in 2004.

It originally made its debut in 1998 with Half-Life, and would power future games developed by or with oversight from Valve, including Half-Life 's expansions, Day of Defeat, and multiple games in the Counter-Strike series. At its core, GoldSrc is a heavily modified version of id Software's Quake engine. GoldSrc (pronounced 'gold source'), sometimes called the Half-Life Engine, is a proprietary game engine developed by Valve.
