Source is a game engine from the US game developer Valve . It runs on both 32-bit and 64-bit systems. Games based on it have been published for Windows , macOS , Linux , Xbox , Xbox 360 and PlayStation 3 .
The engine was developed over five years (from around 1999 to 2004) for the game Half-Life 2 as a replacement for the proven Half-Life engine ( GoldSrc ). The main focus was on the greatest possible compatibility with the predecessor, in particular on the support of BSP cards. According to John Carmack , the engine contains code fragments from the Quake engine .
In addition to variable support for DirectX 7 to 9, the engine also includes a heavily modified version of the Havok - physics engine . It also supports Vertex Shader 3.0 and, since the end of October 2005, High Dynamic Range Rendering . Since the release of the Linux version of Team Fortress 2, which is based on the Source Engine, it has also been available under Linux.
Areas of application
The Source Engine is mainly used in Valve's own 3D shooters such as Half-Life 2 and Counter-Strike: Source / Global Offensive . This engine has recently also been used in the MOBA Dota 2 . In addition, the engine has also been licensed by other developers: For example, the 2004 Vampire: The Masquerade - Bloodlines uses this engine.
Valve has also re-released the older games Half-Life , Counter-Strike and Day of Defeat with the Source Engine - in contrast to the other two ports , Half-Life: Source was released without major changes to the original. As announced, only minor level details have been changed, but the game clearly benefits from the newer engine. Day of Defeat: Source has been given new textures and models so that it corresponds to the graphic level of Half-Life 2 and Counter-Strike: Source . In addition, some gameplay changes have been made to the original.
The Source Engine website is no longer available and the Source Engine can no longer be licensed.
Before setting the licensing no exact costs were by Valve publicly known, but only a vague description of the price, "extremely competitive prices" (German: extremely competitive prices ) specified. Offers to license the engine are subject to a confidentiality agreement .
At the Game Developers Conference 2015, the successor to the Source Engine, the Source-2-Engine, was announced. It is completely free, the condition is that the game must be published on Steam. An SDK for the Source 2 engine is currently not publicly available. Dota 2 by Valve, the developer of the Source Engine, is the first game to use the Source 2 engine. Until September 2015 it was based on the Source engine and was ported to the Source 2 engine as part of the reborn update. Half-Life: Alyx , another title in the Half-Life franchise, which was released on March 23, 2020, is also based on the Source-2 engine and comes with integrated level creation tools, which, however, do not have the full scope of a Source-2 SDK provides.
