Source is a 3D game engine created by Valve, it is the successor to GoldSrc. Source has been used by Valve, third-party Companies, and much like GoldSource, it has been used in countless community mods by people around the globe.

Screenshot in-game of Counter-Strike: Source, using the Source Engine.
Screenshot taken in-game Counter-Strike: Global Offensive which currently uses a newer branch of the Source Engine.

Materials System

  • Instead of traditional textures, Source defines sets of materials that specify what the object is made from and the texture used for that object. A material specifies how an object will fracture when broken, what it will sound like when broken or dragged across another surface, and what that object's mass and buoyancy are. This system is much more flexible than other texture only based systems

    • Multiple players in a vehicle in multiplayer
    • Hovercraft support for cheaper simulation

Advanced AI

  • I/O system allowing level designers to control AI
  • Sophisticated navigation: characters that run, fly, jump, crouch, climb stairs and ladders, and burrow underground
  • AI senses things using sight, sound, and smell
  • AI relationships determine friend/foe status of other entities
  • Battle AI allows squads of AI characters to operate together, know when to advance, retreat, lay cover fire, etc.
