The Source SDK is a collection of tools used for developing content for the Valve's Source engine. Along with the packaged tools, the SDK also includes source code for the game server (game logic) and client, which allows creation of entirely new games on the engine.
Overview[]
The Source SDK contains many programs useful for editing and creating Source-based game content. It also contains the source code for Half-Life 2, which can be edited to create a mod or used as a base for an entirely different game.
Currently, the SDK supports two versions of the Source engine: the version used in Half-Life 2: Episode One and the one used in The Orange Box.
Between March 2008 - August 2009, Tony Sergi was updating the SourceSDK.[1]
Tools[]
The SDK is made up of various tools, some of which are accessible from a menu. The major tools are listed below.
Map Editor[]
The Hammer World Editor is used to design and script maps used in games and mods. It allows the user to create brushes of various shapes and model them accordingly, as well as place and control entities via the I/O scripting system.
Face Poser[]
Face Poser is the tool used to access and sequence facial animations and choreograph scenes. It is used to create in-game animation sequences, and for adding dialogue to maps.
This tool is used to:
- Edit facial expressions, gestures and movements for characters (called "actors"), allowing one to mix or blend several expressions on the fly.
- Lip-synch speech with the speech the characters use (and blend the speech with other facial expressions). The phonemes used for lip-synching can be extracted from existing spoken .wav files, the tool taking care of the real-time association between the spoken phonemes and the movements of the lips.
- Sequence expressions and other acting cues and preview what the scene will look like in the game engine. A scene can refer to multiple actors and thus can be used to block out fairly complicated interactions and dialogue between game characters.
Model Viewer[]
The Model Viewer is a program that allows users to view models.
The Model Viewer is primarily used for viewing models. It has the option to show just the model, with various adjustments such as shadows and texture options, however there are options to view models with their corresponding animations, attachment points, bones, and other features.
Other tools[]
The SDK also contains tools that can only be accessed via the program folder. studiomdl.exe
is used for creating models to be used in Source games. bspzip.exe
packs content into the finalized map file so that it is extracted on run. vtex.exe
converts image files into Valve Texture Files and Valve Material Files (.vtf
and .vtm
).
Trivia[]
In the playable Half-Life 2 Beta, some tools used in Half-Life, such as the Half-Life Dedicated Server, are mixed in with the tools used in the final Source SDK.
