Unreal Public Source Distribution
All files contained here are the property of Epic
Games, Inc. They are provided without warranty, and under the same terms as the
Unreal retail license agreement: You may use them for your personal, non-profit enjoyment,
but you may not sell or otherwise commercially exploit the source or things you created
based on the source.
Unzip the source distribution into your root Unreal directory, for example c:\Unreal.
You must use the exact same version of Unreal patch and public source
distribution. If you have different versions, then the DLL's you recompile with the
source distribution will almost certainly fail to run.
To recompile the source, you must have Microsoft Visual C++ 6.0, either with no service
packs, or with SP1. The source does not work with previous versions of Visual
C++. The source may or may not work with subsequent versions and service
packs. If you are using anything other than this exact version, don't even think
about emailing us asking why it doesn't work.
How Each Package (.DLL) Is Structured
Unreal packages are described in detail in the Package Documentation. The
source code for each package (for example, MyPackage) that contains a C++ .DLL component
is as follows:
- C:\Unreal\MyPackage\Src\MyPackage.dsp: Microsoft Developer Studio project files.
- C:\Unreal\MyPackage\Src\*.cpp: C++ source code.
- C:\Unreal\MyPackage\Src\*.h: Private C++ header files, which are only used internally by
- C:\Unreal\MyPackage\Inc\*.h: Public C++ header files, which are exposed to all other
- C:\Unreal\MyPackage\Classes\*.upkg: UnrealScript package definition file.
- C:\Unreal\MyPackage\Classes\*.uc: UnrealScript class source files.
- \Unreal\UnrealPubSrc.dsw: Microsoft Visual C++ workspace file.
- \Unreal\Core: Unreal engine core components (non-game code, such as low-level object
handling, script interpretter, file processing, configuration, and platform-specific
- \Unreal\Engine: Unreal engine game components.
- \Unreal\Setup: Unreal Windows installer/uninstaller (Setup.exe).
- \Unreal\GlideDrv: Unreal Glide support. Note: To compile this code, you need the
latest version of the Glide SDK from 3dfx's web site.
- \Unreal\Help: A small amount of documentation.
- \Unreal\Launch: Unreal Windows startup code (Unreal.exe).
- \Unreal\OpenGLDrv: Unreal's OpenGL support.
- \Unreal\System: Unreal's system directory.
- \Unreal\UCC: Platform-neutral command line runner. Launches "commandlets" such
as the script compiler, installation generator, and command-line server.
- \Unreal\Window: Windows encapsulation.
