Unreal Public Source Distribution
Copyright
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.
Installation
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.
Tools Required
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 this package.
- C:\Unreal\MyPackage\Inc\*.h: Public C++ header files, which are exposed to
all other packages.
- C:\Unreal\MyPackage\Classes\*.upkg: UnrealScript package definition file.
- C:\Unreal\MyPackage\Classes\*.uc: UnrealScript class source files.
Directory Structure
- \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 support).
- \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.
