Unreal Public Source Distribution

This is the public distribution of the Unreal source for advance mod authors wanting to make C++ mods.

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.
