An SDK-like projection of UnrealScript-accessible code for Mass Effect 1 (Legendary Edition)

Legendary Edition SDK

A collection of SDK-like projections of the Legendary Edition's codebase accessible to UnrealScript for Mass Effect 1, 2 and 3. Built with a version of UE3 SDK generator by TheFeckless, adapted by me to support 64-bit executables, multiple translation units, and BioWare's in-house SFXName system which replaces/extends the FName system.

Game versions

Executable versions the SDKs were built for - they need to be updated when the next patch drops.

• LE1 - 2.0.0.48602
• LE2 - 2.0.0.48602
• LE3 - 2.0.0.48602

How to use

• Create a buildable SDK library.
  • Create a VS C++ project for the SDK and ensure the following settings:
    • Project and Solution platforms must be x64.
    • General / Configuration Type = Static Library (.lib).
    • General / C++ Language Standard = ISO C++17 Standard (/std:c++17).
    • C/C++ / General / Multi-processor Compilation = Yes (/MP).
    • C/C++ / Language / Conformance mode = No (/permissive).
    • C/C++ / Precompiled Headers / Precompiled Header = Not Using Precompiled Headers.
    • Command Line / Additional Options = /bigobj.
  • Add .cpp SDK files into Sources so that VS compiles them, and .h SDK files into Headers.
    • Don't add any of PlotManagerDLC_*.* files, as they duplicate/override existing classes, which is impossible in C++.
• Create an ASI project.
  • Create another VS C++ project, for your ASI, with the same settings except for:
    • General / Configuration Type = Dynamic Library (.dll).
    • (recommended) Advanced / Target File Extension = .asi.
  • Right click on the new project, add reference to the library project above.
  • Add your plugin files, starting with an entry .cpp file which will either use SPI plugin system, or will have a DllMain() global function.
  • One way or another, your .cpp (and probably .h) files must include SdkHeaders.h from whichever SDK you are using.
• Before using any part of the SDK in code, run SDKInitializer::Instance() and make sure that the pointers returned by that object's GetBioNamePools() and GetObjects() are valid and make sense.
