UnrealEngine PythonSDK

An UnrealEngine Plugin enabling using Python to write plugins that interact directly with UE objects

List of compatible games

  • Borderlands 2 (1.8.7)
  • Borderlands: The Pre-Sequel!


Begin by downloading the latest version of here.

For PythonSDK to be able to interact with the game, you must add a few things to the game's Win32 folder. If you already have PluginLoader installed, you'll need to overwrite some files.

  1. Quit the game if it is running.

  2. Extract all of the contents of into your Borderlands 2\Binaries\Win32 directory.
    If you are asked to overwrite any files, accept. This mod replaces (and functions the same as) c0dy's Plugin Loader.

  3. If you have installed an older version of the SDK, delete the old files. This includes Win32\Plugins\PythonSDK.dll

Linux (SteamPlay/Proton and Wine)

PythonSDK does not yet work natively on Linux, but it seems to work well under SteamPlay/Proton and Wine. To load properly, though, Wine needs to be told to allow ddraw.dll overrides. Additionally, the latest SDK release (as of February 29, 2020) wants the main executable name to be Borderlands2.exe, so the common workaround of a Launcher.exe symlink/copy won't do the trick. Instead, set the game's launch options (via Properties -> General) to:

WINEDLLOVERRIDES="ddraw=n,b" bash -c 'exec "${@/Launcher.exe/Borderlands2.exe}"' -- %command%

Note that using WINEDLLOVERRIDES for ddraw isn't supported by the Wine developers, so if you experience problems with the game while using this method, please don't ask the WineHQ team for assistance.


py <python code> runs arbitrary python code.
pyexec <python file> runs arbitrary python files from binaries/Win32/Mods/.
