Compile Godot 2.x for Windows easily (with a script encryption key if necessary)

build_windows.bat

:: This script must be run from a Windows machine with
:: Visual Studio 2017, Python 2.7 and SCons installed at their
:: default locations. 7-Zip also needs to be installed (to compress editor binaries).
:: UPX: https://upx.github.io/

:: NOTE: You need Pywin32 to be installed to use multi-threaded compilation.
:: You may need to set "threads" to 1 for the first build, even if you have it installed.

:: Place this script at the root of your Godot Git clone.
:: CC0 1.0 Universal

:: Key for encrypt gdscript files while export
:: Generate key https://www.grc.com/passwords.htm
:: set SCRIPT_AES256_ENCRYPTION_KEY=INSERT_YOU_KEY_64_RANDOM_HEXADECIMAL_CHARACTERS_AND_UNCOMMENT

:: set threads=%NUMBER_OF_PROCESSORS%
set threads=1
