Sims4Studio’s Tech Lead Andrew has posted a very useful tutorial on how to update all of your Script Mods for the upcoming update release for The Sims 4.
As warned by SimGuruModSquad about a month ago, the upcoming update for The Sims 4 will be upgrading the programing language used for some of the game’s basic functions from Python 3.3.5 to Python 3.7.0. This means that every single script mod created for the game will be completely obselete and won’t even be recognized by the game’s engine considering that the file extensions will switch from .pyo to .pyc.
Luckily, this tutorial will teach you how to easily upgrade your Script Mod and prepare it for the upcoming update.
This tutorial will show you how to install the required tools, extract EA python scripts, edit custom python scripts, and compile them to share as a mod. You will be using a free program called PyCharm to edit the python files. Please note, this tutorial assumes some familiarity with python and is not meant as a substitute for lessons/tutorials in python coding. It will show the Sims 4-specific steps of making a script mod.
