Trait Tracker Injector

File Type Script
Version 2.0.1
Last Update Jul 02, 2025

Description

Core Library

This script provides a shared core system used by other mods. It only needs to be installed if another mod explicitly requires it.

The Trait Tracker Injector (originally created by MAL22) is a specialized tool that enables the inheritance of custom traits across Sim generations. It allows traits to be passed from parents to offspring, making it possible to create unique family lines with inherited abilities, such as dormant occult traits or special skills.

Why this version?

After Patch 1.110, many mods—including the original Trait Tracker Injector—stopped working. Since the original version was no longer maintained, I stepped in to provide a fix for the community. I have completely reworked the script to resolve bugs introduced by the patch. All mods relying on this injector should now function correctly again without any extra steps from you.

A similar injector is now included in the Lot51 Core Library, which many modern mods have switched to. If a mod you use recently updated to require the Lot51 Core Library, you may no longer need this standalone injector. This fix is primarily for older or specific mods that still strictly rely on the original MAL22 syntax.

For Modders

The usage and syntax of this updated version remain entirely unchanged. You can continue to use it in your new projects exactly as described in the original documentation by MAL22, without having to modify your code or integration methods.

Language & Translations

This is a pure script-only mod and does not contain any package files or in-game text strings. Since it does not interact with the game UI or use localized strings, translations are neither possible nor required.
