Which kinds of tweak records exist? How are they defined? What do they mean?

Summary

Created: Jan 13 2024 by mana vortex Last documented update: Jan 13 2024 by mana vortex

This page lists types of tweak records with their properties and lists of occurrences in the wild. They are grouped by type. If this wiki has more information, there will be a link at the start of the block.

This is a work in progress, as the tweak database is huge and barely-documented. If you have any information that needs to be in here, please don't hesitate to sign up as an editor and start contributing!

If you just want a quick overview of a certain type of tweak, you can check Cheat Sheet: Tweaks instead.

If you want to learn how to make tweaks instead, check How to YAML: Tweak modding basics

An effector is the tweak version of an if-condition: it is using Conditions or Prereqs before triggering its effect.

mods_abilities.tweak

{
    prereqRecord = "Prereqs.ProcessHitTriggered";
    percentMult = 0.25f;
    unitThreshold = 10f;
} : MultiplyDamageWithVelocity, 
{
    prereqRecord = "Perks.IsHitQuickMelee";
    value = 1.5f;
} : MultiplyDamage
