Adding Overdose Immunity to Chemical Dependency Genes

[PamboS]

Hi there, first time RimWorld modder here.

I'm trying to modify the default Chemical Dependency genes (such as Wake-up dependency) to also provide a 0% overdose chance factor, similar to what Wake-up Impervious provides.

I've looked at how the GeneChemicalBase class is defined in RimWorld/Data/Biotech/Defs/GeneDefs/GeneTemplateDefs.xml but unlike addictionChanceFactor, which affects the probability of getting addicted to the drug, I can't figure out a way to also modify overdoseChanceFactor -- this parameter doesn't seem to be accepted by the class so I presume that overdose immunity is defined/processed somewhere else.

Any suggestions would be highly appreciated!

Below I copied the relevant code I'm looking at from GeneTemplateDefs.xml:

In the C# class RimWorld.GeneTemplateDef exists no field called "overdoseChanceFactor".
Thats why the game complains when you try to add the xml tag to the GeneTemplateDef.

But it exists in the class Verse.GeneDef, thats why you can add it to GeneDefs.

As I dont know much about Biotech and dont know how the gene system works, I unfortunately cant help you any further.

Got it, thanks for the reply!
