Hediffs with Prerequisites

HediffCompProperties_PrerequisiteHediff can be used to make hediffs that require a certain other hediff to be implanted or to work. Similarly to disableable hediffs, replacementDef must contain HediffCompProperties_HediffRestorer comp that acts as a temporary holder.

    public class HediffCompProperties_PrerequisiteHediff : HediffCompProperties
    {
        public List<HediffDef> prerequisites;
        // List of genes that the pawn should have for the item to be equipped
        public List<GeneDef> genePrerequisites;
        // If hediff can be implanted without prerequisites
        public bool applyWithoutPrerequisites = false;
        // Wherever prerequisite hediffs must be located on the same bodypart
        public bool samePartPrerequisites = false;
        // If hediff should be disabled if one or multiple prerequisites are missing
        public bool disableIfMissing = true;
        //Def of a hediff that will replace this hediff upon being disabled
        public HediffDef replacementDef;
    }
