List<Custom> IExposable and PostExposeData

[ethouiche]

Hello,

I have a comp class that uses another class as a list. I cant manage to save properly the list generated in the comp class. I have used many ExposeData before but never with a list. I need this list.

public class LTF_PawnSnapshot : IExposable
{
        // should send a signal to bench when dies instead of benchscan
        public Pawn original;

        public string pawnThingId;
        public string name;

        public float ageBiological;
        public Gender sex;

        //long ageChronological;
        public List<Hediff> hediffs;
        public List<SkillRecord> skills;


        //Race though
        public int cloneNum;
        public int AAA;

        public Building drillDep;

        public float buildProgress;
        public float buildAmount;

        public void ExposeData()
        {
            Scribe_References.Look<Pawn>(ref original, "LTF_snapOriginal");

            Scribe_Values.Look<string>(ref pawnThingId, "LTF_cloneOriginalId");
            Scribe_Values.Look<string>(ref name, "LTF_cloneOriginalName");

            Scribe_Values.Look< float>(ref ageBiological, "LTFOriginalAge");
            Scribe_Values.Look<Gender>(ref sex, "LTFOriginalSex");

            Scribe_Collections.Look<Hediff>(ref hediffs, "LTFOriginalHediff");
            //Scribe_Collections.LookList<Hediff>(ref hediffs, "LTFOriginalHediff");
            Scribe_Collections.Look<SkillRecord>(ref skills, "LTFOriginalSkill");
           
            Scribe_Values.Look<int>(ref cloneNum, "LTFcloneNum");
            Scribe_Values.Look<int>(ref AAA, "LTFcloneAAA");

            Scribe_References.Look<Building>(ref drillDep, "LTF_drillDep");

            Scribe_Values.Look<float>(ref buildProgress, "LTF_cloneWProgress");
            Scribe_Values.Look<float>(ref buildAmount, "LTF_cloneWAmount");
        }
    }

The comp Class with the list;

Code Select Expand

        // Scanned
        List<LTF_PawnSnapshot> RegisteredPawns = new List<LTF_PawnSnapshot>();
[...]


Code Select Expand

        public override void PostExposeData()
        {
            base.PostExposeData();

            //Scribe_Collections.Look(ref RegisteredPawns, "LTF_snaps", LookMode.Undefined, new object[0]);

            //Scribe_Deep.Look(ref RegisteredPawns, "LTF_snaps");
            //Scribe_Collections.Look(ref RegisteredPawns, "LTF_snaps",LookMode.Reference);
            //Scribe_Collections.Look(ref RegisteredPawns, "LTF_snaps", LookMode.Deep);
            //Scribe_Collections.Look<LTF_PawnSnapshot>(ref RegisteredPawns, "LTF_snaps", LookMode.Deep);
            //update

        }

I have tried many options without success. I really feel i have no idea what i am doing. I have cast errors either when i load or when i save.

Please be my savior.
Good day.

You might have more luck if you could upload the mod so we can run it and see what happens for our self.

I have been told the game does not know how to handle/save the hediff data because it's not attached to a pawn.

By using a pawn to handle the hediff it seems the save works fine.
