Those values do what?
<surgeonSurgerySuccessChanceExponent>
<roomSurgerySuccessChanceFactorExponent>
<surgerySuccessChanceFactor>
<deathOnFailedSurgeryChance>

How do you get the real success/failure chance?

take all factors and account?

if you want static rolls, like fixed 50% chance, you will need custom surgery implementation, in other case you will hit nan exception.

<surgeonSurgerySuccessChanceExponent> If i set this value to 2 it will increase success chance by 2% * medicine skill?
<roomSurgerySuccessChanceFactorExponent> If i set this value to 2 it will increase success chance by 2%?

No one know this?

Also the medicine/beds/medical level affect surgerySuccessChanceFactor if the above is not set?

will your computer explode and evaporate 100 km around if you test it self?

Kinda hard to test chances. For that i have to load a game and do the surgery at least 100 times to get a valid % result.
This X all the 4 fields.

just make the value 100 and 0 and 50 and test it 10 times each is simpler and shoud work but how you told 100x 1 is better.

I am kinda wondering about various chances in the game as well, just learning defs. Is there an easy way to display rolls in the console, to see the chance rolls and extra info? Or do I need to look into code to check it out, and there is no way to just toggle "logging" in the game itself? Sorry if the question is too simple/stupid, I am still kinda lost :).

Any results yet?
I'm too curious what those values mean.
Especially the first ones:

<surgeonSurgerySuccessChanceExponent>
<roomSurgerySuccessChanceFactorExponent>

<roomSurgerySuccessChanceFactorExponent>

<surgeonSurgerySuccessChanceExponent> is used in default game "Remove carcinoma".
i THINK its the base % of surgery success + the bonus of medicine level, medicines used and room bonuses stack with this.

If you doesnt use this the surgeries still can fail, so i guess there is a default unknown value for this.

<roomSurgerySuccessChanceFactorExponent>
I THINK its a bonus % of surgery success based on the room (sterile floor).

I found this piece of code while digging in the Assembly

using System;
using System.Collections.Generic;
using UnityEngine;
using Verse;

namespace RimWorld
{
public abstract class Recipe_MedicalOperation : RecipeWorker
{
//
// Static Fields
//
private const float CatastrophicFailChance = 0.5f;

//
// Methods
//
protected bool CheckSurgeryFail (Pawn surgeon, Pawn patient, List<Thing> ingredients)
{
if (surgeon == null) {
Log.Error ("surgeon is null");
return false;
}
if (patient == null) {
Log.Error ("patient is null");
return false;
}
float num = 1f;
float num2 = surgeon.GetStatValue (StatDefOf.SurgerySuccessChance, true);
if (num2 < 1f) {
num2 = Mathf.Pow (num2, this.recipe.surgeonSurgerySuccessChanceExponent);
}
num *= num2;
Room room = surgeon.GetRoom ();
if (room != null) {
float num3 = room.GetStat (RoomStatDefOf.SurgerySuccessChanceFactor);
if (num3 < 1f) {
num3 = Mathf.Pow (num3, this.recipe.roomSurgerySuccessChanceFactorExponent);
}
num *= num3;
}
num *= this.GetAverageMedicalPotency (ingredients);
num *= this.recipe.surgerySuccessChanceFactor;
if (Rand.Value > num) {
if (Rand.Value < this.recipe.deathOnFailedSurgeryChance) {
int num4 = 0;
while (!patient.Dead) {
HealthUtility.GiveInjuriesOperationFailureCatastrophic (patient);
num4++;
if (num4 > 300) {
Log.Error ("Could not kill patient.");
break;
}
}
}
else if (Rand.Value < 0.5f) {
Messages.Message ("MessageMedicalOperationFailureCatastrophic".Translate (new object[] {
surgeon.LabelShort,
patient.LabelShort
}), patient, MessageSound.SeriousAlert);
HealthUtility.GiveInjuriesOperationFailureCatastrophic (patient);
}
else {
Messages.Message ("MessageMedicalOperationFailureMinor".Translate (new object[] {
surgeon.LabelShort,
patient.LabelShort
}), patient, MessageSound.Negative);
HealthUtility.GiveInjuriesOperationFailureMinor (patient);
}
if (!patient.Dead) {
this.TryGainBotchedSurgeryThought (patient, surgeon);
}
return true;
}
return false;
}

private float GetAverageMedicalPotency (List<Thing> ingredients)
{
if (ingredients.NullOrEmpty<Thing> ()) {
return 1f;
}
int num = 0;
float num2 = 0f;
for (int i = 0; i < ingredients.Count; i++) {
Medicine medicine = ingredients [i] as Medicine;
if (medicine != null) {
num += medicine.stackCount;
num2 += medicine.GetStatValue (StatDefOf.MedicalPotency, true) * (float)medicine.stackCount;
}
}
if (num == 0) {
return 1f;
}
return num2 / (float)num;
}

private void TryGainBotchedSurgeryThought (Pawn patient, Pawn surgeon)
{
if (!patient.RaceProps.Humanlike) {
return;
}
patient.needs.mood.thoughts.memories.TryGainMemoryThought (ThoughtDefOf.BotchedMySurgery, surgeon);
}
}
}


and i suspect that is where the magic happened :p

But i'm still trying to understand what that means as i just learned how to access it yesterday ;-)
