In Yandere-Simulator you can mod the game to create custom content and other cool things that would not usually be in the game. This page will give you tips, tricks and help from a JSON Modder (Ty-dere) if you wanted to create your own mod that includes editing JSON Files..

This page is allowed to be edited as long as your information is correct.

If somebody has asked a question and it has been answered, put it in the FAQ section.

Compatibility

When YandereDev releases a new build for Yandere Simulator, make sure you test your mod before saying it is compatible!

Before You Start...

Before even starting to create your mod, BACKUP YOUR FILES, and put the original somewhere safe where you can easily put it back into the game and won't forget where it is. Your desktop is a good choice. Here is the layout of my backup JSON files. (If making more than 1 backup, make sure you put the JSON in seperate files.)

Ty-dere's Mod Backups

This image shows Ty-dere's backup files for Yandere Simulator. These backups are from the September 29th Build.


  • Tip: Rename your folders after mods you are using. I have not done this in the picture as the "Used Backup" is a mod I have not released.

Handy Links when Modding:

The JSON editor I use is online and it is called JSON Editor. You can use Notepad or Notepad ++ If you have these.

(The wiki is not affiliated with this website or any programs mentioned. It is third party and we don't have control over it. Use at your own risk!)

Getting Started

#1 Modding Rule: Use your backups, NOT your Students.JSON in the YandereSimulator's StreamingAssets folder.

Right, without further ado, lets begin!

First go to a JSON site or Notepad (or Notepad ++) and begin. I am using JSON Editor Online (as mentioned earlier.)


  • Tip from Ty-dere: Use the right hand side! It has a cleaner interface for you to work with!

This is what the editor will look like after importing Yandere Simulator files:

Editing Key Info

I had to trial and error creating mods as I had no guidance whatsoever, but I will make your life easier and give you all the key information.

Name:

Note 1 - also works for the "Unknown" and "Reserved" students.

Note 2 - removing the quotation marks around the name will cause KoharuHair to spawn.

Note 3 - changing the student's name to "Unknown" or "Reserved" will cause the said student to stop spawning.

Displayed on student info screen and other screens that display the student's name. Anything that is typed will become the student's name.

Sometimes certain names will make the whole school appear as flaming ghost students, such as the name "Shimiro Shita" will do this.

Gender:

Note 1 - male and female models have a different set of animations (Example: male students don't have an animation for texting , so they will instead start glitching out if the required animation doesn't exist).

Note 2 - certain students will glitch out if their gender is changed.

Customuntexturedsocks
As March 8, the player is able to add custom stockings to a female by creating a texture inside of the streaming assets folder. The name of the texture must be "Custom.png".

If the player doesn't create a custom texture or uses an invalid name, the stockings will be thigh-high and colored grey.

Eyes

Note - As 28th march build. the player has the ability to change students' eye color by their preference.                     If you use the ID "Waifu" it will give the student grey eyes. Same happens with student-specific eye colours.

Special Hairstyle Colors:

Note - special hairstyle colors might have additional effects (Example - using Ganguro color on hairstyle 19 gives the student tanned skin and makeup).

These colors only work with their own corresponding hairstyles. They can not be applied to any other haircut. Using a basic color on hairstyles with a special base color will result in unique color combinations.

As the most recent builds, special colors are equivalent with the "None" hair color.

Daily Schedule Animations

You can make a student follow a daily schedule by using the following animations.

Note - giving a male student a female student only animation will only make the edited student will spin in place.

Image ID Description Gender
Mourning Yui Rio
Mourn An animation used when a dead loved one passes away. This animation is triggered when you kill one of the Basu sisters, but not the other.

This animation is also triggered if a female student is turned into a mindslave.

Even if a student hasn't had a loved one pass away, you can still make them mourn as part of their daily schedule.

Schedule Destinations

These are the locations you can place students in their schedule. I have not added Seat as there is a section explaining that.

Image Id Description
Spawn This is where a student spawns each day. It's different for every student, so to know where they will stand I would suggest checking where they spawn first.
Exit This location will make a student leave the school.

If you go to class the student will spawn at their seat.

Locker This location makes a student go to their locker. like Spawn, each one is different so check the ID's locker first.
Club This destination will make the student go to their respective clubs.

This only works for the Rainbow Six, the Occult Club (the six meant to be in the club), and the Martial Arts Club (again, those meant to be in the club). If you give them a different club, they will still go to their intended spot.

If one of the Rainbow Six does not have a club, she will go to her spot that she hangs out.

MournDes
Mourn This location will make the student go where the Basu sisters mourn.
SlaveDes
Slave This location will make the student go to where

a mind broken slave would.

Stalk(Female) This will make a student go to where Oka stalks the Basu sisters in the morning.
MaleStalk
Stalk(Male) This will make a student go to where Riku stalks Kokona.
Podium This will make a student go to their classes' podium.
Patrol This makes a student walk around the first, second, or third floor depending on their ID.

If Patrol is not in the animation slot, then students will stay near the occult club corridor.

Hangout This destination depends on the student's ID. It will only work for the rainbow twelve, Basu sisters, Kuu Dere, Mai Waifu, Pippi, Ryuto, Midori, and Senpai.
Cuddle (Male) The student will go where Riku sits with Kokona after getting together.
Cuddle (female) The student will go where Kokona sits with Riku after getting together.
LunchSpot This destination depends on students ID. Students will go where that student spends their lunchtime.

These are all I am currently aware of, so feel free to add more if you find any!

Since The June 15 update, you cannot put hangout and lunchspot on a unknown students

edited students only!

FAQ

Anything not answered? Comment down below and someone will help you as soon as possible!

Q: I have modded my game, but all students are girls and they are on fire and have Osana's hairstyle! What do I do?

A: You've probably made a mistake while editing the JSON file. To fix this problem you need to delete the faulty Students.JSON file and replace it with a backup you made.

Q: I didn't make a backup! What do I do now?

A: Download the November 19th 2016 Build Students.JSON File here! Make sure to make a backup of the Students.JSON file next time!

Q: How do you edit students' additional info?

A: Visit the Modding: Assembly-UnityScript.dll page. Everything you need to know about editing the additional info can be found there.

Q: How do you give students more hair and eye colours?

A: There are two ways: The first one is to edit the hairstyle's base texture (Visit the Modding page for more info), while the second one is to edit the game's Assembly-UnityScript.dll file (Visit the Modding: Assembly-UnityScript.dll page for more info).

Q: How do you edit the students' facial features/uniforms?

A: You cannot edit individual uniforms of students except for Oka, Musume, Kokona, Saki, Mei, Koharu, Yuna, Yui, Midori and Osana. You can edit facial features of any student by editing the base hair of the student in the Texture files via assets, but there is no other way except for what is listed on the Modding page.

Q: Fun Girl showed up when I launched the game! What went wrong?

A: You most likely made a punctuation error in the .JSON file while you were editing. The more common errors include deleting a quotation mark, deleting a comma, and/or a punctuation mark changing font. To fix this error, replace the incorrect punctation(s) with the correct ones by copy/pasting the correct punctuation instead of typing it out normally. You can check for incorrect punctuation by using CTRL F (Windows) or CMD F (Mac) and pasting the incorrect punctuation mark in the search bar.
