Since Yandere Simulator is made in Unity, it can be modded. There are various types of modding:

Students.json Modding

By modding the game's Students.json file, you can edit the game's students in a variety of ways.

You can see all info here: Modding/JSON Files.

Topics.json Modding

By modding the game's Topics.JSON file, you can edit the students' opinions on different conversational topics.

You can see all info here: Modding: Topics.json.

Cutscene Commands Modding (Pose mod)

Cutscene commands give a whole new world of modding. With them, you can change student textures without replacing any textures, give otherwise unusable hairstyles to students, and much more.

You can see all of the information here: Modding/Cutscene Commands.

DLL\Source code Modding

By modding the game's Assembly-UnityScript.dll or Assembly-CSharp.dll file, you can do all sorts of things, like edit the students' additional info, make new hair and eye colours for students and etc.

You can see all the information here: Modding/Assembly-UnityScript.dll.

Pikachuk Modding Engine

PME engine allows mods to replace the entire school, entire characters models and more, you can get more informations here: Modding/Pikachuk Modding Enging.

  7. Go to "Export/Selected Assets". Select a folder.
  8. Go to that folder and to its generated subfolder (It will be called Texture2D).
  9. Open UABE
  10. Go to File/Open. Select your .asset file from 'YandereSimulator_Data' folder. (If you used Unity Studio, open the one from step 6!)
  11. Go to View/Search by name
  12. Find the texture you need.
  13. Check the type and make sure it's 'Texture2D'.
  14. Click on it once to select it.

  2. Name the file something like 'EDITsharedassets8.assets', NOT

'sharedassets8.assets' or it WILL NOT WORK.

  1. Go to the 'YandereSimulator_Data' folder and move the original
  2. asset somewhere else. Rename your file to something like

'sharedassets8.assets' but with your asset number.

  1. Test the game to make sure it worked!

Audio Modding

You will need

  • .wav files of the music you want to add. You can ONLY use .wav , otherwise it WILL NOT WORK.
  • Unity 5.6.5 (DL Link)
  • Unity Asset Bundle Extractor (DL Link)

For a video tutorial, use this video. It's for 7 Days to Die,but it can also be used with Yandere Simulator.

Tutorial

  1. First, rename your .wav files so that they're the same as the files you're replacing (For example, if you're changing the Main Menu music, rename it to MainMenuCute.wav).
  2. Launch Unity and create a new project. Name it whatever you want.
  3. Delete the directional light and main camera.
  4. Drag your .wav files into the assets folder on the bottom half of the screen, and then drag them into the scene.
  5. Go to File > Build Settings, select "Development Build", and click "Build." Name the file whatever you like. Wait for it to build.
  6. Open the folder you just created. There should be a subfolder titled "yourfilename_Data." There will be two files: sharedassets0.assets and sharedassets0.resource. You will need these later to make a dump file for the music.
  7. Open Unity Asset Bundle Extractor, and open sharedassets0.assets using the program.
  8. Once it's loaded, you should see your music files as AudioClips. Click on the AudioClip files and select "Export Dump" on the right side of the screen. Export them to whatever folder you like
  9. Open the folder where you just exported the dump files and rename them the same name as your .wav file. (Ex. MainMenuCute.txt)
  10. Go back to yourfilename_Data. Rename sharedassets0.resource whatever you'd like (I typically keep it the same name as the .wav file, such as MainMenuCute.resource).
  11. Open each dump file in notepad. Where it says "sharedassets0.resource", change it to whatever you just renamed it as. Save each file.
  12. Copy your .resource file and paste it into YandereSimulator_Data.
  13. Open Unity Asset Bundle Extractor again. Open the sharedassets.assets folder that contains the sound you want to change. Find the AudioClip, then select "Import Dump" on the right side of the screen and select the dump file you want to use.
  14. Go to File > Save, and save the sharedassets.assets file to YandereSimulator_Data. Name it something like EDITsharedassets8.assets but with your asset number. Do NOT name it sharedassets8.assets, or else it will not work.
  15. Go to YandereSimulator_Data and move the original sharedassets.assets file somewhere else. Rename your edited file to something like "sharedassets8.assets", but with your asset number.
  16. Run the game. Your custom sound should play!

Texture Modding

This kind of modding is used by those who want to make custom hair colors, uniforms or such. In order to mod the game's assets using this method, you will need the Unity Asset Editor program.

  1. Open Unity Asset Editor. (If you do not have UAE yet, the download link is here.)
  2. Select the sharedassets files of the Data folder desired.(Look to list of sharedassets for the desired texture location).
  3. Choose the file you want and export it. If it is a texture that you want to edit, this is what the file MUST look like when you export it. To export, Right-Click the name of the texture file and hit 'Export':
    Example

    Look for files with the type "Texture" as shown

    If you do NOT see any files that are type 'Texture', reopen UAE and the sharedassets file and try again.
  4. Edit the texture(s) as you want (You need an image editing program that has DDS support. Paint.NET supports DDS, but be sure to set Mipmapping to auto while saving your image or it will not upload correctly.)
    What you need to set when saving a DDS file on Paint

    This needs to be checked when saving a DDS file for a Texture on Paint.NET.

  5. After editing them, save them and import them in the UAE to replace the old texture. Make sure that you saved the texture to the same name as the old texture before uploading.
  6. Save all the changes and play the game.The textures you edited will appear in-game.
  7. IF YOUR TEXTURE DOES NOT UPLOAD PROPERLY AFTER BEING EDITED MAKE SURE THAT IT IS BOTH MIPMAPPED FROM THE EDITING PROGRAM /AND/ THAT THE OPTIONS CHOSEN FOR THE TEXTURE MATCH THE REQUIRED PROGRAMMING FOR THE GAME. Most opaque textures use a format called "DXT1" while most transparent and translucent textures use a format called "DXT5." You can change the format while saving your edit. Make sure it matches up to the format that the game requires.
    PAY CLOSE ATTENTION

WARNING: If UAE keeps crashing when you try to load a texture, do this: Go into the Texture Plugins folder in the UAE files, and then go into the NODX file, it'll contain Texture.dll. Copy the file and go into the Plugins folder. Enter the Default folder and paste it.

Tutorial (Separate Program)

  1. Assets file button

    The 'Open Assets-file' button in Unity Assets Explorer

    Open Unity Asset Explorer (download it here.)
  2. Click the 'Open Assets-file' button
  3. Open the .assets file that contains the textures you want to edit.

    Folder

    The sharedassets folder.

  5. Right click on the file you want to edit.
  6. Select 'Extract This File'.
  7. Find the place where it exported your files. (Trust me. I had to find mine.)
  8. Edit the texture(s) as you want (You need an image editing program that has DDS support. Paint.NET supports DDS, but be sure to set Mipmapping to auto while saving your image or it will not upload correctly.)
  9. Shared assets 8

    Me importing a DDS file in sharedassets8.assets

    Save the file in the folder where the original was exported, making sure the name is the same. Replace the old one.

Meshes (3D models) Editing

*Note: The reference for this tutorial was by Pikachuk on YouTube (specifically this video), but it's in French. I did my best to translate it; edits from more experienced modelers and modders are welcome!*

Hello! I'm Flower-kun. I saw that a lot of people were requesting something like this, so I decided to provide!

THIS DOES NOT WORK WITH .pmx FILES, ONLY .pmd FILES!!!!!

...or .obj files, y'know.

You will need:

Alright! Let's get started!

Hairinport-0

the hair I'm using

For this tutorial, I'm going to replace the Miku hair with this custom model (It is indeed an MMD hair model!) So let's get started!

Tutorial

  1. Open the character model skeleton in 3DS Max.
  2. Run the PMD import script by selecting 'Run Script' in the Scripts menu (in the top bar).
    3dsmax1

    deleting the base model

  3. Import your hair, making sure to uncheck every box except for 'Model' and 'Physics'.
  4. Resize and move your hair until it's on the model the way you want.
  5. Exportt

    exporting the model as a .obj

    Delete the character skeleton and save the hair as a .obj file.
  6. Open up Unity and create a new project.
  7. Importasset

    importing your model

    Select the 'Assets' button at the top and choose 'Import New Asset'.
  8. Choose your .obj that you just made. It should show up as an asset.
    Buildassets

    the buttons are highlighted

  9. Drag the bottom picture of the model to the grid to import it to a scene.
  10. Go into file and select 'Build Settings'.
  11. Select 'Add Current' and save your scene.
  12. Click 'Build'.
  13. Wait for it to build.
  14. Go to where you saved your game. You should see a YourBuildName_assets folder that contains sharedassets0.assets.
  15. Open up sharedassets0.assets with Unity Assets Bundle Extractor.
  16. Find your mesh (Mine was named default, because I forgot to name the model - oops!).
  17. Right click and select 'Export'. Save the .data file.
  18. Open up the sharedassets in Yandere Simulator that contains the hair you want to replace (mine is in sharedassets9).
  19. Press Export Raw. Export to wherever you want and give any name. Then press Import Raw, select your mesh, and press OK.
  20. Find the texture of the mesh you replaced (there's a search function).
  21. Press Plugins/Edit/Load and select your texture, then press OK.
  22. Follow the texture replacing tutorial above.
  23. Go to File/Save, add the extension ".assets" and rename the file to something like "EDITsharedassets8.assets". You MUST save the file as something else; the game will not work right if you don't.
  24. Go to your "YandereSimulator_Data" folder where your modded file is located. Move the original .assets file so you have a backup in case something goes wrong. Rename your modded .assets file to the original file's name.
  25. Open up the game and scroll through Yan-chan's hairstyles - you should find your hair! (My game crashed because I have a bad computer, so sorry there's no pictures...)
  26. Alternatively, you could use the Pose Mod to put you models in the game like the fake Kizana hair - a tutorial for this is coming soon, probably on the Pose Mod commands page.

You can use this to replace virtually any object, I was just showing how to replace a hair model. Anyways, have fun modding! ~Danny

Yandere Mod Loader

Warning: It's bad english because it's written by a french. Fix me if you see mistake.

Yandere Mod Loader is a beta tool for loading mod into Yandere Simulator. It allows the possibility to load multiple at once. Firstly, you need to know programming in .NET language like C# or VB.NET.

Download:

Creating the base of the mod

Open your IDE and create new project "Library". Its name will be the ID of the mod. Create a class named "[ID]_installer" (Example: GuyMod_installer).

In the class add a static method "Install". Extract Yandere Simulator and Yandere Loader into the generation folder of your project (by default: "%UserProfile%\source\repos\projectName\bin\Debug\").

Add in project references all of dll of YandereSimulator_Data\Managed (except mscorlib.dll and all library which starts by System).

Back on Visual Studio, in Install() method, you'll put instructions for install mod.

Example:

new GameObject("GuyMod").AddComponent<GuyMod_installer>();

DontDestroyOnLoad();

If you write this code, the compiler throws an error. You need to add " : MonoBehaviour" just after the "class GuyMod_installer".

The base of the mod is almost finished. Create new JSON file named modpkg.json. Put:

{

"id":"GuyMod",

"name":"Guy Mod",

"version":"1.0"

}

In properties, set Copy to output directory to true or Always Copy (depending the version).

In project properties, set the Generation folder to /bin/Debug/mods/GuyMod

Generate and the mod will appears on the list in-game !

For add code in each update and in start of game, simply check the methods of MonoBehaviour (Unity)

Change student routine

You need the base of your mod.

Create update method:

void Update() {

}

Into the function, add a foreach iterator and a if statement for selecting the student. Example:

The student is Budo Masuta. His student id is #21. I want to move his position at 3 PM. (15 hours in 24h format (+ 12))

void Update() {

foreach (var student in FindObjectsOfType<StudentScript>()) {

if ((student.ID == 21) && (FindObjectOfType<ClockScript>().HourTime == 15f)) {

student.CurrentDestination.position = new Vector3(0, 0, 0);

student.CurrentDestination.rotation = new Quaternion(0, 0, 0, 0);

}

}

}

TIP: For getting position and rotation, you can use the pose mod and enable the label in advanced options.
