DDLC Plus Injector

Mod/DLL support for Doki Doki Literature Club Plus.

I'm working again on this project, obviously I have other things to do, so if you want to add something any PR is welcome.

NOTE: This might be pretty obvious but for developing/using mods you need to have a copy of the game, You can buy it on https://ddlc.plus.

Work in progress

This is just a work-in-progress, so don't expecto something too stable or a massive amount of mods.

Installing

1. Download a patched DDLC.dll from the Releases page
2. Put the patched DDLC.dll in the folder Doki Doki Literature Club Plus_Data/Managed/ of the game
3. Download the DDLC+ Injector.dll file from Releases or compile it by yourself cloning this repository and compiling the Injector solution
4. Put the downloaded file in the root of the folder of the game
5. In the root of the game folder create the mods/ folder
6. Install mods and put them into the mods/ folder

Please, before doing anything do a backup of the original DDLC.dll file, Because if something goes wrong you will have to reinstall the game.

Now the DDLC Plus folder should look like this :)

For Developers

This is just a little guide of how to develop mods for DDLC Plus in a easy way.

1. Create a C# solution (Specifically a DLL .NET Standard solution) using Visual Studio (You can use any IDE but I haven't tested with others)
2. In the project dependencies add the *.DLL's that are in the DDLC Plus folder (Doki Doki Literature Club Plus_Data/Managed)
3. Add your code
4. Compile the project
5. After compiling, Put the DLL file in a folder called mods/ in the DDLC Plus base folder
6. Test (Obviously for testing you have to install the Injector first)

In order to interact with the game, you should write the mod like a Unity game, with the MonoBehavieour GameObjects.

A little example of how write a simple mod:

using UnityEngine;

namespace DDLCPlus
{
    public class Mod
    {
        public static void Start()
        {
            Debug.Log("Hello, World!");
            Debug.Log("This message comes from an loaded mod!");
        }
    }
}

Now, if you run the game and you see the Unity's 'Player.log' file, You will see this:

Patching the game

This step is necessary when you want to patch the Assembly-CSharp.dll file by yourself. But you have to know that you will have to make many modifications to the file for making the mods work.

1. Install dnSpy
2. With dnSpy open the Assembly-CSharp.dll file (That is in Doki Doki Literature Club Plus_Data/Managed/Assembly-CSharp.dll)
3. Patch the 'Awake' method in the 'LauncherMain' class using the code in the Patch folder
4. Compile the patched file
