Modding:Creating A Code Mod

This page was last verified for Vintage Story version 1.19.8.

Prerequisites

Before creating a code mod, you need to have completed the Preparing For Code Mods tutorial. This will show you how to setup your development environment, install dotnet, and install the modding template. If you have done that, you can carry on with this tutorial.

This tutorial is suitable for modders using Visual Studio. If you have chosen to use a different IDE, please refer to the older Setting up your Development Environment tutorial.

Updating the Templates

Before creating your mod, it is important to check for any updates to the Vintage Story template. Open Windows PowerShell or the command prompt, and enter the following command:

dotnet new update

This will check for updates for all templates, and install them if needed.

Recommended Knowledge

Before continuing, it is highly advisable to have some knowledge of Visual Studio and the C# programming language. These topics are out of the scope of this tutorial, however if you can understand the following tutorials, you should be okay:

• Starting with Visual Studio (YouTube)
• Create a .NET console application using Visual Studio (Microsoft.com)

Creating a New Mod

To create a new code mod, launch Visual Studio, and select 'Create a new project'. In the create menu, select Vintage Story from the dropdown furthest to the right. This will filter the list of templates, to only show ones with the "Vintage Story" project type.

Select the 'Vintage Story Basic Mod Template' and click next. This will load a new menu asking for a project name, location, and solution name.

Your project name should follow these requirements:

• Not contain any spaces or punctuation.
• Be formatted in PascalCase.
• Not be abbreviated (Use MyFirstMod instead of MFM).
• Be unique to any other mod on the VS Mod DB.

Your project name will also determine your Mod ID, however this can be altered later.

Your project can be created anywhere, and it is recommended to check the "Place solution and project in the same directory" checkbox.

When you have entered your details, click 'Create'. Your project will be created and Visual Studio will open.

Project Setup

Solution Explorer

When your project loads, you should see the Solution Explorer on the right-hand-side of Visual Studio. If not, you can open the Solution Explorer by clicking View and Solution Explorer from the top Visual Studio menu bar.

The Solution Explorer is a list of every file for your mod, and this is how you will create, open, and delete mod files. You can double left-click any file or folder to open it. Right clicking a file or folder will give you options to rename, delete, copy, and other file management tasks.

Note that any reference to 'MyFirstMod' will be replaced with whatever your project name is, and 'myfirstmod' will be your lowercase project name.

Mod Info

Double click on the modinfo.json file to open it, and you will see the following JSON code:

{
    "type": "code",
    "modid": "myfirstmod",
    "name": "MyFirstMod",
    "authors": [
        "Unknown"
    ],
    "description": "To be added",
    "version": "1.0.0",
    "dependencies": {
        "game": ""
    }
}
