McModsync

A graphical Powershell tool to synchronize Minecraft mods from server to local.

McModsync is a simple Powershell script for Microsoft Windows, that helps maintaining Minecraft mods at client side. It provides a Windows Forms based GUI for better usability.

Usage

This tool assumes there is a web server somewhere, providing all mods in a certain structure. More on server side setup in server setup.

Client side usage

In the following paragraphs, all parameters of McModsync are explained.

Directory

This is the target directory, where mods will be installed. Actually it is the base directory, where the Minecraft game files are installed. The MinecraftLauncher.exe is located in there.

Either write the path into the lower box manually and press Select button, or choose the volume from dropdown and search for the installation directory automatically.

URL / Modpack

This is where the server base URL needs to be entered into the upper box. Upon pressing Fetch, McModsync will try to fetch a list of available modpacks from the server, which can then be chosen from the dropdown.

Components

This is where the components to synchronize are selected.

Actions

In this table, all mods requiring an action are listed. These actions can be one of ADD, UPDATE, DELETE.

Check and Sync

By pressing the Check button after fetching modpacks, McModsync compares the local mod list with the remote one, and determines which actions are required for each mod. When pressing Sync button - after Check - it will download all selected components if necessary and take listed actions for mods.

Attention

McModsync will create a folder tmp inside the Minecraft installation directory, where all files are downloaded to. If selected, the forge installer is located inside this folder too after Sync.

Resourcepacks and shaderpacks are not related to a certain modset, hence they are overridden every time on Sync, unless they are not selected in the GUI.

Minecraft mods are located in a folder mods. When syncing a modset with McModsync a file .listing is placed in there. Do not modify this file! It is used to keep state of installed mods. When syncing a different modpack, all mods in this folder are removed permanently. You need to take backups on your own.

Add client side mods

Mods that are just placed into the mods folder are not affected by the synchronization process, as only the ones listed in .listing are maintained.

Server setup

As server any web server (nginx, apache, ...) can be used. The following directory structure is required to be accessible by any client.

/.info
/resourcepacks.zip
/shaderpacks.zip
/<major version>
    /<minor version>
        /<bugfix version>
            /<modpack>
                /.listing
                /forge-installer.exe
                /<mod (.jar) files ...>

Example:

/.info
/resourcepacks.zip
/shaderpacks.zip
/1
    /12
        /2
            /all
                /.listing
                /forge-installer.exe
                /mod.jar
