Minecraft for Windows mod manager

Minecraft for Windows mod manager (Bedrock Edition)

Features

• Simple, clean user interface
• Manage and launch internal and external mods, both stored locally and from the Internet
• A version manager that goes hand in hand with the mod manager
• Switch between different game data folders with Profiles (resource packs, worlds, settings, etc.)
• Extreme customizability, from the launcher's appearance down to the source code
• Easily apply Renderdragon shaders and make your game look beautiful

Installation

If you're a regular user, you can download the installer here. It's about 6 MB in size.

Older releases can be found in the Releases page.

You can clone the repository and build Jiayi Launcher yourself with the instructions below.

Building

Requirements

• A computer running Windows 10 or later
• Git
• .NET 8 SDK
• Optionally, an IDE that supports .NET 8 (e.g. Visual Studio 2022 or JetBrains Rider)

Steps

1. Clone the repository

• git clone --recursive https://github.com/JiayiSoftware/JiayiLauncher.git

With an IDE:

2. Open the solution file in the IDE
3. Build the solution

Without an IDE:

2. Navigate to the repository's root directory
3. Run dotnet build

This will build the launcher in debug mode. You can append -c Release to build in release mode.

Contributing

If you want to contribute to Jiayi Launcher, you can fork the repository and submit a pull request.

Jiayi is written in C# and uses HTML for the UI via Blazor Hybrid.

The code is admittedly a mess, hence why there is no code style to adhere to. However, please try to keep the code clean and readable. There will be a code style guide in the future.

License

Jiayi Launcher is released under the GNU GPL-3.0 license, and you can read it here.

A quick rundown for those who don't want to read all that:

• You can modify, share and sell the code any way you please
• but you have to open source projects that do this under a compatible GPL license
• Any changes should be documented

jiayilauncher's Issues

Timeout while downloading from jiyayi.mcpeplayground.com. Also Profram doesn't do anything.

Prety Obvius Fixes:

1. Use Github Actions ( free for public repos ).
2. Use a normal DDL site like Mediafire.

Launcher crash when downloading version (so far 1.18.31, which had no error but straight up just closed the launcher, 1.19.71 and 1.19.73 are the ones that don't seem to work, though I havent tried anything else.)

Proposal: Consider using Appx Packages

This would have many advantages:

• Easy installation
• Easy to uninstall
• Follows the overall standard of a Windows application
• Allows to reset app data from settings (and cache, ...)
• File extension can be specified in package manifest
• Easy for other apps to find the program on your system

Edit:

• You can (or need to) sign the appx package, this would allow people verify that the package is legit
• (Microsoft Store!?)

very deep crash when trying to switch versions

i think it's an issue with winrt because of how deep this stack trace is but i could be wrong

Error code 0x80040403 thrown when trying to get update tokens
