    webmc

    webmc

    PoC Minecraft client written in Javascript

    WebMC is an experimental proof-of-concept Minecraft client written in JavaScript that runs directly inside a web browser. Instead of requiring a traditional desktop installation of the game, WebMC allows users to connect to Minecraft servers from a browser environment. The client communicates with a WebSocket proxy that bridges the browser connection with the standard Minecraft server protocol. By leveraging browser technologies and modern JavaScript libraries, the project demonstrates how a voxel-based game client can run using web-based graphics and networking systems. WebMC also showcases how browser-based applications can interact with multiplayer game servers using real-time communication channels. The project is primarily intended as a technical experiment and educational demonstration of browser-based game development.

    MCiSEE

    MCiSEE

    All of Minecraft, EASILY get Minecraft resources

    MCiSEE is an open-source project designed to integrate Minecraft with computer vision and artificial intelligence experiments. The system focuses on capturing visual information from the game environment and exposing it to external programs for analysis or machine learning research. By converting gameplay data into visual or structured formats, MCiSEE enables researchers and developers to build AI agents capable of interacting with the Minecraft environment. The project can be used as a research platform for tasks such as reinforcement learning, perception analysis, or automated gameplay strategies. It bridges the gap between game simulation and AI experimentation by providing tools that connect Minecraft gameplay with external algorithms. Developers can extend the platform to test new approaches to artificial intelligence within a complex virtual environment.

    MineMonitorCraft
    You all know this: Mojang released the new version of Minecraft and the game wants to be updated now. But all the mods what you added to the game is not working because the are not released yet for the new version. Now is the time to check every hour/day/week for changes at wiki's Mods page. I was annoyed to do that and wrote a windows sidebar gadget, which will do that for me. Yes, i know, the time for gadgets is running out. If i see some interest, i will create this as stand-alone application.
