    Minestom

    Minestom

    1.21.11 Lightweight Minecraft server

    Minestom is an open-source Minecraft server development framework that allows developers to build custom Minecraft server software from scratch without relying on Mojang’s original server code. Instead of functioning as a traditional server implementation, Minestom acts as a lightweight library that provides the core networking and gameplay infrastructure needed to create Minecraft server applications. Developers can use it to design custom game modes, experimental server architectures, or entirely new gameplay systems while maintaining compatibility with the Minecraft Java Edition client. The framework focuses on performance, modularity, and extensibility, allowing developers to include only the features required for their specific server projects. Because Minestom is designed with a minimal base architecture, it enables high performance and easier scalability for custom server environments.

    Stone Lantern V1.0 (MC 1.5.1/1.5.2)
    Mod Name: Stone Lantern Default ID: 184 Version: 1.0 MC Ver's: 1.2.5, 1.3.1, 1.3.2, 1.4.2, 1.4.4, 1.4.5, 1.4.6/1.4.7, 1.5.0, 1.5.1/1.5.2 LU: [13.04.04] This mod adds a craftable Stone Lantern to Minecraft. I made this mod so you can easily craft as many Lanterns as you need. Why this is needed in Minecraft: - Jack-O-Lanterns: I got sick of having to find Pumpkins. Then having to plant, wait for them to grow and harvest them. You can't even place Jack-O-Lanterns without a block under them first. Who wants to look at that all of the time anyway? - Redstone Lanterns: You literally have to go to Hell (The Nether) and back to craft them. And they have to be powered by a Redstone Torch or a Switch. Too much of a pain to craft, and not Renewable. I hope Mojang adds this to Minecraft in a future update. PS: Source Code is also included in the zip files. :-)
