    Charlotte's Utilities

    Charlotte's Utilities mod for Minecraft Forge made by Sharshar

    Charlotte's Utilities is my first adventure into modding Minecraft. I wanted to have some extra utilities and things for my server that I couldn't find in other mods, or if I could I was able to think of a different way that I would prefer to implement them. At its core, this mod pack is just a collection of utilities that I feel improve the game experience. Everything is fully configurable in the config file so you can change, enable, or disable whatever you feel is best for you! The mod has quickly developed into one that's aimed primarily at the builders of the Minecraft community, and I plan to expand on that idea going into the future. My goal is to provide new, unique, and easy ways to allow players to construct whatever comes to their mind. I take feedback very seriously and if you have a good idea I won't hesitate to implement it. Development of Charlotte's Utilities is made possible by Full Effect Hosting

    MCBullsEye

    Bow and Arrow BullsEye game plugin for Minecraft Bukkit servers

    MCBullsEye is a Minecraft game plugin allowing you to create Bow and Arrow courses for competitions. Each player plays on their own course. Multiple games with multiple courses can be created. Create multi-player courses and compete head-to-head to blow-up your targets first. Use any block as a target. When the block is hit it explodes. This is the first beta. I believe most functionality is working properly, but I've only tested it on my machine. Any feedback is appreciated. Known issues: Directional blocks may not stay facing the direction they were placed after the game is reset. Future functionality: Disappearing target blocks.
