    Fusion library

    Fusion library

    Futuristic Luau for every universe

    Fusion is a lightweight companion library for the Luau programming language designed to simplify application development, particularly for projects built on the Roblox platform. The framework provides tools for organizing program logic into reactive chains of data and state changes, allowing developers to build complex systems using clear and predictable code patterns. Fusion emphasizes a reactive programming style where user interface elements and other components automatically update when underlying state values change. This approach helps developers manage dynamic behaviors without manually updating every dependent variable or interface element. The library is portable and can be used outside of Roblox environments as well, although it includes built-in configurations that integrate smoothly with Roblox development workflows. Fusion aims to reduce boilerplate code and improve readability by encouraging declarative programming patterns.

    vim-be-good

    vim-be-good

    nvim plugin designed to make you better at Vim Movements

    vim-be-good is a fun, game-oriented Neovim plugin developed by ThePrimeagen that turns learning and practicing Vim movement commands into an interactive experience. Rather than merely memorizing keystrokes, users play engaging mini-games inside Neovim where they must use proper movement commands (like jumping, searching, and editing) to complete challenges, making skill development more enjoyable and practice less repetitive. The plugin is designed specifically for Neovim and includes multiple game modes that focus on different aspects of Vim core mechanics, so players can build muscle memory for navigation and text manipulation commands as they play. It intentionally blends learning with play, which appeals to both newcomers who want to level up their proficiency and experienced users who enjoy sharpening their skills. The project often incorporates humorous and creative design elements, reflecting its development during live streams and community interactions.

    PropHunt

    PropHunt

    PropHunt plays much like a Hide and Seek.

    ***ATTENTION!!!*** Searching the lastest version? https://steamcommunity.com/sharedfiles/filedetails/?id=135509255 ****************************** PropHunt plays much like a Hide and Seek. Players on the RED team, disguised as props, are given a 30 second set up time to hide, and afterwards players on the BLU team attempt to find and kill them in the allotted time period. At the end of each round the teams are swapped; the Hunters (BLU) become the Hunted (RED) and vice versa. Respawns are not permitted until the end of each round. Originally made for TF2. CREDITS: Credit goes for the original authors of both gamemodes and who made Prop Hunt compatible with GMOD 13. Originally written and released by Darkimmortal (TF2) If you are the autor or if you have credit, and you won't see the mod on the workshop anymore don't hesitate to contact me. I just published to Workshop and fixed something.
