    CS:GO Multi Script

    CS:GO Multi Script

    Multi scripts for CS:GO that do just about everything

    I have not posted any of the code yet, I'm working on it locally then will push everything. This is not to be used in game (maybe deathmatch only :stuck_out_tongue:), but rather is meant to have some with the features that Java provides. I included all source so that you can see what I used. This is a great project to learn about global event listener, JRobot, JavaFX, etc... Most of the people said this just makes it harder to play the game, so it's not fantastic. The only thing I would say is worth getting banned over is the "camping" trigger bot and the crosshair overlay. The other features don't really provide an unfair advantage in my opinion. Either way, enjoy :)

    BukkitUI

    BukkitUI

    A Simple and Easy to Use User Interface for Private Bukkit Servers

    BukkitUI is a user interface replacement for the Bukkit console. It makes life as a server owner much easier, as it requires you to press a few buttons, until you have a running server! BukkitUI is written in Java, and is designed to be cross-platform, so Linux users (like me) have as much a chance at running a Bukkit server as Windoze users. BukkitUI has following
