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 :)

The Bronze to Masters Evaluator (B2Meval) evaluates Starcraft 2 games with respect to multiple macro aspects. These are worker and supply count at specific times, expansion timings, building timings, as well as research and upgrade timings. The B2Meval is a SC2gears plugin. Hence, SC2gears is required. The B2Meval shows specific values of unit counts and timings that are recommended by filtersc's macro tutorials. Please, refer to filtersc's macro tutorials on teaamliquid.net or YouTube.com for more information about these values.

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!

Deep Matrix is a Java chat-client and server system that turns 3D VRML/X3D worlds in to multi-user enviroments. The current version "Deep MatrixIP9" works on Windows, Mac, and Linux OS systems.

The system is divided into two parts: the client and the server. Clients at different geographic locations in the network connect to a single server by specifying its IPv4 address. The user gets into the system using his/her username and password. Each user has to make an account for himself in the beginning. His account information will be stored on the server machine in persistent form. Server sessions will have no effect on its accounts. The server can be running anywhere on the network. The players play in a virtual environment among walls and obstacles (walls are porous, beware!). The shots fired at an opponent within range will cause him to lose 'life' points. The target is to kill maximum number of opponents. Once a player is killed he is logged out and then may reenter. At the end a scorecard showing the number of logins and the number of kills of all players of the current session is displayed at each terminal. I have used fairly basic models, animations and a simple map.

The following optimization objectives are being regarded: - Each player should be scheduled for each table position equally often. - All combinations of team-mates should happen equally often. - All combinations of opponent players should happen equally often. - The leisure times of each players between its participated matches should be distributed as equally as possible.
