DEPRECATED!

A funny game for a good company similar to karaoke
Apozh is a game similar to karaoke for 2 or more players. One player sings a song while the second player should not hear it,
then the song is turned backwards, and the second player tries to sing it in the 'reversed' state.
Once the second player finished singing, his recording is also turned backwards.
Then the second player tries to guess, what was the first player's song.
A sound card, microphone and speakers are required to play this game.
An alternative/custom Minecraft server, written in Java, compatible with the original protocol. OpenCraft is built upon Apache MINA, SLF4J, Jython and XStream. The aim is to have features not in the official server distribution, like antigrief/scripting.
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 :)
