Well I have made some changes, these are:
.- added an splash screen with the java, jpct, lwjgl, opengl and openal logo
.- redefined the changes publisher for notifing clients when a new player is on or off, etc.
.- Added the sound infrastructure
.- Added the chat infrastructure
.- fixed several bugs
.- improved some stupid things (I began the game hwhen I began programming, so there are many stupid code difficult to remove)
.- fixed problems when coloring special parts for diferent players
.- fixed the problem that sometimes the client cant began plating and some clients coulnt see others
.- some other things
I am still working from time to time but there still a lot of work before having a first release of my game.
