The former array has been busy with a mess of things, school holidays seven days, sleep a day to see the movie day, there are some trivia, although the Development Board to take back, but also only to increase the fetters of the trip, said the course will be in the holiday period to write the system, finally only half of the writing. This led to the tragedy behind the great chaos.Can not wait to return to the music embedded, feel or learn something mo
to hurt, attacking to hurt. This can is useful, but can also get complicated really fast. If your AI requirements ARE fairly simple, that's a lot of potentially unnecessary overhead. Another difficulty with transition-based the state machines are that it's difficult to debug. If you set a break point and look at what the AI's is, it's impossible without additional debug code to Kno W How the AI got into it current state, what is the previous states were and what transition is used to get to the

A series of articles starting from this article will cover a complete high-performance server model, but for the server cluster architecture, it's not the scope of this series, it's going to be what I'm going to do in the next few weeks. A friend told me that I would like to provide a complete code for the underlying

Personally feel that the time to write code is too little, to their own level of improvement is very limited. As for the server piece, always deploy PHP environment,
