2. add the section in the file -INF\MANIFEST.MF

Class-Path: ./configuration/com.webex.crescent/ ./log

the work is built and the logger and property class for dynamic configuration have been creat,they are the basic class in the application development.

here is the tree;

the UI have not been modified much ,here is the little modified section

2007.11.23  timestamp(时间戳)

1.The definition "timestamp" is used in the row in a table in the database, it can help us  confirm whether the data in row has been modified . (在数据库中，确定"行"的数据是否发生变化)

 2. 在通讯程序中，网络接收到请求之后，我们会将请求缓冲到一个请求队列当中，当请求进列的时候打上一个时间戳，出列的时候进行一下时间比较，看其是否已经超时，决定是否对其进行处理。

3.The definition in MSDN:

  An   imprint   of   time/date   created   when   a   specific   event   or   process   takes   place. 

here we'll employ the  parameter "timestamp"  in the Interface "IRobot" ,methods (e.g. get* and set*) require a timestamp as a parameter.This is to help reduce the amount of I/O to the physical robot.If the timestamp is less than or equal to the value sent on the last call to one of these methods, old data is returned. If the timestamp is -1 or greater than the last timestamp, the robot is queried, and new data is returned.  The idea is that during each control cycle the higher level software will increment the timestamp and use it for all calls to these methods.

e.g.

2007.11.23 octant(八分仪),quadrant(四分仪),

From the ocean navigation, we learn some instruments,.e.g.,octant(八分仪),quadrant(四分仪),sextant(六分仪),in a standard Cartesian coordinates system (笛卡尔坐标系系统),we divide the 2D plane to 8 parts in octant,and other continue CCW.

For simulating the octant in ocean navigation(see the pic 1 ), we define the method Vector2D.octant() according to it,the method can analyse which direction the vector is pointing in coordinates according to octant way.

Pic 2:Provides info on which octant (0-7) the vector lies in,the plane is divided to 0~7 parts,the 0 part's degree  indicates  >=-22.5degree  < 22.5 degree and continue CCW

Pic3.Provides info on which quadrant(0-3) the vector lies in,the plane is divided to 0~3parts,the 0 part's degree  indicates  >=-45 degree  < 45 degree and continue CCW

2007.11.26

In the model progress,we define some bean (some interface, and abstract class) ,the class dependence explorer is as follows(UML ):

here,the interface : IRobot,  Defines the basic capabilities all robot classes should provide.
  A simple robot can detect obstacles, its position, and turn and move. 
 The intention is for this interface to be implemented for several types of physical robots

Robot, a abstract class

SimRobot,a abstract class

HardRobot,a abstract class

MoblieRobot and MySimRobot are the implemented instances

the package hierarchy is as follows:

1.the file path can't to be fix in the compatibility between application&product and the release product,in fact,our  solution is to modify manually when the application releasing in RCP,who can tell me why?

2.Add the system property after preferred in log file,here is the summary in the log

For in the currrent phase,we focus on the robot MVC design, so the UI module hasn't been designed more,here is the ugly UI,haha.... 

2007.12.06

2007.12.07

The file "config.properties","log4j.properties" will be edited by dialog in UI ,and the log file will be read-only in editor view also by date selected(haven't done)

and the map preview for user chosen by double click in editor as IE7.0 shortcut navigation as follows:

pls see the link:JAVA高质量缩略图--地图导航缩略图

2007-12-11

We can simulate the map display as Starcraft

change the log.properties

add the console output ,the detail you can refer it in the following url:

1.get the property about free memory  and total  memory in the Java Virtual Machine

2.Control system is a platform，it  serves as an agency for robots，don't care whether the  agent is real or simulated.

3.Deion.properties contains some message ,e.g. robot,obstacle,the size about game rectangle,we will support UI definition more friendly in properties file directly

In future,we will support online- game with others by TCP/IP,customer can download customized robot from DB server,which is uploaded by other customers.  customer can try to connect to query whether there are more robots uploaded.

design feature : sync TPS (turn per second) whose value is defind in configuration file or slide block.The default value is 30

PS:the tank's  velocity have been reduced and the bug in the following turn the tank can't move have been fixed.I think it may be brought by out of memory

:分包算法的程序实现,解决了报文的粘包半包现象。

2008-07-29

1.去掉(客户端)对从服务器端发过来的时间戳，VER,ID的验证,时间戳的最大值为7FFFFFFF，如果是在客户端的话，有好几个月可以累加，够用
2.把DB密码加以MD5加密后存入数据库，验证时传到service的密码也经过MD5加密(MD5加密为定长16进制32位)
3.当验证未通过就断开socket连接(如果是TCP传送，正常的client不会发非法包,既然不是正常的client，很有可能是人家在研究你的协议,不cut了他干嘛)
4.客户端时间戳的随机变动数缩小到10

Issue:

1.服务器端关闭后，好像在客户端isClosed()还是false,那么只有先断开连接，然后再接上其他的连接(已解决)

2.目前加密的ID方式BlueFish,密匙为IP+port,这样做的坏处是密匙差不多都是固定的，以后要用f(timestamp)来做密匙。

3.客户端和服务器段的游戏世界的时间戳需要不需要同步？暂时不需要

5.客户端读取效率或许可以提高，先把正行的密文给读取进来，再验证[不定长数据的话
你应该在协议的顶端加入一个长度标识
密文内容：00000021  4354 03e9 000003ea 00000005 1e5a4  e9297e55

在数据首加入4个字节的标识,用来表示数据的长度,根据这个长度来收你的密文
密文内容：[00][00][00][ff] 00000021  4354 03e9 000003ea 00000005 1e5a4  e9297e55
