state.pattern.auto.shooter
----------------------------
* A study case for State design pattern implemented in Java
* A prototype for PC game or real world playful gadget(maybe robots).
* See also: source code comments
* wish list: collective intelligence as in the biology.
* wish list: use antler like tool to modify self code to be
  self-monitoring and self-evolving.

* Q & A:

20090804
--------
* Yesterday I learned about the workflow impl. in ruby, see the difference
 on impl. between state pattern and states in workflow,

* why in cpp, private 'id' property can be used in subclasses? But Java couldn't

--------
Q: As in the C2,'Making the State Base Class Reusable',
   I saw template in cpp equals Java's interface or superclass, how can I reuse code
   in java?
A:

tips: due to the limit free space on github, <300M. It is not suggested that
put the .jar files onto the source, keep jar info on .classpath, thus resolve
by hands.


Q: there is no unit test case, how shall I refactor with new ideas? Just follow
the book? Unpleasant!
hint: I guess we have no real behavior, compare with string is useless and waste
of time!
A:


Q: why cpp functions tends to use keyword 'const' for functions?
hint: see more articles on 'const'!
A:

ESP: see from the UML, Figure 2.4,
The way we introduce the global state(sharable state change), is to use a instance
property, when state changes, that property must be always be provoked.
Interesting things may happen that we have list of global state which may overshadow
the real status change?

Q: in chapter 'Adding Messaging Capabilities to Your FSM', the messagin seems to be
not nature in the first thought
e.g.  A wizard throws a fireball at an orc.  IF orc does not notice? or wizard tricks or use tactics?
e.g.  A football player makes a pass to a teammate. IF a intended missing or what?
e.g.
e.g.
Then how to implement?

--------
Q: Why do I lack new idea?
A: I am not totally in it. Try to exploit any knowledge instead of
   always being a beginner.

Q: how to implement status change between auto-pilot and human op?
   And auto-pilot has sub status, how to group them together?
A:

Q: how to do unit test for status design pattern?
A:

Q: how Unreal implements the state? like "defend the flag" or "explore map", how quickly the state change?
A:
