Deferred action

[olufjen]

Create an action during the planning procedures.
An example:
We need a plan for castling.
Step one:
We want to move Whitebishop2. Then we must first move WhitePawn5.
Create an ActionSchema
initState of Pawn
goalState of Bishop.

If such an actionSchema exists then find actionSchema for Pawn and execute.
Wait for opponent
Then find actionSchema for Bishop and execute.,
Wait for opponent

At present chessactions are created as part of the minimax search process.
When created the chessaction is given a AgamePiece, its reachable positions and the player who owns the piece.
Based on this the chessaction creates a possible move for this piece.

A deferred action is created with the following in mind:
I want to move a certain piece to a certain position.
I need to determine which piece I want to move.
I need to determine what position I want to mover it to.
I need the following information to achieve this:

• Where are the opposing pieces?
• What positions do they threaten?
• What opposing pieces can I take?, and to what cost?

The Chesspiece has a calculated value: Pawn = 1, Rook = 5, Bishop ans Knight = 3, Queen = 9.
The King has default value 0.

The Problem object uses permutations to calculate other actions. It uses all constants in all positions of the preconditions and effects.
This is shown in the enclosed file.

Corrected

[olufjen]

After White castling the white Rook has the following positions:
The removed positions are not cleared?
The removed positions are calculated by the PreferredMove Processor
This is called when the ChessAction is created and by the player's calculatePreferredPosition method

[olufjen]

The black castle disappeared:
This happens when black performs castling

The "correct" castling:

See code for explaination

[olufjen]

Create diagrams for the default part of the checkMovenumber method !!!

[olufjen]

OBS The castling move notation here:

The castle has been moved
castle.setCastlingMove(true);
movedPiece.setCastlingMove(true);
This must reset after castling?

[olufjen]

After successful castling:

Caused by: java.lang.NullPointerException
at no.chess.web.model.PlayGame.proposeMove(PlayGame.java:307)
at no.chess.web.server.resource.RapporterChessStartServerResourceHTML.storeChess(RapporterChessStartServerResourceHTML.java:808)

The chessAgent returned an action that is null

My WhitePawn5 is threatened, but it cannot be moved!!!!

[olufjen]

A "no-move" after the castling:
The rook is "moved" back to its original position.

There should be a move after Bishop Bf5
