Java Chess

Description

I wanted to attempt to simulate chess. model it without checking how others had done it before, Pseudo code it and then implement those design decisions to get a working Chess Game.

to this i needed to define Pieces, Player,Board Game and Square Objects.

I utilize static methods heavily at this time to allow for continuity and there is substantial re factoring required regards allowing for multiple game instances.

• when a player chooses one of their available pieces, Based on the piece type an array of allowed moves is generated using the current layout of the board.
• The possible movement of the pieces are then highlighted on the board.
• if and when the player chooses one of the allowed moves the board gets updated, checking for a check scenario, if the move was legal the game continues swapping the board
• the check algorithm utilities a two step optimization approach, removing most of the brute force checks on each cycle.
• although it is unable to move into check, the game itself does not currently define a checkMate scenario at this time.

I have used Third party Icons for the pieces, and have used photo shopped images of marble for the board effect.

I have a checkMate algorithm that is not fully functional  and is mostly Pseudo at this time .

as I am tempted to make a stab at creating an AI Object to play as the second player, this algorithm is subject to change.

EDIT -15.12-14

V1.2 alpha

-Added “Optimist Prime” my naive AI Algorithm( very slow and full of wishful thinking). the AI operates given the current state of the board it plays the next 3 moves for each piece against all enemy possible moves to 3 scenarios, this semi-brute force approach is woefully slow taking 40sec or so to return when Queens have a full range of motion.

– the Alogrithim currently focuses on the best possible outcome rather than assuming the enemy will play to their advantage! (Hence Optimist).

-Optimization of this algorithm is very much needed including a refusal to recommend a negative Check scenario as best option.

-Players have the option to play with another Human or against the AI.

-Minor bug fixes

-Major bugs added 😛

– WARNING  – This is very much Alpha, the AI System uses (Wastes) large amount of RAM hitting over 4Gigs at one stage in testing

TRY IT!
