go-chess-models, v1.2

The library that implements checking and generating of chess moves.

Implementing individual checkings of moves for all types of pieces.

Change Log

• implementing individual checkings of moves for all types of pieces.

Features

• representing the board as an associative array of pieces with their positions as keys;
• immutable applicating moves to the board via copying the latter;
• checkings of moves:
  • universal;
  • individual for all types of pieces;
• generating moves via filtering from all possible ones;
• using an abstraction of a piece.

Examples

pieces.Knight.CheckMove():

package main

import (
    "fmt"

    models "github.com/thewizardplusplus/go-chess-models"
    "github.com/thewizardplusplus/go-chess-models/pieces"
)

func main() {
    board := models.NewBoard(models.Size{Width: 5, Height: 5}, []models.Piece{
        pieces.NewKnight(models.Black, models.Position{File: 2, Rank: 2}),
    })

    moveOne := models.Move{
        Start:  models.Position{File: 2, Rank: 2},
        Finish: models.Position{File: 2, Rank: 3},
    }
    fmt.Printf("%+v: %v\n", moveOne, board.CheckMove(moveOne))

    moveTwo := models.Move{
        Start:  models.Position{File: 2, Rank: 2},
        Finish: models.Position{File: 4, Rank: 3},
    }
    fmt.Printf("%+v: %v\n", moveTwo, board.CheckMove(moveTwo))

    // Output:
    // {Start:{File:2 Rank:2} Finish:{File:2 Rank:3}}: illegal move
    // {Start:{File:2 Rank:2} Finish:{File:4 Rank:3}}: <nil>
}
