go-atari-models, v1.1

The library that implements checking and generating of Atari Go moves.

Adding basic checkings of moves.

Change Log

• adding basic checkings of moves.

Features

• representing the board as an associative array of stones with their positions as keys;
• immutable applicating moves to the board via copying the latter;
• basic checkings of moves.

Examples

atarimodels.Board.CheckMove() with a legal move:

package main

import (
    "fmt"

    models "github.com/thewizardplusplus/go-atari-models"
)

func main() {
    // +-+-+-+-+-+
    // | | | | | |
    // +-+-+-+-+-+
    // | |B|W| | |
    // +-+-+-+-+-+
    // |B|W|X|W| |
    // +-+-+-+-+-+
    // | |B|W| | |
    // +-+-+-+-+-+
    // | | | | | |
    // +-+-+-+-+-+
    board := models.NewBoard(models.Size{Width: 5, Height: 5})
    for _, move := range []models.Move{
        {Color: models.Black, Point: models.Point{Column: 1, Row: 1}},
        {Color: models.White, Point: models.Point{Column: 2, Row: 1}},
        {Color: models.Black, Point: models.Point{Column: 0, Row: 2}},
        {Color: models.White, Point: models.Point{Column: 1, Row: 2}},
        {Color: models.White, Point: models.Point{Column: 3, Row: 2}},
        {Color: models.Black, Point: models.Point{Column: 1, Row: 3}},
        {Color: models.White, Point: models.Point{Column: 2, Row: 3}},
    } {
        board = board.ApplyMove(move)
    }

    move := models.Move{
        Color: models.Black,
        Point: models.Point{Column: 2, Row: 2},
    }
    fmt.Printf("%+v: %v\n", move, board.CheckMove(move))

    // Output: {Color:0 Point:{Column:2 Row:2}}: <nil>
}

atarimodels.Board.CheckMove() with an illegal move:

package main

import (
    "fmt"

    models "github.com/thewizardplusplus/go-atari-models"
)

func main() {
    // +-+-+-+-+-+
    // | | | | | |
    // +-+-+-+-+-+
    // | |B|W| | |
    // +-+-+-+-+-+
    // |B|W| |W| |
    // +-+-+-+-+-+
    // | |B|W| | |
    // +-+-+-+-+-+
    // | | | | | |
    // +-+-+-+-+-+
    board := models.NewBoard(models.Size{Width: 5, Height: 5})
    for _, move := range []models.Move{
        {Color: models.Black, Point: models.Point{Column: 1, Row: 1}},
        {Color: models.White, Point: models.Point{Column: 2, Row: 1}},
        {Color: models.Black, Point: models.Point{Column: 0, Row: 2}},
        {Color: models.White, Point: models.Point{Column: 1, Row: 2}},
        {Color: models.White, Point: models.Point{Column: 3, Row: 2}},
        {Color: models.Black, Point: models.Point{Column: 1, Row: 3}},
        {Color: models.White, Point: models.Point{Column: 2, Row: 3}},
    } {
        board = board.ApplyMove(move)
    }

    move := models.Move{
        Color: models.Black,
        Point: models.Point{Column: 3, Row: 2},
    }
    fmt.Printf("%+v: %v\n", move, board.CheckMove(move))

    // Output: {Color:0 Point:{Column:3 Row:2}}: occupied point
}
