@hajimehoshi I'd be happy to create this example if you haven't started on it already. 😄

[hajimehoshi]

I've not created yet. I'd be glad if you could help it!

[brettchalupa]

@hajimehoshi awesome, I will give it a go and share what I end up with.

[hajimehoshi]

What's going on?

[brettchalupa]

@hajimehoshi I worked on it for a couple of days but ended up hitting a wall and getting stuck. I haven't made much progress with this. Someone else is welcome to take over if they want to.

[hajimehoshi]

OK. I was wondering if you could share your code, I'm not sure I have enough time to help this though.

[brettchalupa]

@hajimehoshi For sure, I would be happy to share what I have so far.

main.go:

package main

import (
    "log"

    "github.com/brettchalupa/ebiten-experiments/2048/twenty48"
    "github.com/hajimehoshi/ebiten"
)

func main() {
    game := twenty48.NewGame()
    update := game.Update
    if err := ebiten.Run(update, twenty48.ScreenWidth, twenty48.ScreenHeight, 1, "2048 (Ebiten Demo)"); err != nil {
        log.Fatal(err)
    }
}

twenty48/board.go:

package twenty48

import (
    "strconv"

    "github.com/hajimehoshi/ebiten"
    "github.com/hajimehoshi/ebiten/ebitenutil"
)

type Board struct {
    size  int
    tiles [][]*Tile
}

func NewBoard(size int) *Board {
    return &Board{
        size: size,
    }
}

func (board *Board) Update() error {
    return nil
}

func (board *Board) Draw(r *ebiten.Image) error {
    ebitenutil.DebugPrint(r, "Board Size: "+strconv.Itoa(board.size))

    return nil
}

twenty48/game.go:

package twenty48

import (
    "github.com/hajimehoshi/ebiten"
)

const ScreenWidth = 420
const ScreenHeight = 600
const DefaultBoardSize = 4

type Game struct {
    board *Board
}

func NewGame() *Game {
    return &Game{
        board: NewBoard(DefaultBoardSize),
    }
}

func (game *Game) Update(r *ebiten.Image) error {
    if err := game.board.Update(); err != nil {
        return err
    }

    if !ebiten.IsRunningSlowly() {
        game.Draw(r)
    }

    return nil
}

func (game *Game) Draw(r *ebiten.Image) error {
    if err := game.board.Draw(r); err != nil {
        return err
    }

    return nil
}

twenty48/tile.go:

package twenty48

const TileSize = 100

type Tile struct {
    value int
    x     int
    y     int
    color string
}

Feel free to use this or adapt it if it is of any help. My apologies for not completing it.

[hajimehoshi]

Thanks! I'll look into it later.

[hajimehoshi]

Based on your files, I've started implementing the game.

[hajimehoshi]

Works fine, very roughly though

[hajimehoshi]

I've not implemented "Game Start", "Game Over", or "Game Clear" messages, but most of 2048 features have been implemented. Let me close this issue. Thank you for your contribution again.
