来一份带GUI的2048 GO代码

好的，以下是一个使用Go和Ebiten库实现的2048游戏GUI代码示例： ``` package main import ( "fmt" "image/color" "math/rand" "time" "github.com/hajimehoshi/ebiten" ) const ( screenWidth = 320 screenHeight = 480 boardSize = 4 cellSize = 64 padding = 16 ) type board [boardSize][boardSize]int var ( backgroundColor = color.RGBA{0xbb, 0xad, 0xa0, 0xff} boardColor = color.RGBA{0xc2, 0xb3, 0xa1, 0xff} fontColor = color.RGBA{0x77, 0x6e, 0x65, 0xff} board board ) func (b *board) addRandom() bool { emptyCells := []int{} for i := 0; i < boardSize*boardSize; i++ { if b[i/boardSize][i%boardSize] == 0 { emptyCells = append(emptyCells, i) } } if len(emptyCells) == 0 { return false } cell := emptyCells[rand.Intn(len(emptyCells))] if rand.Float32() < 0.9 { b[cell/boardSize][cell%boardSize] = 2 } else { b[cell/boardSize][cell%boardSize] = 4 } return true } func (b *board) moveLeft() bool { moved := false for i := 0; i < boardSize; i++ { for j := 1; j < boardSize; j++ { if b[i][j] != 0 { k := j - 1 for ; k >= 0 && b[i][k] == 0; k-- { } if k >= 0 && b[i][k] == b[i][j] { b[i][k] *= 2 b[i][j] = 0 moved = true } else { k++ if k != j { b[i][k] = b[i
