ios - 为多个玩家修改swift snake and ladder game

Question

我正在尝试修改我为一个玩家在 Swift 中为一个简单的蛇梯游戏创建的代码。下面是一个成功运行的代码:

let finalSquare = 25
var playersLocation: Int = 0

var won = false

var board = [Int](count: finalSquare + 1, repeatedValue: 0)
board[03] = +08; board[06] = +11; board[09] = +09; board[10] = +02
board[14] = -10; board[19] = -11; board[22] = -02; board[24] = -08

//roll the dice
func rollDice ()->Int {
    let value = Int(arc4random_uniform(6)+1)
    return value
}

while won == false {
//roll the dice
    var advanceplayer = rollDice()
//check the position
    var advance: Int = playersLocation + advanceplayer
//check if it hits the magic number
    if playersLocation < board.count{
        var magicNumber: Int = board[playersLocation]
        advance + magicNumber
    }

    //check if player won
    if playersLocation >= board.count {
        won == true
        print("you won")
        break
    }else{
        playersLocation = playersLocation + advanceplayer
    }
}

现在代码可以运行了，我想修改为我有 3 个玩家(a、b、c)并且我想将他们插入游戏中。我几乎被困在这里:

let finalSquare = 25
var playersLocation: Int = 0
var players: [String: Int] = ["a": 0, "b": 0, "c":0]

var won = false

var board = [Int](count: finalSquare + 1, repeatedValue: 0)
board[03] = +08; board[06] = +11; board[09] = +09; board[10] = +02
board[14] = -10; board[19] = -11; board[22] = -02; board[24] = -08

board

//roll the dice
func rollDice ()->Int {
    let value = Int(arc4random_uniform(6)+1)
    return value
}

var count: Int = 0

while won == false {
    for player in players.values{


        var advanceplayer = rollDice()
        var advance: Int = player + advanceplayer


        if advance < board.count{
            var magicNumber: Int = board[advance]
            advance + magicNumber
        }

        if advance >= board.count {
            won == true
            print("you won")
            break
        }else{

        advance + advanceplayer

        }
    }
}

不知何故玩家位置没有增加，我不知道如何跟踪 a、b 或 c 是否赢得了比赛。哪里出错了？

当您更新每个玩家的位置时，您并不是将其重新分配给该玩家在 players map 中的位置。这将很难用您当前的代码来完成，因为您正在遍历 players map 的值并忽略它的键。相反，枚举键和值，更新每个玩家的位置，然后将新值粘贴回 players。
