如何讓我的骰子游戲程序在每次擲骰時生成新的“骰子”數字

Question

每次運行程序時，都會出現相同的骰子數字。 此外，我的 while 語句最終顯示用戶和計算機獲勝。 我也只希望有多達五輪的回合，之后程序會顯示游戲的獲勝者。 我如何獲得它，以便只有數字較高的玩家贏得這一輪。

   <script>

    var computerRandomNumberOne = Math.floor((Math.random() * 10) + 1);
    var computerRandomNumberTwo = Math.floor((Math.random() * 10) + 1);
    var userRandomNumberOne = Math.floor((Math.random() * 10) + 1);
    var userRandomNumberTwo = Math.floor((Math.random() * 10) + 1);
    var userPoints;
    var computerPoints;
    var userTotal;
    var computerTotal;
    var userWin = 0;
    var computerWin = 0;

    alert("Let's shake some dice!");

        userTotal = userRandomNumberOne + userRandomNumberTwo;
        computerTotal = computerRandomNumberOne + computerRandomNumberTwo;

    while(userPoints || computerPoints != 5)
    {
        alert("Your turn to roll \n\nYou shook a " + userRandomNumberOne + " and a " + userRandomNumberTwo + ", so you have " + userTotal);

        alert("My turn to roll \n\nI shook a " + computerRandomNumberOne + " and a " + computerRandomNumberTwo + ", so I have " + computerTotal);

        if(computerTotal > userTotal)
        {
            computerWin++;
            computerPoints++;
            alert("I win " + computerTotal + " to " + userTotal + "\n\nI am winning " + computerWin + " to " + userWin);

        }
        else if(computerTotal < userTotal)
        {
            userWin++;
            userPoints++;
            alert("You win " + userTotal + " to " + computerTotal+ "\n\nYou win " + computerTotal + " to " + userTotal + "\n\nYou are winning " + computerWin + " to " + userWin);
        }
        if(computerTotal == userTotal)
        {   
            alert("Tie! Roll Again! \n\n");
        }

        if(userPoints == 5)
        {
            alert("You win the game!");
        }
        else if(computerPoints == 5)
        {
            alert("The computer wins the game!");
        }
    }

干得好！ 有幾件事是錯誤的。 在while循環的()中，|| 必須分隔完整的布爾語句。 在添加變量之前，您必須為變量賦值。 在其中一個警報中，您已連續兩次明確輸入“您贏了”短語。 如果您剛剛贏得了這一輪而不是檢查整個游戲的狀態，那么您的“我是/您正在獲勝”語句就會運行。 您不會在循環內重新計算擲骰子，因此它每次只使用相同的數字。 我假設您希望 userWin 和 computerWin 運行每個玩家贏得的整個游戲數量的總數，但它的編碼與回合總數相同（不會像他們應該的那樣每回合重置為 0）。 我相信就是這樣。 這是修改后的代碼：

var userWin = 0;
var computerWin = 0;

function play(){
    var userTotal = 0;
    var computerTotal = 0;

    var userPoints = 0;
    var computerPoints = 0;

    alert("Let's shake some dice!");

    while(userPoints < 5 && computerPoints < 5){
        var computerRandomNumberOne = Math.floor((Math.random() * 10) + 1);
        var computerRandomNumberTwo = Math.floor((Math.random() * 10) + 1);
        var userRandomNumberOne = Math.floor((Math.random() * 10) + 1);
        var userRandomNumberTwo = Math.floor((Math.random() * 10) + 1);
        userTotal = userRandomNumberOne + userRandomNumberTwo;
        computerTotal = computerRandomNumberOne + computerRandomNumberTwo;

        alert("Your turn to roll \n\nYou shook a " + userRandomNumberOne + " and a " + userRandomNumberTwo + ", so you have " + userTotal);

        alert("My turn to roll \n\nI shook a " + computerRandomNumberOne + " and a " + computerRandomNumberTwo + ", so I have " + computerTotal);

        if(computerTotal > userTotal){
            computerWin++;
            computerPoints++;

            var winningMessage = "You are winning " + userWin + " to " + computerWin;
            var computerIsWinning = (computerWin > userWin);
            if(computerWin == userWin){
                winningMessage = "We are tied " + userWin + " to " + computerWin;
            }
            else if(computerIsWinning){
                winningMessage = "I am winning " + computerWin + " to " + userWin;
            }

            alert("I win " + computerTotal + " to " + userTotal + "\n\n" + winningMessage);
        }
        else if(computerTotal < userTotal){
            userWin++;
            userPoints++;

            var winningMessage = "You are winning " + userWin + " to " + computerWin;
            var computerIsWinning = (computerWin > userWin);
            if(computerWin == userWin){
                winningMessage = "We are tied " + userWin + " to " + computerWin;
            }
            else if(computerIsWinning){
                winningMessage = "I am winning " + computerWin + " to " + userWin;
            }

            alert("You win " + userTotal + " to " + computerTotal + "\n\n" + winningMessage);
        }
        else{   
            alert("Tie! Roll Again! \n\n");
        }

        if(userPoints == 5){
            alert("You win the game!");

        }
        else if(computerPoints == 5){
            alert("The computer wins the game!");

        }
    }
    userPoints = 0;
    computerPoints = 0;
}

我已經保留了你擁有的隨機性，但如果你想讓它更干凈一點，你可以使用randojs.com讓它變得簡單。 你所要做的就是輸入：

rando(1, 10)

而不是每次都這樣：

Math.floor((Math.random() * 10) + 1)

但這是一個偏好問題！ 如果您想使用randojs.com ，只需在 HTML 文檔的 head 標簽的頂部添加以下內容：

<script src="https://randojs.com/1.0.0.js"></script>

然后您就可以改用此代碼：

var userWin = 0;
var computerWin = 0;

function play(){
    var userTotal = 0;
    var computerTotal = 0;

    var userPoints = 0;
    var computerPoints = 0;

    alert("Let's shake some dice!");

    while(userPoints < 5 && computerPoints < 5){
        var computerRandomNumberOne = rando(1, 10);
        var computerRandomNumberTwo = rando(1, 10);
        var userRandomNumberOne = rando(1, 10);
        var userRandomNumberTwo = rando(1, 10);
        userTotal = userRandomNumberOne + userRandomNumberTwo;
        computerTotal = computerRandomNumberOne + computerRandomNumberTwo;

        alert("Your turn to roll \n\nYou shook a " + userRandomNumberOne + " and a " + userRandomNumberTwo + ", so you have " + userTotal);

        alert("My turn to roll \n\nI shook a " + computerRandomNumberOne + " and a " + computerRandomNumberTwo + ", so I have " + computerTotal);

        if(computerTotal > userTotal){
            computerWin++;
            computerPoints++;

            var winningMessage = "You are winning " + userWin + " to " + computerWin;
            var computerIsWinning = (computerWin > userWin);
            if(computerWin == userWin){
                winningMessage = "We are tied " + userWin + " to " + computerWin;
            }
            else if(computerIsWinning){
                winningMessage = "I am winning " + computerWin + " to " + userWin;
            }

            alert("I win " + computerTotal + " to " + userTotal + "\n\n" + winningMessage);
        }
        else if(computerTotal < userTotal){
            userWin++;
            userPoints++;

            var winningMessage = "You are winning " + userWin + " to " + computerWin;
            var computerIsWinning = (computerWin > userWin);
            if(computerWin == userWin){
                winningMessage = "We are tied " + userWin + " to " + computerWin;
            }
            else if(computerIsWinning){
                winningMessage = "I am winning " + computerWin + " to " + userWin;
            }

            alert("You win " + userTotal + " to " + computerTotal + "\n\n" + winningMessage);
        }
        else{   
            alert("Tie! Roll Again! \n\n");
        }

        if(userPoints == 5){
            alert("You win the game!");

        }
        else if(computerPoints == 5){
            alert("The computer wins the game!");

        }
    }
    userPoints = 0;
    computerPoints = 0;
}

play();
