javascript - 垄断 : check for double only if player lands naturally

Question

在《大富翁》中，当玩家落在机会或社区宝箱上时，会抽出一张牌，可能会指示玩家前进到不同的位置，在这种情况下，即使玩家掷出双倍，该玩家的回合也结束了。我正在尝试将这个功能合并到我的代码中。 Here is a spreadsheet plan of my code.

问题是我应该将checkDouble放在什么级别。我想检查玩家是否通过掷骰子到达那里，而不是当玩家被纸牌移动时是否出现 double 。

当玩家点击购买时，checkDouble 已经运行，changeTurn 也已运行，因此错误的玩家被分配到购买的属性(property)。

我没有包含我的所有代码，即 455 行代码。我希望我提供了足够的代码。

function gameEngine(){
    clearContent();
    rollDice();
    drawDice(dice1, dice2);
    processDice(); 
    updatePos();    
    movePiece();
    checkPurchasable();
    checkDouble();// this is a problem, because by the time the player clicks the buy button, checkDouble has run and hence changeTurn.
}

function checkPurchasable(){
    if (getPurchasable()) {
        checkForsale();
    } else {
        nonPurchasable();
    }
}

function checkForsale() {
    if (getOwner() == "unowned") {
        toggleButtons();
        if ($(".action-card").is(":visible")) {
        $(".action-card").delay(1000).fadeOut('slow', function() {
            $(".deed-card").toggle();   
        });
        } else {
        $(".deed-card").toggle();   
        }

        switch (true) {
        case (getType() == "city"):
                showDeedCard();
                break;
            case (getType() == "airport"):
                showAirportCard();
                break;
            case (getType() == "utility"):
                showUtilityCard();
                break;
        }   
    } else {
        payRent();
    }
}

function nonPurchasable() {
    switch(true) {
        case (getType() == "chest"):
            drawCard(player, chest, "Community Chest");
            break;
        case (getType() == "tax"):
            updateBalance(getTax()*-1,player);
            break;
        case (getType() == "chance"):
            drawCard(player, chance, "Chance");
            break;
        case (getType() == "corner"):
            break;
    }
}

function Buy() {
    $(".deed-card").slideToggle();
    toggleButtons();
    assignOwner();
    updateBalance(getPrice()*-1,player);
    var x = getTitle();
    var xx = x.substring(0,3);
    var res = xx.toUpperCase();
    if (getType() != "city") {
        $("#assets"+player).append('<span class="black">' + res + '</span>');
    } else {
        showPrice();
        var set = positions[pos].set;
        $("#assets"+player).append('<span class="' + set + '">' + res + '</span>');
    }
}

function drawCard(player, deck, title) {
    var card = deck.shift();
    flipCard(card.instruction, title);
    card.act(player);
    deck.push(card);
}

function assignOwner() {
    positions[pos].owner = player;
}

function changeTurn() {
    player = 1 - player;
}

function checkDouble() {
    if (isDouble) {
        dblRolls++;
    } else {
        dblRolls = 0;
        changeTurn();
    }
}

function AbsMoveCard(instruction, destination) {
    this.instruction = instruction;
    this.destination = destination;
}

AbsMoveCard.prototype.act = function(player) {
    pos = this.destination;
    if (pos == 0 || pos<players[player].pos) {
        updateBalance(200, player);
    }
    isDouble = false;
    updatePos();
    movePiece();
    checkPurchasable();
};

function RelMoveCard(instruction, distance) {
    this.instruction = instruction;
    this.distance = distance;
}

RelMoveCard.prototype.act = function(player) {
    alert("Moving relative.");
    pos -= this.distance;
    isDouble = false;
    updatePos();
    movePiece();
    checkPurchasable();
};

如果掷骰子时您为 rolledDoubles 设置了一个标志，那么当您跟随 pickcard 进入移动时，您可以清除该标志。对于终端节点处的所有其他路径，请检查标志 rolledDoubles，如果设置了该标志，则调用新的“letPlayerKnow TheyCanRollAgain”，该标志将调用 rollDice。

您的电子表格有助于可视化每个点的各种选择。我对《大富翁》的规则感到生疏。
