如何將變量傳遞給新孩子？ [flash AS3]

Question

該代碼很好地說明了這個問題，我已經刪除了所有無關的內容。

游戲開始時創建2-4個親屬

function createInitialKinsmen()
{
    for (var k:int = 1; k < 3 + Math.round(Math.random() * 2; k++)
    {
        if (k == 1)
        {
            createKinsmen(0);
            trace ("player");
        }
        else
        {
            createKinsmen(1);
            trace ("starting kinsmen");
        }
    }
}

親屬創建功能

function createKinsmen(arrivalTypeVar:int)
{
    var newKinsmen = new kinsmen;
    listPanel.kinsmenDivider.addChild(newKinsmen);
    totalKinsmen++;
    totalKinsmenAlive++;
    newKinsmen.name = "kinsmen" + totalKinsmen;
    newKinsmen.arrivalType = arrivalTypeVar;
}

親屬班

public class kinsmen extends MovieClip
{
    var arrivalType:int;
    function kinsmen()
    {
        trace(this.name);
        if (this.arrivalType = 0)
        {
            trace("player");
        }
        if (this.arrivalType = 1)
        {
            trace("starting kinsmen");
        }
    }
}

輸出應顯示：

kinsmen1
player
player
kinsmen2
starting kinsmen
starting kinsmen
kinsmen3
starting kinsmen
starting kinsmen
kinsmen4
starting kinsmen
starting kinsmen

而是說：

kinsmen1
player
player
kinsmen2
player
starting kinsmen
kinsmen3
player
starting kinsmen
kinsmen4
player
starting kinsmen

這意味着沒有傳遞arrivalType變量。 這似乎是硬編碼的變量可以被傳遞，雖然這樣的時刻我有阿爾法0的親屬影片剪輯內方，它的x位置決定arrivalType的值在構造函數中，但這肯定不能很好的做法，是有更好的方法嗎？

我認為您只想修改kinsmen類的構造函數，以接受arrivalType和name的參數。

你當前做的是構建一個新的kinsmen對象，之后設置arrivalType和name該對象上。 因此，當構造函數代碼運行時， arrivalType是int的默認值，該值為0。

像這樣在kinsmen類中修改構造函數：

function kinsmen(arrivalType:int, name:String)
{
    this.name = name;
    this.arrivalType = arrivalType;
    if (this.arrivalType == 0)
    {
        trace("player");
    }
    if (this.arrivalType == 1)
    {
        trace("starting kinsmen");
    }
}

和修改createKinsmen()函數，使其在經過了一個值arrivalType給構造方法，而不是設置arrivalType和name創建對象后：

function createKinsmen(arrivalTypeVar:int)
{
    totalKinsmen++;
    totalKinsmenAlive++;
    var newKinsmen = new kinsmen(arrivalTypeVar, "kinsmen" + totalKinsmen);
    listPanel.kinsmenDivider.addChild(newKinsmen);
}
