actionscript 3-如何将变量传递给新的孩子?[闪光AS3]

Question

代码很好地说明了这个问题，我已经删除了所有不相关的内容。

游戏开始时创建2-4个亲属

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");
        }
    }
}

亲属创建功能

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

亲属类

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");
        }
    }
}

输出应该是：

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

但取而代之的是：

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

这意味着arrivalType变量没有被传递。它似乎是可以传递的硬编码变量，因此目前我在亲属移动中有一个阿尔法为0的正方形，它的x位置决定了构造函数中rrivalType的值，但这肯定不是一个好的做法，有更好的方法吗？

我认为您只想修改kinsmen类的构造函数，以接受arrivalType和name的参数。

您当前正在做的是构建一个新的kinsmen对象，然后在该对象上设置arrivalType和name。因此，当构造函数代码运行时，arrivalType是int的默认值，即0。

在kinsmen类中这样修改构造函数：

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");
    }
}

并修改createKinsmen()函数，使其将arrivalType的值传递给构造函数方法，而不是在创建对象后设置arrivalType和name：

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