如何在 enter_frame 侦听器“animatesmoke”中获取“smokeobject”的速度属性，以引用电影剪辑“whitesmoke”，这也是“smokeobject”的属性

这是我的代码

public function createRocketSmoke() 
    {
        var smokeObject:Object = new Object();
         smokeObject.whiteSmoke = new Bitmap(new WhiteSmoke(0,0));
         smokeObject.whiteSmoke.x=targetX + Math.random()*4-8;
         smokeObject.whiteSmoke.y=targetY + Math.random()*4-8;

        smokeContainer=new MovieClip();
        smokeContainer.addChild(smokeObject.whiteSmoke);
        addChild(smokeContainer);

        var randomScale = Math.random();
        if(randomScale<.5)
        randomScale = randomScale+.5;
        smokeObject.whiteSmoke.scaleX= randomScale;
        smokeObject.whiteSmoke.scaleY= randomScale;
        smokeObject.speed = Math.random();
        smokeObject.whiteSmoke.rotation = Math.random()*360;
        smokeObject.whiteSmoke.addEventListener(Event.ENTER_FRAME,animateSmoke);    

    }
    public function animateSmoke(event:Event):void
    {
        //here i want the speed property of the 'smokeObject'
    }

你想要做的事情很快就会变得非常混乱。

我建议为你的 Smoke 创建一个类并给它一个update()函数：

public class Smoke
{

    // Properties.
    private var _whiteSmoke:Bitmap;
    private var _speed:Number = 0;


    // Constructor.
    public function Smoke(targetX:Number = 0, targetY:Number = 0)
    {
        // Prepare graphics.
        _whiteSmoke = new Bitmap(new WhiteSmoke());
        _whiteSmoke.x = targetX + Math.random()*4-8;
        _whiteSmoke. y = targetY + Math.random()*4-8;
        _whiteSmoke.rotation = Math.random()*360;
        _whiteSmoke.scaleX = whiteSmoke.scaleY = 0.5 Math.random() * 0.5;

        // Apply random speed.
        _speed = Math.random();
    }


    // Update this smoke.
    public function update():void
    {
        //
        // Update this smoke here.
        //
    }


    // The graphics for this smoke.
    public function get whiteSmoke():Bitmap
    {
        return _whiteSmoke;
    }


    // The speed for this smoke.
    public function get speed():Number
    {
        return _speed;
    }

}

这将允许您更轻松地使用数组和循环更新您的烟雾对象来更新它们中的每一个：

// This array will hold all your Smoke objects.
var allSmoke:Array = [];

// Create some Smoke.
var smoke1:Smoke = new Smoke(10, 10);
var smoke2:Smoke = new Smoke(10, 10);

// Add it to the array.
allSmoke.push(smoke1);
allSmoke.push(smoke2);


// Prepare game loop.
addEventListener(Event.ENTER_FRAME, update);
function update(e:Event):void
{
    // Loop through smoke objects and update them.
    for each(var i:Smoke in allSmoke)
    {
        i.update();
    }
}
