Question

我已经搜索了这个，但我认为答案是如此基本，我无法找到它（我已经做了5天的闪存）

我有一堆物品，当点击一个物品时，我的物品就会上升，而且每当物品＆gt; = 1时，我想要一个不同的物体（三叶草）发光。

我使用MouseEvent进行此操作，但除非单击对象，否则无法让三叶草发光...所以很明显MouseEvent.CLICK不是我想要的。我只想让对象在我的项目＆gt; = 1后发光。下面的代码（我为了简洁而编辑了它，所以我可能已经遗漏了一些东西，但是当我运行它时我没有错误）

//import greensock
import com.greensock.*;
import flash.events.MouseEvent;

//make a variable to count items
var items = 0;

//add a click event to the clover
clover.addEventListener(MouseEvent.CLICK, payUp); //this is where i think it's wrong...

//click on b1 merch item
merch.b1.addEventListener(MouseEvent.CLICK, grabB1)

function grabB1(e: MouseEvent): void {
 //make the item disappear and add 1 to items
merch.b1.visible = false;
items++
merch.b1.removeEventListener(MouseEvent.CLICK, grabB1)
}

//explain the payUp function
function payUp(m:MouseEvent){
if (items >= 1) {
    //make the clover glow green
    TweenMax.to(clover, 0.5, {glowFilter:{color:0x66CC00, alpha:1, blurX:40, blurY:40}});
    clover.buttonMode = true;
    clover.useHandCursor = true;
    }
}

如果我理解正确，你有很多项目（代码中只显示1项以保持简单？merch.b1？）。点击其中任何一项后，如果clover var大于或等于items，您希望1发光。

如果我有这个权利，那么这应该回答你的问题（提出一些提示以减少冗余代码）。

//add a click event to the clover
clover.addEventListener(MouseEvent.CLICK, cloverClick);
//disable the ability to click the clover at first
clover.mouseEnalbled = false;
clover.mouseChildren = false;

//click listeners for your items
merch.b1.addEventListener(MouseEvent.CLICK, itemClick);

function itemClick(e:MouseEvent):void {
    //make the item disappear

    var itemClicked:DisplayObject = e.currentTarget as DisplayObject;
    //e.currentTarget is a reference to the item clicked
    //so you can have just this one handler for all the items mouse clicks

    itemClicked.visible = false;

    //if you want the item to be garbage collect (totally gone), you also need to remove it from the display (instead of just making it invisible)
    itemClicked.parent.removeChild(itemClicked);

    items++
    itemClicked.removeEventListener(MouseEvent.CLICK, itemClick);

    //now see if the clover needs to grow
    playUp();
}

//explain the payUp function
function payUp(){
    if (items >= 1) {
        //make the clover glow green
        TweenMax.to(clover, 0.5, {glowFilter:{color:0x66CC00, alpha:1, blurX:40, blurY:40}});

        //make the clover clickable
        clover.buttonMode = true;
        clover.useHandCursor = true;
        clover.mouseEnalbled = true;
        clover.mouseChildren = true;
    }
}

function cloverClick(e:Event):void {
    //do whatever you need to do when the clover is clicked
}

我应该使用什么事件（显然不是MouseEvent）[我是as3的超级新手]
