Question

在Drug.as我有一个按钮，听众在Main，我正试图找出我点击了哪个实例，所以我可以挑出药物的价格并进行购买。

                        for (var i:int = 0; i < drugNames.length; i++)
                        {
                                randomDrugPrice = Math.random() * (i*5) + drugPrices[i];
                                drug = new Drug();

                                drugCollection.push(drug);
                            drug.setName(drugNames[i]);
                            drug.setPrice(randomDrugPrice);
                                drug.x = 0;
                                drug.y = (i * 24);
                            drug.buy.addEventListener(MouseEvent.CLICK, BuyDrug);
                        }


                        cash = new Cash();
                        addChild(cash);
                        cash.x = 100;
                        cash.y = 200;
                }

                public function BuyDrug(e:MouseEvent):void
                {
                   //How can I find out the price or id of the clicked instance?

这是我需要找出我点击的实例的地方。现在，我尝试了Drug / e.currentTarget）.getPrice（），我试过推进实例在一个向量中并挑选出一个，对我来说没有任何作用。

我可以将监听器放在类本身而不是按钮上，但这样就完成了整个过程类可点击，我有文本字段，我不希望受此影响。我该怎么办？

                }

        }

        }

}

帮助？

Answer 1

您将购买MovieClip直接添加到Drug，因此您可以假设：

public function BuyDrug(e:MouseEvent):void
{
    var drugClicked:Drug = e.target.parent as Drug;
    // more stuff here
}

（当然，你必须将听众直接添加到“购买”）

Answer 2

drug = new Drug();
drug.name = "drug"+i;

现在你可以识别哪个项目被点击了。

试图找出我点击过的6个实例中的哪一个？
