将konami代码实现到flex应用程序中的最好方法是什么？

我想创建一个组件将其添加到我所有的proyects，只是为了好玩。

谢谢

更新：我做了一个简单的组件，感谢ZaBlanc

测试它

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" xmlns:konamicode="konamicode.*">
    <mx:Script>
        <![CDATA[
            import mx.controls.Alert;
        ]]>
    </mx:Script>
    <konamicode:KonamiCodeCatch success="Alert.show('+30 lives!!!')" />
</mx:Application>

解决方法

状态机是有趣的写，但在这种情况下，我会去签名模式。根据你想放置处理程序(在组件的阶段)的位置，这里有一些代码应该工作，虽然你可以收紧它(当然，根据你的特定需要定制它)：

// up-up-down-down-left-right-left-right-B-A
public static const KONAMI_CODE:String = "UUDDLRLRBA";

// signature
private var signatureKeySequence:String = "";

private function onKeyDown(event:KeyboardEvent):void {
    var keyCode:int = event.keyCode;

    switch (keyCode) {
        case Keyboard.UP:
            signatureKeySequence += "U";
            break;

        case Keyboard.DOWN:
            signatureKeySequence += "D";
            break;

        case Keyboard.LEFT:
            signatureKeySequence += "L";
            break;

        case Keyboard.RIGHT:
            signatureKeySequence += "R";
            break;

        case Keyboard.B:
            signatureKeySequence += "B";
            break;

        case Keyboard.A:
            signatureKeySequence += "A";
            break;

        default:
            signatureKeySequence = "";
            break;
    }

    // crop sequence
    signatureKeySequence = signatureKeySequence.substr(0,KONAMI_CODE.length);

    // check for konami code
    if (signatureKeySequence == KONAMI_CODE) {
        // 30 lives!
    }
}
