当我的游戏打开时，我希望我的菜单出现在其他所有内容之上，但此时，菜单首先位于顶部，直到我的计时器开始，然后所有其他对象都出现在菜单顶部。如何更改它以使菜单位于顶部并且游戏仅开始播放并且计时器仅在用户单击“播放”按钮并将其带入游戏时才开始？

这是我在 Main.as 文件中的代码。我一直在尝试无济于事，因为我试图找出最简单或最有效的方法来做到这一点，但我现在对此感到非常沮丧：

package  {
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.events.TimerEvent;
import flash.utils.Timer;
import flash.ui.Mouse;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.text.TextFormat;
import flash.text.TextField;
import flash.display.Loader;
import flash.net.URLRequest;
import flash.net.URLLoader;
import flash.system.LoaderContext;

public class Main extends MovieClip {

public var gameTime:int;
public var levelDuration:int;

    public var crosshair:crosshair_mc;
static var score:Number;

var enemyShipTimer:Timer;
var enemyShipTimerMed:Timer;
var enemyShipTimerSmall:Timer;
var menu:menuMain = new menuMain;

static var scoreHeader:TextField = new TextField();
static var scoreText:TextField = new TextField();
static var timeHeader:TextField = new TextField();
static var timeText:TextField = new TextField();

public function Main()
{
    levelDuration = 30;
    gameTime = levelDuration;
    var gameTimer:Timer = new Timer(1000,levelDuration);
    gameTimer.addEventListener(TimerEvent.TIMER, updateTime);
    gameTimer.addEventListener(TimerEvent.TIMER_COMPLETE, timeExpired)
    gameTimer.start();


    scoreHeader = new TextField();
    scoreHeader.x = 5;
    scoreHeader.text = String("Score: ");
    addChild(scoreHeader);

    scoreText = new TextField();
    scoreText.x = 75;
    scoreText.y = 0;
    scoreText.text = String(0);
    addChild(scoreText);

    timeHeader = new TextField();
    timeHeader.x = 490;
    timeHeader.y = 0;
    timeHeader.text = String("Time: ");
    addChild(timeHeader);

    timeText = new TextField();
    timeText.x = 550;
    timeText.y = 0;
    timeText.text = gameTime.toString();
    addChild(timeText);

    var scoreFormat = new TextFormat("Arial Rounded MT Bold", 20, 0xFFFFFF);
    scoreHeader.setTextFormat(scoreFormat);
    scoreText.setTextFormat(scoreFormat);
    timeHeader.setTextFormat(scoreFormat);
    timeText.setTextFormat(scoreFormat);

    enemyShipTimer = new Timer(2000);
    enemyShipTimer.addEventListener("timer", sendEnemy);
    enemyShipTimer.start();

    enemyShipTimerMed = new Timer(2500);
    enemyShipTimerMed.addEventListener("timer", sendEnemyMed);
    enemyShipTimerMed.start();

    enemyShipTimerSmall = new Timer(2750);
    enemyShipTimerSmall.addEventListener("timer", sendEnemySmall);
    enemyShipTimerSmall.start();

    crosshair = new crosshair_mc();
    addChild(crosshair);

    crosshair.mouseEnabled = crosshair.mouseChildren = false;

    Mouse.hide();

    stage.addEventListener(Event.ENTER_FRAME, moveCursor);
    resetScore();
    showMenu();
}

function showMenu()
{
    stage.addChild(menu);
    Mouse.show();
    enemyShipTimer.stop();
    enemyShipTimerMed.stop();
    enemyShipTimerSmall.stop();
}

function sendEnemy(e:Event)
{
    var enemy = new EnemyShip();
    stage.addChild(enemy);
    stage.addChild(crosshair);
}

function sendEnemyMed(e:Event)
{
    var enemymed = new EnemyShipMed();
    stage.addChild(enemymed);
    stage.addChild(crosshair);
}

function sendEnemySmall(e:Event)
{
    var enemysmall = new EnemyShipSmall();
    stage.addChild(enemysmall);
    stage.addChild(crosshair);
}

static function updateScore(points)
{
    score += points;
    scoreText.text = String(score);
    var scoreFormat = new TextFormat("Arial Rounded MT Bold", 20, 0xFFFFFF);
    scoreHeader.setTextFormat(scoreFormat);
    scoreText.setTextFormat(scoreFormat);
}

static function resetScore()
{
    score = 0;
    scoreText.text = String(score);
}

function updateTime(e:TimerEvent):void
{
    trace(gameTime);
    // your class variable tracking each second, 
    gameTime--;
    //update your user interface as needed
    var scoreFormat = new TextFormat("Arial Rounded MT Bold", 20, 0xFFFFFF);
    timeText.defaultTextFormat = scoreFormat;
    timeText.text = String(gameTime);
}

function timeExpired(e:TimerEvent):void
{
    var gameTimer:Timer = e.target as Timer;
    gameTimer.removeEventListener(TimerEvent.TIMER, updateTime)
    gameTimer.removeEventListener(TimerEvent.TIMER, timeExpired)
    // do whatever you need to do for game over
}

function moveCursor(event:Event) 
{
  crosshair.x=mouseX;
  crosshair.y=mouseY;
}
}
}

我大部分时间都在试图弄清楚，但我对 Actionscript 没有太多经验。

创建两个容器（Sprites 或 MovieClips），首先添加您想要放在后面的容器，然后添加您想要放在前面的容器。现在，将菜单添加到前面的菜单中，将其他所有内容添加到后面的菜单中。
