嘿伙计们，所以基本上我想创建多个级别，我设置了如下所示的级别，但由于某种原因，level_2 的 HittestObject 没有启动。我无法确定我做错了什么。级别 2 已启动，但当我试图击中你时，它就直接通过了。

我有一个Goal_1 和一个goal_2，我想和玩家一起击球。

我想有多个级别的goal_1和多个级别的goal_2等等

这是代码：

public class keepFocusEngine extends MovieClip

    //MultiTouch added for touch gestures
    Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;


    public var btnPressedUp:Boolean;

对不起，我花了这么长时间才回复你。

以下是如何设置关卡的示例...

游戏循环（）

我只想在其中添加一个 switch 语句，让 gameLoop 知道每一帧更新哪个级别的函数。switch 语句就像一个 if...if else 条件，输入更少。switch 语句的输出取决于nLevel与可能情况的比较。因此，当nLevel等于 1 时，level_1()执行该函数。通过添加到nLevel我们可以然后更新level_2()等等。

    private function gameLoop(e:Event):void
    {
        playerShoot();
        playerControl();
        playerStageBoundaries();

        checkEndGameCondition();
        checkPlayerOffScreen();

        switch(nLevel) {
            case 1:
                level_1();
                break;
            case 2:
                level_2();
                break;
        }
    }


开始下一级（）

此函数用于去除关卡函数中的重复代码，只需调用此函数即可重置玩家位置并更新分数和关卡。

    private function startNextLevel():void
    {
        nScore += 10;
        updateHighScore();

        nLevel++;
        updatePlayerLevel();

        updatePlayerLives();

        player.x = (stage.stageWidth / 2) - 280;
        player.y = (stage.stageHeight / 2);
    }


电平函数

这些是您的关卡功能，而不是将玩家添加到每个关卡的舞台，只需重用玩家并重置其位置。

    private function level_1():void
    {

        if (player.hitTestObject(mGoal_1))
        {

            trace("Goal_1 Collision");
            //Remove button for constant movement
            btnShootPlayer = false;
            mGoal_1.destroyGoal_1();
            player.destroyPlayer();

            startNextLevel();
        }
        else
        {
            checkEndGameCondition();
        }
    }

    private function level_2():void
    {
        //Keep Text Scores initiated


        if (player.hitTestObject(mGoal_2))
        {   
            mGoal_2.destroyGoal_2();
            player.destroyPlayer();

            btnShootPlayer = false;
            startNextLevel();
        } else {
            checkEndGameCondition();
        }

    }
