AS3层之间的变量和响应

Question

我在当前项目中遇到了一个小问题...我有一个对象，单击它会激活一个函数，该函数会隐藏多个对象并更改一个变量。改变所述变量然后应该导致另一层上的对象出现，但所发生的只是对象消失，而另一个没有出现......第一层的代码如下......有问题的功能是最后一个...

    exitgame.alpha=0
    voidlogomenu.alpha=0
    yes.alpha=0
    no.alpha=0
    exitprompt.alpha=0
    SwsLogoCorner.alpha=0
    yes.removeEventListener(MouseEvent.CLICK, createnewgame)
    no.removeEventListener(MouseEvent.CLICK, yesnofadeout)
}

第二个代码如下

import flash.events.Event;
import flash.system.fscommand;
import flash.events.MouseEvent;
setupplanet();
Foreground.alpha=0
function setupplanet():void
{
    Foreground.addEventListener(Event.ENTER_FRAME, PlanetLoop)
}
function PlanetLoop(e:Event=null):void
{
    if(GameMode==0){
        Foreground.alpha=0
    } else {
        Foreground.alpha=1
    }
            Foreground.gotoAndStop(1)
}

谢谢...

Answer 1

问题出在这里：

function createnewgame(e:MouseEvent)
{
    var GameMode=1;

你希望这个变量是"global"，但你将它声明为一个函数局部变量，因此在函数执行时它不存在于函数内部以外的任何地方。

至少应该是：

// Declared in the frame, should be visible
// to ALL frame functions on the same timeline.
var GameMode;

function createnewgame(e:MouseEvent)
{
    GameMode=1;
