Question

我正在关注Adobe关于检测屏幕尺寸的教程。我正在努力使屏幕最适合IOS和Android设备。

这是一个很棒的教程，我得到了代码：http://www.adobe.com/devnet/air/articles/multiple-screen-sizes.html

但是，当我使用术语“base”时，正如他们在本教程中所建议的那样，我收到以下错误。 1120：访问未定义的属性库。

以下是我收到错误的代码：

// scale the entire interface 
base.scale = appScale;
// map stays at the top left and fills the whole screen 
base.map.x = 0;

这是我在函数中使用的代码，减去包中两个vars的声明。

public function theScreen()
        {
            guiSize = new Rectangle(0,0,1024,600);
            deviceSize = new Rectangle(0,0,Math.max(stage.fullScreenWidth,stage.fullScreenHeight),Math.min(stage.fullScreenWidth,stage.fullScreenHeight));
            W.text = "" + deviceSize.width + "";
            H.text = "" + deviceSize.height + "";

            var appScale:Number = 1;
            var appSize:Rectangle = guiSize.clone();
            var appLeftOffset:Number = 0;
            // if device is wider than GUI's aspect ratio, height determines scale 
            if ((deviceSize.width/deviceSize.height) > (guiSize.width/guiSize.height))
            {
                appScale = deviceSize.height / guiSize.height;
                appSize.width = deviceSize.width / appScale;
                appLeftOffset = Math.round((appSize.width - guiSize.width) / 2);
            }
            else
            {
                appScale = deviceSize.width / guiSize.width;
                appSize.height = deviceSize.height / appScale;
                appLeftOffset = 0;
            }
            // scale the entire interface 
            base.scale = appScale;
            // map stays at the top left and fills the whole screen 
            base.map.x = 0;

        }

如何访问Adobe所指的“基础”类？
