当我向Adobe Animate 2019中的MovieClip添加.as类时遇到以下错误:
Adobe Animate ReferenceError:错误#1069:在_上找不到属性loopMode,并且没有默认值
相同的项目适用于早期版本的Animate或flash而不会出错..as文件没什么特别之处.
solution:
打开”高级图层”时会发生此问题.您必须关闭”高级图层”才能在项目中使用某些代码.

1.转到stage的属性面板.

2.单击”高级设置”.

3.取消选中”使用高级图层”模式.

4.单击确定.

import flash.display.NativeWindowInitOptions;
import flash.display.NativeWindowSystemChrome;
import flash.display.NativeWindowType;
import flash.display.NativeWindow;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
import flash.geom.Rectangle;

var windowOptions:NativeWindowInitOptions = new NativeWindowInitOptions();
windowOptions.systemChrome = NativeWindowSystemChrome.STANDARD;
windowOptions.type = NativeWindowType.NORMAL;

var newWindow:NativeWindow = new NativeWindow(windowOptions);
newWindow.stage.scaleMode = StageScaleMode.NO_SCALE;
newWindow.stage.align = StageAlign.TOP_LEFT;
newWindow.bounds = new Rectangle(200, 200, 800, 800);

newWindow.activate();

参考：https://help.adobe.com/zh_CN/FlashPlatform/reference/actionscript/3/flash/display/NativeWindow.html#NativeWindow()

1、用animate cc 新建一个air 项目；
2、打开文件—actionScript设置—库路径—点击（浏览到本机扩展（ANE）文件）—找到我们生成的那个ANE文件
3、愉快的引用该ane中的类即可

        var settings:Settings = new Settings();
        webView = WebView.shared();
        webView.init(stage, viewport, new URLRequest("https://html5test.com"), settings, 1, 0xFFF1F1F1);
        webView.visible = true;
    }
    private function onExiting(event:Event):void {
