你还可以用import org.papervision3d.view.BasicView;中的BasicView类来减少你的代码量
你可以看这个链接：http://leo398.blog.51cto.com/658992/130112

在添加监听后面加行代码就好使了。
addEventListener(KeyboardEvent.KEY_DOWN,onKeyDown);
addEventListener(KeyboardEvent.KEY_UP,onKeyUp);
addEventListener(Event.ENTER_FRAME, onFrame);
keylin.setFocus();

原因是因为Application没获得焦点，所以没相应到键盘事件，
init里面把随便一个组件设置下焦点。
但第一次进页面的时候，要用鼠标点一下swf，不知道你能不能忍受，我看过好多小flash游戏都是这样，上面说明让用鼠标点一下，才开始接受键盘事件

把监听优先级调到最高 试试
addEventListener(KeyboardEvent.KEY_DOWN,onKeyDown,false,(Math.pow(2,31) - 1));

不行,,,没有反应 trace(e.keyCode);
里也没有反应,,,.
