请问这个定义类有什么问题
为什么这个类中定义的所有属性在输出时都是未定义的呢？谢谢指教
class landByMouse{
var allrat=12,time=60,score=0,highscore=60,lowscore=15,loop=0;
function timeshow() //设置计时器
{
_root.time=_root.time-1;
}

{
loop=loop+1;

var mouse_y=Math.floor(Math.random()*400)+1;

_root["landMouse"+loop]._x=mouse_x;
_root["landMouse"+loop]._y=mouse_y;
