这是我的游戏里面创造怪物的函数：
public function makemonster(xx:int,t:int)
{
var symbolName:String = "Mst" + t.toString();
var symbolClass:Class = getDefinitionByName(symbolName) as Class;
var s:* = new symbolClass ;
s.sceneid = Main.monster.length;
Main.monster.push(s);
Main.formst.addChild(s);
s.x = xx;
s.y = 418;
s.stop();
}
