as3 砖块程序
我复制了18x6个对象

init();var brick:MovieClip; function init():void {   for (var i=0; i<18; i++) {    for (var j=0; j<6; j++) {     brick=new MovieClip();     addChild(brick);     brick.x=i*30;     brick.y=j*10;     brick.name="brick"+i+j;     trace(brick.name);    // brick.addEventListener(Event.ENTER_FRAME,hitonEnterFrame);    }   } }
