超级马里奥，我开个头，有没有一起来完成的

时间轴代码：
import flash.events.Event;
import flash.events.KeyboardEvent;
stop();
var m:CMario;
stage.addEventListener(Event.ENTER_FRAME,onEnter);
function onEnter(e:Event):void{
m = new CMario();
stage.addChild(m);
m.x=stage.stageWidth/2;
m.y=stage.stageHeight/2;
stage.removeEventListener(Event.ENTER_FRAME,onEnter);
}
stage.addEventListener(KeyboardEvent.KEY_DOWN,KeyDown);
function KeyDown(e:KeyboardEvent):void{
switch(e.keyCode){
case Keyboard.RIGHT:
m.ChangeDiection(true);
m.StartWalks();
break;
case Keyboard.LEFT:
m.ChangeDiection(false);
m.StartWalks();
break;
}
}
stage.addEventListener(KeyboardEvent.KEY_UP,KeyUp);
function KeyUp(e:KeyboardEvent):void{
switch(e.keyCode){
case Keyboard.RIGHT:
m.StopWalks();
break;
case Keyboard.LEFT:
m.StopWalks();
break;
