flash 图片放大，放大五次就不放大，那个大于5的地方怎么写

Question

var dogInitx:Number = image_mc.x + image_mc.width/2;
var dogInity:Number = image_mc.y + image_mc.height/2;
var cs=0;
//添加滚轮侦听
stage.addEventListener(MouseEvent.MOUSE_WHEEL,changeDogScale);
function changeDogScale(e:MouseEvent):void
{
var delt:int = int(e.delta);
image_mc.scaleX =image_mc.scaleY += delt/100;

//判断尺寸变负时赋予它最小值
if(image_mc.scaleX < 0)
{
image_mc.scaleX = image_mc.scaleY = 0.1;
return;
}
cs++;
if(cs>=5)
{
return;
}
//记录当前中心位置

}

Answer 1

function changeDogScale(e:MouseEvent):void
{
//放开头来，超过次数就退出不执行相关放大操作
cs++;
if(cs>=5)
{
return;
}

var delt:int = int(e.delta);
image_mc.scaleX =image_mc.scaleY += delt/100;

//判断尺寸变负时赋予它最小值
if(image_mc.scaleX < 0)
{
image_mc.scaleX = image_mc.scaleY = 0.1;
return;
}
//记录当前中心位置

}
