Question

嘿，我知道之前已经问过这个问题，但那里的人有不同的问题。

所以这是我的简单代码，这个程序将根据今天的日期显示我为每一天创建的符号。

    var day:Date = new Date();
       var today:int = day.day;

       //trace(day);

   function addpic(){

    switch(today){

                    case 1:
                    {
                        var pic:Monday = new Monday();
                        addChild(pic);
                        pic.x = 640;
                        pic.y = 200;
                    }
                    break;

                    case 2:
                    {
                        var pic:Tuesday = new Tuesday();
                        addChild(pic);
                        pic.x = 640;
                        pic.y = 200;
                    }
                    break;

                    case 3:
                    {
                        var pic:Wednesday = new Wednesday();
                        addChild(pic);
                        pic.x = 640;
                        pic.y = 200;
                    }
                    break;

                    case 4:
                    {
                        var pic:Thurday = new Thursday();
                        addChild(pic);
                        pic.x = 640;
                        pic.y = 200;
                    }
                    break;

                    case 5:
                    {
                        var pic:Friday = new Friday();
                        addChild(pic);
                        pic.x = 640;
                        pic.y = 200;
                    }
                    break;


                    case 6:
                    {
                        var pic:Saturday = new Saturday();
                        addChild(pic);
                        pic.x = 640;
                        pic.y = 200;
                    }
                    break;

                    case 7:
                    {
                        var pic:Sunday = new Sunday();
                        addChild(pic);
                        pic.x = 640;
                        pic.y = 200;
                    }
                    break;  

        }

     }

     addpic();

我认为它的原因是我多次声明了pic变量，但是我没有在一个案例中声明它，所以它不应该这样做吗？

你应该这样做：

var pic:*;

function addpic():void
{
    switch (today)
    {
        case 1 :
            pic = new Monday();
            break;
        case 2 :
            pic = new Tuesday();
            break;
        case 3 :
            pic = new Wednesday();
            break;
        case 4 :
            pic = new Thursday();
            break;
        case 5 :
            pic = new Friday();
            break;
        case 6 :
            pic = new Saturday();
            break;
        case 7 :
            pic = new Sunday();
            break;
    }
    pic.x = 640;
    pic.y = 200;
    addChild(pic);
}

addpic();

或者更简单，有一个电影剪辑“pic”（图片类）包含你的日子（7帧）：

var pic:Pic = new Pic();
pic.x = 640;
pic.y = 200;
addChild(pic);

function addpic():void
{
    pic.gotoAndStop(today);
}

addpic();

内部命名空间中的定义存在冲突
