Actionscript-3:电影唇中的按钮

Question

因此，我有一个名为bg的电影，里面有一个名为sleep_btn的按钮。我在舞台上做了一个图层的编码，它是这样的：

sleep_btn.addEventListener(MouseEvent.CLICK, sleepClick);
function sleepClick(event:MouseEvent):void{
    health = 100;
    day += 1;
}

我很快意识到，如果没有在编码中也定义了电影唇，它就无法工作，所以我尝试了：

bg.sleep_btn.addEventListener(MouseEvent.CLICK, sleepClick);
function sleepClick(event:MouseEvent):void{
    health = 100;
    day = day + 1;
}

我的错误消失了，但我发现，当我点击按钮，健康和白天保持不变。

日期在文本字段中，编码如下：

var day:int = 1;
if (day==1) date.text = "July 1";
if (day==2) date.text = "July 2";
if (day==3) date.text = "July 3";

不停地

健康是101帧电影，编码如下：

var health:int = 100;
   lifebar.gotoAndStop(health + 1);

编辑

顶部旗层：

stop();
var health:int = 100;
   lifebar.gotoAndStop(health + 1);
    //Can write this also: lifebar.health += 45;
    trace("health is "+health);
    trace("day is "+day);

var day:int = 1;
updateDay();

function updateDay():void{
if (day==1) date.text = "July 1";
if (day==2) date.text = "July 2";
if (day==3) date.text = "July 3";
if (day==4) date.text = "July 3";
}

fortyfivedown_btn.addEventListener(MouseEvent.CLICK, fortyfivedownClick);
function fortyfivedownClick(event:MouseEvent):void{
    if (health < 45) {
       return;
    }
    health -= 45;
    if(health < 0) health = 0;
    else if(health > 100) health = 100;
    lifebar.gotoAndStop(health + 1);
     trace("health is "+health);
}

bg.sleep_btn.addEventListener(MouseEvent.CLICK, sleepClick);
function sleepClick(event:MouseEvent):void{
    health = 100;
    day = day + 1;

    //update lifebar
    lifebar.gotoAndStop(health + 1);

    //update day
    updateDay();
}

Answer 1

您不会用新数据更新实际的UI文本框。将当天确定的代码(可以进行大规模清理，但这超出了这个问题的范围)移动到它自己的函数中，以便可以重用它：

var day:int = 1;
updateDay();

function updateDay():void{
    if (day==1) date.text = "July 1";
    if (day==2) date.text = "July 2";
    if (day==3) date.text = "July 3";
    // ...and so on...
}

然后在sleepClick处理程序中调用该函数(以及健康更新)：

function sleepClick(event:MouseEvent):void{
    health = 100;
    day = day + 1;

    //update lifebar
    lifebar.gotoAndStop(health + 1);

    //update day
    updateDay();
}

Answer 2

health和day在舞台上显示了吗？他们是哪种类型的？您是否将TextField的文本设置为它们的值？

如果它们只是变量，并且没有由UI显示，您将不会看到它们发生变化。
