动作脚本-3:movieclip中的按钮

Question

所以，我有一个名为bg的movieclip，里面有一个名叫sleep_btn的按钮。我正在舞台上的一层上进行编码，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，如果没有在编码中定义movieclip，它将不起作用，所以我尝试了：

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

我的错误已经消失了，但我发现当我点击按钮时，健康和一天都保持不变。

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";

以及在上

健康是一部101帧的电影，编码如下：

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

编辑

顶部横幅层：

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

您没有用新数据更新实际的UI文本框。将你的日常决定代码（可能会被大规模清理，但这超出了这个问题的范围）移动到它自己的功能中，这样它就可以重用：

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（以及运行状况更新）：

function sleepClick(event:MouseEvent):void{
    health = 100;
    day = day + 1;
    //update lifebar
    lifebar.gotoAndStop(health + 1);
    //update day
    updateDay();
}

Answer 2

舞台上是否显示health和day？它们是什么类型的？您是否将TextField的文本设置为其值？

如果它们只是变量，并且没有通过UI显示，则不会看到它们发生变化。
