Question

所以，我有一个名为bg的movieclip，里面有一个名为sleep_btn的按钮。我正在舞台上的一个层上进行编码，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就行不通，所以我试过了：

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时，健康和日子保持不变。

这一天是在文本字段中，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";

以及之前和之后

健康是一个101帧的动画片段，编码如下：

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

修改的

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

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

如果它们只是变量并且UI不显示它们，您将看不到它们的变化。

Answer 2

您没有使用新数据更新实际的UI文本框。将您的日期确定代码（可以大量清理，但这超出了本问题的范围）移动到自己的功能中，以便可以重复使用：

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（和健康更新）：

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

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

    //update day
    updateDay();
}
