Question

我在AS3中制作了一个非常简单的JRPG战斗系统。我有一个名为输出的文本框，显示战斗事件。嵌入了字体（我已经检查了十几次）。它是在黑背景的白色文本。显示初始文本，但之后不会更新。我有代码集来跟踪发生了什么，并正确显示。我究竟做错了什么？感谢。

这是代码（显然这不完整）：

function BattleSystem():void
        {
            //add battle system event listeners
            stage.addEventListener(KeyboardEvent.KEY_DOWN,onKeyDown);
            stage.addEventListener(KeyboardEvent.KEY_UP, onKeyUp);

            //initialize battle
            this.gotoAndStop(2);
            battleStart = true;
            playerAtks = false;
            output.text = ""
            output.text = "A dangerous " + _enemyName + " threatens to attack! What will you do? 1. Attack 2. Spells 3. Items ";


            function onKeyDown(event:KeyboardEvent):void
                {           

                    if (event.keyCode == Keyboard.NUMBER_1)
                    {
                        playerDmg = uint(_Str * ((Math.random() + 1)) - _enemyDef);
                    }
                }
            function onKeyUp(event:KeyboardEvent):void
            {
                if (event.keyCode == Keyboard.NUMBER_1)
                {
                    trace("You deal " + playerDmg + " damage to the " + _enemyName + "!")
                    output.text = "You deal " + playerDmg + " damage to the " + _enemyName + "!";
                }
            }
        }

例如，目前当我参加战斗时，输出显示“危险的粘液威胁要攻击！你会做什么？1。攻击2.法术3.物品”。但是当我点击1时，输出不会改变。

你的事件处理程序封装在函数中，这是不对的。

试试这个：

function BattleSystem():void
{
     //add battle system event listeners
     stage.addEventListener(KeyboardEvent.KEY_DOWN,onKeyDown);
     stage.addEventListener(KeyboardEvent.KEY_UP, onKeyUp);

     //initialize battle
     this.gotoAndStop(2);
     battleStart = true;
     playerAtks = false;
     output.text = ""
     output.text = "A dangerous " + _enemyName + " threatens to attack! What will you do? 1. Attack 2. Spells 3. Items ";

}

function onKeyDown(event:KeyboardEvent):void
{           

      if (event.keyCode == Keyboard.NUMBER_1)
      {
          playerDmg = uint(_Str * ((Math.random() + 1)) - _enemyDef);
      }
}

function onKeyUp(event:KeyboardEvent):void
{
    if (event.keyCode == Keyboard.NUMBER_1)
    {
         trace("You deal " + playerDmg + " damage to the " + _enemyName + "!")
         output.text = "You deal " + playerDmg + " damage to the " + _enemyName + "!";
     }
}

文本框不会在Flash AS3中更新
