我正在尝试在 AS3 Non-OOP 中编写一个简单的程序（我直接对时间线进行编码），但我的函数“选择”没有像应有的那样被调用。事实上，它根本没有被调用，我也没有收到编译器错误。这是我的代码：

//Black jack game
import flash.events.Event;
import flash.ui.Mouse;
import flash.events.KeyboardEvent;
import flash.ui.Keyboard;
addEventListener(Event.ENTER_FRAME,talk);

stop();
var yourHand1:Number = 0;
var cHand1:Number = 0;
var yourHand2:Number = 0;
var cHand2:Number = 0;

function talk(e:Event){

    if(yourHand1 < 3){
        yourHand1 +1;
    }
    if(cHand1 < 3){
        cHand1 +1;
    }
    cHand1 = 1+Math.floor(Math.random() * 11);
    yourHand1 = 1+Math.floor(Math.random()* 11);
    trace(cHand1);  
    trace(yourHand1);
    cHand.text = cHand1.toString();
    yourHand.text = yourHand1.toString();
    removeEventListener(Event.ENTER_FRAME, talk);
    //choices();
}

addEventListener(KeyboardEvent.KEY_DOWN,choices);

function choices(event:KeyboardEvent){
    trace("Would you like to hit or stay?");
    trace("Press left arrow to hit, space bar to stay");
    if(event.charCode == 65){
        trace("You have chosen to stay");
    }
    if(event.charCode == 66){
        letsDoItAllAgain();
    }
}


function letsDoItAllAgain(){

    if(yourHand2 <= 2){
        yourHand2 +2;
    }
    if(cHand2 <= 2){
        cHand2 +2;
    }
    cHand2 = 1+Math.floor(Math.random() * 11);
    yourHand2 = 1+Math.floor(Math.random()* 11);
    trace(cHand2);  
    trace(yourHand2);
    cHand.text = (cHand2 + cHand1).toString();
    yourHand.text = (yourHand1 + cHand2).toString();
    removeEventListener(Event.ENTER_FRAME, letsDoItAllAgain);
}

尝试在舞台上添加 eventListener。

stage.addEventListener(KeyboardEvent.KEY_DOWN,choices);

另外潘说：

stage.addEventListener(KeyboardEvent.KEY_DOWN,choices);

重要的是要知道您可能会失去主窗口的焦点。我的项目中有一些类似的东西（在时间轴上也是如此），我必须定期调用这个（当我知道可能会失去焦点时）：

stage.focus = stage;
