Question

所以问题是我无法在quizIntent处理程序的循环中循环遍历问题的数组。只显示第一个问题，然后它不再移动。其余的代码工作正常。我想要做的是继续提问，直到数组用完它们并在用户给出错误答案时突破循环。

我只是Alexa Programming的新手。请帮忙。

这是我的数组

    const got = [
    {
        question: "Grey Wind, Lady, Ghost, Shaggydog, Summer and the sixth direwolve's name is?",
        answer: 'nymeria',
    },
    {
        question: "What was the name of the sinister castle where Arya and Gendry were held prisoner in season two?",
        answer: 'harrenhal',
    },
    {
        question: "What is a person called that can enter the minds of animals?",
        answer: 'warg',
    },
    {
        question: "What was the name of the Stark ancestral sword that was melted down by Tywin Lannister?",
        answer: 'ice',
    }
];

这是我的Alexa意图

    var handlers = {
  "customIntent": function () {
           this.response.speak("Would you like to appear for a trial by combat");
      this.emit(":responseReady");
   },
   "quizIntent": function () {
       var mydecision = this.event.request.intent.slots.decision.value;
       if(mydecision=='no'||mydecision=='nope'||mydecision=='naah'){
        this.response.speak("A five year old has more courage than you.");
        this.emit(":responseReady");
       }

       for(var i = 0; i <got.length; i++){
            var myanswer = this.event.request.intent.slots.answer.value;
            var item = got[i].question;
            this.response.speak(item).listen();
            if(myanswer!=got[i].answer){
                this.response.speak("Wrong Answer. You are dead");
                this.emit(':responseReady');

            }
            if(i==got.length-1){
                this.response.speak("You won");
                this.emit(':responseReady');
            }

      }


   },
   "LaunchRequest": function () {
    this.response.speak("Valar Morghulis").listen("You are supposed to say Valar Dohareis"); 
    this.emit(":responseReady");
   }

};

这是我的意图架构，以防你想看一下

Answer 1

for循环不能用于任何目的，因为intent旨在为每次调用提供单个响应。因此，虽然你的for循环会运行，但它不会在第一次迭代的listen方法从一开始就开始执行后发出第二个响应，因为它是一个新的调用

使用会话属性可以成功实现您想要达到的目的。

var iterations = 0; //defined globally

// Later on, for every iteration, you simply need to call 
// into the attributes property of the alexa object to change the value.

this.attributes['iterations'] = iterations + 1;

我想出解决这个问题的一种方法是：

    var i = 0;
var handlers = {
  "customIntent": function () {
           this.response.speak("Would you like to take part in a trial by combat?").listen();
      this.emit(":responseReady");
   },
   "quizIntent": function () {
       var mydecision = this.event.request.intent.slots.decision.value;
       if(mydecision=='no'||mydecision=='nope'||mydecision=='naah'){
        this.response.speak("Battles have been won against harder odds! Even little Lyanna Mormont has more courage than you.");
        this.emit(":responseReady");
       }

       if(i<=got.length){
           var item = got[i].question;
           if(i == 0){
                this.response.speak("Be attentive; just like life, I won't repeat or give you a second chance. Here you go; " + item).listen();
                this.emit(":responseReady");
           }
           else {
           this.response.speak(item).listen();
           this.emit(":responseReady");
           }
        }
   },

    "answerIntent": function () {  
            var myanswer = this.event.request.intent.slots.answer.value;

            if(myanswer!=got[i].answer){
                this.response.speak("Wrong Answer. The correct answer is " + got[i].answer + ". You are dead.");
                this.emit(':responseReady');

            }
            i++;
            if(i==got.length){
                i=0;
                this.response.speak("You emerged the ultimate victor. The best in all of Planetos.");
                this.emit(':responseReady');
            }
            this.response.speak("You survived. Say ready, when you are, for the next combat!").listen();
            this.emit(':responseReady');
    },

这个想法是通过测验意图和答案意图来回切换。
