在Repl.it（P5.js）中的While语句崩溃选项卡

Question

我有一个项目将于27日到期，并且遇到了问题。每当我启动程序时，Repl.it就会崩溃。如果您查看我的代码，请参见第42行：

//getting a number that isnt the players door or the prize door
  while ((randomDoor2 == prizeDoor) || (randomDoor2 == randomDoor)) {
    setTimeout(
      function(){ 
        randomDoor2 = Math.round(random(1,3));
      }, 
      10000);
  }

有一个while循环。注释掉该代码可使代码完美运行而不会出现滞后。

我不知道该怎么做

可能不是我的一段时间，所以这是我的整个script.js：

var chance; // swap | dont swap
var prizeDoor;
var randomDoor;
var randomDoor2;
var randomDoor3;
var decide;

function setup() {
  chance = 50;
  createCanvas(1000,1000);
}

function draw() {
 //setting up round

  prizeDoor = Math.round(random(1,3));

  //choosing first door

  console.log("[1] [2] [3]");
  randomDoor = Math.round(random(1,3));

  //showing user the door AI picks
var chance = 50; // swap | dont swap
var prizeDoor;
var randomDoor;
var randomDoor2;
var randomDoor3;
var decide;

function setup() {
  chance = 50;
  createCanvas(1000,1000);
}

function draw() {
 //setting up round

  prizeDoor = Math.round(random(1,3));

  //choosing first door

  console.log("[1] [2] [3]");
  randomDoor = Math.round(random(1,3));

  //showing user the door AI picks

  if (randomDoor == 1) {
    console.log(" ^");
    console.log(" |");
  } else if (randomDoor == 2) {
    console.log("     ^");
    console.log("     |");
  } else {
    console.log("         ^");
    console.log("         |");
  }

  console.log("AI chooses door #" + randomDoor + ".");

  //revealing a door

  //getting a number that isnt the players door or the prize door
  while ((randomDoor2 == prizeDoor) || (randomDoor2 == randomDoor)) {
    setTimeout(
      function(){ 
        randomDoor2 = Math.round(random(1,3));
      }, 
      10000);
  }

  //showing this to the user
  console.log("");
  console.log("Door #" + randomDoor2 + " does not have the prize.");

  //having the computer make a desicion
  if (random(0,100) < chance) {
    decide = "swap doors.";
    while ((randomDoor3 !== randomDoor2) || (randomDoor3 !==  randomDoor)) {
      randomDoor3 = Math.round(random(1,3));
    }
  } else {
    decide = "keep the current door.";
  }

  //letting the user know of the computer's desicion
  console.log("");
  console.log("The AI chose to " + decide);

  // figuring out if the AI won
  if (randomDoor3 == prizeDoor || randomDoor == prizeDoor) {

    console.log("AI won!");

    if (decide == "swap doors.") {
      chance -= 5;
    } else {
      chance += 5;
    }
  } else {

    console.log("AI lost.");

    if (decide == "swap doors.") {
      chance += 5;
    } else {
      chance -= 5;
    }
  }
}

我想用while语句找到既不是选定的门，也不是带有奖品的门，但它崩溃了。

编辑我让代码可以工作，但确实做了一些修改，使其可以像math.random这样在我的终端上工作，但是应该不难变回新的stackoverflow，所以花了我一段时间来弄清楚代码段粘贴：p。

<script type="text/javascript">

var chance; // swap | dont swap
var prizeDoor;
var randomDoor;
var randomDoor2;
var randomDoor3;
var decide;
var chance = 50;
function setup() {
  createCanvas(1000,1000);
}

function draw() {
 //setting up round

  prizeDoor = Math.floor((Math.random() * 3) + 1);
  console.log(prizeDoor+" prizeDoor");

  //choosing first door
  console.log("[1] [2] [3]");
  randomDoor = Math.floor((Math.random() * 3) + 1);
  randomDoor2 = Math.floor((Math.random() * 3) + 1);
  randomDoor3 = Math.floor((Math.random() * 3) + 1);


  //showing user the door AI picks

  if (randomDoor == 1) {
    console.log(" ^");
    console.log(" |");
  } else if (randomDoor == 2) {
    console.log("     ^");
    console.log("     |");
  } else {
    console.log("         ^");
    console.log("         |");
  }



  console.log("AI chooses door #" + randomDoor + ".");


  //revealing a door

  //getting a number that isnt the players door or the prize door
  while ((randomDoor2 == prizeDoor) || (randomDoor2 == randomDoor)) {
   randomDoor2 = Math.floor((Math.random() * 3) + 1);
  }

  //showing this to the user
  console.log("");
  console.log("Door #" + randomDoor2 + " does not have the prize.");

  //having the computer make a desicion
  if (Math.floor((Math.random() * 100) + 1) < chance) {
    decide = "swap doors.";
    while ((randomDoor3 == randomDoor2) || (randomDoor3 == randomDoor)) {
      randomDoor3 = Math.floor((Math.random() * 3) + 1);
    }
  } else {
    randomDoor3 = randomDoor;
    decide = "keep the current door.";
  }

  //letting the user know of the computer's desicion
  console.log("");
  console.log("The AI chose to " + decide);

  // figuring out if the AI won
  if (randomDoor3 == prizeDoor) {

    console.log("AI won!");

    if (decide == "swap doors.") {
      chance -= 5;
    } else {
      chance += 5;
    }
  } else {

    console.log("AI lost.");

    if (decide == "swap doors.") {
      chance += 5;
    } else {
      chance -= 5;
    }
  }
}

draw();
</script>

Answer 2

您要连续创建两个随机数prizeDoor和randomDoor，因此很难用Math.random在两个连续命中时生成相同的数字。

在while循环中，您希望您的新随机数现在与您以前的两个随机数匹配一次命中/编译，它们可以相同或不相同，如果它们不相同，那么使用while循环将毫无用处终止，

说a = 1和b = 2

现在 期望c == a && c == b永远不会发生，因为a！= b;

在while循环中更改c不会有任何区别。 所以您的逻辑是完全错误的，让我们知道您要达到的目标，也许我们可以帮助您建立逻辑

let random = () => Math.random() * 3;
let prizeDoor = Math.round(random());
console.log('prizeDoor', prizeDoor)
let randomDoor = Math.round(random());
console.log('randomDoor', randomDoor)

Answer 3

random（）是Math对象的一种方法。 它通过用Math.random（）替换所有random（）方法调用为我工作。

Answer 4

我知道了。实际上很简单，只需更改一些运算符即可。这是最后的代码：

var chance = 50; // swap | dont swap
var prizeDoor;
var randomDoor;
var randomDoor2;
var randomDoor3;
var decide;

function setup() {
  chance = 50;
  createCanvas(1000,1000);
}

function draw() {
 //setting up round

  prizeDoor = Math.round(random(1,3));

  //choosing first door

  console.log("[1] [2] [3]");
  randomDoor = Math.round(random(1,3));

  //showing user the door AI picks

  if (randomDoor == 1) {
    console.log(" ^");
    console.log(" |");
  } else if (randomDoor == 2) {
    console.log("     ^");
    console.log("     |");
  } else {
    console.log("         ^");
    console.log("         |");
  }

  console.log("AI chooses door #" + randomDoor + ".");

  //revealing a door

  //getting a number that isnt the players door or the prize door
  while ((randomDoor2 == prizeDoor) || (randomDoor2 == randomDoor)) {
    setTimeout(
      function(){ 
        randomDoor2 = Math.round(random(1,3));
      }, 
      10000);
  }

  //showing this to the user
  console.log("");
  console.log("Door #" + randomDoor2 + " does not have the prize.");

  //having the computer make a desicion
  if (random(0,100) < chance) {
    decide = "swap doors.";
    while ((randomDoor3 == randomDoor2) || (randomDoor3 ==  randomDoor)) {
      randomDoor3 = Math.round(random(1,3));
    }
  } else {
    decide = "keep the current door.";
  }

  //letting the user know of the computer's desicion
  console.log("");
  console.log("The AI chose to " + decide);

  // figuring out if the AI won
  if (randomDoor3 == prizeDoor || randomDoor == prizeDoor) {

    console.log("AI won!");

    if (decide == "swap doors.") {
      chance -= 5;
    } else {
      chance += 5;
    }
  } else {

    console.log("AI lost.");

    if (decide == "swap doors.") {
      chance += 5;
    } else {
      chance -= 5;
    }
  }
}
