我有一个项目在27日到期,我遇到了一个问题。每当我启动程序时,Repl.it都会崩溃。如果你查看我的代码,请在第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);
}
有一个循环。对此进行评论会使代码完美无缺。
我不知道我该尝试做什么。
它可能是我不同的东西,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;
}
}
}
我希望while语句能够找到不是所选门的门,也不是带奖品的门,而是它会崩溃。
你正在连续创建两个随机数的门牌和随机门牌,所以使用Math.random在两次连续命中时生成的相同数字很难发生。
在你的while循环中,你期望你的新随机数与你之前的两个随机数相匹配,对于一次命中/编译,它们可以是相同的,或者如果它们不相同则不能使你的while循环永远不会终止,
说a = 1,b = 2
现在期待c == a && c == b将永远不会发生,因为!= b;
在while循环中改变c将没有任何区别。所以你的逻辑是完全错误的,让我们知道你想要实现的目标,然后我们可以帮助建立逻辑
let random = () => Math.random() * 3;
let prizeDoor = Math.round(random());
console.log('prizeDoor', prizeDoor)
let randomDoor = Math.round(random());
console.log('randomDoor', randomDoor)
编辑我得到的代码工作确实改变了几位使其在我的结束像math.random一样工作,但不应该很难改变回新的stackoverflow所以花了我一段时间来弄清楚代码片段粘贴:p。

random()是Math对象的一种方法。它通过用Math.random()替换所有random()方法调用来为我工作。
我想到了。这实际上非常简单,只需更改一些操作员即可。这是最后一段代码:
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.");

}
