This is a game where the player plays against the computer in a rock paper scissors game. I am trying to make the computer score or player score go up depending on which one wins. But it does not increment when I try to run it. I am new to functions and returning values so I do not really understand it.
// Declaring variables
let playerScore = 0;
let computerScore = 0;
// Gives a random value from the array
function computerPlay(){
var things = ['rock', 'paper', 'scissors'];
var random = things[Math.floor(Math.random()*things.length)];
console.log('The computer chose: ' + random);
return random;
}
// plays a round of the game
function playRound(playerSelection, computerSelection){
if(playerSelection === computerSelection){
console.log("tie");
}
else if(playerSelection === "rock" && computerSelection === "paper"){
console.log("YOU LOSE");
computerWin();
}
else if(playerSelection === "rock" && computerSelection === "scissors"){
console.log("YOU WIN");
playerWin();
}
else if(playerSelection === "paper" && computerSelection === "rock"){
console.log("YOU WIN");
playerWin();
}
else if(playerSelection === "paper" && computerSelection === "scissors"){
console.log("YOU LOSE");
computerWin();
}
else if(playerSelection === "scissors" && computerSelection === "paper"){
console.log("YOU WIN");
playerWin();
}
else{
console.log("YOU LOSE");
computerWin();
}
}
function playerWin(){
++playerScore;
console.log("Player Score is " + playerScore);
}
function computerWin(){
++computerScore;
console.log("Computer Score is " + computerScore)
}
// Call functions
let chooseWord = "Choose ";
let playerSelection = prompt(chooseWord);
console.log(playerSelection.toLowerCase());
let computerSelection = computerPlay();
computerSelection.toLowerCase();
playRound(playerSelection, computerSelection);
computerWin();
playerWin();
Overall code works well. The improvement to make it a game is to create a loop for a given score (here is to 3 wins).
// Declaring variables
let playerScore = 0;
let computerScore = 0;
// Gives a random value from the array
function computerPlay(){
var things = ['rock', 'paper', 'scissors'];
var random = things[Math.floor(Math.random()*things.length)];
console.log('The computer chose: ' + random);
return random;
}
// plays a round of the game
function playRound(playerSelection, computerSelection){
if(playerSelection === computerSelection){
console.log("tie");
}
else if(playerSelection === "rock" && computerSelection === "paper"){
console.log("YOU LOSE");
computerWin();
}
else if(playerSelection === "rock" && computerSelection === "scissors"){
console.log("YOU WIN");
playerWin();
}
else if(playerSelection === "paper" && computerSelection === "rock"){
console.log("YOU WIN");
playerWin();
}
else if(playerSelection === "paper" && computerSelection === "scissors"){
console.log("YOU LOSE");
computerWin();
}
else if(playerSelection === "scissors" && computerSelection === "paper"){
console.log("YOU WIN");
playerWin();
}
else{
console.log("YOU LOSE");
computerWin();
}
}
function playerWin(){
++playerScore;
console.log("Player Score is " + playerScore);
}
function computerWin(){
++computerScore;
console.log("Computer Score is " + computerScore)
}
// Call functions
const playToScore = 3
while(playerScore !== playToScore && computerScore !== playToScore) {
let chooseWord = "Choose ";
let playerSelection = prompt(chooseWord);
console.log(playerSelection.toLowerCase());
let computerSelection = computerPlay();
computerSelection.toLowerCase();
playRound(playerSelection, computerSelection);
console.log('Results are: Player -', playerScore, 'Computer -', computerScore)
}
if (playerScore === playToScore) {
console.log('Player won with score', playerScore)
} else if (computerScore === playToScore) {
console.log('Computer won with score', computerScore)
}

The first function getComputerChoice() returns a random - rock, paper, or scissor. However, in the playRound function when the computer' choice and user's choice are compared, it shows incorrect answers for a few of them. For example, when I choose rock and computer chooses paper, I win, which is wrong.
I tried using if else and switch statements but faced the same problem. It would be great if someone could help me out.
let computerSelection = getComputerChoice();
let playerSelection = prompt("rock, paper, or scissor?").toLowerCase();
function getComputerChoice(){
const randomNumber = Math.floor(Math.random()*3);
if(randomNumber === 0){
choice = "rock";
} else if(randomNumber === 1){
choice = "paper";
} else if(randomNumber === 2){
choice = "scissor";
} return choice;
}
function playRound(playerSelection, computerSelection){
let result = '';
if(computerSelection === playerSelection){
result = "It's a tie";
} else if(computerSelection === 'paper' && playerSelection === 'rock'){
result = "you lose";
} else if(computerSelection === 'scissor' && playerSelection === 'rock'){
result = "you win";
} else if ((computerSelection === 'rock') && (playerSelection === 'paper')){
result = "You win";
} else if((computerSelection === 'scissor') && (playerSelection === 'paper')){
result = "you lose";
} else if ((computerSelection === 'paper') && (playerSelection === 'scissor') ){
result = "You win";
} else if((computerSelection === 'rock') && (playerSelection === 'scissor')){
result = "You lose";
}
return result;
};
alert("The computer chose: " + getComputerChoice());
alert("That means " + playRound(playerSelection, computerSelection));
In your first statement, you choose the computer selection. But in your second to last statement, you call getComputerChoice() which makes a DIFFERENT selection. Change the next to the last line to
alert("The computer chose: " + computerSelection);
Try adding this debug line that I have put in, and then look at the console in the browser. You will see what the computer really chose
function getComputerChoice(){
const randomNumber = Math.floor(Math.random()*3);
if(randomNumber === 0){
choice = "rock";
} else if(randomNumber === 1){
choice = "paper";
} else if(randomNumber === 2){
choice = "scissor";
}
// debug line
console.log('randomly chose', choice);
return choice;
}
ChatGPT?
This code will run but it has a couple of problems:
In the getComputerChoice function, the variable choice is declared without const, let, or var. This means that it's a global variable and could cause issues in the future.
The line alert("The computer chose: " + getComputerChoice()); is calling the getComputerChoice function twice, but it should only be called once and stored in the computerSelection variable.
The result of the playRound function is not being logged to the console or displayed in any other way, it's only being returned.
To resolve these problems, you could modify the code as follows:
let computerSelection = getComputerChoice();
let playerSelection = prompt("rock, paper, or scissor?").toLowerCase();
function getComputerChoice(){
let choice = '';
const randomNumber = Math.floor(Math.random() * 3);
if(randomNumber === 0){
choice = "rock";
} else if(randomNumber === 1){
choice = "paper";
} else if(randomNumber === 2){
choice = "scissor";
}
return choice;
}
function playRound(playerSelection, computerSelection){
let result = '';
if(computerSelection === playerSelection){
result = "It's a tie";
} else if(computerSelection === 'paper' && playerSelection === 'rock'){
result = "you lose";
} else if(computerSelection === 'scissor' && playerSelection === 'rock'){
result = "you win";
} else if ((computerSelection === 'rock') && (playerSelection === 'paper')){
result = "You win";
} else if((computerSelection === 'scissor') && (playerSelection === 'paper')){
result = "you lose";
} else if ((computerSelection === 'paper') && (playerSelection === 'scissor') ){
result = "You win";
} else if((computerSelection === 'rock') && (playerSelection === 'scissor')){
result = "You lose";
}
return result;
};
console.log("The computer chose: " + computerSelection);
console.log("That means " + playRound(playerSelection, computerSelection));
Your Code is not consistent : here is the answer:
let computerSelection = getComputerChoice();
let playerSelection = prompt("rock, paper, or scissor?").toLowerCase();
function getComputerChoice(){
const randomNumber = Math.floor(Math.random() * 3);
let choice;
if(randomNumber === 0){
choice = "rock";
} else if(randomNumber === 1){
choice = "paper";
} else if(randomNumber === 2){
choice = "scissors";
}
return choice;
}
function playRound(playerSelection, computerSelection){
let result = '';
if(computerSelection === playerSelection){
result = "It's a tie";
} else if(computerSelection === 'paper' && playerSelection === 'rock'){
result = "You lose";
} else if(computerSelection === 'scissors' && playerSelection === 'rock'){
result = "You win";
} else if ((computerSelection === 'rock') && (playerSelection === 'paper')){
result = "You win";
} else if((computerSelection === 'scissors') && (playerSelection === 'paper')){
result = "You lose";
} else if ((computerSelection === 'paper') && (playerSelection === 'scissors') ){
result = "You lose";
} else if((computerSelection === 'rock') && (playerSelection === 'scissors')){
result = "You win";
}
return result;
};
let result = playRound(playerSelection, computerSelection);
alert("The computer chose: " + computerSelection);
alert("That means " + result);
Note:
scissor has been corrected to scissors.
Consistent use of capitalization for "You win" and "You lose".
The result ofplayRound() function has been stored in a variable
result before using it in the alert
.
I am new to coding I have to do this rock paper scissors but can't find my error it still show me the else result each time.
Any help are welcome

Solution
You've missed the return keyword from the getUserChoice method.
function getUserChoice(){
return prompt("Please enter 'rock', 'paper', 'scissors': ").toLowerCase();
}
I'm trying to make a console version of rock paper scissors. The game is working for now but I can't run the for loop, what I want to do is at the end of each round, the console will say what round we are in and tell who won the current round. It will be the Best of 5 and the winner will be determined in round 5.
Since I'm a beginner I couldn't try too much. I know my code is not clean and complicated because I proceed by trying and I'm also new to Stackoverflow, if there is something missing in the topic, I apologize in advance for those.

You have to put the sections to get the player and computer choices inside the loop. I fixed some other problems, too.

You could move the playerSelection and computerSelection constants inside the playRound function. Then you can use the Window.confirm() method to show the results with a prompt to play again. If they select OK, then just call the playRound function again. If they click cancel then the game stops.
See snippet below.

Currently stuck with a rock, paper, scissors game in javascript. Only my last function game() which needs to play a round 5 times is not working. Have tried to work with a for loop but it seems that I'm getting 5 times the same answer instead of 5 different random ones.

You have put a loop without asking for the player and computer input, hence it runs 5 times without taking any input. I have fixed this in the snippet. Not entirely sure if you want to run it this way though.
let playerScore = 0;
let computerScore = 0;
// computer select function
function computerPlay() {
const option = ['rock', 'paper', 'scissors'];
let random = Math.floor(Math.random() * 3);
return option[random];
}
// player select function
function playerPlay() {
const input = prompt('Please enter input');
const option = input.toLowerCase();
return option;
}
// play 1 single round
function playRound(playerSelection, computerSelection) {
if (playerSelection === computerSelection) {
return 'It is a tie';
}
if (playerSelection === 'rock') {
if (computerSelection === 'scissors') {
playerScore++;
return 'Player wins with rock';
} else if (computerSelection === 'paper') {
computerScore++;
return 'Computer wins with paper'
}
}
if (playerSelection === 'paper') {
if (computerSelection === 'rock') {
playerScore++;
return 'Player wins with paper';
} else if (computerSelection === 'scissors') {
computerScore++;
return 'Computer wins with scissors';
}
}
if (playerSelection === 'scissors') {
if (computerSelection === "paper") {
playerScore++;
return 'Player wins with scissors';
} else if (computerSelection === 'rock') {
computerScore++;
return 'Computer wins with rock';
}
}
}
// console.log(playRound(playerSelection, computerSelection));
// game
function game() {
for (i = 0; i <= 5; i++) {
var playerSelection = playerPlay();
var computerSelection = computerPlay();
playRound(playerSelection, computerSelection);
console.log('Computer: ' + computerSelection);
console.log('Player: ' + playerSelection);

console.log('Computer: ' + computerScore);
}
console.log('Final Player: ' + playerScore);
console.log('Final Computer: ' + computerScore);
}

Your probleme is because you're set your playerSelection and computerSelection once (and even on a const ! So choice cannot be updated)
You just have to move this part into you for loop (and update to let instead of const)
let playerSelection = playerPlay();
let computerSelection = computerPlay();
let playerScore = 0;
let computerScore = 0;
// computer select function
function computerPlay() {
const option = ['rock', 'paper', 'scissors'];
let random = Math.floor(Math.random() * 3);
return option[random];
}
// player select function
function playerPlay() {
const input = prompt('Please enter input');
const option = input.toLowerCase();
return option;
}
// play 1 single round
function playRound(playerSelection, computerSelection) {
if(playerSelection === computerSelection) {
return 'It is a tie';
}
if(playerSelection === 'rock') {
if(computerSelection === 'scissors') {
playerScore++;
return 'Player wins with rock';
} else if(computerSelection === 'paper') {
computerScore++;
return 'Computer wins with paper'
}
}
if(playerSelection === 'paper') {
if(computerSelection === 'rock') {
playerScore++;
return 'Player wins with paper';
} else if(computerSelection === 'scissors') {
computerScore++;
return 'Computer wins with scissors';
}
}
if(playerSelection === 'scissors') {
if(computerSelection === "paper") {
playerScore++;
return 'Player wins with scissors';
} else if(computerSelection === 'rock') {
computerScore++;
return 'Computer wins with rock';
}
}
}
// game
function game() {
for(var i = 1; i <= 5; i++) {
let playerSelection = playerPlay();
let computerSelection = computerPlay();
console.log(`[Play turn ${i}] Player: ${playerSelection} | Computer: ${computerSelection}`);
playRound(i);
}
}
game();
Your code has a few issues.
You don't display output of next games. They are played but result is the same. It's same game configuration repeated 5 times.
console.log('repeat 5 times');
console.log(playRound(playerSelection, computerSelection));
Instead of:
console.log('repeat 5 times');
console.log(playRound(playerSelection, computerSelection));
You run functions playerSelection, computerSelection only once. So every next play has the same result.
You should execute these functions with every loop iteration.
Example:
let playerSelection = function () {
const input = prompt('Please enter input');
const option = input.toLowerCase();
return option;
};
let computerSelection = function () {
const option = ['rock', 'paper', 'scissors'];
let random = Math.floor(Math.random() * 3);
return option[random];
};
[...]
playRound(playerSelection(), computerSelection());
