I’ve been trying to solve the Rock, Paper and Scissors project but I can’t figure out how to make the if/else statement. I did it a lot of times and finally I think I’m near to solve the issue, but the thing is, every time I run the program I get the wrong output.
For example, I used ‘Paper’ and the computer used ‘Rock’, but the console showed that ‘It’s a tie’, but in the code I wrote that if player chose paper and computer chose rock the message should have been ‘You win. Paper beats Rock’. The same happens when I choose ‘Paper’ and the computer chooses ‘Scissors’.
I used toLowerCase() method but after many changes, even when remove it and write exactly the words in the if/else this does not appear to be the problem.
What do I need to correct? Thank you so much!!!
This is the code:
<!DOCTYPE html>
<html>
<head>
<title>Rock Paper Scissors!</title>
</head>
<body>
<script>
//Computer's selection
function computerPlay(){
let selectRandom = Math.floor(Math.random()*3);
if(selectRandom === 0){
return 'Rock';
}else if (selectRandom === 1){
return 'Paper';
}else{
return 'Scissors';
}
}
console.log('Computer chose: '+ computerPlay());
//Play round between humand and computer
function playRound(playerSelection, computerSelection) {
//Change to lowercase
let player = playerSelection.toLowerCase();
let computer = computerSelection.toLowerCase();
//If player chooses rock
if (player === 'rock'){
if(computer === 'rock'){return 'It\'s a tie. Try again'}
else if(computer === 'paper'){return 'You loose. Paper beats Rock'}
else{return 'You win. Rock beats scissors'}
}
//If player chooses paper
else if (player === 'paper'){
if(computer === 'paper'){return 'It\'s a tie. Try again'}
if(computer === 'scissors'){return 'You loose. Scissors beats Paper'}
else{return 'You win. Paper beats Rock'}
}
//If player chooses scissors
else{
if(computer === 'scissors'){return 'It\'s a tie. Try again'}
else if(computer === 'rock'){return 'You loose. Rock beats Scissors'}
else{return 'You win. Scissors beats Paper'}
}
}
const playerSelection = 'Paper';
const computerSelection = computerPlay();
console.log(playRound(playerSelection, computerSelection));
</script>
