Computer Wins Everytime in Rock Paper Scissor Game

February 11, 2024

Hello so I have created a simple rock paper scissor game using Kotlin. But the computer seems to win everytime even though I had won technically. Please have a look at my code and help me. Thanks `package com.blinky.kotlinbasics

fun main() {
    val computerChoice = ""
    var playerChoice = ""
    println("Rock, Paper or Scissor? Enter your choice!")
    playerChoice = readln()

    val randomNumber = (1..3).random()
    if(randomNumber == 1){
    println("Rock")
}
else if(randomNumber == 2){
    println("Paper")
}
else if(randomNumber == 3){
    println("Scissor")
}

    val winner = when{
    playerChoice == computerChoice -> "Tie"
    playerChoice == "Rock" && computerChoice == "Scissor" -> "Player"
    playerChoice == "Paper" && computerChoice == "Rock" -> "Player"
    playerChoice == "Scissor" && computerChoice == "Paper" -> "Player"
    else -> "Computer"
}
if(winner == "Tie"){
    println("The game is a tie")
}
else{
    println(winner + " won!")
}

}

>Solution :

The computers choice is never saved, it is only printed. So instead of only printing the computers choice, you might want to modify one part of your code to:

if(randomNumber == 1){
    println("Rock")
    computerChoice = "Rock"
}
else if(randomNumber == 2){
    println("Paper")
    computerChoice = "Paper"
}
else if(randomNumber == 3){
    println("Scissor")
    computerChoice = "Scissor"
}
