Hi All!

Hope you're all doing well :)

Its been a few weeks longer than it should have been but work... kids.. pets...

I'd love some feedback on my attempt at Rock, Paper, Scissors..

I have jazzed it a bit by starting at 10 points and slowly decreasing the points you can get with a timer, when the timer hits 0 you loose that round and another starts - if you get it wrong you loose 5 points, if you are very quick and correct you could win 10 points!

As always feedback is very appreciated! (I know that I have just ripped off the radialgradient from the flag game :)

Hi!

Nice approach on completing the challenge! I have a question, where do you handle the case that the user picks the same ? My logic func is as per attached below :

func checkAnswer(answer: Int) {
        questionCount += 1
        let winOrLoseCheck = shouldWin
        var scoreAmend = 0
        if winOrLoseCheck {
            scoreAmend += 1
        } else {
            scoreAmend -= 1
        }
       let oldScore = yourScore

        if moves[moveNumber] == "🪨" && winningMoves[answer] == "📃" {
            yourScore += scoreAmend
        } else if moves[moveNumber] == "🪨" && winningMoves[answer] == "✂️" {
            yourScore -= scoreAmend
        } else if moves[moveNumber] == "🪨" && winningMoves[answer] == "🪨" {
            yourScore += 0
        } else if moves[moveNumber] == "📃" && winningMoves[answer] == "✂️" {
            yourScore += scoreAmend
        } else if moves[moveNumber] == "📃" && winningMoves[answer] == "🪨" {
            yourScore -= scoreAmend
        } else if moves[moveNumber] == "📃" && winningMoves[answer] == "📃" {
            yourScore += 0
        } else if moves[moveNumber] == "✂️" && winningMoves[answer] == "🪨" {
            yourScore += scoreAmend
        } else if moves[moveNumber] == "✂️" && winningMoves[answer] == "📃" {
            yourScore -= scoreAmend
        } else if moves[moveNumber] == "✂️" && winningMoves[answer] == "✂️" {
            yourScore += 0
        }

        //Was the Answer correct or not.
        if oldScore < yourScore {
            wasCorrectAnswer = true
        } else {
            wasCorrectAnswer = false
        }
        showRectangle = false
        newGame()
    }
