Create game over scene if button is not pressed in time (in swift)

🎤 General Discussion Swift

My code is a streetlight that goes from red → yellow → green and times your reaction time when the light goes green. I want the user to switch view controllers to the game over view controller (automatically) if the user does not press the button within 3 seconds. I know how to segue the view controller so I don’t need the code to that. I just need to know how to do a nested if loop within the update counter function. So that the user can either play the game again on go to the game over scene. If else options depending on weather the users reaction time was las than< 3 than seconds or greater than or equal to 3 seconds.

      var timer = Timer()
 var scoreTimer = Timer()

var timerInt = 0
var scoreInt = 0


override func viewDidLoad() {
super.viewDidLoad()
scoreInt = 0
labzel.text = String(scoreInt)
}

@IBAction func hitTheButton(_ sender: AnyObject) {


if scoreInt == 0{
    timerInt = 3
    light.image = UIImage(named: "r.png")
    timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(ViewController.updateCounter), userInfo: nil, repeats: true)

    startStop.isEnabled = false
    startStop.setTitle("Restart", for: [])


    scoreInt = 0
    labzel.text = String(scoreInt)


} else {
    scoreTimer.invalidate()

}

if timerInt == 0 {
    scoreInt = 0
    startStop.setTitle("Restart", for: [])


}}
// This is where the game is counted down from red to yellow to green.
func updateCounter(){

timerInt -= 1
if timerInt == 2{
    light.image = UIImage(named: "r.png")
} else if timerInt == 1 {
    light.image = UIImage(named: "yellow.png")
} else if timerInt == 0 {
    light.image = UIImage(named: "g.png")



        timer.invalidate()
        startStop.isEnabled = true
        scoreTimer = Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(ViewController.updateScoreTime), userInfo: nil, repeats: true)


}}
func updateScoreTime(){
scoreInt += 1
labzel.text = String(scoreInt)

 }}

Hi @zalubski,
Have you tired to have a flag that contains when the button was pressed, say with a default value of 0. When the button is pressed, set this to the currentTime (so a non zero value will indicate a button pressed state) and go to button pressed, stop timer and go to the Score_Page. Have a timer that changes the traffic light colors and when the timer finishes then goto the Score_Page.

On the Score_Page routine, check if the button was pressed or not and then also check if the button was pressed pre-maturely or not.

cheers,
