I want to add a simple timer. Something like this

var breakTime = 3
        var breakTimeText = text("Starting game in $breakTime seconds") {
            position(10, 500)
            addUpdater {
                Count down to 0 in 1 sec intervals
                update breakTime on each interval
                if 0, then call function breakOver

            }
        }

i want the counter to go down to zero and then call a function. any tips on how I can achieve that?

One of the ways:

var breakTime = 3
val breakTimeText = text("Starting game in $breakTime seconds").position(10, 500)
launchImmediately {
	while (breakTime > 0) {
		println(breakTime)
		breakTimeText.text = "Starting game in $breakTime seconds"
		delay(1.seconds)
		breakTime--
	}
    callFunction()
}

Is there a variant which can work from within the addUpdater or at every tick?
What I want to do is to check the current game state at every tick. If the state = something, then after n seconds update the state to something else.
Trying this code within addUpdater throws Suspension functions can be called only within coroutine body

You can get the same result with a simpler approach. When you change your state to 'something', you need to call a function that will start the count down.

So you won't need to add additional check that runs every tick. You just call the action right when the state is changed.

The it in addUpdater has the timespan which passed since the last frame if that helps.
