Hi, @BrendannnD

What about adding the effect suspends ?

I need to use .await inside the “MainFunction”. Because I need to use a Countdown. Followed the tutorial for this

So I added but I end up with an error, that idk how to resolve. In line:

Zone.AreaIsScoredEvent.Subscribe(HandlerAreaIsScoredEvent{Device:=Self, Zone:=I}.HandlerFunction)

My code


var CountdownTimer : countdown_timer = countdown_timer{}
InitialCountdownTime : float = 30.0  

HandlerAreaIsScoredEvent:= class() {
    Device : Conquest   
    Zone : int  

    HandlerFunction(Agent : agent)<suspends> : void = {
        Device.MainFunction(Agent, Zone)
    }
}

OnBegin<override>()<suspends>:void=
  for( I->Zone: Zones):
    Zone.AreaIsScoredEvent.Subscribe(HandlerAreaIsScoredEvent{Device:=Self, Zone:=I}.HandlerFunction)

MainFunction(Agent: agent, Zone : int)<suspends> : void = {
  StartCountdown()

StartCountdown()<suspends>: void =
  Print("Starting countdown")
        
  AllPlayers:[]player = GetPlayspace().GetPlayers()
    for(Player:AllPlayers):
      if(PlayerUI := GetPlayerUI[Player]):
        set CountdownTimer = countdown_timer{MaybePlayerUI := option{PlayerUI}, RemainingTime := InitialCountdownTime}
        CountdownTimer.StartCountdown()
        CountdownTimer.CountdownEndedEvent.Await()
