How to cancel a subscribe?

[davidpkami]

I have been trying .Cancel() but is not working at all

PickUp1_Spawn.VehicleDestroyedEvent.Subscribe(StartCountdown_PickUp).Cancel()

You need to save the object returned by the subscribe and call cancel on that.

    # Implemented by classes that allow users to cancel an operation. For example, calling
    # `subscribable.Subscribe` with a callback returns a `cancelable` object. Calling `Cancel`
    # on the return object unsubscribes the callback.
    cancelable<native><public> := interface:
        # Prevents any current or future work from completing.
        Cancel<public>()<transacts>:void

Adding solution with @Megaspace code

var OurCancelable:?cancelable = false
OnBegin=
  L_Cancelable:cancelable = PickUp1_Spawn.VehicleDestroyedEvent.Subscribe(StartCountdown_PickUp) 
  set OurCancelable = option{L_Cancelable}

SomeCancelFunction():void=
  if (Subscription := OurCancelable?):
    Subscription.Cancel()
