How do I unsubscribe from an event on a specific element?
Right now I have subscribed to the control change event of a capture area. Later I want to reset that capture area so it can be captured by the same team again, but when I reset the capture area it calls the subscribed event, which throughs everything into disarray. If I can just cancel the subscription between capturing and resetting the capture area everything should work.
When you call Subscribe on any device events they will return a cancelable which you can subsequently call Cancel() on to terminate the subscription.
hello_world_device := class(creative_device):
@editable CaptureArea:capture_area_device = capture_area_device{}
var ControlChangeSubscription:?cancelable = false
OnBegin<override>()<suspends>:void=
set ControlChangeSubscription = option{ CaptureArea.ControlChangeEvent.Subscribe(HandleControlChange) }
# Do whatever logic you like then cancel
if (Subscription := ControlChangeSubscription?):
Subscription.Cancel()
The EliminatedEvent is a function so you would need to write EliminatedEvent().Subscribe(....
Depending on how/where you call things and what exact type you need to return you might need to do something like this
Temp:cancelable = Character.EliminatedEvent().Subscribe(KingEliminated)
set KingSubscription = option{Temp}
to satisfy every language requirement.
