Bool property to show/do things once

[antstubell]

Rusty at scripting and I've forgot how to do this. Make the script below show the notification once using a bool property. I know I can use global variables but this seems wasteful for just one instance and I don't want a load of variables just for this purpose.

Thank you.

 

Event OnContainerChanged(ObjectReference akNewContainer, ObjectReference akOldContainer)

if akOldContainer && !akNewContainer
Debug.Notification("I’ve have been dropped and will disappear.")
Self.Delete()

EndIf
EndEvent

This uses a local bool variable rather than a property, but can be changed to a property if needed.

 

Bool DoOnce = false

Event OnContainerChanged(ObjectReference akNewContainer, ObjectReference akOldContainer)
  If (DoOnce == false) && (akOldContainer && !akNewContainer)
    Debug.Notification("I’ve have been dropped and will disappear.")
    Self.Delete()
    DoOnce = true
  EndIf
EndEvent

 

 

If this were a more often ran event, you could use the state approach and change states such that nothing will be done when the event is triggered.

Thanks. I need the dropped item to be deleted every time but see the massage once. I'm guessing swapping the lines DoOnce = true and Self.Delete() will achieve this?

Helps to know intent...

 

This should do what you want

 

 

Bool DoOnce = false

Event OnContainerChanged(ObjectReference akNewContainer, ObjectReference akOldContainer)
  If (akOldContainer && !akNewContainer)
    If (DoOnce == false)
      Debug.Notification("I’ve have been dropped and will disappear.")
      DoOnce = true
    EndIf
    Self.Delete()
  EndIf
EndEvent
