Hello im making a game were if i use a card a human summons on an island and i also have a card that removes humans but how do i only remove one clone??
You have to keep a reference to the instantiated object somewhere.
You can use a dynamic set you containing your instantiated object (such as a List). Depending on how the objects must be destroyed, you may be interested by the Stack (last one added is the first one deleted) or the Queue (first one added is the first one deleted).
