SummonList myList; // Add a new object to the list myList.AddNewObject(...); // Remove the object from the list myList.Despawn(objectToRemove);In this example, we create a new SummonList called `myList`. We then add a new object to the list using the `AddNewObject` method (not shown). Finally, we remove the object from the list using the `Despawn` method and passing in the object we want to remove as a parameter. It is difficult to determine the package library without more information about the code surrounding SummonList. However, it is possible that SummonList is part of a larger game engine or game development library.
