Private Methods

Méthode	Description
AddGameObject ( ScrollingShooter.GameObject gameObject ) : void	Helper method that adds a GameObject to the GameObjectManager
InsertBoundIntoAxis ( List axis, Bound bound ) : int	Inserts a new bound into an axis list. The list is assumed to be sorted, so the method uses binary insertion for speed.
NextID ( ) : uint	Helper method that provides the next unique game object ID
QueueGameObjectForCreation ( ScrollingShooter.GameObject go ) : void	Helper method for enqueueing our game object for creation at the start of the next update cycle.
RemoveGameObject ( ScrollingShooter.GameObject gameObject ) : void	Removes a Game object from the axis
UpdateAxisLists ( ) : void	Sorts the axis using insertion sort - provided the list is already nearly sorted, this should happen very quickly
