'Scenegraph' is also one of the components found on the scene controller object.
It manages scene zone objects that can be placed all over the scenes.
Also, 'Scenegraph' uses scene zones to activate / deactivate objects assigned to them depending on where a player is to reduce performance impact.
Usage:
To create scene zones, create an object with collider and add 'SceneZone' component on it.
Next, add game objects that you wish this scene zone
control. That is, to deactivate/activate depending if a player isin the zone or in one of connecting zones.
And last, add scene zones that are connected to this scene zone. That means that objects in those scene zones will not be deactivated.
Note that objects get deactivated only when a player enters a new zone and not when he leaves the current zone.
