Editing Stage

A '''stage''' or '''scene''' refers to one contiguous area in space in the game. On a technical level, a stage generally refers to a file containing a collection of objects and models that should exist within the same contiguous space, while a scene refers to the space containing the objects after they are loaded into memory. However, in most cases, the terms are used interchangeably.

== Explanation ==
Although each level generally takes place within its own stage, there are a handful of stages that contain two or more separate areas that give the illusion of being disjointed. This illusion is generally maintained by keeping the levels very far away from each other, and [[unloading]] the objects in one level if they would otherwise be visible from the other level. These examples are as follows:
* The main area of the [[Metro Kingdom]] and the [[New Donk City Hall Auditorium]] sub-world
* The main area of the [[Luncheon Kingdom]] and the [[Cascading Magma]] sub-world
* [[Shiveria Town]] in the [[Snow Kingdom]] and each of the four rooms containing [[Story moon|story moons]]
* The entrance area to the [[Underground Power Plant]] in the [[Metro Kingdom]] and the corresponding platforming room
In some cases, this practice makes it possible to travel from one such level to another in the same stage using glitches such as the [[suckage glitch]], rather than going through the intended [[loading zone]] or [[pipe]].

== Properties ==
Moving Mario between areas within the same scene is much faster than loading a completely new scene. This is immediately obvious when entering one of these areas, since the loading time will be almost instantaneous.

Changes to an area that have scene-level [[persistence]] will not be reverted when the player moves between areas in the same scene.

It is thought that the reason these areas are stored in the same scene is to allow cutscenes to be played across different areas without the need to load a new scene. For example:
* Obtaining a [[story moon]] from a musician in the [[Metro Kingdom]] will transfer Mario to the interior of the [[New Donk City Hall Auditorium]]. Storing the auditorium's interior in the same scene removes the loading time from this transfer.
* After collecting the ''Climb Up the Cascading Magma'' story moon in the [[Luncheon Kingdom]], the game plays a cutscene that takes place in the main area of the kingdom. If the areas were stored in separate scenes, the game would need to switch between these areas to play the cutscene, which would introduce two loading periods.
* After collecting a story moon from one of the four rooms branching out from [[Shiveria Town]], the game plays a cutscene that takes place in the main Shiveria Town room. If the areas were stored in separate scenes, the game would need to switch between these areas to play the cutscene.
* The reasoning for the two rooms of the [[Underground Power Plant]] being in the same scene is not as clear, but it may be to prevent players from accidentally undoing their progress killing the [[Big Poison Piranha Plant|Big Poison Piranha Plants]] at the end by going back through the pipe.
