Parallel Universe: Difference between revisions

[[File:ParallelUniverseViews.jpg|thumb|A diagram of Parallel Universe movement in [[Hazy Maze Cave]], after [[Mario]] has returned to the main map.]]A '''Parallel Universe''', or '''PU''', is an area in a ''[[Super Mario 64]]'' map at which the game creates phantom floors, walls, or ceilings despite [[Mario]] being "outside" of the level. This is because the casted position value used to check for ground below Mario doesn't have enough bits to go above 7FFF_h or below -8000_h, unlike Mario's actual position, which is a [[float]].[[File:Visible PU.png|thumb|184x184px|Frame of [[Peter Fedak|Peter Fedak's]] video where he turns Parallel Universes visible using hacks; notice the lack of [[objects]]|left]] Though usually the term "PU" refers to a horizontal PU (i.e. one caused by truncation of Mario's X and/or Z positions), vertical PUs (where the Y coordinate is truncated) also exist. However, since Mario's Y position cannot exceed 20000 in most circumstances, there are only three ways to reach a positive vertical PU: Hyper Speed Flying, Platform Release Displacement, and Indefinite Owl Flight. Negative vertical PUs can be reached with Hyper Speed Flying, Platform Release Displacement, or an Overflow Jump. Since all object positions are floats, there are no [[objects]] in PUs unless Mario brings one there.
