Out of bounds: Difference between revisions

Since byte operations overflow and underflow normally, the left side and right side are "connected together", and so isare the top side and the bottom side, although the player cannot directly step through the boundary without triggering a (possibly invalid) map connection.

* X = map-1 width(0xFF);

* YX = -1map (0xFF)width;

* Y = map-1 height.(0xFF);

(Instead of walking through walls, the player can also use a tile corruption glitch to remove the "wall" tiles, for example with [[dokokashira door glitch]] or [[Super Glitch]]. Or they can take a wrong warp to a normally inaccessible area, etc.) <!-- Is it possible to take a wrong warp directly to an OOB area (without ACE)? -->

Another way to go out of bounds is to '''directly change the player's coordinate''', for example with an [[expanded items pack]], throughby taking a wrong warp (e.g. through the [[GlitchSafari CityZone (Red/Blue/Yellow)|Glitchexit Cityglitch]]), or using [[arbitrary code execution]].

The properties of the base map in out of bound areas is related to the "tile block map". To save on space, the map data in the ROM is actually not stored as tiles, but as "tile blocks", which are 2*2 blockblocks of tiles. Each tile block is represented by a single byte, whichand they are translated into tiles only when they are displayed on screen. The translation rules depend on the current tileset.

The tile block map must be loaded into the RAM, because it may be changed by the player cutting down trees. Furthermore, there is a 3 block "padding" in each direction, so that the player doesn't see invalid data when they stand near the boundary of the in bound area. If the there are any map connections, the "preview" of connecting maps are also loaded into the tile block map. Therefore, each row in the tile block map consists of (w/2 + 6) bytes, where w is the width of the map in tiles.

# With a walk through walls cheat code enabled, go inside of the Contest Building in Lilycove City.

# Talk to the leftmost attendant either directly facing her, from the left, or from behind and enter a contest.

# The player will then walk into the black void behind the door, but unlike both previous generations, nothing will happen.

# After the player passes through the dialog, they will enter the contest normally.

In {{SM}}, it is possible to go out of bounds in a Pokémon Center with the [[delivery man out of bounds glitch]], but it is not possible to enter other maps. It is also possible to clip through some NPCs in several areas of the game and go out of bounds, however you cannot save your game once in this position.
