Map documentation
This section of the documentation aims to provide an overview of the different map-related subsystems, the interaction between them, and how they load their data from the ROM so that, in the end, the game can seamlessly render a world in which the player moves.
Glossary
- Area: a collection of maps that load the same set of textures and map prop models.
- BDHC: contains data used to calculate the height of the terrain. Used for collision detection and the map objects height, for example.
- Map: a 2D grid of 32x32 tiles that form part of the game's world.
- Map header: a structure that contains metadata about a map, such as its music, its name, whether cycling is allowed, etc. Each map is associated with a map header, and has a specific, well-known ID.
- Map matrix: a 2D array of maps that form a playable area. This system allows the game to dynamically load and unload maps as the player moves around the world. The overworld is one such example of a map matrix, containing 30x30 maps.
- Map object: an entity that is placed on the map. Examples include the player and NPCs.
- Map prop: a 3D model that is placed on the map. Examples include the various buildings encountered throughout the game, but also interior furniture, honey trees, etc.
- NARC: Nitro ARChive, a file format used by Nintendo DS games to store files.
(think archive as in a
.tarfile, a file that contains files) - NSBCA/NSBTP/NSBTA: file formats used to store animations for 3D models for the Nintendo DS. See apicula's documentation for more information.
- NSBMD: a file format used to store 3D models, textures and palettes for the Nintendo DS. See apicula's documentation for more information.
- NSBTX: a file format used to store textures and palettes for the Nintendo DS. See apicula's documentation for more information.
