Struct Tilemap 

pub struct Tilemap {
    pub width: u16,
    pub height: u16,
    pub entries: Vec<TilemapEntry>,
}

A two-dimensional tilemap using TilemapEntry instead of raw byte indices.

Unlike the classic GB TileMap (a flat Vec<u8> of tile indices), this tilemap carries per-tile metadata and supports arbitrary widths and heights.

Fields

width: u16

Number of tiles horizontally.

height: u16

Number of tiles vertically.

entries: Vec<TilemapEntry>

Row-major tile entries. entries[y * width as usize + x].

Implementations

impl Tilemap

pub fn new(width: u16, height: u16) -> Self

Creates a new tilemap filled with default entries (tile_id = 0, no flips, no collision/animation overrides).

Panics

Panics if width or height is 0.

pub fn from_gb_tilemap(data: &[u8], width: u16, height: u16) -> Self

Converts a classic Game Boy tilemap (flat &[u8] of tile indices) into a Tilemap of TilemapEntrys.

Each byte in data becomes a TilemapEntry with that byte as tile_id and all other fields set to their defaults.

Panics

Panics if data.len() is less than width * height.

pub fn in_bounds(&self, x: u16, y: u16) -> bool

Returns true if (x, y) is within bounds.

pub fn get(&self, x: u16, y: u16) -> Option<&TilemapEntry>

Returns a reference to the tile entry at (x, y), or None if out of bounds.

pub fn get_mut(&mut self, x: u16, y: u16) -> Option<&mut TilemapEntry>

Returns a mutable reference to the tile entry at (x, y), or None if out of bounds.

pub fn set(&mut self, x: u16, y: u16, entry: TilemapEntry)

Sets the tile entry at (x, y). Silently does nothing if out of bounds.

pub fn fill_rect(&mut self, x: u16, y: u16, w: u16, h: u16, entry: TilemapEntry)

Fills a rectangular region with copies of entry.

Coordinates are clamped to the tilemap bounds; no-op if the region lies entirely outside.

Trait Implementations

impl Clone for Tilemap

fn clone(&self) -> Tilemap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Tilemap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
