Trait TileMetadata 

pub trait TileMetadata<T: TileMetaTrait> {
    // Required methods
    fn is_passable(&self, tileset: T, tile_id: u8) -> bool;
    fn collision_type(&self, tileset: T, tile_id: u8) -> CollisionType;
    fn is_ledge(&self, tileset: T, tile_id: u8) -> bool;
    fn is_counter(&self, tileset: T, tile_id: u8) -> bool;
    fn is_grass(&self, tileset: T, tile_id: u8) -> bool;
    fn get_grass_tile(&self, tileset: T) -> Option<u8>;
}

Provides collision and terrain metadata for tiles in a given tileset.

The engine queries this trait whenever an entity attempts to move onto a tile, to determine whether the movement is valid and what special behaviour (if any) should trigger.

Required Methods

fn is_passable(&self, tileset: T, tile_id: u8) -> bool

Returns true if a tile with the given ID in the given tileset can be walked on freely.

fn collision_type(&self, tileset: T, tile_id: u8) -> CollisionType

Returns the full CollisionType for a tile.

fn is_ledge(&self, tileset: T, tile_id: u8) -> bool

Returns true if the tile is a ledge.

fn is_counter(&self, tileset: T, tile_id: u8) -> bool

Returns true if the tile is a counter.

fn is_grass(&self, tileset: T, tile_id: u8) -> bool

Returns true if the tile is tall grass.

fn get_grass_tile(&self, tileset: T) -> Option<u8>

Returns the special grass tile ID for encounter calculations, or None if the default encounter rate should be used.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
