Struct veloren_world::site::settlement::Land

pub struct Land {
    tiles: HashMap<Vec2<i32>, Tile, BuildHasherDefault<FxHasher64>>,

Fields

tiles: HashMap<Vec2<i32>, Tile, BuildHasherDefault<FxHasher64>>

We use this hasher (FxHasher64) because (1) we need determinism across computers (ruling out AAHash); (2) we don’t care about DDOS attacks (ruling out SipHash); (3) we have 8-byte keys (for which FxHash is fastest).

plots: Store<Plot>

sampler_warp: StructureGen2d

hazard: Id<Plot>
