Struct TerrainRenderer 

pub struct TerrainRenderer {
    pub pos_to_tile: HashMap<ChunkPos, usize>,
    pub tiles: Vec<TerrainRenderTile>,
    pub dirty: Vec<Option<(ChunkPos, u32, u32, Vec<u8>)>>,
}

Holds the tiles used for rendering. Note that all tiles are not necessarily rendered.

Fields

pos_to_tile: HashMap<ChunkPos, usize>

Pointer from tile position (x, z) to the corresponding tile datas

tiles: Vec<TerrainRenderTile>

A list of terrain render tiles that make up the entire terrain.

dirty: Vec<Option<(ChunkPos, u32, u32, Vec<u8>)>>

Implementations

impl TerrainRenderer

pub fn new(asset_server: &AssetServer) -> Self

Initializes the terrain renderer by creating the heightmap and splat map textures for each tile, and setting up the mapping from tile positions to their corresponding data.

Arguments

• asset_server - The Bevy asset server used to create the texture assets for the heightmaps and splat maps.

Returns

A TerrainRenderer component containing the initialized terrain render tiles with their respective heightmap and splat map textures, as well as the mapping from tile positions to their data.

pub fn extract_dirty( renderer: Query<'_, '_, &mut TerrainRenderer>, terrain: Query<'_, '_, &mut Terrain>, )

Extracts the dirty tiles from the main terrain

Trait Implementations

impl Component for TerrainRenderer

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = ::bevy::ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have [Component<Mutability = Mutable>], while immutable components will instead have [Component<Mutability = Immutable>].

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns [ComponentRelationshipAccessor] required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add [ComponentHook] for this [Component] if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert [ComponentHook] for this [Component] if one is defined.

fn on_replace() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_replace [ComponentHook] for this [Component] if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove [ComponentHook] for this [Component] if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn [ComponentHook] for this [Component] if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given [EntityMapper]. This is used to remap entities in contexts like scenes and entity cloning. When deriving [Component], this is populated by annotating fields containing entities with #[entities]
