Struct Instance

pub struct Instance {
    pub chunks: ChunkStorage,
    pub entities_by_chunk: HashMap<ChunkPos, HashSet<Entity>>,
    pub entity_by_id: IntMap<MinecraftEntityId, Entity>,
    pub registries: RegistryHolder,
}

A world where the chunks are stored as weak pointers. This is used for shared worlds.

Fields

chunks: ChunkStorage

entities_by_chunk: HashMap<ChunkPos, HashSet<Entity>>

An index of all the entities we know are in the chunks of the world

entity_by_id: IntMap<MinecraftEntityId, Entity>

An index of Minecraft entity IDs to Azalea ECS entities.

You should avoid using this (particularly if you’re using swarms) and instead use azalea_entity::EntityIdIndex, since some servers may give different entity IDs for the same entities to different players.

registries: RegistryHolder

Implementations

impl Instance

pub fn find_block( &self, nearest_to: impl Into<BlockPos>, block_states: &BlockStates, ) -> Option<BlockPos>

Find the coordinates of a block in the world.

Note that this is sorted by x+y+z and not x^2+y^2+z^2 for optimization purposes.

client.world().read().find_block(client.position(), &azalea_registry::Block::Chest.into());

pub fn find_blocks<'a>( &'a self, nearest_to: impl Into<BlockPos>, block_states: &'a BlockStates, ) -> FindBlocks<'a>

Find all the coordinates of a block in the world.

This returns an iterator that yields the BlockPoss of blocks that are in the given block states. It’s sorted by x+y+z.

impl Instance

pub fn get_block_state(&self, pos: &BlockPos) -> Option<BlockState>

pub fn get_fluid_state(&self, pos: &BlockPos) -> Option<FluidState>

pub fn set_block_state( &self, pos: &BlockPos, state: BlockState, ) -> Option<BlockState>

Trait Implementations

impl Debug for Instance

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

Formats the value using the given formatter.

impl Default for Instance

fn default() -> Instance

Returns the “default value” for a type.

impl From<ChunkStorage> for Instance

fn from(chunks: ChunkStorage) -> Self

Make an empty world from this ChunkStorage. This is meant to be a convenience function for tests.
