Struct VoxelWorldQuery 

pub struct VoxelWorldQuery<'w, 's, 'a, Q, F>
where
    Q: WorldQuery + 'static,
    F: ReadOnlyWorldQuery + 'static,
{ /* private fields */ }

A readonly utility handler for querying chunks within a specific voxel world.

Implementations

impl<'w, 's, 'a, Q, F> VoxelWorldQuery<'w, 's, 'a, Q, F>

where Q: WorldQuery + 'static, F: ReadOnlyWorldQuery + 'static,

pub fn iter( &'a self, ) -> impl Iterator<Item = <<Q as WorldQuery>::ReadOnly as WorldQuery>::Item<'a>> + 'a

Creates a readonly iterator over all chunks within this world that match the query.

This method is implemented by applying a filter the top of the standard query iterator. As such, calling them method for multiple worlds might be slower than calling VoxelQuery::iter directly.

pub fn get_chunk( &'a self, chunk_coords: IVec3, ) -> Option<<<Q as WorldQuery>::ReadOnly as WorldQuery>::Item<'a>>

Gets the chunk at the given chunk coordinates within this world, if it is both loaded and matches the indicated system query. Otherwise, this method returns None.

pub fn get_chunk_at_block( &'a mut self, block_coords: IVec3, ) -> Option<<<Q as WorldQuery>::ReadOnly as WorldQuery>::Item<'a>>

Gets the chunk at the given block coordinates within this world, if it is both loaded and matches the indicated system query. Otherwise,

pub fn world_id(&self) -> Entity

Gets the id of the voxel world being handled.
