}Expand description
Trait for allowing function to work on both World and SubWorld
Required methods
fn try_query<Q: Query + Subset>(&self) -> Result<QueryBorrow<'_, Q>>
fn try_query<Q: Query + Subset>(&self) -> Result<QueryBorrow<'_, Q>>
Queries the world
Queries the world for a specific entity
Get a single component for an entity Returns the contextual result since hecs-schedule is required to be imported anyway
fn try_get_mut<C: Component>(&self, entity: Entity) -> Result<RefMut<'_, C>>
fn try_get_mut<C: Component>(&self, entity: Entity) -> Result<RefMut<'_, C>>
Get a single component for an entity Returns the contextual result since hecs-schedule is required to be imported anyway
fn try_get_column<C: Component>(&self) -> Result<Column<'_, C>>
fn try_get_column<C: Component>(&self) -> Result<Column<'_, C>>
Borrow every component of type C
fn try_get_column_mut<C: Component>(&self) -> Result<ColumnMut<'_, C>>
fn try_get_column_mut<C: Component>(&self) -> Result<ColumnMut<'_, C>>
Borrow every component mutably of type C
