Defines the World and APIs for accessing it directly.

Re-exports

• pub use crate::change_detection::Mut;
• pub use crate::change_detection::Ref;
• pub use crate::change_detection::CHECK_TICK_THRESHOLD;

Modules

• error
  Contains error types returned by bevy’s schedule.
• reflectbevy_reflect
  Provides additional functionality for World when the bevy_reflect feature is enabled.
• unsafe_world_cell
  Contains types that allow disjoint mutable access to a World.

Structs

• CommandQueue
  Densely and efficiently stores a queue of heterogenous types implementing Command.
• DeferredWorld
  A World reference that disallows structural ECS changes. This includes initializing resources, registering components or spawning entities.
• EntityMut
  Provides mutable access to a single entity and all of its components.
• EntityMutExcept
  Provides mutable access to all components of an entity, with the exception of an explicit set.
• EntityRef
  A read-only reference to a particular Entity and all of its components.
• EntityRefExcept
  Provides read-only access to a single entity and all its components, save for an explicitly-enumerated set.
• EntityWorldMut
  A mutable reference to a particular Entity, and the entire world.
• FilteredEntityMut
  Provides mutable access to a single entity and some of its components defined by the contained Access.
• FilteredEntityRef
  Provides read-only access to a single entity and some of its components defined by the contained Access.
• FilteredResources
  Provides read-only access to a set of Resources defined by the contained Access.
• FilteredResourcesBuilder
  Builder struct to define the access for a FilteredResources.
• FilteredResourcesMut
  Provides mutable access to a set of Resources defined by the contained Access.
• FilteredResourcesMutBuilder
  Builder struct to define the access for a FilteredResourcesMut.
• OccupiedEntry
  A view into an occupied entry in a EntityWorldMut. It is part of the Entry enum.
• OnAdd
  Trigger emitted when a component is added to an entity. See crate::component::ComponentHooks::on_add for more information.
• OnInsert
  Trigger emitted when a component is inserted onto an entity. See crate::component::ComponentHooks::on_insert for more information.
• OnRemove
  Trigger emitted when a component is removed from an entity. See crate::component::ComponentHooks::on_remove for more information.
• OnReplace
  Trigger emitted when a component is replaced on an entity. See crate::component::ComponentHooks::on_replace for more information.
• SpawnBatchIter
  An iterator that spawns a series of entities and returns the ID of each spawned entity.
• VacantEntry
  A view into a vacant entry in a EntityWorldMut. It is part of the Entry enum.
• World
  Stores and exposes operations on entities, components, resources, and their associated metadata.
• WorldId
  A unique identifier for a World.

Enums

• Entry
  A view into a single entity and component in a world, which may either be vacant or occupied.
• TryFromFilteredError
  Error type returned by TryFrom conversions from filtered entity types (FilteredEntityRef/FilteredEntityMut) to full-access entity types (EntityRef/EntityMut).

Constants

• ON_ADD
  ComponentId for OnAdd
• ON_INSERT
  ComponentId for OnInsert
• ON_REMOVE
  ComponentId for OnRemove
• ON_REPLACE
  ComponentId for OnReplace

Traits

• Command
  A World mutation.
• DynamicComponentFetch
  Types that can be used to fetch components from an entity dynamically by ComponentIds.
• FromWorld
  Creates an instance of the type this trait is implemented for using data from the supplied World.
• WorldEntityFetch
  Types that can be used to fetch Entity references from a World.
