Modules§
- Contains error types returned by bevy’s schedule.
- Contains types that allow disjoint mutable access to a
World
.
Structs§
- Densely and efficiently stores a queue of heterogenous types implementing
Command
. - A
World
reference that disallows structural ECS changes. This includes initializing resources, registering components or spawning entities. - Provides mutable access to a single entity and all of its components.
- A read-only reference to a particular
Entity
and all of its components. - A mutable reference to a particular
Entity
, and the entire world. This is essentially a performance-optimized(Entity, &mut World)
tuple, which caches theEntityLocation
to reduce duplicate lookups. - Provides mutable access to a single entity and some of its components defined by the contained
Access
. - Provides read-only access to a single entity and some of its components defined by the contained
Access
. - A view into an occupied entry in a
EntityWorldMut
. It is part of theEntry
enum. - Trigger emitted when a component is added to an entity.
- Trigger emitted when a component is inserted on to to an entity.
- Trigger emitted when a component is removed from an entity.
- An iterator that spawns a series of entities and returns the ID of each spawned entity.
- A view into a vacant entry in a
EntityWorldMut
. It is part of theEntry
enum. - Stores and exposes operations on entities, components, resources, and their associated metadata.
- A unique identifier for a
World
.
Enums§
- A view into a single entity and component in a world, which may either be vacant or occupied.
