[−]Struct bevy::ecs::Entity
Lightweight unique ID of an entity
Obtained from World::spawn
. Can be stored to refer to an entity in the future.
Implementations
impl Entity
pub fn new(id: u32) -> Entity
Creates a new entity reference with a generation of 0
pub fn to_bits(self) -> u64
Convert to a form convenient for passing outside of rust
Only useful for identifying entities within the same instance of an application. Do not use for serialization between runs.
No particular structure is guaranteed for the returned bits.
pub fn from_bits(bits: u64) -> Entity
Reconstruct an Entity
previously destructured with to_bits
Only useful when applied to results from to_bits
in the same instance of an application.
pub fn id(self) -> u32
Extract a transiently unique identifier
No two simultaneously-live entities share the same ID, but dead entities' IDs may collide with both live and dead entities. Useful for compactly representing entities within a specific snapshot of the world, such as when serializing.
