Struct bones_framework::prelude::Entity
source · #[repr(C)]pub struct Entity(/* private fields */);
Expand description
An entity index.
They are created using the Entities
struct. They are used as indices with Components
structs.
Entities are conceptual “things” which possess attributes (Components). As an exemple, a Car (Entity) has a Color (Component), a Position (Component) and a Speed (Component).
Implementations§
source§impl Entity
impl Entity
sourcepub fn new(index: u32, generation: u32) -> Entity
pub fn new(index: u32, generation: u32) -> Entity
Creates a new Entity
from the provided index and generation.
⚠️ Warning: It is not generally recommended to manually create
Entity
s unless you know exactly what you are doing. This can be useful in certain advanced or unusual use-cases, but usually you should useEntities::create()
to spawn entities.
sourcepub fn index(&self) -> u32
pub fn index(&self) -> u32
Returns the index of this Entity
.
In most cases, you do not want to use this directly. However, it can be useful to create caches to improve performances.
sourcepub fn generation(&self) -> u32
pub fn generation(&self) -> u32
Returns the generation of this Entity
.
In most cases, you do not want to use this directly. However, it can be useful to create caches to improve performances.
