Struct TimeOfDay 

pub struct TimeOfDay {
    pub hour: f32,
}

The hour of the day the scene shows (core.time_of_day, a world resource), 0 to 24 (24 is midnight again): the hour a lowering chose for a scene whose source varies over the day (its environment stored at several hours, a program’s material keyed by the hour), the program’s hour where it chose one, else the source’s stated default, counted where it is a default. A program of the source reads it as crate::shader::FrameParameter::TimeOfDay. A world no lowering chose an hour for has none, and a consumer gives such a program no hour.

Fields

hour: f32

Hours since midnight; finite, 0 to 24.

Trait Implementations

impl Clone for TimeOfDay

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TimeOfDay

impl Debug for TimeOfDay

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TimeOfDay

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Resource for TimeOfDay

fn verify(&self, _w: &World) -> Result<(), String>

A finite hour from 0 to 24.

const NAME: &'static str = "core.time_of_day"

fn to_json(&self) -> Result<Option<Value>, JsonError>

As Component::to_json.

const VERSION: u32 = 1

fn references(&self, _out: &mut Vec<Entity>)

The entities this resource refers to, appended to out. A resource holding entity references must declare every one of them and implement Resource::retain_references.

fn retain_references(&mut self, _keep: &dyn Fn(Entity) -> bool)

Forget every reference to an entity keep refuses (set it to “none”). The world calls it whenever entities leave it (World::despawn, World::retain, World::move_components) and on the copy a World::subset or World::split_off part gets, so a resource never refers to an entity its world lacks.

impl Serialize for TimeOfDay

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
