Struct Environment 

pub struct Environment {
    pub sun: Option<Entity>,
    pub ambient: Option<Ambient>,
}

The scene’s environment as the source authored it. sun: the entity whose directional core.light the source names as its sun (a scene setting naming one light, not the brightest light a writer picks); None when the source names none, or in a part of a world that does not hold the sun (a subset or a cell). ambient: the scene’s ambient light (Ambient); None when the source states none or a lowering has not stated its meaning. Sky and fog are not here until their meaning and units are established for a source.

Fields

sun: Option<Entity>

ambient: Option<Ambient>

Trait Implementations

impl Clone for Environment

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Environment

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

Formats the value using the given formatter.

impl Default for Environment

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Environment

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

Equality operator ==.

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

Inequality operator !=.

impl Resource for Environment

const VERSION: u32 = 2

2: ambient.

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

The sun is a directional light; the ambient is finite and not negative.

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

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

As Component::to_json.

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 Environment

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
