Struct bevy::render::view::RenderLayers

pub struct RenderLayers(_);

Describes which rendering layers an entity belongs to.

Cameras with this component will only render entities with intersecting layers.

There are 32 layers numbered 0 - TOTAL_LAYERS. Entities may belong to one or more layers, or no layer at all.

The Default instance of RenderLayers contains layer 0, the first layer.

An entity with this component without any layers is invisible.

Entities without this component belong to layer 0.

Implementations

impl RenderLayers

pub const TOTAL_LAYERS: usize = 32usize

The total number of layers supported.

pub const fn layer(n: u8) -> RenderLayers

Create a new RenderLayers belonging to the given layer.

pub const fn all() -> RenderLayers

Create a new RenderLayers that belongs to all layers.

pub const fn none() -> RenderLayers

Create a new RenderLayers that belongs to no layers.

pub fn from_layers(layers: &[u8]) -> RenderLayers

Create a RenderLayers from a list of layers.

pub const fn with(self, layer: u8) -> RenderLayers

Add the given layer.

This may be called multiple times to allow an entity to belong to multiple rendering layers. The maximum layer is TOTAL_LAYERS - 1.

Panics

Panics when called with a layer greater than TOTAL_LAYERS - 1.

pub const fn without(self, layer: u8) -> RenderLayers

Removes the given rendering layer.

Panics

Panics when called with a layer greater than TOTAL_LAYERS - 1.

pub fn iter(&self) -> impl Iterator<Item = u8>

Get an iterator of the layers.

pub fn intersects(&self, other: &RenderLayers) -> bool

Determine if a RenderLayers intersects another.

RenderLayerss intersect if they share any common layers.

A RenderLayers with no layers will not match any other RenderLayers, even another with no layers.

Trait Implementations

impl Clone for RenderLayers

fn clone(&self) -> RenderLayers

Returns a copy of the value.
