Camera: Base components for a camera. You will need other components to make a fully-functioning camera.

Extends: ambient_core::transform::Transformable

Required:

• local_to_world: Transformation from the entity’s local space to worldspace.
• near: The near plane of this camera, measured in meters.
• projection: The projection matrix of this camera. This can be driven by other components, including perspective and perspective_infinite_reverse.
• projection_view: The composition of the projection and view (inverse-local-to-world) matrices.
• active_camera: The camera with the highest active_camera value will be used for rendering. Cameras are also filtered by the user_id. If there’s no user_id, the camera is considered global and potentially applies to all users (if its active_camera value is high enough).
• inv_local_to_world: Converts a world position to a local position. This is automatically updated.

Optional:

• translation: The translation/position of this entity.
• rotation: The rotation of this entity.
• scale: The scale of this entity.
• main_scene: Either the main or UI scene must be specified for this camera to be used.
• ui_scene: Either the main or UI scene must be specified for this camera to be used.
• user_id: If set, this camera will only be used for the specified user.

Trait Implementations

impl Clone for Camera

fn clone(&self) -> Camera

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Concept for Camera

fn make(self) -> Entity

Creates an entity with the components defined by this concept.

fn get_spawned(id: EntityId) -> Option<Camera>

If the entity with id exists and has the components defined by this concept, returns this concept with all of the values of the components in the entity.

fn get_unspawned(entity: &Entity) -> Option<Camera>

If the entity has the components defined by this concept, returns this concept with all of the values of the components in the entity.

fn contained_by_spawned(id: EntityId) -> bool

Returns true if id exists and contains the components defined by this concept.

fn contained_by_unspawned(entity: &Entity) -> bool

Returns true if contains the components defined by this concept.

fn spawn(self) -> EntityId

where Self: Sized,

Spawns this concept into the world. If you want to modify state before spawning, use make instead.
