Struct MorphState 

pub struct MorphState {
    pub active: bool,
    pub progress: f32,
    pub freeze_seq: u64,
}

The live state of a node’s morph transition, written by the morph channel in crate::transition (retarget on key change, per-frame progress) and read by render extraction (the freeze request + blend pass). Inserted on first activation; removed on demotion.

The frozen snapshot is anchored to the node’s LAYOUT rect: the blend stretches it onto the current capture rect (0..1 UV over both textures), so scrolling or moving the node mid-flight carries both images together. A size change across the swap stretches the old appearance — handling that gracefully is the app’s responsibility.

Fields

active: bool

A morph is in flight: the blend pass runs. Cleared one frame after the runner settles (the settle frame renders at exactly progress = 1.0, which the morph-shader identity contract makes pixel-equal to no pass — so dropping the pass next frame can never flash).

progress: f32

Engine-owned blend progress, 0.0..=1.0 (clamped — spring specs may overshoot).

freeze_seq: u64

Bumped on every retarget; the render side freezes the snapshot when it sees a sequence it hasn’t consumed yet.

Trait Implementations

impl Clone for MorphState

fn clone(&self) -> MorphState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for MorphState

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = ::bevy::ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns ComponentRelationshipAccessor required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add ComponentHook for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert ComponentHook for this Component if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard ComponentHook for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove ComponentHook for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn ComponentHook for this Component if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

impl Debug for MorphState

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

Formats the value using the given formatter.

impl Default for MorphState

fn default() -> MorphState

Returns the “default value” for a type.

impl PartialEq for MorphState

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

Equality operator ==.

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

Inequality operator !=.
