struct Animated

Swift

struct Animated<T> where T : Animatable

A property that moves toward a target over time.

Lives on the node, not in a view. Views are rebuilt every frame and carry no identity; nodes persist, already own visual state like fillColor and scrollOffset, and can therefore interpolate without re-running a single body. Driving animation from the view side would recompute the whole tree — Mirror-based state transplant included — sixty times a second to change a colour.

Methods

mutating func animate(to value: T, duration seconds: Double = 0.12, curve: AnimationCurve = .easeOut)

Starts moving toward value. Retargeting mid-flight restarts from wherever the value currently is, so an interrupted animation continues smoothly rather than jumping back to its original start.

mutating func snap(to value: T)

Jumps immediately, cancelling any animation in flight.

Sources/LavaUI/Animation.swift:108

mutating func step(_ now: Double) -> Bool

Advances to now. Returns true while still animating.
