PropertyResolver class abstract

Computes a per-property animated value from a timeline of keyframes.

Subclasses cover the three AnimationProperty flavors with the correct interpolator: linear interpolation for translation and scale, spherical linear interpolation for rotation. Use the PropertyResolver factories to construct one rather than instantiating subclasses directly.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

apply(AnimationTransforms target, double timeInSeconds, double weight) → void

Resolve and apply the property value to a target node. This operation is additive; a given node property may be amended by many different PropertyResolvers prior to rendering. For example, an AnimationPlayer may blend multiple Animations together by applying several AnimationClips.

getEndTime() → double

Returns the end time of the property in seconds.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

makeRotationTimeline(List<double> times, List<Quaternion> values) → PropertyResolver

Creates a rotation resolver that spherically interpolates between the keyframe quaternions in values at the corresponding times.

makeScaleTimeline(List<double> times, List<Vector3> values) → PropertyResolver

Creates a scale resolver that linearly interpolates between the keyframe scales in values at the corresponding times.

makeTranslationTimeline(List<double> times, List<Vector3> values) → PropertyResolver

Creates a translation resolver that linearly interpolates between the keyframe positions in values at the corresponding times.
