Detailed Description

Property Target Easing Timeline interpolates a property gradually from its old value to a new value using an easing curve each time a new value is set to the property.

The timeline interpolates a property of specified type on the object specified by its path.

Property Target Easing Timeline interpolates the property value using a from-to animation with an easing curve applied to it.

Note that setting time to playback of this timeline or advancing the timeline in reverse direction is not supported.

Examples

To create a property target easing timeline and set its target property and interpolation settings:

        // Create a property target easing timeline.
        auto timeline = PropertyTargetEasingTimeline::create(domain, ".", Node2D::OpacityProperty, PropertyFieldWhole);
        // Adjust easing interpolation settings.
        timeline->setInterpolationDuration(chrono::milliseconds(500));
        timeline->setEasingFunction(LinearEasingFunction());
        timeline->setEasingMode(AnimationEaseIn);

To create playback for property target easing timeline:

        // Create a context which resolves path to the node.
        SceneGraphTimelinePlaybackContext context(*node);
        // Create playback for property target easing timeline.
        auto playback = timeline->createPlayback(context);

To add playback of property target easing timeline to the clock:

        // Add playback to the clock. Once playback is added to the clock it starts
        // to interpolate its target property whenever the property changes.
        domain->getRootTimelineClock()->addTimelinePlayback(playback);
