Detailed Description

template<typename TValueType>
class kanzi::KeyframeAnimation< TValueType >

Template class for keyframe animations.

Template Parameters
TValueTypeDefines the type of the value you want to animate. For example, float, bool, int, ColorRGBA.

The Kanzi animation system consists animations and timelines: animations define how to animate a property, and timelines map the animations to time and to objects you want to animate.

Keyframe animation uses keyframes that define the property value and time at which the animation reaches that value. In Kanzi you can create linear, step, and Bezier keyframes.

Examples

To create a keyframe animation:

// Create a float keyframe animation.
// Create and add keyframes to the keyframe animation. This keyframe animation contains two linear keyframes.
// Create a linear keyframe at second 0 with the value 0.
keyframeAnimation->addLinearKeyframe(chrono::seconds::zero(), 0.0f);
// Create a linear keyframe at second 1 with the value 100.
keyframeAnimation->addLinearKeyframe(chrono::seconds(1), 100.0f);

To animate a property value in a node using a keyframe animation:

// Create a property timeline and apply the keyframeAnimation keyframe animation to the Layout Width property
// to animate the width of the current node.

To animate a property field value in a node using a keyframe animation:

// Create a property field animation timeline and apply it to the Render Transformation property of the current node.
// Rotate the current node by animating the Rotation Z property field of the Render Transformation property
// with the keyframeAnimation keyframe animation.
propertyFieldTimeline->addEntry(PropertyFieldRotationZ, keyframeAnimation);

To create a keyframe animation that uses Bezier keyframes to move an object on a sideways figure eight shaped path:

// Create two float keyframe animations: one to animate the object on the x axis,
// the other to animate the object on the y axis.
// Create float keyframe animation keyframeAnimationX that uses linear keyframes
// to animate the movement of the object on the x axis.
// Create a linear keyframe at second 0 with the value 0.
keyframeAnimationX->addLinearKeyframe(chrono::seconds::zero(), 0.0f);
// Create a linear keyframe at second 4 with the value 4.
// At this keyframe the object reaches the furthest point on the x axis.
keyframeAnimationX->addLinearKeyframe(chrono::seconds(4), 4.0f);
// Create a linear keyframe at second 8 with the value 0.
// At this keyframe the object returns to the same position it had at the first keyframe.
keyframeAnimationX->addLinearKeyframe(chrono::seconds(8), 0.0f);
// Create float keyframe animation keyframeAnimationY that uses Bezier keyframes
// to animate the movement of the object on the y axis.
// Create a linear keyframe at second 0 with the value 0. When you use Bezier keyframes,
// you can use any type of keyframe for the first keyframe, because you need this keyframe
// only to provide the information for the starting position.
keyframeAnimationY->addLinearKeyframe(chrono::seconds::zero(), 0.0f);
// Create a Bezier keyframe at second 4 with the value 0 and two control points.
// You use the control points to set the position of the keyframe.
keyframeAnimationY->addBezierKeyframe(chrono::seconds(4), 0.0f, Vector2(0.5f, 4.0f), Vector2(0.5f, -4.0f));
// Create a Bezier keyframe at second 8 with the value 0 and two control points.
// This keyframe uses the same control points, but because the keyframeAnimationX
// animation moves the object on the x axis back to its starting position, this keyframe
// is a mirror image of the previous keyframe.
keyframeAnimationY->addBezierKeyframe(chrono::seconds(8), 0.0f, Vector2(0.5f, 4.0f), Vector2(0.5f, -4.0f));
// Create a property field animation timeline and apply it to the Render Transformation property of the current node.
// Move the current node on the x axis by animating the Translation X property field of the Render Transformation property
// with the keyframeAnimationX keyframe animation.
timeline->addEntry(PropertyFieldTranslationX, keyframeAnimationX);
// Move the current node on the y axis by animating the Translation Y property field of the Render Transformation property
// with the keyframeAnimationY keyframe animation.
timeline->addEntry(PropertyFieldTranslationY, keyframeAnimationY);

To play an animation regardless of the timeline type:

// Create the playback context and the timeline playback for the node defined in the item2d.
SceneGraphTimelinePlaybackContext context(*item2d);
// Create the playback for the timeline defined in the propertyFieldTimeline.
TimelinePlaybackSharedPtr playback = propertyFieldTimeline->createPlayback(context);
// Start the animation.
domain->getRootTimelineClock()->addTimelinePlayback(playback);

Returns new animated value given current value and time.

Classes derived from ValueAnimation define data and algorithms to calculate the value returned by this function.

Parameters
currentValueCurrent value that is used as basis for animation calculations.

Implements kanzi::ValueAnimation< TValueType >.

template<typename TValueType >
virtual optional<chrono::milliseconds> kanzi::KeyframeAnimation< TValueType >::getDurationOverride ( )
inlineprotectedvirtual

Virtual function the derived classes should overload to return duration.

Default implementation returns nullopt to indicate infinite animation.

Reimplemented from kanzi::AbstractAnimation.
