Detailed Description

Use TimelineClock to update a Timeline based on time.

To perform a playback of a Timeline, you will have to create a TimelinePlayback object by calling the Timeline::createPlayback(). To add a playback to a TimelineClock, call TimelineClock::addTimelinePlayback() function. TimelineClock will advance the global time of TimelinePlayback object which in turn will advance the Timeline. So in other words, adding playback to a clock triggers the animation.

To add a playback to a Timeline call TimelineClock::addTimelinePlayback() function:

        // Create playback context.
        SceneGraphTimelinePlaybackContext context(*nodeToAnimate);
        // Create playback for timeline.
        TimelinePlaybackSharedPtr timelinePlayback = timeline->createPlayback(context);
        // Add playback to the clock.
        timelineClock->addTimelinePlayback(timelinePlayback);

To remove an existing playback from a Timeline call TimelineClock::removeTimelinePlayback() function:

// Remove playback from the clock.

timelineClock->removeTimelinePlayback(*timelinePlayback);

Constructor.

Parameters

domain Domain.

Member Function Documentation

◆ addTimelinePlayback()

void kanzi::TimelineClock::addTimelinePlayback ( TimelinePlaybackSharedPtr timelinePlayback )

Adds a Timeline playback.

A newly added Timeline playback is initially added to the list of new playbacks, and later moved to the list of the existing playbacks. The new playbacks are updated with a zero time delta, and the existing playbacks are updated with full time delta during the update.

Parameters

timelinePlayback Timeline playback to add.

◆ removeTimelinePlayback()

void kanzi::TimelineClock::removeTimelinePlayback ( const TimelinePlayback & timelinePlayback )

Removes a Timeline playback.

Parameters

timelinePlayback Timeline playback to be removed.

◆ tick()

void kanzi::TimelineClock::tick ( chrono::milliseconds delta )

Ticks all playbacks in the Timeline clock.

A newly added Timeline playback only advances one frame per tick, it can not be ticked forward with possibly arbitrarily long delta time since last frame.

Parameters

delta Delta time since last frame.

◆ getLastTickMeasurement()

chrono::microseconds kanzi::TimelineClock::getLastTickMeasurement ( ) const

inline

Gets time spent on last tick operation.

◆ getActiveTimelinePlaybackCount()

size_t kanzi::TimelineClock::getActiveTimelinePlaybackCount ( ) const

inline

Returns the number of active Timeline playbacks.

The number of active Timeline playbacks may differ from total number of Timeline playbacks as some playbacks may be inactive.

Returns: The number of active Timeline playbacks.

◆ hasActiveTimelinePlaybacks()

bool kanzi::TimelineClock::hasActiveTimelinePlaybacks ( ) const

inline

Returns whether there are any active Timeline playbacks present.

Active playback is the playback which is not paused, and not yet completed nor stopped.

Returns: If at least one Timeline playback is active, true, otherwise false.

◆ getTimelinePlaybackCount()

size_t kanzi::TimelineClock::getTimelinePlaybackCount ( ) const

Returns the number of Timeline playbacks.

This is the total number of playbacks, active or otherwise. This number also includes the Timeline playbacks added to the current frame.

Returns: Number of Timeline playbacks referenced by the root Timeline clock.

◆ create()

static TimelineClockSharedPtr kanzi::TimelineClock::create ( Domain * domain )

inlinestatic

Creates a Timeline clock.

Parameters

domain Domain.

Returns: Pointer to the Timeline clock.

◆ removeTimelinePlaybackFromContainer()

bool kanzi::TimelineClock::removeTimelinePlaybackFromContainer	(	const TimelinePlayback &	timelinePlayback,
		TimelinePlaybackContainer &	container
	)

protected

Removes a Timeline playback from a Timeline playback container.

Parameters

timelinePlayback	Timeline playback to remove.
container	Container to remove from.

Returns: If a playback is found and removed, true, otherwise false.

◆ isTimelinePlaybackActive()

static bool kanzi::TimelineClock::isTimelinePlaybackActive ( const TimelinePlayback & timelinePlayback )

inlinestaticprotected

Checks if the given Timeline playback is active or not.

Parameters

timelinePlayback Timeline playback under the check.

Returns: If if the Timeline playback is active, true, otherwise false.
