Detailed Description

Playback object for Timelines.

TimelinePlayback keeps track of how timeline is played.

To perform playback of Timeline, create a TimelinePlayback object by calling the Timeline::createPlayback() function of Timeline. After that you add playback to a TimelineClock by calling its TimelineClock::addTimelinePlayback() function. TimelineClock will advance the global time of TimelinePlayback object which in turn will advance Timeline.

Playback is associated with its timeline during its complete lifetime. It is possible to create multiple playbacks from a single timeline. Each playback of timeline has its own track of how timeline is played at current point in time:

        // Create first playback for timeline and add it to the clock.
        SceneGraphTimelinePlaybackContext firstPlaybackContext(*firstNodeToAnimate);
        TimelinePlaybackSharedPtr firstPlayback = timeline->createPlayback(firstPlaybackContext);
        timelineClock->addTimelinePlayback(firstPlayback);
        // Create second playback for timeline and add it to the clock.
        SceneGraphTimelinePlaybackContext secondPlaybackContext(*secondNodeToAnimate);
        TimelinePlaybackSharedPtr secondPlayback = timeline->createPlayback(secondPlaybackContext);
        timelineClock->addTimelinePlayback(secondPlayback);

Once playback of timeline starts playing timeline, none of timeline properties should be changed.

Global time

After TimelinePlayback is added to a clock, the clock applies it by periodically calling its tick() function. Delta time argument of this function is interpreted by TimelinePlayback as change in its global time. Timeline start time and duration are defined in global time space. Playback calculates all its parameters from global time: current iteration index, progress time inside the iteration, whether it is applied and so on. Before playback is added to a clock, its global time is undefined.

To manually set global time of TimelinePlayback call its setGlobalTime() function:

// Set global time of timeline playback to 10 milliseconds.

timelinePlayback->setGlobalTime(chrono::milliseconds(20));

To retrieve global time of TimelinePlayback call its getGlobalTime() function:

// Get global time of timeline playback.

chrono::milliseconds globalTime = timelinePlayback->getGlobalTime();

Note that setting global time of TimelinePlayback which has parent TimelinePlayback can result in undefined behavior.

Progress time

When global time is changing, TimelinePlayback calculates progress time from it. Progress time is defined in Timeline's progress time space and it is the time at which the progress of timeline is applied. TimelinePlayback notifies its subclasses every time it calculates its progress time from global time. TimelinePlayback can notify its subclasses about gradual change in progress time or about reset of progress time. When TimelinePlayback notifies its subclasses that progress time has changed gradually, they advance their timelines gradually from previous progress time value to the new one. When TimelinePlayback notifies its subclasses that progress time has been reset to a new value they reset their animations to new progress time. Before playback is added to a clock, its progress time is undefined. After playback is added to a clock, its progress time is always within timeline progress interval.

To retrieve the progress time of TimelinePlayback call its getProgressTime() function:

// Get progress time of timeline playback.

chrono::milliseconds progressTime = timelinePlayback->getProgressTime();

Applied state

Depending on global time TimelinePlayback can decide whether its timeline should be applied or not. TimelinePlayback is not applied (that is, its timeline is not applied) if its global time goes before timeline start time or if TimelinePlayback's parent playback is not applied. In all other cases TimelinePlayback is applied, even if its global time advances past timeline duration interval. When TimelinePlayback changes from applied to not applied (or the other way around) it notifies its subclasses so they start or stop applying their Timelines. If TimelinePlayback with child TimelinePlaybacks changes its applied state, this change propagates down the hierarchy of playbacks. For example, if parent TimelinePlayback becomes not applied, then its child playbacks also become not applied even though they have their global times inside Timeline duration interval.

After the global time of TimelinePlayback has come to an end of its Timeline duration and it is still advancing beyond the end of Timeline duration, then TimelinePlayback is still applied. In this case TimelinePlayback clamps the progress time of timeline to the last valid value inside Timeline's progress interval and keeps applying the Timeline.

To retrieve the applied state of TimelinePlayback call its isApplied() function:

// Get applied state of timeline playback.

bool isPlaybackActive = timelinePlayback->isApplied();

Completion

At some point every TimelinePlayback can become complete. Root TimelinePlayback becomes complete when its total time goes past its timeline duration. In this case TimelinePlayback propagates completion down the tree of child playbacks so each of them can notify that it is complete. It means that child TimelinePlayback is complete only when its root playback is complete. However, even though TimelinePlayback has notified about its completion, it continues to apply its Timeline. TimelinePlayback stops applying its timeline only after it is destroyed.

override

Destructor.

Member Function Documentation

◆ setParent()

void kanzi::TimelinePlayback::setParent ( TimelinePlayback * playback )

Sets parent playback.

This function should only be called before this playback or parent playback are added to the clock.

Parameters

playback Parent playback.

◆ setCompleteCallback()

void kanzi::TimelinePlayback::setCompleteCallback ( CompleteCallback callback )

Sets complete callback.

Parameters

callback which is called when playback is complete.

◆ getState()

State kanzi::TimelinePlayback::getState ( ) const

Gets current state of playback.

Returns: Playback status.

◆ tick()

void kanzi::TimelinePlayback::tick ( chrono::milliseconds deltaTime )

Advances TimelinePlayback's global time by delta time and calculates new progress time from it as well as other parameters such as current iteration index, etc.

During the call to this function TimelinePlayback can call its tickOverride() and onProgressTimeResetOverride() functions multiple times. Also TimelinePlayback can become complete during the call to this function (and onPlaybackCompletedOverride() function called) or its applied state can change (and onAppliedStateChangedOverride() function called).

Parameters

deltaTime Delta time of Playback's global time since last tick.

◆ getGlobalTime()

Gets current global time of TimelinePlayback.

Returns: Global time of playback.

◆ setGlobalTime()

void kanzi::TimelinePlayback::setGlobalTime ( chrono::milliseconds time )

Sets global time of playback and calculates new global time from it as well as other parameters such as current iteration index, etc.

During the call to this function Playback will call its onProgressTimeResetOverride() function. Also Playback can become complete during the call to this function (and onPlaybackCompletedOverride() function called) or its applied state can change (and onAppliedStateChangedOverride() function called).

Parameters

time	Global time of playback.

◆ getProgressTime()

chrono::milliseconds kanzi::TimelinePlayback::getProgressTime ( ) const
