Method Summary

void	onTimelinePulse(float durationFraction, float timelinePosition) Indicates that the timeline pulse has happened.
void	onTimelineStateChanged(Timeline.TimelineState oldState, Timeline.TimelineState newState, float durationFraction, float timelinePosition) Indicates that the timeline state has changed.

Method Detail

onTimelineStateChanged

void onTimelineStateChanged(Timeline.TimelineState oldState,
                            Timeline.TimelineState newState,
                            float durationFraction,
                            float timelinePosition)

Indicates that the timeline state has changed.

Parameters:

oldState - The old timeline state.

newState - The new timeline state.

durationFraction - The current timeline duration fraction.Is guaranteed to be in 0.0-1.0 range. The rate of change of this value is linear, and the value is proportional to Timeline.setDuration(long).

timelinePosition - The current timeline position. Is guaranteed to be in 0.0-1.0 range. The rate of change of this value is not necessarily linear and is affected by the Timeline.setEase(org.pushingpixels.trident.ease.TimelineEase) .

onTimelinePulse

void onTimelinePulse(float durationFraction,
                     float timelinePosition)

Indicates that the timeline pulse has happened.

Parameters:

durationFraction - The current timeline duration fraction.Is guaranteed to be in 0.0-1.0 range. The rate of change of this value is linear, and the value is proportional to Timeline.setDuration(long).

timelinePosition - The current timeline position. Is guaranteed to be in 0.0-1.0 range. The rate of change of this value is not necessarily linear and is affected by the Timeline.setEase(org.pushingpixels.trident.ease.TimelineEase) .
