The IRunnable property interface.

This interface provides basic properties of a "runnable" object, e.g. a timeline (Start, pause, stop, rewind).

Methods


Reset()

Reset the timeline. Stop the timeline, reset the WasRunning() state and call Rewind().

Boolean Reset()

Returns
Boolean true if successful.

ResetTo(startTime)

Reset the timeline to a specified start time. Set the start time and call Reset().

Boolean ResetTo(Number startTime)

Parameters
startTimeThe start time in seconds.
Returns
Boolean true if successful.

Start()

Start or continue the timeline. Does not modify the current time and loop.

Boolean Start()

Returns
Boolean true if successful.

Start(startTime, endTime)

Start the timeline with specified parameters. Set start/end time, calls Rewind() and Start().

Boolean Start(Number startTime, Number endTime)

Parameters
startTimeThe start time in seconds.
endTimeThe end time in seconds.
Returns
Boolean true if successful.

Start(startTime, endTime, numberOfLoops)

Start the timeline with specified parameters. Set start/end time, number of loops, calls Rewind() and Start().

Boolean Start(Number startTime, Number endTime, Integer numberOfLoops)

Parameters
startTimeThe start time in seconds.
endTimeThe end time in seconds.
numberOfLoopsNumber of loops.
Returns
Boolean true if successful.

Start(startTime, endTime, loopStartTime, loopEndTime, numberOfLoops)

Start the timeline with specified parameters. Set start/end time, loop start/end time, number of loops, calls Rewind() and Start().

Boolean Start(Number startTime, Number endTime, Number loopStartTime, Number loopEndTime, Integer numberOfLoops)

Parameters
startTimeThe start time in seconds.

Returns
Boolean true if successful.

Pause()

Pause the timeline.

Boolean Pause()

Returns
Boolean true if timeline was paused, false if timeline is not running.

Stop()

Stop the timeline. Rewind() is called if auto rewind is enabled.

Integer GetNumberOfLoops()

Returns
Integer The number of loops.

Returns
Boolean true if successful.

GetTimeShift()

Get the time shift value.

Number GetTimeShift()

Returns
Number The time shift value.

SetTimeOffset(timeOffset)

Set the time offset value.

Boolean SetTimeOffset(Number timeOffset)

Parameters
timeOffsetThe time offset value.
Returns
Boolean true if successful.

GetTimeOffset()

Get the time offset value.

Number GetTimeOffset()

Returns
Number The time offset value.

SetTimeScale(timeScale)

Set the time scale factor. The recent tick duration is multiplied by the time scale factor and added to the current time each logic tick. The default time scale factor is 1.

Boolean SetTimeScale(Number timeScale)

Parameters
timeScaleThe time scale factor.
Returns
Boolean true if successful.

GetTimeScale()

Get the time scale factor.

Number GetTimeScale()

Returns
Number true The time scale factor.

IsRunning()

Check if the timeline is running. A timeline can be started by calling Start() and stopped by calling Stop().

Boolean IsRunning()

Returns
Boolean true if running.

IsPaused()

Check if the timeline is paused. A timeline can be paused by calling Pause() and continued by calling Start().

Boolean IsPaused()

Returns
Boolean true if paused.
