Overview

The object:getDuration() method returns the duration of the Timeline in milliseconds.

Notes

  • This value will be affected by the timeline’s speed scale.

  • In the instance of an endless timeline (infinite iterations on a child tween), this value will be nil because there is effectively no pre-determined duration.

Syntax

object:getDuration()

Example

local object1 = display.newRect( 50, 50, 100, 100 )

-- Create a timeline object
local timelineParams = {
    tweens = {
        { startTime=1000, tween={ object1, { x=400 }, { time=4000, iterations=5 } } },
        { startTime=2000, tween={ object1, { y=400 }, { time=4000, easing=easing.outQuad } } }
    },
    delay = 1000
}
local newTimeline = animation.newTimeline( timelineParams )

-- Set the timeline playing
newTimeline:resume()

-- Get the timeline's playing duration
local duration = newTimeline:getDuration()
print( duration )  --> 21000
