How to get "Current Velocity","Current Duration" and update "Velocity","Duration"

[Carl]

This is the easiest way to get the duration:

 

import com.greensock.*;
import com.greensock.plugins.*;
import com.greensock.easing.*;
TweenPlugin.activate([ThrowPropsPlugin]);



//create a reference to the throwprops tween
var t = ThrowPropsPlugin.to(mc, {throwProps:{x:{velocity:150, resistance:50}, y:{velocity:70, resistance:50}}});

//get its duration()
trace(t.duration());

You can't change the duration of a tween once it has been created. You can change the timeScale though

t.timeScale(2) // will play twice as fast

In the very near future, there will be a VelocityTracker released as part of GSAP, which as its name implies will give you the current velocity of any object, whether it is being tweened, dragged, or moved some other way.

 

Currently the platform does not provide a built-in way to get the current velocity of an object.

 

In the meantime, you can use the velocity tracking shown in the ThrowProps docs:

can i get currentTime of Tween?

[Carl]

In v12 you would use time()

 

in context of the code above

 

t.time()

 

v11

t.currentTime()
