Control Speed

[friendlygiraffe]

Is it possible to control the speed of a Tween dynamically?

 

I want to speed up and slow down / even reverse a tween as it is playing.

 

eg: Speed based on mouse position

 

Thanks

TweenMax tweens, TimelineLites and TimelineMaxes have currentProgress and timeScale values that can be dynamically set even tweened.

 

By using these properties you an accelerate or decelerate their rate of playback, you can even apply eases.

 

you can see this technique in action here:

below is a simple code example of making a TweenMax tween play faster than normal while it is playing:

 

import com.greensock.*;
import com.greensock.easing.*;

var t:TweenMax = TweenMax.to(m1, 4, {x:400, ease:Linear.easeNone});

//after 1 second make the speed of the tween 4x its normal speed
TweenLite.delayedCall(1, changeSpeed);

function changeSpeed(){
t.timeScale = 4;
}
