vairable MovieClip speed based on button press

[BabaBlackSheep]

I want to play A movieClip when a button is pressed.

faster the button is pressed, Faster is the Clip playback and vice versa.

So Playback of clip will be variable based on keypress.

 

How is this doable using greensock ?

Hi and welcome to the GreenSock forums.

 

Every tween has a timeScale() that can be adjusted.

When you increase the timeScale() of a tween it will play faster.

 

You can create a tween using our FramePlugin (enabled by default in TweenMax) that will scrub the playhead of a movie clip forward over time (demo)

 

The code below will make a movie clip animation play faster each time the stage is clicked:

 

import com.greensock.*;
import com.greensock.easing.*;
import flash.events.MouseEvent;


//prevent mc from playing on its own
mc.stop();


//create a tween using frame plugin to move playhead of mc to frame 60 over the course of 1 second
var tween:TweenMax = TweenMax.to(mc, 1, {frame:60, repeat:200, ease:Linear.easeNone}); //use Linear ease for best results


//click the stage to increase the speed of the tween that controls mc
stage.addEventListener(MouseEvent.CLICK, goFaster);


function goFaster(e:MouseEvent):void {
tween.timeScale(tween.timeScale() + 0.1) 
trace(tween.timeScale())
}

Flash CC Fla and swf attached.

Very Useful.Thank you.
Can we do this for a loaded FLV too ? instead of movieClip ?
