G’day.
I’m was trying to make the vibration effect in the tutorials to happen in a rollover, but I failed miserably. I did a google search and a search on the fourms but found nothing that helped me.
Cheers. :puzzle:

What tutorial?
I can suggest one technique for a rapid random vibration:
1. Make sure the rollOver object is a movieclip instance.
2. Convert this to a movieclip.
3. On the nested clip, put keyframes at frame 1 and 2.
4. On the instance on frame 2, apply this script:
[AS]
onClipEvent(enterFrame){
this.\_x = random(5);
this.\_y = random(5);
}
[/AS]
put a stop(); action on the first and second frame of this nested clip.
1. On the parent clip type:
[AS]
on(rollOver){
this.play();
}
on{rollOut){
this.play();
}
[/AS]
You can lay one clip on top of the other and reduce the alpha to give a better vibration effect. If you do this, you have to give them all an instance name, because the this keyword will only work for the top object. Works best at a high frame rate, eg 18+.
