Vibration effect.....make more violent?

1

i have text which i have created to vibrate using this code

onClipEvent (load) {
// movie width/height
height = 150;
width = 500;
this._xscale = this._yscale=temp;
// setting initiaion position
cx = this._x;
cy = this._y;
}
onClipEvent (enterFrame) {
// causes the object to be offset
this._x = cx+(1+Math.random()*5);
this._y = cy+(1+Math.random()*5);
}

i edited it from the original kirupa tutorial on circle vibration, but does anyone know how to edit that so the vibration becomes more violent over time?

The magnitude of the vibration is given by the ‘5’ in the following lines:


    this._x = cx+(1+Math.random()*5);
    this._y = cy+(1+Math.random()*5);

If you modify the script as follows, the magnitude will increase with time.


onClipEvent (load) {
    // movie width/height
    height = 150;
    width = 500;
    this._xscale = this._yscale=temp;
    // setting initiaion position
    cx = this._x;
    cy = this._y;
    mag = 5;
}
onClipEvent (enterFrame) {

    mag = mag + 1;  // increase magnitutde

    this._x = cx+(1+Math.random()*mag);
    this._y = cy+(1+Math.random()*mag);
}

There are many ways you can increase the magnitude, besides adding 1.
Try this one instead:


   mag = mag * 1.2;

Also, you may want to try vibrating this way (to keep the oscillations centered)


    this._x = cx+Math.random()*mag - mag/2;
    this._y = cy+Math.random()*mag - mag/2;

hey jim thanks a lot thats a great help
