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:

```auto

    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.

```auto

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:

```auto

   mag = mag * 1.2;

```

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

```auto

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

```
