I want to make a box come from off screen then bounce back and forth and then come settled down in the middle of the screen. It can be random bouning intervels or a set amount, it really does not matter. Does anyone think they can point me in the right direction?  
Thank ya

Sure… make the box a movie clip, place it where you want it to start from, then add the following code to the outside of it.

onClipEvent(enterFrame){  
xVelocity=this.\_x-200; //assuming that your movie is 400 across  
xVelocity\*=.94;  
this.\_x+=xVelocity;  
}

At least I think that will work. If not, just tell me and I’ll fix it. It may be that the numbers are reversed… I’m doing it from memory. 🙂

you can try this. I find it to be a little choppy, but it works

onClipEvent(enterFrame){  
diff=200-this.\_x;  
velocity+=diff;  
velocity\*=.94;  
\_x+=velocity;  
}

You can just adjust it like as you wish:

```auto
onClipEvent(enterFrame){
  diff=200-this._x;
  velocity+=diff*.2;
  velocity*=.94;
  _x+=velocity;
}

```

And there’s a Springs tutorial too.

pom 🙂
