peepz,

i want to call a funtion once within a onEnterFrame, butthe problem is that the onEnterFrame needs to go on and execute the function only once…(if its between the desired x positions (see script below))

my code

```auto

onClipEvent(enterFrame)
{
 if(this._x < -150 && this._x > -1600)
 {
  //execute once!
  fadeIn()
 }
 else{
  //execute once!
  fadeOut()
 }
 this._x = (this._parent.mcBG._x * 1.4)-1950
 this._y = (this._parent.mcBG._y * 1.8)-160
}

```

hope u can help…  
thanks already!
