Some button as

I’ve got four buttons on the stage and im using this script to animate them when the mouse rolls over:


onClipEvent(load){
 speed = 4
}
onClipEvent(enterFrame){
 if(this.hitTest(_root._xmouse,_root._ymouse)){
  this.ts = 200
 }else{
  this.ts = 100
 }
 this._xscale  += (this.ts - this._xscale)/speed
 this._yscale  += (this.ts - this._yscale)/speed
}

how can I get the other buttons to keep their distance when the activated one grows in size?

Thanks in advance.
