The simplest would be to us a 2d array like this:
Code:
on (release) {
var dVar = [[_root.image_2, 50],[_root.image_3,100],[_root.image_4,150],[_root.image_5,200],[_root.image_6,250]];
this.mover_mc.onEnterFrame = function() {
for(var i=0;i<dVar.length;i++){
dVar[i][0]._x += ((dVar[i][1] - dVar[i][0]._x) / (0.9 * 10));
if ((Math.abs(dVar[i][0]._x - dVar[i][1]) < 1)) {
dVar[i][0]._x = dVar[i][1];
}
}
delete this.mover_mc.onEnterFrame;
this.mover_mc.removeMovieClip();
};
}
I haven't fully tested it but the array should work just fine.
Edit: Didn't notice the previous post. Either way will work fine.
