Scusate ragazzi alla fine ho risolto così:
stop();
import caurina.transitions.Tweener;
import caurina.transitions.properties.FilterShortcuts;
FilterShortcuts.init();
var n:Number = 1;
//var v:String = n.toString();
//var c:String = "this.aohmv" + v;
trace (n);
Tweener.addTween(this["aohmv"+n],{_Blur_blurX:5,_Blur_blurY:5,time:1,transition:"linear"});
avanti = function () {
if (n > 3) {
n = 3
};
//var v:String = n.toString();
//var c:String = "this.aohmv" + v;
Tweener.addTween(this["aohmv"+n],{_Blur_blurX:5,_Blur_blurY:5,time:1,transition:"linear"});
Tweener.addTween(this["aohmv"+(n-1)],{_Blur_blurX:0,_Blur_blurY:0,time:1,transition:"linear"});
trace (n);
}
indietro = function (){
if (n < 1) {
n = 1
};
//var v:String = n.toString();
//var c:String = "this.aohmv" + v;
Tweener.addTween(this["aohmv"+(n+1)],{_Blur_blurX:0,_Blur_blurY:0,time:1,transition:"linear"});
Tweener.addTween(this["aohmv"+n],{_Blur_blurX:5,_Blur_blurY:5,time:1,transition:"linear"});
trace (n);
}
