For example i have values inside array.
Those values are the IDs of buttons. My question is how to use array efficiently to disable the buttons?
Say you have an array like in comments:
var buttons:Array=new Array('button1','button2','button3');
And you have button objects with names in your MC, namely button1, button2, button3. Use the following:
for each (var s:String in buttons) this[s].disable();
where "disable" is whatever you need to do to disable the button.
