Reverse last action with button?

[jiminy_macca]

Is it possible? Say I click a button that plays a section of a movieclip. Is it possible to reverse that action, or undo it somehow when another button (any other button) is clicked?

This probably isnt the easiest way to do this but lets say you have 3 buttons and one undo button:

button one - calls function 1
button two - calls function 2
button three - calls function 3

function 1{
move an object 10 pix to the right
}

Depending on what your functions do you could create functions that do the oposite ie:

function 1 undo{
move the object 10 pix to the left
}

Whenever button 1,2 or 3 is pressed push an int of the press onto a stack. When the undo button is pressed pop the int off and call that function.

ie:

var stack:Array = new Array();

function1{
//all other stuff
stack.push(1);
}

functioUndo{
var toDo:int = stack.pop();
if(toDo==1)
function1undo();
if(toDo==2)
...
}

Good Luck
