Undo button active state

Question

Hi, I wanted to make a button change color when clicked and remain in that color.

That worked perfectly with the code

upState=over.State

However, I now want to "undo" this when another button is clicked.

(The buttons should only remain in the "changed" color for a certain number of frames.

So every time a button is clicked, only the button that was just recently clicked will be in the changed color.

Is there an efficient way to solve this?

Thanks!

if you have n buttons named b0, b1, ..., bn-1

for(var i: int = 0; i < 3; i++) {
this["b" + i].addEventListener(MouseEvent.MOUSE_DOWN, downF);
this["origUpState"+i] = this["b"+i].upState;
}

function downF(e: MouseEvent): void {
for(var i: int = 0; i < 3; i++) {
this["b" + i].upState = this["origUpState"+i];
}
e.currentTarget.upState = e.currentTarget.overState;
}
