ActionScript 3.0 :: Using One Series Of Conditional Statements For Several Different Objects?

-Let's say you have several doors on stage for a game.
�
-Each door has the ability to change color.
�
-When any two doors are the same color, a player can move between those two doors.
�
To do this, I use code similar to the following:
���
doorThree.addEventListener(MouseEvent.CLICK,dooraction);
function dooraction(event:MouseEvent){
if ("Blue") {

[Code]....
�
Is there a way to use this one series of If statements for all doors, or must I copy and paste the same instructions for each door instance? In the game I'm planning, each door actually has more than two dozen states, so if I can use just one series of if statements, I'd like to do that.
