Need to get a variable from a collided object.

My game is a dungeon crawler. Doors are randomly generated and when you touch them, it will move the camera to the center of the new room and put you infront of the door you came out of. All rooms are equal sizes so you always move the same amount. Each door has a randomized variable telling it which side of the room it is on. I need a way for the player object to get that variable from that specific door. Thank you for help.
(2D, Javascript)

Code (JavaScript):

1. function OnTriggerEnter2D (obj : Collider2D) {
2.     var name = obj.gameObject.name;
3. if(name == "door") {
4.    
5.    
6.     }
7.     }
8.    

 

Use GetComponent to find a script on a object, and then access the variable on the script.

Code (CSharp):

1. function OnTriggerEnter2D (obj : Collider2D) {
2.     var name = obj.gameObject.name;
3. if(name == "door") {
4.    obj.gameObject.GetComponent(scriptName).variableName
5.  
6.     }
7.     }
