Setting off animation with trigger

Im trying to figure out how to make doors open when a trigger is hit. So i shoot a button and it opens one door. Then a different button sets off a different door animation. If not willing to tell me how....could you at least point me in the direction of a good tut. Thanks.

If you have door animations then use for the button something like

var door : GameObject;

function HitByBullet() {
 door.animation.play("open")
}

When you determine that the button has been hit, call the HitByBullet function.

If you haven't figured out how to tell if the button was hit yet, check the scripting reference for OnTriggerEnter, OnCollisionEnter, and Physics.Raycast; one of those should make you happy.
