Trigger animation using script on separate box collider

Question

I'm trying to do something that I thought would be very simple, but it's proving to be very difficult to figure out.

I have a box collider with 'Is Trigger' enabled, and I want to add a script to this trigger box to play an animation on another game object. This game object has an animation on it, which was created in unity. I am using unity 4.3.4.

Example:

-Walk through underground tunnel where a collider box is entered.

-On entering the collider box a train animation is triggered

-Train drives down platform and stops (as animated)

Thanks for your input, this worked for me. Just applied this script to the trigger box and dragged in the corresponding game objects.

 var  Train: GameObject; //object to be animated
 var TrainAnimation : String; //animation to be played
        
 function OnTriggerEnter(Collision){
 Train.animation.Play(TrainAnimation);
 }

After this I was getting a message about marking the animation as legacy. To do this with a unity made animation I found out I had to follow these steps.

Switch the Inspector panel to a debug mode (3 stripes in a right top corner, near lock icon)
Set the animation type to a "1"
Switch the Inspector panel to a normal mode

I haven't used animations before in unity yet but I think this will help you to get started.

So you have a Box that has a script. When you walk through that "Box" which is a trigger it will make the animation play. I think something like this will help you.

The Train Script:

 using UnityEngine;
 using System.Collections;
     public class TrainScript: MonoBehaviour {
     
         public bool PlayAnimation = false;
     
 
         void Start () {    
         
         }
         
 
         void Update () {
             if(PlayAnimation){
             // Whatever function or code you write to start the animation
             // or however you want to do the animation}
         }
         
         
     }

This Box Script :

 using UnityEngine;
 using System.Collections;
 
 public class Box: MonoBehaviour {
        // Make sure you have the Train Object
     public GameObject Train;
       // The Script of the train;
     private TrainScript trainscript;
 
      
     void Start () {    
                 // This will get the script and set the trainscript
         trainscript= Train.GetComponent("TrainScript ") as TrainScript ;
     }
     
     // Update is called once per frame
     void Update () {
         
     }
     
     void OnTriggerEnter(Collider collision){
         if(collision.gameObject.tag == "Your Character's Tag"){
             trainscript.PlayAnimation = true;
         }
     }
 }

Now what this should do is, when your mainplayer/character enters the Box/Trigger it will edit the bool inside the train's script to make it true. Then inside of the trainscript you will have a case if that bool is true it will make the animation run/play.
