animation switching

I am trying to play another animation by accessing another animatorcontroller.How would i correct this script?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class ActivateAnimation : MonoBehaviour
5. {
6.     void OnCollisionEnter (Collision col)
7.     {
8.         if(col.gameObject.name == "prop_powerCube")
9.         {
10.             anim = GetComponent<Animator>();
11.          
12.          
13.             anim.runtimeAnimatorController = AnimationforPioyu ;
14.          
15.         }
16.     }
17. }

 

I don't know much about animation, but from your script i can see that the variable anim is not declared but is used.
What is AnimationforPioyu ?
Also is good practice to not use GetComponent after initialization.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. public class ActivateAnimation : MonoBehaviour
4. {
5.     Animator anim;
6.  
7.      void Start()
8.         {
9.              anim=GetComponent<Animator>();
10.         }
11.  
12.     void OnCollisionEnter (Collision col)
13.     {
14.         if(col.gameObject.name == "prop_powerCube")
15.         {
16.      
17.      
18.             anim.runtimeAnimatorController = AnimationforPioyu ;
19.      
20.         }
21.     }
22. }

 

AnimationforPioyu is a animatorcontroller.
