'Collision' does not contain a definition for 'contacts'

started trying out OnCollisionEnter with the example code from here http://docs.unity3d.com/Documentation/ScriptReference/Collision-contacts.html

this piece of code

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class qwe : MonoBehaviour
6. {
7.     void OnCollisionEnter(Collision asd)
8.     {
9.         ContactPoint zxc = asd.contacts[0];
10.     }
11. }

gives this error

error CS1061: Type `Collision' does not contain a definition for `contacts' and no extension method `contacts' of type `Collision' could be found (are you missing a using directive or an assembly reference?)

what am i missing

 

Which version of Unity are you using?

 

Don't call your classes the same thing as Unity classes. Any time you get an error about something that's "missing", it's because you have a collision between a Unity class and your own class, and your own class doesn't have the same stuff in it. (Although if you made a contacts property for your Collision class, you wouldn't get the error, but then it still wouldn't work right.)

4.3.2f1

no matter what i call my class it wont recognize contacts

 

It's not that class...you have another class elsewhere called Collision.
