how to play sound clip when near an AI?

Its probably pretty simple, but I'm just wondering what function you would use for this.

 

Find the distance from your AI object and then play the sound.

Code (csharp):

1.  
2. float dist = Vector3.Distance(transform.position, ai.transform.position);
3.  
4. if (dist <= someValue)
5. {
6.    // Play the sound
7. }
8.  

I assume ai is a GameObject that stores the object you call AI.
