Enemy stop moving when stared at

I thought there was a similar question to this a while back, and after searching it was yours. http://answers.unity3d.com/questions/273809/need-an-enemy-script-that-makes-him-wander-and-det.html

I find this interesting, as the concept re$$anonymous$$ds me of the statues in Dr Who =]

It sounds like you have thought about it and made start. The idea is ok, having a invisible block that basically lives in the player view. You are soo close, all you need to do is add an OnTriggerEnter or OnCollisionEnter on the monster script to say freeze someone's looking, then OnTriggerExit/OnCollisionExit to say ok no-one's looking so move.

EDIT : if you are just starting out, do all the $$anonymous$$i-projects on unity3dstudent (they are about 5 $$anonymous$$utes each) : http://www.unity3dstudent.com/category/modules/beginner/

it's in reverse order, so scroll down and start at Beginner B00 – Adding $$anonymous$$ass / Gravity with Rigidbodies

I checked out the video, and other links. What would I need to add to make it disable a script temporarily once the trigger cube is over the other collider?

You want to disable the movement, yes, but just makes things more complicated for what you want to do (even though disabling the script is possible). Ins$$anonymous$$d, have a boolean on the monster script and check it before the movement, and use OnTriggerEnter and Exit to toggle this boolean. e.g.

 var isSeen : boolean = false;

 function Update() 
 {
     if (!isSeen) // ! means if (isSeen == false)
     {
         $$anonymous$$ove$$anonymous$$onster();
     }
 }

 function OnTriggerEnter( other : Collider ) 
 {
     if (other.tag == "Player")
     {
         isSeen = true;
     }
 }

 function OnTriggerExit( other : Collider ) 
 {
     if (other.tag == "Player")
     {
         isSeen = false;
     }
 }

Is "$$anonymous$$ove$$anonymous$$onster" the script that makes him follow you?
