I want to make my enemy character to get a random rotation, then move for about 3 sec, then stay get a new rotation and move again. And keep doing that until the player comes in range.

Here is my code:

   function Idle()
{
    while(true)
    {
        if(dist > awareDist)
        {
           randRotation();
           yield WaitForSeconds(5);
           walkRandom();
           yield WaitForSeconds(5);
        }
    }   
}

function randRotation()
{
    transform.rotation =  Quaternion.AngleAxis(Random.Range(-40,40), Vector3.up);
}

function walkRandom()
{
    var forward : Vector3 = transform.TransformDirection(Vector3.forward);
    var controller : CharacterController = GetComponent(CharacterController);
    controller.SimpleMove(forward * speed); 
}

The Idle function is called from Start. Animations will be added. dist is the distance to the palyer.

Get a switch statement, and each case, have it do a certain action, maybe 1,3,6,8 all rotate accordingly; 10,30,90,130 degrees, then 2 and 7 move the object forward accordingly; 5 units, 10 units, and numbers 4 and 9 just pause for the 2 second yield in between...

Or you could make multiple functions, randomly chooses a function, and that function has a script that uses coroutines that make the character return to its original spot as if it doesn't it could fall off the cliff... lol

But yeah, 3 ways to go about it.
