How to do it...

This recipe entails adding changes to our Agent class.

1. Go to the Agent class.
2. Add a member variable for storing the rigid body component's reference:

private Rigidbody aRigidBody; 

3. Get the reference to the rigid body component in the Start function:

aRigidBody = GetComponent<Rigidbody>(); 

4. Implement a function for transforming an orientation value to a vector:

public Vector3 OriToVec(float orientation) 
{ 
  Vector3 vector = Vector3.zero; 
  vector.x = Mathf.Sin(orientation * Mathf.Deg2Rad) * 1.0f; 
  vector.z = Mathf.Cos(orientation * Mathf.Deg2Rad) * 1.0f; 
  return vector.normalized; 
} 

5. Add the following two lines at the beginning of the Update function:

public virtual void Update () { if (aRigidBody == null) return; // ... ...
