I have an NPC with a character controller that roams around. It's important that I know its velocity so that the right animation clip will be playing. I'm getting an error in my program where my model is not moving, but the velocity is ~10, so the "walk" animation is playing. I should note that the NPC is currently being purposely blocked by my character, so the NPC's Move() function is being called, but it's not actually moving. As I said, I need this functionality in order to have the right animation clip play.

Here is the NPC's move function:

public void MoveTowards(Vector3 position)
{
    Vector3 direction = position - transform.position;
    direction.y = 0;

    if (direction.magnitude < 0.2F)
    {
        if (num == (waypoints.Length - 1)) num = 0;
        else num++;
        return;
    }

    // Rotate towards the target
    transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(direction), rotationSpeed * Time.deltaTime);
    transform.eulerAngles = new Vector3(0, transform.eulerAngles.y, 0);

    // Modify speed so we slow down when we are not facing the target
    Vector3 forward = transform.TransformDirection(Vector3.forward);
    float speedModifier = Vector3.Dot(forward, direction.normalized);
    speedModifier = Mathf.Clamp01(speedModifier);

    // Move the character
    direction = forward * speed * speedModifier;
    controller.SimpleMove(direction);
}

And here's is the block of code that handles animation, inside the Update() method:

if (gameObject.GetComponent<CharacterController>().velocity.magnitude > 1)
    {
        animation.CrossFade("walk");
    }
    else
    {
        animation.CrossFade("idle");
    }

Can anyone help?
