I'm missing a method to link up character control with animations which are triggered through my GUI.

I found a helpful script which triggers animation through GUI buttons here:

http://answers.unity3d.com/questions/18382/i-need-help-assigning-animation-clips-to-gui-buttons

var model : GameObject;

function OnGUI () { 

  //background box 
  GUI.Box (Rect (10,130,100,90), "Controls");

  //Make first button
  if (GUI.Button (Rect(20,160,80,20),  "Arm")){
    model.animation.Play("raise arms", PlayMode.StopAll);
  } 

  //Make second button
  if (GUI.Button (Rect(20,190,80,20),  "Neck")){ 
    model.animation.Play("raise neck", PlayMode.StopAll);
  } 
}

I'm attempting to get this to work with something similar to the "SampleMoveScript.js"

var speed = 3.0;
var rotatationSpeed = 200.0;
private var curSpeed = 0.0;



function Update () 
{ 
    if  (!animation.IsPlaying ("startUp") && !animation.IsPlaying ("armDrillAnimation04"))
        {

    // Rotate around y-axis
    var newRotation = Input.GetAxis("Horizontal") * rotatationSpeed;
    transform.Rotate(0, newRotation * Time.deltaTime, 0);

    // Calculate speed
    var newSpeed = Input.GetAxis("Vertical") * speed;
    if (Input.GetKey("left shift"))
        newSpeed *= 1.5;

    // Move the controller
    var controller : CharacterController = GetComponent (CharacterController);
    var forward = transform.TransformDirection(Vector3.forward);
    controller.SimpleMove(forward * newSpeed);

    // Update the speed in the Animation script
    SendMessage("SetCurrentSpeed", newSpeed, SendMessageOptions.DontRequireReceiver);
    SendMessage("SetCurrentLean", Input.GetAxis("Horizontal"), SendMessageOptions.DontRequireReceiver);
        }
}

@script RequireComponent (CharacterController)
