Animations not playing (issue with scripts)

Questions & Answers
1

I’m following scripting from a book. I don’t have all the animations made at the moment, yet I follow the scripts right from the book. Despite (nearly) completing the scripts. None of the animations are playing when I press any of the keys (and I have the animation clips attached to the prefab).

Am I doing something wrong with these scripts?
var runSpeed = 3.0;
var jumpSpeed = 8.0;
var gravity = 20.0;
var rotateSpeed = 4.0;
var crouchSpeed = 0.5;

var isControllable : boolean = true;

//Private, helper variables
private var moveDirection = Vector3.zero;
private var grounded : boolean = false;
private var moveHorz = 0.0;
private var normalHeight = 2.0;
private var crouchHeight = 1.7;
private var rotateDirection = Vector3.zero;

private var isCrouching : boolean = false;
private var isRunning : boolean = false;

//Cache controller so we only have to find it once
var controller : CharacterController;
	controller = GetComponent(CharacterController);
var MoaliaStatus : Moalia_Status;
MoaliaStatus = GetComponent(Moalia_Status);

//Move the controller during the fixed frame updates
function FixedUpdate ()
{
	if(!isControllable)
		Input.ResetInputAxes ();
	else
	{
		if(grounded) 
		{
			//Since we're touching something solid,
			//such as the ground, allow movement
			//Calculate movement directly from input axes
			moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
			moveDirection = transform.TransformDirection(moveDirection);
			moveDirection *= walkSpeed;
			moveDirection.y -= gravity * Time.deltaTime;
			
			//Find rotation based upon axes if need to turn
			moveHorz = Input.GetAxis("Horizontal");
			if (moveHorz > 0)	//Right turn
				rotateDirection = new Vector3(0, 1, 0);
			else if (moveHorz < 0)	//Left turn
				rotateDirection = new Vector3(0, -1, 0);
			else	//not turning
				rotateDirection = new Vector3(0, 0, 0);
			
			//Jump controls	
			if(Input.GetButton("Jump"))
			{
				moveDirection.y = jumpSpeed;
			}
		
			//Aplly any boosted speed
			if(Input.GetButton("Run"))
			{
				isRunning = true;
				if(MoaliaStatus)
				{
					moveDirection *= runSpeed;
					MoaliaStatus.stamina -= MoaliaStatus.runUsage * Time.deltaTime;
					isRunning = true;
				}
			}
		}
	
		//Crouch the controller
		if(Input.GetButton("Crouch"))
		{
			controller.height = crouchHeight;
			controller.center.y = controller.height/2 + .25;
			moveDirection *= crouchSpeed;
			isCrouching = true;
		}
		
		if(Input.GetButtonUp("Crouch"))
		{
			//Reset height and center after ducks
			controller.height = normalHeight;
			controller.center.y = controller.height/2;
			isCrouching = false;
		}
		
		if(Input.GetButtonUp("Run"))
		{
			isRunning = false;
		}
		
		//Apply gravity to end jump, enable falling, and make sure he's touching the ground
		moveDirection.y -=gravity * Time.deltaTime;
		
		//Move and rotate the controller
		var flags = controller.Move(moveDirection * Time.deltaTime);
		controller.transform.Rotate(rotateDirection * Time.deltaTime, rotateSpeed);
		grounded = ((flags & CollisionFlags.CollidedBelow) != 0);
	}

Update: forgot to attach the script. Now I have a load of these errors:

“MissingMethodExceptioni: Moalai_Controller.IsRunning
Boo.Lang.Runtime.Dynamicdispatching.MedfthodDispacherFactory.ProduceExtensionDispacher ()” (@ line 32, Moalia_Animation)

Looks like your first script should have had something like:

function IsRunning ()
{
  return IsRunning;
}
