Lerp Smooth Rotation

Questions & Answers
1

I want to smothly rotate an object to a specific location so I coded this:

#pragma strict

var turnSpeed : float = 80;
var left = 55.0;
var right = 130.0;
var center = transform.rotation;


function Update () {

var rot = transform.rotation.eulerAngles.y;

//rotate the object left.
	if(Input.GetKey("a") && rot >= left)
        transform.Rotate(Vector3.forward, -turnSpeed * Time.deltaTime);

//rotate the object right.
	else if(Input.GetKey("d") && rot <= right)
        transform.Rotate(Vector3.forward, turnSpeed * Time.deltaTime);

//brink the object back to its starting possition... Or at least that's what I want it to do!
	else {
		transform.rotation = Quaternion.Lerp(transform.rotation, center, turnSpeed * Time.deltaTime);
	}

}

I get this error “You are not allowed to call this function when declaring a variable. Move it to the line after without a variable declaration.”

And when I go to play mode I get a couple more errors!

Any help?

Variables should only be declared outside functions; running code to initialize them should be done in Awake or Start.

var center : Quaternion;

function Start () {
	center = transform.rotation;
}

Also you should use KeyCode enums for GetKey rather than strings (strings are slower and more error-prone).
