#pragma strict

//Loading effect

public var loading : boolean = false;

var loadingTexture : Texture;

var size : float = 70.0;

private var rotAngle : float = 0.0;

var rotSpeed : float = 300.0;

function Update ()
{

if(loading)
    {

    	rotAngle += rotSpeed * Time.deltaTime;
    }	

}

function OnGUI()
{

    if(loading)
    {
	var pivot : Vector2 = Vector2(Screen.width/2, Screen.height/2);

	GUIUtility.RotateAroundPivot(rotAngle%360,pivot);

	GUI.DrawTexture(Rect ((Screen.width - size)/2 , (Screen.height 
            - size)/2, size, size), loadingTexture);
