I need Help With a Speed up script

Question

I want my character to have a speed up boost when ever he inputs left shift but it only lasts for a few seconds and cant be used again for 10 seconds. There is also a Gui texture that is supposed to appear when its ready to be used.

Here is the script i used but the Gui texture does not work right.

var speed= 40.0; var rotateSpeed = 3.0; var runningSpeed= 10.0; var strafeSpeed = 40; var savedTime=0; var GUI1 : GUITexture;

function Update () {

     var seconds : int = Time.time;
     var oddeven = (seconds % 2);
         
     if(oddeven)
     {
         Shoot(seconds);
     }

}

function Start(){ GUI1.enabled = false; }

function Shoot(seconds){

     GUI1.enabled = true;

if (Input.GetKey("left shift")){ if(seconds!=savedTime){ var controller : CharacterController = GetComponent(CharacterController); //transform.Rotate(0, Input.GetAxis ("Horizontal") rotateSpeed, 0); var forward = transform.TransformDirection(Vector3.forward); var curSpeed = speed Input.GetAxis ("Vertical"); controller.SimpleMove(forward * curSpeed); } } }

Here is an option:

 var speed : float = 40.0; 
 var rotateSpeed : float = 3.0; 
 var runningSpeed : float = 10.0; 
 var strafeSpeed : float = 40; 
 var GUI1 : GUITexture;
 
 var speedUpTime : float = 5; // How long do you have a speed boost
 var speedUpFactor : float = 1;
 var controller : CharacterController; 
 
 function Start()
 { 
     controller = GetComponent(CharacterController); 
      GUI1.enabled = true; 
 }
 
 function Update () 
 {
     if ( GUI1.enabled && Input.GetKey("left shift") )
     {
         StartCoroutine(EnableShiftAfterAWhile());
         StartCoroutine(SpeedUpForAWhile());
     }
 
     // Put here you movement processing
     transform.Rotate(0, Input.GetAxis ("Horizontal") * rotateSpeed, 0); 
     var forward = transform.TransformDirection(Vector3.forward); 
     // You current speed should be effected by the speedFactor
     var curSpeed = speed * Input.GetAxis ("Vertical") * speedUpFactor; 
     controller.SimpleMove(forward * curSpeed); 
 }
 
 function SpeedUpForAWhile()
 {
     speedUpFactor = 2; // Move twice as fast
 
     yield WaitForSeconds(speedUpTime);
 
     speedUpFactor = 1; // Regular move speed
 }
 
 function EnableShiftAfterAWhile()
 {
     GUI1.enabled = false;
 
     yield WaitForSeconds(10);
 
     // Once the time wait time has passed you can re-enable the gui (and shift...)
 
     GUI1.enabled = true;
 }
