Question by geryc123 · Jan 20, 2014 at 01:22 AM · function updatescroll view

How to turn this script?

I have a script to scroll:

 var speed = 2.2;
 var crawling = false;
 
 function Start()
 {
 
 Screen.showCursor = true;
   
  }
 
 function Update ()
 {
     if (!crawling)
         return;
     transform.Translate(Vector3.up * Time.deltaTime * speed);
     if (gameObject.transform.position.y > .8)
     {
         crawling = true;
     }
 }

And I have one questions, how to do after 10 seconds began to scroll in down ?

I have tried:

 var speed = 2.2;
 var crawling = false;
 
 function Start()
 {
 
 Screen.showCursor = true;
   
  }
 
 function Update ()
 {
     if (!crawling)
         return;
     transform.Translate(Vector3.up * Time.deltaTime * speed);
     if (gameObject.transform.position.y > .8)
     {
         crawling = true;
     }
     
     yield WaitForSeconds(10);
     
     
      if (!crawling)
         return;
     transform.Translate(Vector3.down * Time.deltaTime * speed);
     if (gameObject.transform.position.y > .8)
     {
         crawling = true;
     }
     
     
 }

but this is not work :/

You cannot yield in Update(). I might approach this problem differently, but from where you are now, consider using Invoke(). You could do:

 var speed = 2.2;
 var crawling = false;
  
 function Start() 
 {
     Screen.showCursor = true;
     Invoke("Reverse", 10.0);
  }
 
 function Reverse()
 {
     speed = -speed;
 }
  
 
 
 function Update ()
 {
       if (!crawling)
              return;
        transform.Translate(Vector3.up * Time.deltaTime * speed);
        if (gameObject.transform.position.y > .8)
        {
             crawling = true;
         }
   }

Sorry about the crawling. I mis-read your script.
