using yield WaitForSeconds(3); in function update

Questions & Answers
1

I need to use yield WaitForSeconds(3); in the function update but can’t how else could you get the same effect?

var cubeSpeed : float = 0.01;
var cubeMoving : boolean = true;
function Update ()
{
	
	if(cubeMoving)
	{
		transform.Translate(0,cubeSpeed,0);
	}
		
	if(transform.position.y >= 10) 
	{
			
		cubeMoving = false;
		gameObject.renderer.material.color = Color.red;
		//need to use "yield WaitForSeconds(3);" here
		gameObject.renderer.material.color = Color.green;
	}	
	
}

var cubeSpeed : float = 0.01;
var cubeMoving : boolean = true;
private var alreadyWaiting : boolean =false;
function Update ()
{

    if(cubeMoving)
    {
       transform.Translate(0,cubeSpeed,0);
    }
 
    if(transform.position.y >= 10 && !alreadyWaiting ) 
    {
 
       cubeMoving = false;
       Wait(3);
    }  
 
}

function Wait(time : float)
{
    alreadyWaiting = true;
    Debug.Log("time started");
    gameObject.renderer.material.color = Color.red;
    yield WaitForSeconds(time);
    gameObject.renderer.material.color = Color.green;
    Debug.Log("time ended");
    alreadyWaiting = false;
}

I added on Kral’s answer, since his was incomplete.
You can call the function and lock it (prevent to call) untill the given time passes.

var canCallFunction: boolean = true;
 
function Wait(time : float)
{
  canCallFunction= false;
  Debug.Log("time started");
  yield new WaitForSeconds(time);
  Debug.Log("time ended");
  canCallFunction= true;
}
 
function Update()
{
  if(canCallFunction)
     Wait(3);
}

Hope this helps
