It says my Update() can not be a coroutine what should I Do to fix it

#pragma strict

var moveUp : KeyCode;
var moveDown : KeyCode;

var speed : float = 15;
function ResetPlayers ()
{
transform.position.y = 0;

 }

function Update ()
{
if (“ResetPlayers”) yield WaitForSeconds (4);
}
if (Input.GetKey(moveUp))

{
	rigidbody2D.velocity.y = speed;
}

if (Input.GetKey(moveDown))
{
	rigidbody2D.velocity.y = speed *-1;
}
else
{
	rigidbody2D.velocity.y = 0;
}

In the function OnEnable, start your update coroutine and stop it in OnDisable.

Your update coroutine should never end and be like :

IEnumerator MyUpdate()
{
  while(true)
  {
    // your code
    yield return null;
  }
}

This code sample is C#. Use the javascript equivalent if you need it.

But most important, what is the point of having a coroutine to manage an update?

Tourist was showing you in C# that you could just create a function that does your yielding for you. So you could have a external function that would reset the players

playersAreReady : bool = true;

function Update(){
   if(playersAreReady){
     //your code here. 
   }
}

function ResetPlayers(){
   playersAreReady = false;
   yield WaitForSeconds(4);
   playersAreReady = true; 
}

Then from somwhere else you can just reset players like this

ResetPlayers();
