Is the for loop mandatory? You can easily do what you are describing without a for loop.

As for how for loops work, I would recommend reading the following page, as there is no use in me rewriting what has already been written:

The for loop is not mandatory. Just looking for the best solution shoot a raycast at the player in 2 second time increments. Any ideas?

I know i can use InvokeRepeating but is there another way to do this loop cycle? maybe in a corontine? or another way?

Something like this would probably work:

 public float timeBetweenShots = 2f;
 private float lastShotTime = 0;
 
 private void Update() {
    //check to see if it is time to shoot
    if (Time.time - lastShotTime > timeBetweenShots) {
       //setup the ray however you need, this is just an example
       Ray myRay = Camera.mainCamera.ScreenPointToRay(Input.mousePosition);
       RaycastHit myRayHit;

       //do the raycast
       if (Physics.Raycast(myRay, out myRayHit) {
          //put code here to damage the player
       }
 
       //set 'lastShotTime' to the current time
       lastShotTime = Time.time;
    }
 }

Hope this helps. Does this answer your question?

Im not at home right now but here is a rough answer that i came up with...

 var shotTimer: float;    
 var DamagePerSecond = 1;
 var OpenFire = false;
 
 function Update()
 {
     shotTimer = Time.deltaTime * DamagePerSecond;
     
     if(shotTimer > 1)
     {
         OpenFire = true;
         shotTimer = 0;
     }
     
     else
     OpenFire = false;
     
     if(OpenFire == true)
     {
         //Shoot Raycast at Player 
     
 //        if(Raycvast hits player collider)
 //        {
 //            player.playerHealth -= 1;
 //        }
     }
 }

This is rough and not exactly how i did it pertaining to my project because i used triggers to register to see if enemy is within a certain distance. But here is a revised answer!
