Im Writting a Script that will generate a list of connect waypoints but the only thing is im stuck with the last peice of code…

this is my code

#pragma strict

@script ExecuteInEditMode()


/************************************************************************************************************/
// Simple Waypoint Script.
// Author: Harley Urquhart
// Version: 1
/************************************************************************************************************/
//Notes
//This Requires that at least one other waypoint is included as a link
//Behaviours can then be made 
/************************************************************************************************************/
//Variables
var Links : Transform[];
/************************************************************************************************************/
function Awake(){
	//test for errors
	if (Links.Length <1){
		//display an error and the name of the waypoint
		Debug.LogError("Please assign at least one object to the array of waypoints in the editor for: " + gameObject.name);
	}
	if(gameObject.CompareTag("Untagged")){
		//	Set the Tag Immediately if the player forgot to tag the Waypoint Prefab
		gameObject.tag = "Waypoint";
	}
}

function Start () {
	//make the object invisible
	renderer.enabled = false;
	//turn off collisions
	collider.enabled = false;
}

function Update(){
	// draw a ray to visualise the path between Two way points(minimum)
	// create a forloop
	
	//instead of manually adding linked waypoints 
	//find waypoins that are not obscured by any colliders 
	//then link them together by adding that waypoint to the links array
	
	// Find all game objects with tag Waypoint
	var Waypoints : GameObject[];//array of all tagged Gameobjects
	Waypoints = GameObject.FindGameObjectsWithTag("Waypoint"); 
	var position = transform.position; //
	//find waypoints that are not blocked by a collider.
	for (var waypoint : GameObject in Waypoints)  { 
		//cast out a ray
        var hit : RaycastHit;
        if (Physics.Raycast (position, waypoint.transform.position, hit)) {
            
        }
	}	
	
	for (var x = 0; x < Links.Length;x++){
		//iterate through all the coonected waypoints and cast rays out
		Debug.DrawLine(transform.position, Links[x].position,Color.red);
	}
	
}

function OnDrawGizmos () {
	Gizmos.DrawIcon (transform.position, "Light Gizmo.tiff", true);
}

i just need help at line 53 to inset the correct code here

Seems like a simple if/else statement to me, at least in this particular script.

    if (Physics.Raycast (position, waypoint.transform.position, hit)) {
      // raycast did hit
    }
    else {
      // raycast didn't hit
    }
