How do I get a function to recognize a variable in function Update()

//SCRIPT GOAL
//every 10 seconds pick a location,move to it and then patrol

var ready : boolean;
var speed : float;
var timer : float;
var patrolTimer : float = 10; //how long should it patrol for


//Targets
var target1 : Transform;
var target2 : Transform;
var target3 : Transform;
var target4 : Transform;



function Update (){

if(ready == true){
patrolTimer = 10;
//pick location
var chooseNext = Random.Range(0,2);
//countdown to move 
timer -= Time.deltaTime;
    if(timer <= 0){
    ready = false;
    }
}

if(ready == false){
Move();
}

}


function Move(){

var step = speed * Time.deltaTime;

if(chooseNext == 0){
Debug.Log("moving");

// move towards target1
		transform.position = Vector3.MoveTowards(transform.position, target1.position, step);
		if(this.gameObject.transform.position == target1.position){
		Patrol();
		Debug.Log("Reached destination 1");
		}
}
		
		
		if(chooseNext == 1){
Debug.Log("moving");

// move towards target1
		transform.position = Vector3.MoveTowards(transform.position, target2.position, step);
		if(this.gameObject.transform.position == target2.position){
		Patrol();
		Debug.Log("Reached destination 2");
		}
		}
		
		if(chooseNext == 2){
Debug.Log("moving");

// move towards target1
		transform.position = Vector3.MoveTowards(transform.position, target3.position, step);
		if(this.gameObject.transform.position == target3.position){
		Patrol();
		Debug.Log("Reached destination 3 ");
		}
		
}
}



function Patrol(){
//patrolling
Debug.Log("patrolling");
patrolTimer -= Time.deltaTime;

  if(patrolTimer <=0){
  //finished patrolling
		     ready = true;
		     Timer = 1;
		     Debug.Log("Ready to move");
		     
		   }
}

Debugger keeps giving unknown identifier : chooseNext.
I want chooseNext to change everytime ready becomes true so I can’t put it into move() otherwise the ready = false function would keep calling it andd the object would spaz out deciding where to go.
How can I get the function Move() section to get the chooseNext variable from update().

Thanks in advance

You make it a “field” instead of a local variable, i.e. you move it outside the Update() like your other variables. Then it’s visible in the whole script.

var chooseNext : int;
 
 function Update ()
 {
	 if(ready == true)
	 {
		 patrolTimer = 10;
		 //pick location
		 chooseNext = Random.Range(0,2);
		 //countdown to move 
		 timer -= Time.deltaTime;
	     if(timer <= 0)
	     {
	    	 ready = false;
	     }
	 }

     if(ready == false)
	 {
	 	Move();
	 }
 }

Also, I don’t know what exactly you want to happen in this script and i don’t know what the start values for time and ready are but to me it looks like that when Patrol() finishes for the first time, the next entire second you spend in the if(ready == true) randomising the chooseNext etc…
