How do i make multiple waypoints?

Question

Hi guys i manged to make one way point that is attached to a target and it tells the distance between the target and the player

Now im trying to add 5 more and thats what i cant figure out. So im trying to make 6 way points with each target telling the player the distance between the player and target

This is my code

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;

public class Waypoint : MonoBehaviour

{

private Image iconImg;

private Text distanceText;

 public Transform Player;
 public Transform Target;
 public Camera Camera;

 public float closeDistance;


 // Update is called once per frame
 private void Start()
 {
     iconImg = GetComponent<Image>();
     distanceText = GetComponentInChildren<Text>();
 }

 private void Update()
 {
     if(Target != null)
     {
         GetDistance();
         CheckOnScreen();
     }
 }

 private void GetDistance()
 {
     float dist = Vector3.Distance(Player.position, Target.position);
     distanceText.text = dist.ToString("f1") + "m";
     
     if(dist < closeDistance)
     {
         Destroy(gameObject);
     }

 }

 private void CheckOnScreen()
 {
     float thing = Vector3.Dot((Target.position - Camera.transform.position).normalized, Camera.transform.forward);

     if(thing <= 0)
     {
         ToggleUI(false);
     }
     else
     {
         ToggleUI(true);
         transform.position = Camera.WorldToScreenPoint(Target.position);
     }
 }

 private void ToggleUI(bool _value)
 {
     iconImg.enabled = _value;
     distanceText.enabled = _value;
 }

}

Thanks in advance

Make an Array of GameObjects for your targets

 public Transform[] Target = new Transform[6];  //Make an Array for your targets 
  public Camera Camera;
  public float closeDistance;
  // Update is called once per frame
  private void Start()
  {
      iconImg = GetComponent<Image>();
      distanceText = GetComponentInChildren<Text>();
  }
  private void Update()
  {
 int targetCounter = 0;  //Loop through the Array and check if Transform is not null
 foreach(var target in Target){
 if(target != null){
 targetCounter++;
 }
 }
      if(targetCounter > 0)  //Check if Array is larger than 0
      {
          GetDistance();
          CheckOnScreen();
      } else {
      Debug.Log("No more targets");   //Array Length is 0
   }
  }
  private void GetDistance()
  {
 foreach(var target in Target){  //Loop through the Array and check distance tothe waypoints
      float dist = Vector3.Distance(Player.position, target.position);
      distanceText.text = dist.ToString("f1") + "m";
      
      if(dist < closeDistance)
      {
          Destroy(gameObject); //If you want to remove the waypoints instead of the gameobject you have to set target to null
      }
  }
 }
 
  private void CheckOnScreen()
  {
 foreach(var target in Target){ //Loop through the array and check if target is on screen
      float thing = Vector3.Dot((target.position - Camera.transform.position).normalized, Camera.transform.forward);
      if(thing <= 0)
      {
          ToggleUI(false);
      }
      else
      {
          ToggleUI(true);
          transform.position = Camera.WorldToScreenPoint(target.position);
      }
  }
 }
 
  private void ToggleUI(bool _value)
  {
      iconImg.enabled = _value;
      distanceText.enabled = _value;
  }
 }
