Moving spawned enemies randomly towards several pre-defined positions

Questions & Answers

Hi everyone, I am new to Unity so it’s probably something simple, but so far could not find a solution anywhere.

I am creating a game where I spawn a new enemy every 2 seconds. Now, I want that each newly spawned enemy will go to 1 possible position out of 600. The final result should be that each enemy will go randomly to one to the predefined spots on the screen.

I can’t drag the spots in the inspector to the array because Unity does not let me. And I also tried adding a foreach before, but it did not work as well. What am I doing wrong? Thanks!

I tried:

private Rigidbody2D rb;
    private GameObject[] spots;
    private float moveSpeed;
    private Vector3 directionToPlayer;
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        spots = GameObject.FindGameObjectsWithTag("spot");
        moveSpeed = 2f;
  
    }


    private void FixedUpdate()
    {
        MoveEnemy();
    }


   private void MoveEnemy()
    {
        int rand;
        rand = Random.Range(0,spots.Length);
        directionToPlayer = (spots[rand].transform.position - transform.position).normalized;
        rb.velocity = new Vector2(directionToPlayer.x, directionToPlayer.y) * moveSpeed;
    }

Thank you very much!

You have all your variables in private, replace them with public.

public Rigidbody2D rb;
public GameObject spots;
