IndexOutOfRangeException: Index was outside the bounds of the array.
Portal.OnCollide (UnityEngine.Collider2D coll) (at Assets/scripts/Portal.cs:12)
Collidable.Update () (at Assets/scripts/Collidable.cs:25)

here is my code:

**Portal.cs

public class Portal : Collidable
{
    public string[] sceneNames;

    protected override void OnCollide(Collider2D coll)     
    {
        if (coll.name == "Player")
        {
            // teleport player
            string sceneName = sceneNames[Random.Range(0, sceneNames.Length)];
            UnityEngine.SceneManagement.SceneManager.LoadScene(sceneName);
        }
    }

}```

**Collidable.cs**

```using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Collidable : MonoBehaviour
{
    public ContactFilter2D filter;
    private BoxCollider2D boxCollider;
    private Collider2D[] hits = new Collider2D[10];

    protected virtual void Start()
    {
        boxCollider = GetComponent<BoxCollider2D>();
    }

    protected virtual void Update()
    {
        // collision stuff
        boxCollider.OverlapCollider(filter, hits);
        for (int i = 0; i < hits.Length; i++)
        {
            if (hits[i] == null)
                continue;

            OnCollide(hits[i]);

            hits[i] = null;
        }
    }

    protected virtual void OnCollide(Collider2D coll)
    {
        Debug.Log(coll.name);
    }
}```

You will get that error if your sceneNames array has size of 0

[errant dawn]

alright so in line 12 collum 56/57 the 0 in there has to be removed?

[rose matrix]

no, in your inspector you need to populate the array

the code is fine

[errant dawn]

alright i got it like this do i just write the scene name in the element?

[rose matrix]

add all the scene names you wish to randomly choose from there, yes

[errant dawn]

Scene 'Dungeon1' couldn't be loaded because it has not been added to the build settings or the AssetBundle has not been loaded.
To add a scene to the build settings use the menu File->Build Settings...
UnityEngine.SceneManagement.SceneManager:LoadScene (string)
Portal:OnCollide (UnityEngine.Collider2D) (at Assets/scripts/Portal.cs:13)
Collidable:Update () (at Assets/scripts/Collidable.cs:25)

now gives me this error ^^

oh wait

i think i know how to fix this

[rose matrix]

yep it tells you
