How to remove elements from string lists?

I’m trying to make a .io game, and I’m trying to make it so that when “players” spawn and choose a random username, the username element they just chose gets removed from the list to prevent other “players” from using the same username. Here’s a image of the code (It’s for testing, but still):

First thing is, you are declaring ‘names’ as an Array, not a List, and you are right assuming it should be a List :slight_smile:
Also, you don’t need the for loop because you already know the index of the string you want to delete.
A possible solution could be:

// Define it as a List, not an Array
    public List<string> names = new List<string>();
    private string m_selectedName;

    void RandomName()
    {
        if (Input.GetKeyDown(KeyCode.N))
        {
            // Choose a random index
            int num = Mathf.RoundToInt(Random.Range(0, names.Count-1));

            // Save the selected name
            m_selectedName = names[num];

            // Remove from list
            names.RemoveAt(num);
        }
    }

Just modify the name of the method and the way you store the selected name to your needs.
