How can I make random numbers through a sprite?

Question

C++ / C#

public TextMesh tm;
    Rigidbody2D rb;
  void Start ()
    {
        rb = GetComponent<Rigidbody2D>();
        tm = GameObject.Find("numBug").GetComponent<TextMesh>();
        tm.text = Random.Range(1, 255);
    }

tried that, but it doesn't work. What to do?

Answer 1

If I understand correctly, then tm.text is of type string, and Random.Range(1,255) is of type int, and you are assigning int to string. Try this:
tm.text = Random.Range(1, 255).ToString();
