Why doesn't the script work if it's correct?

Question

Unity

I'm trying to imitate real programming, so I break everything into different scripts, but here's the problem. The simplest code works if it is in a script with a character control, but if I write it in another script and also hang it on the character object, like the controller, then it stops working, there is no call to it, as far as I understand. The code is the simplest. (prefab substituted in unity)

public class PutDown : MonoBehaviour
{
    public GameObject prefab;

    public void start() {
            Instantiate(prefab);
    } 
}

Answer 1

Unity is looking for a method Start, you don't have one, so it doesn't work the way you want.
