Unity2D button as child of camera not clickable

Questions & Answers

I have this character that jumps on left click:

public class Punch : MonoBehaviour
{
    public Rigidbody2D rb;
    public bool clicked;
    public Vector2 direction;
    public static Punch instance;

    // Start is called before the first frame update
    void Start()
    {
        instance = this;
        rb = GetComponent<Rigidbody2D>();
        clicked = false;
        direction = new Vector2(500f, 250f);
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButtonDown(0) && (clicked == false))
        {
            rb.AddForce(direction);
            print("left click");
            clicked = true;
        }
    }

In order for the camera to follow this character, I made the camera a child of the character. This works fine. Now I added an object “Button” in the top left corner of the camera and made it a child of the camera to follow the camera exactly (and stay in the top right).

When I use this script on my button:

    private void OnMouseDown()
    {
        Punch.instance.clicked = false;
        print("TEST");
    }

it does not print “Test” or reset the “clicked” variable to false.
If the button is not a child of a camera, but on the same hierarchy as the character, the button works but obviously won’t follow the camera / character.

What am I doing wrong and how can I fix this?

To anyone wondering: I found a solution (or more of a workaround) for this problem myself.

Instead of having a button as a object in the game itself, just create a UI and add the button there. This makes the management way easier and you don’t have to tell the button to follow anything manually.

For the UI Button I am now using this script:

public class Reset_Button : MonoBehaviour
{
    public void ResetButton()
    {
        Punch.instance.clicked = false;
    }
}
