Is it possible to detect a collision between a sprite and a UI image?

Questions & Answers
1

I have a stationary sprite with the tag “Player” with a Rigidbody2D (dynamic body type and discrete collision detection) and circle collider 2D.

I also have a moving UI image; also with a Rigidbody2D (dynamic body type and discrete collision detection) and circle collider 2D.

I want to detect when the moving UI Image collides with the sprite, however I’m not getting the print statement inside of the OnCollisionEnter2D() function below whenever I see them collide on the screen.

public class MeteorController : MonoBehaviour
{
    Vector3 newPos;

    // Start is called before the first frame update
    void Start()
    {
        xCoor = transform.localPosition.x;
        yCoor = transform.localPosition.y;

        newXCoor = xCoor * -1;
        newYCoor = yCoor * -1;
        newPos = new Vector3(newXCoor, newYCoor, 0);
    }

    // Update is called once per frame
    void Update()
    {
        transform.Translate(newPos * Time.deltaTime * speed);
    }

    void OnCollisionEnter2D(Collision2D coll)
    {
        if (coll.gameObject.tag == "Player")
        {
            print("PLAYER");
        }
    }
}

im not sure if you can do it with the default setup of a ui.

but if the ui is world space, then it can be the same location as the player in the world and could be detectable as you want using the same mechanics as anyother trigger/collider.
