public class MouseExample : MonoBehaviour
{
    void Update()
    {
        // Check if the left mouse button was clicked
        if (Input.GetMouseButtonDown(0))
        {
            // Check if the mouse was clicked over a UI element
            if (EventSystem.current.IsPointerOverGameObject())
            {
                Debug.Log("Clicked on the UI");
            }
        }
    }

public class TouchExample : MonoBehaviour
{
    void Update()
    {
        // Check if there is a touch
        if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
        {
            // Check if finger is over a UI element
            if (EventSystem.current.IsPointerOverGameObject(Input.GetTouch(0).fingerId))
            {
                Debug.Log("Touched the UI");
            }
        }
    }
}

If you use IsPointerOverGameObject() without a parameter, it points to the "left mouse button" (pointerId = -1); therefore when you use IsPointerOverGameObject for touch, you should consider passing a pointerId to it.

Note that for touch, IsPointerOverGameObject should be used with OnMouseDown() or Input.GetMouseButtonDown(0) or Input.GetTouch(0).phase == TouchPhase.Began.

매개 변수없이 IsPointerOverGameObject()를 사용하면 "마우스 왼쪽 버튼"(pointerId = -1)을 가리 킵니다. 따라서 touch에 IsPointerOverGameObject를 사용할 때는 pointerId를 전달하는 것을 고려해야합니다.

touch의 경우 IsPointerOverGameObject는 OnMouseDown () 또는 Input.GetMouseButtonDown (0) 또는 Input.GetTouch (0) .phase == TouchPhase.Began과 함께 사용해야합니다.
