Is EventSystems.EventSystem.IsPointerOverGameObject deprecated in Unity 2019.3?

Question

I am looking to detect if my cursor is on top of any UI elements (GameObject). I want to prevent running a function by checking if my cursor is on top of any UI Element.
The function looks like this:

   if (!pointerIsOnTopOfEvent) {
    return;
    } **// if the pointer here is on top of any UI element, stop doing the rest of the code**

    if (build_Manager.GetFarmObjectToBuild()== null)
    {
        return;
    }
    nodeRender.material.color = hoverColor;

I really appreciate it if someone has other methods if EventSystems.EventSystem.IsPointerOverGameObject is deprecated.

If you don’t mind the new Input System it has an isPointerOverGameObject method.

This looks like the deprecated method in question. Do you have a solution for 2019.3?

I don't think is deprecated, it works on 2020.3 version. (Or maybe they decided to put it back.)

I have discovered that it is NOT deprecated, or at least not completely. In the documentation, you’ll notice UnityEngine.EventSystems is missing after 2019.1. Why this is, i don’t know.

However, you can still get at IsPointerOverGameObject by way of EventSystem.current.IsPointerOverGameObject(), and make sure you are using UnityEngine.EventSystem.

Try this

private bool IsPointerOverUIObject() {
        PointerEventData eventDataCurrentPosition = new PointerEventData(EventSystem.current);
        eventDataCurrentPosition.position = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
        List<RaycastResult> results = new List<RaycastResult>();
        EventSystem.current.RaycastAll(eventDataCurrentPosition, results);
        return results.Count > 0;
}
