Topic: Allow zooming in Editor when mouse is over UI element

Currently one can only disable the ControlBase completely using the notInteractUnderGUI flag. Me personally I would like to disable dragging the camera when the input started on a UI element, but allow zooming when the user uses the mouse in the editor and the cursor is currently over a UI element. Cheers

Re: Allow zooming in Editor when mouse is over UI element


Something like that:

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;

public class AllowZoomOnGUI : MonoBehaviour
    private OnlineMaps map;

    private void Start()
        map = OnlineMaps.instance;
        map.notInteractUnderGUI = false;
        map.control.OnMapPress += OnMapPress;

    public bool IsCursorOnUIElement(Vector2 position)
        if (GUIUtility.hotControl != 0) return true;
        if (EventSystem.current == null) return false;

        PointerEventData pe = new PointerEventData(EventSystem.current);
        pe.position = position;

        List<RaycastResult> hits = new List<RaycastResult>();
        EventSystem.current.RaycastAll(pe, hits);
        if (hits.Count == 0) return false;

        GameObject go = hits[0].gameObject;
        if (go == gameObject) return false;

        return go.GetComponent<OnlineMapsMarkerInstanceBase>() == null && go.GetComponent<OnlineMapsBuildingBase>() == null;

    private void OnMapPress()
        if (IsCursorOnUIElement(map.control.GetInputPosition()))
            map.control.OnUpdateAfter += CancelMapDrag;

    private void CancelMapDrag()
        map.control.OnUpdateAfter -= CancelMapDrag;
        map.control.isMapDrag = false;
