How can I get the PointerEventData included in StandaloneInputModule ?

Hi guys,

I want to access to the "PointerEventData" object which is part of the "StandaloneInputModule" in Unity, in order to know which gameobject is pointed at each frame. (Not necessarily those with a collider, but also UI gameobjects etc...)

The problem is that the PointerEventData included in the StandaloneInputModule is declared as a protected property.

So I created this class, which inherits from StandaloneInputModule :

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 using UnityEngine.EventSystems;
 
 public class StandaloneInputModuleCustom : StandaloneInputModule
 {
 
     public PointerEventData GetLastPointerEventDataPublic(int id)
     {
         return GetLastPointerEventData(id);
     }
 }

Using this, I have access to all the informations I need at each frame. And I can know which gameobject is touched etc... by using this PointerEventData getter.

It works perfectly in the editor, but when I start the game on Android or iOS after building it, I get a NullReferenceException at the moment I call the "GetLastPointerEventDataPublic" method.

It just doesn't work with a real build, I cannot access to the PointerEventData of the StandaloneInputModule, except in the editor.

Does anyone knows why ?

Thank you :)
