How to get mouse position in World Space when in Editor Mode

Question

Hi! I've got an enemy that "patrols" left to right between two x coordinates (I'm working in 2D).

The two x coordinates are public variables that I have to set in the Editor.

Currently, I have to move a gameObject where I want my enemy to make a half-turn, copy the X position of the gameObject, and paste it in my enemy public variable.

Is there any easiest way to set coordinates in the editor?

I tried with ContextMenu but given the fact that Coroutines don't run in editor mode, I don't know how to get it to wait for mouse click.

     [ContextMenu ("SetX1")]
     void SetX1 () {
 while (!Input.GetMouseButtonDown(0)) {
 yield;
 }
         print ("Mouse Clicked");
     }

Of course this doesn't work since it's a function and not a coroutine...

Thanks a lot in advance!

(Please forgive my english :) )

I found the solution:

 using UnityEngine;
 using System.Collections;
 using System.Reflection;
 using UnityEditor;
 
 [CustomEditor(typeof(testEditortoWorld))]
 public class myEditor : Editor {
     private static bool m_editMode = false;
     private static bool m_editMode2 = false;
     
     void OnSceneGUI()
     {
         testEditortoWorld test = (testEditortoWorld)target;
         if (m_editMode)
         {
             if (Event.current.type == EventType.layout) {
                 HandleUtility.AddDefaultControl(GUIUtility.GetControlID(GetHashCode(), FocusType.Passive));
             }
             if (Event.current.type == EventType.MouseDown)
             {
                 Vector2 mousePos = Event.current.mousePosition;
                 mousePos.y = Camera.current.pixelHeight - mousePos.y;
                 Vector3 position = Camera.current.ScreenPointToRay(mousePos).origin;
                 test.bord1X = position.x;
                 m_editMode = false;
             }
             Event.current.Use();
         }
         if (m_editMode2)
         {
             if (Event.current.type == EventType.layout) {
                 HandleUtility.AddDefaultControl(GUIUtility.GetControlID(GetHashCode(), FocusType.Passive));
             }
             if (Event.current.type == EventType.MouseDown)
             {
                 Vector2 mousePos = Event.current.mousePosition;
                 mousePos.y = Camera.current.pixelHeight - mousePos.y;
                 Vector3 position = Camera.current.ScreenPointToRay(mousePos).origin;
                 test.bord2X = position.x;
                 m_editMode2 = false;
             }
             Event.current.Use();
         }
         
     }
     public override void OnInspectorGUI()
     {
         DrawDefaultInspector ();
         GUILayout.BeginHorizontal ("box");
             if (m_editMode)
         {
             if (GUILayout.Button("stopen",GUILayout.Width(60)))
             {
                 m_editMode = false;
             }
         }
         else
         {
             if (GUILayout.Button("EditX1",GUILayout.Width(60)))
             {
                 m_editMode = true;
                 m_editMode2 = false;
             }
         }
         if (m_editMode2)
         {
             if (GUILayout.Button("stopen",GUILayout.Width(60)))
             {
                 m_editMode2 = false;
             }
         }
         else
         {
             if (GUILayout.Button("EditX2",GUILayout.Width(60)))
             {
                 m_editMode2 = true;
                 m_editMode = false;
             }
         }
         GUILayout.EndHorizontal();
     }
 }

testEditortoWorld being my enemyScript and bord1X and bord2X the coordinates variables
