Show disabled object in scene view

I don't know a good way. I have two ideas.

1. Have your enemy GameObjects enabled in Edit Mode. If you want to hide them at first in the gameplay, hide them by script. For example you may have a GameManager script that hides all the enemies on Start or after the level is loaded.

2. Some editor scripting might help. I tried to write one.

Create a script called LetMeSeeYouGuys with the following content.

 using UnityEngine;
 
 [ExecuteInEditMode]
 public class LetMeSeeYouGuys : MonoBehaviour
 {
     public GameObject[] guys;
 
     public Vector2 buttonSize = new Vector2(100, 25);
     public Vector2 buttonOffset = new Vector2(0, 40);
     public Color buttonGUIColor = new Color(1, 1, 1, 0.8f);
 
     void Awake()
     {
 #if !UNITY_EDITOR
         Destroy(gameObject);
 #endif
     }
 }

Create another script called LetMeSeeYouGuysEditor with the following content. Put it in the same folder as LetMeSeeYouGuys.

 #if UNITY_EDITOR
 using UnityEditor;
 using UnityEngine;
 
 [CustomEditor(typeof(LetMeSeeYouGuys))]
 public class LetMeSeeYouGuysEditor : Editor
 {
     new private LetMeSeeYouGuys target;
 
     void OnEnable()
     {
         target = (LetMeSeeYouGuys)base.target;
     }
 
     void OnSceneGUI()
     {
         if (target.guys == null || target.guys.Length == 0)
             return;
         Camera sceneCam = SceneView.currentDrawingSceneView.camera;
         Handles.BeginGUI();
         Color colorBackup = GUI.color;
         GUI.color = target.buttonGUIColor;
         foreach (GameObject guy in target.guys)
         {
             Vector3 screenPos = sceneCam.WorldToScreenPoint(guy.transform.position);
             Vector2 guiPos = new Vector2(screenPos.x, sceneCam.pixelHeight - screenPos.y);
             Rect buttonRect = new Rect(guiPos - target.buttonSize / 2, target.buttonSize);
             buttonRect.x += target.buttonOffset.x;
             buttonRect.y -= target.buttonOffset.y;
 
             if (GUI.Button(buttonRect, guy.name))
             {
                 // Debug.Log("Clicked!");
                 Selection.activeObject = guy;
             }
         }
         GUI.color = colorBackup;
         Handles.EndGUI();
     }
 
 
     // [DrawGizmo(GizmoType.Selected | GizmoType.NonSelected)]
     // static void DrawGizmoForMyScript(LetMeSeeYouGuys target, GizmoType gizmoType)
     // {
     //     // Cannot detect mouse click here...
     // }
 }
 #endif

In your scene

• Create a GameObject and attach the script LetMeSeeYouGuys.

• Drag your disabled enemies into the Guys list.

• Turn on Gizmos in the Scene view. Now you should see some Gizmo buttons in the Scene view. Click a button to select the enemy GameObject.

Currently the Gizmo buttons only show when the LetMeSeeYouGuys object is selected. Not very handy and I don't know how to solve it. There is a workaround. You can add another Inspector tab.

Now you have another Inspector tab. Select the LetMeSeeYouGuys GameObject and then lock the tab. You can shrink it very small and keep working on the project like usual.
