GameObject is selected in the Scene view when clicked on, even though there is code preventing that

2023.1.X

Fixed

I reverted the change that caused the OnSceneGUI event to exit early after a selection change, restoring the behaviour of previous Unity versions. However, I would not recommend this method of preventing selection changes in the scene view. A more efficient way would be to register a default control to prevent picking from allowing any selection change in the first place. Example: using UnityEngine; using UnityEditor; [CustomEditor(typeof(templateScript))] public class ERTemplateEditor : Editor { void OnSceneGUI() { InterceptPicking(); } // Example code showing how to prevent selection changes from clicking in the Scene View with an object selected. static void InterceptPicking() { var evt = Event.current; var id = GUIUtility.GetControlID(FocusType.Passive); switch (evt.type) { case EventType.Layout: // If the event is left mouse button and no navigation key modifiers are pressed, add a default control. // A default control will let any handles or ui in the scene take priority, but if nothing is closer // it will be chosen as the active control. Since picking is also a default control but tested after // all user code, this gives us the chance to intercept the event. if(evt.button == 0 && !evt.alt) HandleUtility.AddDefaultControl(id); break; case EventType.MouseDown: if (HandleUtility.nearestControl == id) { evt.Use(); GUIUtility.hotControl = id; } break; case EventType.MouseUp: if (GUIUtility.hotControl == id) { evt.Use(); GUIUtility.hotControl = 0; } break; } } }
