Manually Update/Redraw Scene View?

Question

I have a GameObject whose gizmo is drawn differently depending on certain properties of the GameObject which are modified through a custom editor I've created for it. As it is now, if I modify one of the properties, the gizmo isn't redrawn until I click in the scene view. Is there any way to manually update the either the scene view or just the gizmo when one of the properties is modified?

SceneView.RepaintAll(); You can try this, it works for me.

This is the solution that works, HandleUtility.Repaint() doesn't do the trick, as commented before

This should be the accepted answer!

This doesnt work, nor any of those:

 Canvas.ForceUpdateCanvases();
 EditorWindow.GetWindow( Type.GetType( "UnityEditor.GameView,UnityEditor" ) ).Repaint();
 SceneView.RepaintAll();
 EditorWindow.GetWindow<SceneView>().Repaint();
 HandleUtility.Repaint();

I need to grab a side of a window and resize it a little bit. Only then the window actually redraws. But I would like to do this from code.

You should use this code:

if (GUI.changed) EditorUtility.SetDirty (target);

For more details see the documentation "LookAtPointEditor.js"

This works although it marks the scene as unsaved. In my case I need to redraw the scene when the user changes the current tool in the inspector, which obviously doesn't make any change to the component itself. But the scene must be redrawn to display a different set of handles. But I guess I can live with it :)

+1, this worked for me. Agreed on not liking the dirtying of the scene, but I can also live with it. Has anyone filed a bug report about HandleUtility.Repaint not doing what it seems like it ought to?

I force it without the condition. EditorUtility.SetDirty (target); Works perfect!

I believe HandleUtility.Repaint does what you want.

This only works in the editor. You can not build the project with this code in it. Any other ideas?

Should be in Editor folder of your scripts as it is editor functionality, you don't have a scene view in final build, so what use would it be to have it compiled in project.

It sounds like it should do what the OP wants, but it doesn't seem to work. I have the same issue. HandleUtility.Repaint doesn't refresh my scene view (I'm on Unity 3.3 on a Windows PC).

You can use EditorUtility.SetDirty(target) to update handles. But, to avoid to mark the scene aways as unsaved, you must do a trick like this:

 var int lastValue = someValue;
 
 someValue = EditorGUILayout.IntField("Value", someValue);
 
 if (someValue != lastValue) {
     EditorUtility.SetDirty(target);
 }

Recently I implemented a Spawn system that have a custom inspector. Here is the inspector in action: http://gyazo.com/5c2f5f12a1d60e950aa62f21629f9866

This worked for me.. Other solutions did not (UI Text was failing to redraw in its new position straight away when it's parent ganeObject moved in the Editor).

This worked for me, although I changed the condition a bit:

     if(Event.current.rawType == EventType.$$anonymous$$ouse$$anonymous$$ove ||
        Event.current.rawType == EventType.$$anonymous$$ouseEnterWindow ||
        Event.current.rawType == EventType.$$anonymous$$ouseLeaveWindow)
     {
         EditorUtility.SetDirty(target);
     }

First you need to set the Gameobject as dirty, then repaint.

 GameObject targetGameObject;
 EditorUtility.SetDirty(targetGameObject);
 SceneView.RepaintAll ();

This may also help other future readers:

I confirm this answer works, only call RepaintAll() cannot auto-refresh the scene (at lease when I edit the prefab), add SetDirty makes it auto-refresh the scene.
