Scene Gizmo Hotkeys

Question

To align your editor's scene window view to an axis, it is arduous to find the corresponding leg of the Scene Gizmo and click it with the mouse:

Are there keyboard shortcuts for the axes, akin to Numpad 1, 3, and 7 in Blender?

If not, how might one implement them with an editor script?

Couldn't find any hotkeys myself, but it is possible to make a script to do it.

 using UnityEngine;
 using UnityEditor;
 using System.Collections;
 
 class GizmoTest {
     
     [MenuItem ("Gizmo/Front View _1")]
     static void FrontView () {
         GetSceneView().orthographic = true;
         GetSceneView().LookAtDirect(GetSceneView().pivot,
             Quaternion.LookRotation(Vector3.forward));
     }
     
     
     [MenuItem ("Gizmo/Side View _3")]
     static void SideView () {
         GetSceneView().orthographic = true;
         GetSceneView().LookAtDirect(GetSceneView().pivot,
             Quaternion.LookRotation(Vector3.right));
     }
     
     [MenuItem ("Gizmo/Top View _7")]
     static void TopView () {
         GetSceneView().orthographic = true;
         GetSceneView().LookAtDirect(GetSceneView().pivot,
             Quaternion.LookRotation(Vector3.down));
     }
     
     [MenuItem ("Gizmo/Perspective View _5")]
     static void PerspectiveView () {
         GetSceneView().orthographic = !GetSceneView().orthographic;
         GetSceneView().LookAtDirect(GetSceneView().pivot,
             Quaternion.LookRotation(Vector3.forward + Vector3.right + Vector3.down));
     }
     
     static SceneView GetSceneView() {
         SceneView activeSceneView = null;
         
         if (SceneView.lastActiveSceneView != null) {
             activeSceneView = SceneView.lastActiveSceneView;
         }
         else if (SceneView.sceneViews.Count != 0){
             activeSceneView = (SceneView.sceneViews[0] as SceneView);
         }
         
         return activeSceneView;
     }
 }

This script will work on all the numbers of the keyboard, don't know if there is any way to only check numpad.

Saving it as "GizmoTest.cs" in the Editor folder, I'm getting this error for each of the four menu entries:

Assets/Editor/GizmoTest.cs(8,23): error CS1061: Type UnityEditor.SceneView' does not contain a definition for LookAtDirect' and no extension method LookAtDirect' of type UnityEditor.SceneView' could be found (are you missing a using directive or an assembly reference?)

Also I'm not seeing an entry for "SceneView" in the scripting reference. Where is that defined?

Weird. $$anonymous$$aybe it's something new in 3.5? If you use an older version.

But if it's just a problem with LookAtDirect, change it to LookAt. That one looks cooler anyway :)

Indeed I was still on 3.4.0f5. I didn't realize 3.5 was out of beta. Score.

After upgrading, it works now. Looks like they still haven't updated the docs yet though; SceneView and LookAtDirect() don't show up in the scripting reference. Where did you find out about them? And yes, LookAt() smoothly interpolates between views. :)

Good job. To mimic Blender more precisely, 3 would have you looking toward Vector3.left (not right), and 5 would toggle ortho and perspective like you have it but it's not necessary to also change the view there. Thus $$anonymous$$e is now:

 using UnityEngine;
 using UnityEditor;
 using System.Collections;
 class GizmoTest{
     [$$anonymous$$enuItem("Gizmo/Front View _1")]
     static void FrontView(){
        GetSceneView().orthographic=true;
        GetSceneView().LookAt(GetSceneView().pivot,Quaternion.LookRotation(Vector3.forward));
     }
     [$$anonymous$$enuItem("Gizmo/Side View _3")]
     static void SideView(){
        GetSceneView().orthographic=true;
        GetSceneView().LookAt(GetSceneView().pivot,Quaternion.LookRotation(Vector3.left));
     }
     [$$anonymous$$enuItem("Gizmo/Top View _7")]
     static void TopView(){
        GetSceneView().orthographic=true;
        GetSceneView().LookAt(GetSceneView().pivot,Quaternion.LookRotation(Vector3.down));
     }
     [$$anonymous$$enuItem("Gizmo/Perspective View _5")]
     static void PerspectiveView(){
        GetSceneView().orthographic=!GetSceneView().orthographic;
     }
     static SceneView GetSceneView(){
        SceneView activeSceneView=null;
        if(SceneView.lastActiveSceneView!=null)activeSceneView=SceneView.lastActiveSceneView;
        else if(SceneView.sceneViews.Count!=0)activeSceneView=(SceneView.sceneViews[0] as SceneView);
        return activeSceneView;
     }
 }

I'll let you know if I find a way to specify numpad keys as shortcuts, unless someone else chimes in.

Crap, I just realized it eats your 1, 3, 5 and 7 keys even when you're trying to type values into Inspector fields. We'll have to bind them to something else until we figure out how to differentiate between numpad keys and keyboard numbers for shortcuts.

Edit: I discovered you can code it as "_Numpad 1" but that has the exact same effect as just "_1". Weird.

I didn't think about that :) As i always use the numpad for entering values changing to only affect numpad won't cut it for me, so i did a check for if the sceneview is the active window ins$$anonymous$$d.

Just add this in the GetSceneView-function

if (EditorWindow.focusedWindow != activeSceneView) activeSceneView = null;

and do a check for if GetSceneView==null in the View-functions by adding

if (GetSceneView() == null) return;

in the first line.
