Creating a hotkey to get into "Edit Collider" mode

Is there a way to create a hotkey to get into "Edit Collider" mode of a polygon collider 2d?

 

You should look at UnityEditorInternal.EditMode. There are EditMode.ChangeEditMode & EditMode.QuitEditMode.

 

Thanks, that just might to be the solution. I don't quite know how to make it work though, I see no info on this on the Unity documentation. Do you know more about this?

Code (CSharp):

1. private static void EditCollider()
2.         {
3.             var sel = Selection.activeGameObject;
4.             var col = sel.GetComponent<PolygonCollider2D>();
5.             if (!col) return;
6.  
7.             UnityEditorInternal.EditMode.ChangeEditMode(EditMode.SceneViewEditMode.Collider, , UnityEditor.Editor.CreateEditor(sel));
8.             Debug.Log("EditMode: " + UnityEditorInternal.EditMode.editMode);
9.         }

 

I think you can hook into the Event system to capture current events and keycodes but another way is to make a MenuItem and assign a hotkey chord to it, then Unity will automatically pick it up.

Code (csharp):

1. [MenuItem ("Edit/Custom/Edit Collider Mode #_e")] // This is Shift + e
2. private static void EditCollider()
3.         {
4.             var sel = Selection.activeGameObject;
5.             var col = sel.GetComponent<PolygonCollider2D>();
6.             if (!col) return;
7.  
8.             UnityEditorInternal.EditMode.ChangeEditMode(EditMode.SceneViewEditMode.Collider, , UnityEditor.Editor.CreateEditor(sel));
9.             Debug.Log("EditMode: " + UnityEditorInternal.EditMode.editMode);
10.         }

 

Yea that's pretty cool but the issue here really is the code I shared. It doesn't work because I'm not sure what to fill this line of code with:

Code (CSharp):

1. UnityEditorInternal.EditMode.ChangeEditMode

 

This code works, enjoy!

Code (csharp):

1.  
2. [MenuItem("Edit/Custom/Edit Collider Mode #_e")] // This is Shift + e
3. private static void EditCollider()
4. {
5.     var sel = Selection.activeGameObject;
6.     var col = sel.GetComponent<Collider2D>();
7.  
8.     if (!col)
9.         return;
10.  
11.     if (UnityEditorInternal.EditMode.editMode == EditMode.SceneViewEditMode.Collider)
12.     {
13.         UnityEditorInternal.EditMode.ChangeEditMode(UnityEditorInternal.EditMode.SceneViewEditMode.None, new Bounds(), null);
14.     }
15.     else
16.     {
17.         Type colliderEditorBase = System.Type.GetType("UnityEditor.ColliderEditorBase,UnityEditor.dll");
18.         Editor[] colliderEditors = Resources.FindObjectsOfTypeAll(colliderEditorBase) as Editor[];
19.  
20.         if (colliderEditors == null || colliderEditors.Length <= 0)
21.             return;
22.  
23.         UnityEditorInternal.EditMode.ChangeEditMode(UnityEditorInternal.EditMode.SceneViewEditMode.Collider, col.bounds, colliderEditors[0]);
24.     }
25.    
26.     Debug.Log("EditMode: " + UnityEditorInternal.EditMode.editMode);
27. }
28.  

 

Great! Thank you!

 

Great script, but the hotkey is not working in MacOS. However using "%e" works for CMD+E. Also you should also check if sel is null, so it won't error, if there is no object selected.

 

I'm using Unity 2019.3.0f6 and when I step through this script in the debugger it is changing the value of "UnityEditorInternal.EditMode.editMode" but not opening edit mode. Can anyone get this working in a new version of unity?

Also just double checking, is the expected behavior of the script above the same as clicking on the button in the attached screenshot?

 

Try this:

Code (CSharp):

1. [MenuItem("Tools/Edit Polygon Collider")]
2.     static void edit_polygon_collider() {
3.         var assemblies = AppDomain.CurrentDomain.GetAssemblies();
4.         foreach (var assembly in assemblies) {
5.             if (assembly.GetType("UnityEditor.PolygonCollider2DTool") != null) {
6.                 UnityEditor.EditorTools.EditorTools.SetActiveTool(assembly.GetType("UnityEditor.PolygonCollider2DTool"));
7.             }
8.         }
9.     }

In settings, bind this hot function to any shortcut you want.

 

in u2022 SetActiveTool is now using ToolManager instead of EditorTools :

Code (CSharp):

1.  
2.     using UnityEditor.EditorTools;
3.     (...)
4.     ToolManager.SetActiveTool(type);
5.  

Any idea on how to do the same to edit Spline of SpriteShapeController ?
I searched in the assemblies for various types (like PolygonCollider2DTool) that would be compatible but couldn't find the right one to feed to the ToolManager.

Thanks

 

You can get the type of the active tool via:

Code (CSharp):

1. Debug.LogError("Active tool type: " + UnityEditor.EditorTools.ToolManager.activeToolType);

Put that in an editor function with a shortcut, select your object, enable the tool, then log the name of it.

That's how I was able to find the tool names for sphere and box colliders: "UnityEditor.BoxPrimitiveColliderTool" and "UnityEditor.SphereColliderTool"

Code (csharp):

1.  
2. [MenuItem("DoomTurtle/Tools/Edit Collider Mode #_e")] // This is Shift + e
3. static void EditCollider()
4. {
5.     var EditorTypes = typeof(EditorTool).Assembly.GetTypes();
6.  
7.     var SelObj = Selection.activeGameObject;
8.     if (SelObj)
9.     {
10.         var BoxToolType = EditorTypes.FirstOrDefault(x => x.FullName == "UnityEditor.BoxPrimitiveColliderTool");
11.         var SphereToolType = EditorTypes.FirstOrDefault(x => x.FullName == "UnityEditor.SphereColliderTool");
12.  
13.         if (SelObj.GetComponent<BoxCollider>())
14.         {
15.             UnityEditor.EditorTools.ToolManager.SetActiveTool(BoxToolType);
16.         }
17.         else if (SelObj.GetComponent<SphereCollider>())
18.         {
19.             UnityEditor.EditorTools.ToolManager.SetActiveTool(SphereToolType);
20.         }
21.     }
22.  
23.     //Debug.LogError("Active tool type: " + UnityEditor.EditorTools.ToolManager.activeToolType);
24. }
25.
