Requires Unity 2019.2 or later.
This Unity project/package contains a template you can build on to create a custom "mutli-page" Editor Window. You can create multiple "panels" for the window (each in a separate file), and use the navigation system provided. Navigation includes the ability to switch between panels smoothly using a "sliding" animation (based on Unity's AnimationCurves).
Disclaimers:
- Currently doesn't serialize the windows correctly, so a recompile will crash the windows. This can be fixed by switching the windows over to using ScriptableObjects.
- Navigation works in a stack but only supports backwards navigation. No forward navigation if you go back a page, but then want to return to the previous page.
Either clone the repository and open the included Unity project in Unity 2019.2 or later.
OR download the Unity package file and import it into your own project.
You can open the custom editor window by going to the top menu bar and selecting Window > Editor Window Navigation Demo. This menu item can be changed to your own within Assets/Editor/Scripts/MenuItems.cs.
You can also change the window title in Assets/Editor/Scripts/MainWindow.cs.
You can create your own panel by creating another .cs file in the Assets/Editor/Scripts/Panels folder. The panel must inherit from PanelBase and the panel content can be drawn using standard GUILayout methods in the overriden Render() method (treating it like the standard OnGUI method).
You can also change the background colour of the panel by overriding GetBackgroundColor().
See the included WelcomePanel and ColourPanel examples included.
The WelcomePanel is created and displayed by default. You can change this on line 33 of Assets/Editor/Scripts/PanelManager.cs.
Navigation works using the following methods:
PanelManager.Navigate - Transition to a new panel. The previous panel gets added to the stack, so backwards navigation can be used.
PanelManager.ChangePanel - Transition to a new panel without changing the stack. Use this if you want to transition to a new panel which shouldn't be added to the stack (i.e. the user shouldn't be able to return to it from later panels).
PanelManager.Back - Use this to transition back to the previous panel in the stack.
PanelManager.ClearStack - Remove all previous panels from the stack to prevent the user navigating back. (e.g. after a user logs in via a login panel, you may want to use this to prevent the user going back to the login screen via a back button).
