Assign Undo and Redo shortcuts to the lateral buttons of the mouse while working in the Editor?

Hi,

Title says it all. Here is my poor attempt:

using UnityEngine;
using UnityEditor;

public class UndoRedoToMouse : Editor
{
    public void OnGUI()
    {
        Event e = Event.current;

        if (e.button == 0)
            Debug.Log ("Left click");

        if (e.keyCode == (KeyCode.Mouse3))
        {
            Debug.Log ("Button 3");
            Undo.PerformUndo ();
        }
        if (e.keyCode == (KeyCode.Mouse4))
        {
            Debug.Log ("Button 4");
            Undo.PerformRedo ();
        }
    }
}

What am I doing wrong?

Thanks.

Take a look here: Unity - Scripting API: Editor

The Editor is intended to form the basis of your own custom editors for a specific type of object (see sample code in the above page).

Is that what you are doing, or are you hoping to override the entire editor’s global notion of Undo/Redo?

I don’t think an editor script is a good way to go about accomplishing this goal. I don’t even 100% know that it’s possible to write an editor script that will respond to every input event the mouse sends from anywhere in the Editor.

I would say you should use whatever software your mouse came with to map those buttons to the menu items themselves (or the appropriate key combos).

I should precise that I can’t even see the Debug.Log in the console, which indicates that I can’t even get the event to recognize I’m clicking the mouse buttons while working on my scene. Is the method “OnGUI()” even the correct “space” where I should put it?
This script is placed in an Editor folder but is not attached as a component to any gameobject.

I’m not sure to see what applies to my case in the sample code of the page you linked…
Also I’m not trying to override any notion of Undo/Redo. I just want to have the same effect as when I click Ctrl + Z / Ctrl + Y (or Edit > Undo / Edit > Redo) but with my mouse.

@StarManta
I have a logitech mouse M500 and the program that controls its functionalities is Logitech SetPoint. But I don’t see anywhere allowing me to map these keys specifically for Unity. It works by default as Next / Previous on the internet, so I’m reluctant to change that for the whole mouse. I need it only for Unity.

Update:
So I found the solution to my problem.
Contrary to what I stated previously, it turns out I was able to map the Ctrl + Z and Ctrl + Y with Logitech Setpoint exclusively for Unity. Worked perfectly. No code needed indeed!
Thanks to all !!
