Undo not working?

nicmar · 2019年7月2日

Hi, I saw an old thread about Undo not working on OS X, and it just happened to me on 3.7.94 Pro.

I don't think it's the hotkeys or keyboard layout, since I see the undo arrows blink when I press Cmd-Z or Shift-Cmd-Z. But even if I click the arrows, the undo is not working.

This was only a test I was trying out, but if it was a real project it would be pretty horrible if this happened. Check the video for what it looks like:

After restarting Spine, Undo works as it should, but why does it happen?

Thanks!

That is very strange. We've spent countless hours with Spine but have never seen this before! That you clicked the buttons ensures it's not some problem with hotkeys firing. The button directly invokes the undo system to perform the undo. The only time undo does nothing is if there are no actions to undo. Translating a bone always generates such an action, so I'm really at a loss as to what it could be. :confused: Please let us know if you see it happen again. It would be especially helpful if you took note of what actions you might have been doing prior to this problem occurring.

Sure, first time for me too so hopefully nothing. I worked with first making a mesh of an image with a single slot and sprite, then binding bones to it, and finally trying to adjust the bones using the compensate image feature.

Also I had by mistake hidden bones with the bones eye icon so I enabled that. Somewhere after that I messed up the bones and wanted to undo.

That’s what I remember but if I can recreate it in more detail in the future I’ll let you know.
