When I update the AnimationPlayer to loop the animation, and I launch the game, they do not loop. One oddity is that my AnimationPlayer node in the scene tree is greyed out? Not sure if this is related to the issue. I noticed after I added the AnimationTree node that is changed.
If this is happening only with the animation player, and from the imported animations on Mannequiny, this is a limitation of the system.
Normally, animations should be set to loop on the imported character automatically. This happens by putting a suffix in their name in Blender before exporting.
Perhaps I can look into it if you would like. Could you upload your Godot project as a ZIP archive to something like Google Drive or Dropbox, and put the link here?
I can look directly at what is happening in Godot and how to fix it.
Wow thanks for the quick response. This is the mannequiny I imported but it seems like the root node and everything under that also are greyed out. I am wondering maybe if something changed in Godot 3.3 that causes this? I am going to take another look, maybe try importing again and following your set up of the scene more closely, and if that doesn't work I will zip it up for you to look at!
Alright so somehow all that happened was that somehow the inheritance hadn't been cleared (or less likely, got reloaded somehow) and so I just had to simply clear the inheritance again and it was no longer greyed out and was properly looping. Thanks for the help!
Glad you could find the solution!
