My custum event don't play animation in HUD

Please make new “comments” not answers as it clutters the thread. That being said, have you tried printing a string after the switch call (after the create widget node print a string, make sure that is firing) and second try printing a string within the widget after the “switch” event. Make sure it is getting called. This will tell you if it is an issue executing the command to fire the custom event or an issue with the animation nodes.
