Widget Play animation reverse is broken.

Development Programming & Scripting Blueprint

I’m making a widget that plays forwards or backwards depending on the situation, but I’m having problem with playing in reverse.
When I play forward it works fine, but when I play backwards it jumps straight to the first frame.
(And I also noticed that PlayAnimationReverse and Forward don’t work at all)
I think I’ve set up the nodes properly, so what’s wrong?

Maybe look at the source animation and it’s settings regarding transition time.
Also time to start will be different in reverse.

I don’t think there’s a problem there.
There are only keyframes at the start and end.
The last frame and animation duration are the same.

About the transition time, I thought for a moment that it was an actor animation not a widget

Here is a smooth forward / reverse example. Just swap out the animation for your own.

In reverse you can’t set the elapsed time but you need to subtract it from the end time (so the full length)

Oh I see.
I forgot to subtract. Maybe that was the problem.
Thank you for your help.
