So, I watched your video. It was really, really quiet, I had to turn up my volume to max and put noise canceling headphones on to really catch it- just so you’re aware for future videos.
For your transition from moving to idle: Your check needs to be “Velocity > 0” as a bool to allow it to transition to moving, and “Velocity <= 0” for your transition from moving to idle.
For the blendspace, you have to pass in Direction and Speed with direction as X and speed as Y judging by the way you’ve set it up.
Do you have this stuff on your Event Graph? This is how you would get those values!
Hope this helps!
