The animations of my enemy don't play in game

Hi! I’ve started working on the AI of a monster and so far he can follow me if I enter his line of sight. However, he just slides towards me on the ground while playing his idle animation instead of walking. It makes no sense to me since I’ve created an anim blueprint and a blendspace, then I’ve set everything up by carefully following tutorials. Here’s a few screenshots, maybe I made a mistake somewhere

I really hope someone can help me, this is ruining my day. :frowning: Thank you for your time.

You didn’t plug in the output of VectorLength into Set Speed.

Thanks! It’s working now. :o
